Personal Advertisements

Broadly speaking, an advertisement is a form of communication intended to promote the sale of a product, or a service to influence public opinion, advance a particular cause, gain political support, to elicit some other response desired by the advertiser. It is also used indirectly to enlighten the public at large about new products and services.
The characteristics of an advertisement are :

  • Catching attention
  • Stimulating interest
  • Arresting desire
  • Supplying convincing details
  • Motivating action

We sometimes find it necessary to place personal advertisements (or ads) in newspapers. The publication of these ads are expensive. Therefore, it is necessary to be brief and concise in writing an ad.

CHSE Odisha 11th Class English Grammar Story Developing

A. Introduction:

A story is made up of a number of events or happenings. Let us look at your own story or part of it. On Sundays, I get up at six in the morning. After a quick wash, I get into my jugging rig and go for a run. By 6.30 I am on the road. I run for half an hour. I return home and have a leisurely bathing, a luxury I cannot afford on weekdays. The bath is over, I get ready quickly. What have you done? You have described the events or your activities on a Sunday morning, in the order in which they take place. You can start with what you do first, then go on to what you do next, and so on until you come to your test activity.

B. A beginning, a middle, and an end:

Like any other piece of information, a story has a beginning, a middle, and an end – it is a complete whole. It invites you and opens the door for you; then it leads you through the plot; and finally, it shows you out at the exit, you walk out happy and satisfied and a door gently shuts behind you. The story ‘Jangled Bells’ is a case in point. It shows three stages. The transition from one stage to the next is not abrupt or sudden; it is smooth and natural.

CHSE Odisha Class 11 English Grammar Story Developing

C. The beginning of a story:

How a story begins is very important. The beginning should catch the reader’s attention and urge him to read on. It should set the scene for the action and the mood.

D. Sequence of events:

A story is the narration of action. All action occurs in time. The most natural way of narrating a story is to give the events strictly in the order in which they happened; with one event leading naturally and logically to the next. “What happened then ?” is the question the storyteller should ask himself at every stage.

E. Paragraphing a story:

The events in a story will fall into a few clusters of happenings, each cluster will have unity of time, place, and action. Each cluster can be put into a paragraph. Paragraphing a story is really a simple thing. Just remember that each paragraph tells one part of the story.

F. The Background:

The story must have a background in which the plot takes place. The background is usually set at the very beginning: It is sometimes done through descriptions of the place, the season, the time, etc. The descriptions should be rich in sensory impression — the reader should see, hear, smell, taste, and feel the atmosphere.

For example:
I was traveling across the desert with Mehmood Ah and his caravan of eighty camels and eighteen men. Ah was a dignified old man with fierce dark eyes and a white beard. His commands were the only laws that the men of the caravan knew.
How is the scene of the story set? (desert, caravan — camels, men, etc.)

CHSE Odisha Class 11 English Grammar Story Developing

G. The characters in a story:

The characters are the people in the story. The story is about ‘them — what they do. how they feel, what they say, etc. The characters must seem to be alive and doing things — not just moving through the story like puppets. They must look like people we see in real life; they must be believable. Each character should have special traits. The way he tells, the way he feels, and the way he reacts to things must be distinctly his own. Only then would he become an individual, not just one of the crowd.

H. Attitude:

She did the right thing!
That was an awful thing to do!
‘Poor woman! How she suffered at his hands?’

These are three different reactions to what someone did: approval, condemnation, and sympathy. But the action was the same; the difference is in the way the three people looked at it. It is the storyteller’s attitude that can change the story very much.

I. Dialogue:

It is possible for the storyteller to report what the characters say. But if this is done throughout he story it can become monotonous. Quoting the actual words of the characters will inject life into the story.

J. The end of a story:

A story must have a natural and definite ending. It should come to an end, not just stop suddenly. It should not leave the reader in the air – unhappily and wondering. The ending should give the feeling of completeness like the final knot on a garland of flowers.

Questions :

Question 1.
Complete a story that ends with the following paragraph :
The tail of the plane was in flames and the pilot knew he would not be able to land safely. There was another loud bang somewhere behind him. He made up his mind. He pulled the rip cord. In seconds he found himself sailing through space, the parachute billowing above him. Below him, he saw the plane crash on the field and explode like a bomb.

CHSE Odisha Class 11 English Grammar Story Developing

Answer:
Nick was bored with life. Everybody was exactly the same. He now wanted to break the monotony. It was summer vacation. He decided to go to Kashmir to enjoy its picturesque details. He arranged a plane ticket for the purpose. It was Sunday. He woke up at 6.30. The sun was shining, and the birds were singing. A gentle breeze was blowing. He got ready to catch up on his flight at 9.30. He. reached the airport one hour before the take-off time.

Nick’s mind wandered in the beautiful valley. His spirit soared. He was looking at his watch on and on. The moment he had been waiting for had come at last. The loudspeakers announced her flight. With a heart of excitement, Nick boarded the plane and sat near the window. The plane took off. Nick looked out of the window. What a beautiful sight! All of a sudden, ominous whispering among the passengers caught his attention. Then they gave loud shrieks. Nick felt terribly confused.

To his stunned disbelief, Nick noticed the plane swing violently. The tail of the plane was in flames and the pilot knew he would not be able to land safely. There was another loud bang somewhere behind him. He made up his mind. He pulled the rip cord. In seconds he found himself sailing through space, the parachute billowing above him. Below him, he saw the plane crash on the field and explore like a bomb.

Question 2.
The day was fine and the clock struck nine. I had an interview at ten. What if I got late? I was in the middle of a busy street, (continue …………)

Answer:
The day was fine and the clock struck nine. I had my interview at ten. What if I got late? I was in the middle of a busy street. The vehicles moved at a snail’s pace. I was getting more and more tensed. If I couldn’t make it, my career would be at stake. I had no other option but to wait. I checked out my watch. “God ! it was already 9.30.” My heart started hammering within my ribs. I had to do something. Just then I was reminded of a narrow lane some yards away which was a shortcut.

With much difficulty, I parked my car. But that was not the end to my problems. The traffic police stopped me for the wrong parking. When the senior officer came, I explained the situation to him. Thankfully, he understood and even helped me get there. When I reached there it was just two minutes to ten. I heared a sigh of sweet relief. The moment of truth came at last. 1 was called for the interview. It was a hectic one. I responded to the questions of the members with a great deal of confidence.

They shook hands with me. I noticed smiles on their faces at the time of my departure. A thrilling experience indeed! A month passed by. I had been waiting for the moment when my appointment would come. Sincerity never goes unrewarded. The moment I had been waiting for came at last. I got my appointment letter. Excitement was in the air. I was really on the moon. That day’s experience still lingers in my memory.

Question 3.
Provide a suitable ending to the following story.
As Sandhya was sitting on the steps at the temple two terrorists appeared. They were armed with AK-56 rifles and hand grenades. She was driven into panic at their sight. To her horror, she found them entering the temple. They fired their shots indiscriminately. The silent prayers of the devotees turned into wailing in a flash. Thousands of them ran hither and thither to save themselves from the brutal attacks of the two dreaded terrorists.

The pitiable cries of women and children moved Sandhya to tears. She was fortunate to leave that spot in a flash. I stood at a distance and was a silent spectator to the ghastly scene. They killed 29 innocent devotees and 3 children and injured 74 others. In the night-long operation to flush out the terrorists, the national security guards lost two of its commandos and the State Reserve Police two of its personnel, the terrorists were killed early the next morning.

Answer:
Whenever we meet by chance, Sandhya tells me she cannot forget the harrowing moment of that day. She still remembers when she was having a close look at the snow-white Akshardham temple, sitting on its marble steps. It is the pride of the Swaminarayan Sect. The bloodshed in the place of worship, which stands for universal peace and brotherhood has left many questions unanswered. There should be conceited efforts to eliminate terrorism for all time to come.

Question 4.
Provide a suitable beginning to the story.
At last, a foolish Brahmin passed by that way. Seeing him the tiger begged him to let him come out from the cage. He took pity on the tiger and opened the door of the cage. As soon as the door was opened the tiger came out and wanted to eat the Brahmin. The Brahmin now realized that he had acted foolishly. However, he told the tiger that he had done a good service to him, so he should not eat him. But the ungrateful tiger would not listen to his argument.

He said that he was very hungry. So he must eat him. The Brahmin was quite helpless. At this time a fox came there. He heard from the Brahmin what had happened. He wanted to decide the matter. But first of all, he must see how the tiger got into the cage and how the Brahmin helped him to get out. They agreed. The tiger then got into the cage through the open door. The fox then shut the door.

The tiger was thus again trapped in the cage. The fox now asked the Brahmin to throw the cage into the river. He called other men to help him. They heard the story and dragged the cage to the bank of the nearby river. Then they threw it into the water. The ungrateful tiger was drowned. Thus, the clever fox saved the foolish Brahmin’s life.

Answer:
Once a tiger was caught in a cage. He tried much to get out. The door of the cage was shut and the iron bars of the cage were very strong. So he could not come out. He asked the passers-by to let him out. But none dared to do so. They feared that the tiger would eat them if he could come out once.

CHSE Odisha Class 11 Math Solutions Chapter 16 Probability Exercise 16(b)

Question 1.
A school has six classes 1, 2, 3, 4, 5, and 6. Classes 2, 3, 4, 5, and 6 each have the same number of students, but there is twice this number in class 1. If a student is selected at random from the school, what is the probability that he(she) will be in
Solution:
A school has six classes 1, 2, 3, 4, 5, and 6. Classes 2, 3, 4, 5, and 6 each have the same number of students, but there is twice this number in class 1.
Let the number of students in class 2, 3, 4, 5, and 6 is x each and the number of students in class 1 is 2x.
∴ The total number of students = 7x.
A student can be chosen from 7x students in 7xC1 = 7x ways.
∴ |S| = 7x.

(i) class 1
Solution:
Probability that the student belongs to class 1, is \(\frac{2 x}{7 x}=\frac{2}{7}\)

(ii) class 2
Solution:
Probability that the student belongs to class 2, is \(\frac{x}{7 x}=\frac{1}{7}\)

Question 2.
Let a die be weighed in such a way that the probability of getting a number n is proportional to n.
Solution:
Let a die be weighed in such a way that the probability of getting a number n is proportional to n.
Let the constant of proportionality be k.
∴ P(n) = nk so that P(1) = k
P(2) = 2k, P(3) = 3k,…. P(6) = 6k
∴ P(1) + P(2) +…….+ P(6) = 1
or, k + 2k +……..+ 6k = 1
or, 21 k = 1 or, k = \(\frac{1}{21}\)

(i) Find the probability of each elementary event.
Solution:
P(1) = \(\frac{1}{21}\), P(2) = \(\frac{2}{21}\), P(3) = \(\frac{3}{21}\), P(4) = \(\frac{4}{21}\), P(5) = \(\frac{5}{21}\) , P(6) = \(\frac{6}{21}\)

(ii) Find the probability of getting an even number in a single roll of the die.
Solution:
= P(2) + P(4) + P(6)
= \(\frac{2}{21}+\frac{4}{21}+\frac{6}{21}=\frac{12}{21}\)

CHSE Odisha Class 11 Math Solutions Chapter 16 Probability Ex 16(b)

(iii) Find the probability of getting a prime number in a single roll of the die.
Solution:
= P(1) + P(3) + P(5)
= \(\frac{1}{21}+\frac{3}{21}+\frac{5}{21}=\frac{9}{21}\)

(iv) Find the probability of getting a prime number in a single roll of a die.
Solution:
Probability of getting a prime number = P(3) + P(5) + P(2)
= \(\frac{3}{21}+\frac{5}{21}+\frac{2}{21}=\frac{10}{21}\)

Question 3.
Five boys and three girls are playing in a chess tournament. All boys have the same probability p of winning the tournament and all the girls have the same probability q of winning. If p = 2q, find the probability that
(i) a boy wins the tournament.
(ii) a girl wins the tournament.
Solution:
5 boys and 3 girls are playing a chess tournament. All boys have the same probability P of winning the tournament and all the girls have the
same probability q of winning.
We have P(B) =p, P(G) = q.
As there are 5 boys and 3 girls,
we have 5p + 3q = 1
Now putting p = 2q,
we have 10q + 3q = 1
or, q = \(\frac{1}{13}\) ∴ p = 2q = \(\frac{2}{13}\)
∴ P(B) = 5p = \(\frac{10}{13}\),
∴ P(G) = 3p = \(\frac{3}{13}\)

2.4 Argument And Persuasion

Argument is that form of writing the main purpose of which is to persuade your readers (or listeners) to adopt a certain attitude, point of view, or course of action.

Read the following views, expressed by six different speakers, on the importance of English in India, in a debate in Femina.

a. Years ago the sun did not set on the British Empire, but the sons and daughters of India still speak English. ‘Please’ and ‘sorry’ are very much a part of our vocabulary. In most’states higher education is imparted in the English language. The white man’s language still holds the same fascination today as they did a century ago. More Indians are speaking and writing in English than ever before. A separate class of Indo-English writers, acclaimed internationally, exists today. Telephone directories, advertisements, films, music, etc. are in English. Hence, the language has been integrated into our culture.

b. English is an important language in India today. For all important business transactions, paperwork and documentations is in English (like banking, shares, certificates). The gifts we have received from the British are the postal and telegraph services, railways and the English language. As the industrial revolution first took place in England, most of the mechanical engineering terminology is in English. For instance, there is no Hindi equivalent for the term ‘internal combustion’. It is very important to know English.

c. Knowledge of English language has helped me to communicate not only with my audience abroad but even with Indians of various states. English is an Indian language. If Indian states try and promote their languages, there is nothing wrong in it. But at the same time, English language and literature should not be neglected. It is an interesting language with a rich literature.

d. English is an Indian language. Any Indian who is slightly educated understands English, It is the langauge of science and technology. It connects us with the world. In India, people who know English often dominate non- English speaking Indians. There is no harm in learning and speaking in English, but to follow western culture along with the language is not appropriate.

e. English is one of the languages spoken by Indians. But it is wrong to believe that to achieve or to get a job one must know English. Most people in India feel that to earn their bread they should know English. In Germany, China and Japan people hardly understand English. Among the Indians the ‘mental slavery’ to English still exists.

f. It is a wrong belief that English is an important Indian language. Only two percent of Indian speak it. In fact, it is a language that often leads to complexes. I remember very well when the well-known Russian writer. Rasool Humzatov came to Delhi and narrated his poems, not in English or Russian, but in the regional language. Because he was proud of it. We Indians do not have enough respect and love for our language. Personality, even when I meet people who are well-versed in English, I speak in Hindi.

It is important to dispel the guilt complexes regarding Indian languages, that all of us have.
The main points raised by the speakers are noted below.
(i) English is the language of higher education.
(ii) The language of international communication.
(iii) Only 2% Indians speak English.
(iv) The language of science and technology.
(v) The belief that one can easily get a job or achieve success is not always true.
(vi) People in China, Japan and Germany hardly understand English.
(vii) Self-respecting people respect their mother tongue/dialect.
(viii) People in India need English.
(ix) Early education of a child must be in the mother tongue.
(x) Indian languages including Indian culture get neglected.
(xi) Language of communication inside India.
(xii) Language of business, commerce and advertisement.

Activity 36

We have a number of arguments here, both for and against English. Can you now reach a definite position of your own, after considering both sets of arguments ? Try to produce your own arguments to counter those presented by the speakers : for example, you could argue that English can be replaced by Hindi for the purposes of communication within India, etc. Write a paragraph on any one of these points.

Answer:
One of the main arguments in favour English is that people in India need English. But, in my view, this is not correct. We should know that people in China, Japan and Germany hardly understand English. Nevertheless, they are more prosperous than India. Of course, lately China has felt the importance of English. English is a foreign language and not one of the soil. Only 2% Indians speak English. English has become a medium of education in our colleges and universities.

This is doing an incalculable harm to the proper intellectual growth of students. A fast majority of students fail to understand the lessons imparted through English. The very thinking and understanding of the student is stunted under the weight of an incomprehensible language. The spread of English also hinders the growth of Indian culture. Lastly, though not the least, it can be said that there should be an end to ‘the mental slavery’ that still exists among the Indians.

Activity 37

(i) Given below are some of the views expressed by different speakers on the topic “The Reading habit is dying out” in Femina. Read through each of them.
(ii) Note that some speakers accept the proposition while others reject it. There is one speaker who offers suggestions to improve the reading habits of children. Try to identify the main points in each speech and arrange them under three headings :
(1) in favour of the proposition
(2) against the proposition and
(3) suggestions.
(iii) Add your own points. Be clear about the points you support and those which you do not support.
(iv) Before you start writing on the topic, think of an appropriate beginning. For this, see how the speakers begin their speeches. It will help you in starting your paragraph.

Now read the following speeches.

(a) I agree that reading is a dying habit. A lot has been already written about how television is rapidly stealing a march over reading. The sale of books is diminishing, while the launching of a new television channel has become a regular affair. A lot of children find other ways of passing their leisure hours because they have simply not discovered the wonderland of books and the pleasure it offers. At the age of two or three, they are taught how to read, but as they grow older, they are not taught to use reading for entertainment, information, and knowledge.

Brought up on a diet of textbooks, the child does not get to read anything else. Naturally, when a child finds that the textbooks he/she reads are dull and boring, he/she never feels like reading anything else. There is no addiction more pleasurable than getting hooked on books. Parents should encourage their children to read, but let me point out that most adults don’t read themselves; a cursory glance at the day’s newspaper is all the reading they seem to do. How can they expect their children to develop the habit of reading, when they themselves sit down in front of the TV set in their free time ?

(b) It is definitely true that reading is a dying habit, and one of the major reasons for this decline is the advent of the electronic medium. Even the reading of newspapers has been limited to that headlines and few introductory paragraphs. If one gets the news and can watch a few soap operas for entertainment just by pressing a few buttons, why should anyone then take the trouble of reading? But that’s very sad for we’re losing the very flavor of life.

Just sitting like robots in front of a box that gives us information like robots, like listening to it, watching it — these things kill our intellectual faculties. We’ve failed to realize that the lasting impact on the mind can be provided by the written word alone. Reading gives one time to ponder over things and it enriches our vocabulary too.

(c) The habit of reading is increasing day by day. There is a boom in publishing in India, and our sales have doubled in the last few years. Indian authors are creating ripples in the international literary scene. Our company has linked up with Harper Collins and Pan Macmillan, so international books are being made available to Indian readers at a reasonable price.

Access to technology and infrastructure has made things easier for publishers. It has led to innovations in packaging and graphics. Focused designs have made the appearance of books much more attractive. Printing quality too has improved vastly. The reader today has a good variety to choose from.

(d) I don’t totally agree with the statement that reading is a dying habit. As a librarian for nearly 27 years, I’ve seen students and research scholars. I feel that my reading habit has changed a lot. Students prefer to read magazines and newspapers rather than books. Earlier, during the summer vacations, many students did come to the library for general reading.

today, they have various other options like listening to music and watching television programs. But the library is never empty. Light reading may have declined, but academic reading related to assignments, references, and research, has not.

(e) I don’t think that reading is a dying habit – but that parents and teachers have to play a very important role in inculcating this habit, for they are the role models for children. Since the child has more grasping power than an adult, it is the right age to develop this habit. It is important for parents to spend quality time with their children, to read aloud to children, to listen to what they’ve to say, and answer their questions.

CHSE Odisha Class 11 English Writing Argument or Persuasion

For the proposition Against the proposition
(i) Television has adversely affected reading (i) Students are not being encouraged to read
(ii) Children pass leisure hours in other ways than reading. (ii) Reading leaves a lasting impression on the mind and enriches one’s vocabulary.
(iii) Dull text books discourage the reading habit. (iii) Habit of reading is incresasing and sale of books proves this.
(iv) Adults don’t read them selves and thus are not good role models. (iv) Books of varied kinds are being read now.
(v) Reading materials are prohibitive in costs. (v) Parents should spend. their time with children; reading is not a dying habit.
(vi) Light reading has declined but not academic reading.

The Reading is a dying habit:
Most people believe that the reading habit is dying out and they are right about it. Even a cursory survey among students reveals that they spend more time watching television than reading books, except during examinations. Besides, children spend their leisure in many other ways rather than reading books. In addition to this, today’s textbooks are so dull and boring and studying has been made such a burden that children or students don’t have the motivation to read books.

Moreover, adults themselves do not read many books. They don’t serve as role models, instead they too spend more time on the T.V. Last but not the least, the cost of books have today become prohibitive. On an average, a book costs seventy-five to hundred rupees. It is all these factors that have made reading a dying habit. It is right that students are not being encouraged to read, that reading is something worthwhile, but suggestion that since sale of books have increased and therefore reading has increased is to miss the point.

A comparative study of sales of electronic consumer items and that of books reveal that the sale of electronic goods is twice as much as those of books. Moreover, those engaged in academic reading are a very negligible minority and they can’t be counted with those who read for pleasure. Similarly the contention that varied books are 1 being read does not prove that there are many readers. This attests the fact that today interests of people have become diversified and therefore to cater to their needs various kinds of books are being published and sold.

For example, a century back we had no books on computers but today there isn’t any library or bookshop which does not possess books on computers. Thus, we can safely conclude that reading is a dying habit. The television is now reining supreme over the minds. The T.V. is ubiquitous even in the smallest of homes while illiteracy is rampant in a place like India.

e. Is against Indian democratic traditions.

The presidential form of government is more suitable for our country than the parliamentary form.

It is just about 50 years since our country has been an independent nation. And numerous problems have been plaguing our nation. This has set people thinking in some quarters that there is a need to change our form of government. That would be like throwing the baby with the bathwater. The nation is just a baby with a particular structure and it need not be changed just because it has not grown and matured. In short, the parliamentary form of government does not need to go.

It is argued that the presidential form of government will ensure a strong centre, curb divisive tendencies, quicken changes in economic, social and political spheres, avoid wasteful expenditure on elections and party politics, simplify decision making and lead to greater discipline. There is no denying this fact. A presidential system does quickly bring about such changes but in the long run, as history has time and again shown, proves counter-productive and disastrous.

The rules of Mussolini, Napoleon, Stalin and Hitler are all outstanding examples of this trend. The presidential form of government makes the state larger than the individual, makes personal freedom a dream and gradually stamps out human rights. Finally, it leads to totalitarianism and dictatorship. The fear of facing a 1984-like scenario is ever alive in a presidential form of government. Oligarchy, plutocracy, stratocracy, autocracy and despotism are ominous realities in a presidential form of government.

History amply records this truth. The KGB and the communist party in USSR, the Nazi Party and the storm troppers in Germany are good examples of what happens when power is concentrated in the hands of a few or in one man’s hand. Moreover, a presidential form of government will gradually crush minority talent and minority culture and impose a cultural homogeneity. This would be disastrous in a multiracial, multicultural, multi-lingual, pluralistic society like India.

Its ethos would take the beating and its beauty will be lost. india has existed for ages as a pluralistic society whose greatness has been its power to assimilate and unite in its fold diverse cultures and religions. Tolerance and non-violence have been its mainstay and to abandon them would mean going against the grain of our character as a nation. Such a forced change would prove disastrous for the nation. Hence the parliamentary form of government with its respect for individual right, and its inclination towards unity in diversity, should be given the thumbs up.

In several cities, television has come to nearly all homes. Some people welcome this while others find it a bad influence and an expensive addition to the drawing-room. Some believe it creates problems – indiscipline, loss of sleep, reduced attention to homework, the danger of bad movies as bad models. Others consider it a good ‘teacher’ – brings vividly a lot of new information, helps farmers, makes stories interesting, provides both entertainment and instruction, saves money spent on bad/indifferent films, food at restaurants, etc., keeps the family together at home. A television company has organised an “essay competition” on the subject ‘Television, your new friend’. At the same time, the ‘Society of Cinema-goers’ has invited essays criticising television. Write on each topic, presenting your views on television, and its uses/abuses.

(ii) Provides both entertainment and instruction (ii) Reduces attention towards homework
(iii) Leads to the togetherness of the family members (iii) Bad movies act as bad models
(iv) Saves money spent on food at restaurants (iv) An expensive addition to the drawing room

Answer:
Television: its uses and abuses :
Television has truly made the world a global village. Its all-encompassing reach to the remote comers of the globe has made omnipresent medium. Moreover, the fact that it is an audio-visual medium, makes it all the more effective as well as alluring. Thus, it could be put to a wide variety of use. But it is more abused than used. In a developing country like India, television has become the medium by which literacy is spread all over the nation.

Students tune into educative programmes like the country-wide classrooms of the University Grants Commission and Krishi Darshan Programmes cater to the needs of farmers. Similarly programmes on family planning, health awareness, AIDS, nutrition baby care are beamed across the country. Forecasting of weather and climate helps fishermen, farmers and all kinds of people to plan out their future course of action. Storm warning, earthquake warnings and flood warmings have had a greater impact because of visual and graphic details of facts.

Above all, television has become the supreme medium of infotainment. Watching the news or watching a soap opera, a cookery special or a sports channel, a movie or an engaging group discussion, a sermon or a song, the television has it all, controlling and dispersing knowledge all over the world. And yet unconsciously the television is ruling us, stealing our time and making morons out of us.

A couch potato is no more a rarity. A great thinker enumerates the abuses of television as follows. First, television makes people emotionally insensitive. The images of sex and violence that are projected on the screen gradually drive out all human feeling from us and renders us indifferent to such incidents in real life. We accept them as normal. A murder, a rape, a dead body no more shocks us as it did earlier generations. We are gradually being denuded of humane feeling.

Second, television makes viewers morally uncritical and impairs their sense of judgement. With a book, one reads and then ponders over what it has stated but the television gradually impairs this sense of evaluation in us. It hits us so powerfully and forcefully that it bypasses our head and rules our heart. Third, television destroys our ability to concentrate for long on anything. Kids who are brought up on fast moving scenes and cartoon characters thus do not find their teachers exciting, their books seen dull and boring.

Quickfix solutions, capsule presentations, ready-made notes, fast food are the order of the day and television is one great factor in enhancing the pace of life and thereby reducing concentration spans of people. Fourth, television sets up such role models and projects such lifestyles which young people follow with zeal. They are led to believe that all that life is about is having girl-friends, wealth, fame and power. Finally, T.V. is creating dislocations in centres of authority.

Most often a person becomes authoritative because he or she is well- known. Thus a cricket star or a hero tells you to keep away from AIDS and has your attention no matter what he does in his personal life. Thus, his voice is powerful while that of a celibate priest’s is not. As a result there is total psychological, moral and academic confusion in our culture. T.V. is not bad just as money is not bad. It’s the way one uses it that matters. Let the T.V. be our servant and not our master.

Activity 40

Here are a few more topics for argumentative writing. Prepare outlines and write on each topic.
i. Men and women should/should not be paid equal wages for equal work.
ii. Prohibition will save the country from destruction/Prohibition goes against individual freedom. (Prohibition-disallowing by law the making and sale of alcoholic drinks.)
iii. Cricket commentaries are a national evil./ Cricket commentaries provide entertainment and education.
iv. History breeds narrow-mindedness. It should not be taught in schools/colleges.
v. Driving licenses should not be issued to students in schools/colleges.
vi. Girls should not marry before they are twenty, boys before they are twenty-five.
vii. College education must be made free.

Answer:
(i) Men and women should be paid equal wages for equal work.
For:
(a) Equal pay for equal work ensured in the Indian Constitution.
(b) Women do not work lesser than men/women do equally good work as men.
(c) It is the quality of work which matters and not who did it/wages are given for task completed, and not because someone did the task.
(d) Pay hike and promotions are made on grounds of merit and not on basis of gender.

Against:
(a) Women are less intelligent than men.
(b) Women work less than men.
(c) Women cannot do certain kinds of work because they are not physically fit to do it.

Gender differences have curbed the rights of women in a patriarchal and male dominated society. As a result, in some quarters it is still held that women should not be given equal wages as men. This kind of primitive thinking is a result of male chauvinism and is not justified by facts at hand. It has nothing to do with the question of women receiving equal wages as men. Patriarchal society has always held women as inferior to men. As a result, women were thought to be less intelligent than men.

This argument was thus put forth in favour of giving lesser wages to women. The contention is however not borne out by facts. Women have proved themselves the equals of men in almost all professions and spheres of life whether in science and techlology or in the humanities and social science. As more and more opportunities are being given to them women are proving themselves equal for men in every sphere of life.

Admittedly they are biologically made less strong than men but now-a-days work requires more brain and, therefore, the question of equal pay for equal work arises in the context of what work woman is doing and not what she is not. Besides, women Boxers, wrestlers, athletes, weightlifters. Marathoners etc. have proved that they too can do things like men. However, a strong case can be made for the question of equal pay for equal work for women.

First of all, just as equal opportunity for all is enshrined in our Constitution, so also equal pay for equal work is enshrined in our Constitution. A just and fair society will always provide equal pay for equal work for that is the universal law of natural justice. Considerations of caste, creed, race and sex should never come in way of a person’s wages. Secondly, it is another natural axiom that the meritorious be rewarded. If the woman is equally qualified as man, if she does work equal to man, then she deserves a wage equal to it, as men do.

Pay hike and promotions are decided on merits of individuals and not on considerations of caste and creed or sex. Finally, it may be argued that women in many ways are better than men. They are more sincere, committed, honest, responsible and hard-working than men. Case studies of working men and women has proved this. Thus, women deserve equal pay for equal work because they are in no way inferior to men in their qualifications and in their work.

(ii) Prohibition will save the country from destruction / prohibition goes against individual freedom.
For:
(1) Drinkers are bread winners, drinking therefore denudes the bread supply.
(2) Drinkers are physically violent; they indulge in wife beating and also a general nusiance.
(3) Drinking leads to hazardous health problems, the cost of which has to be borne buy family / govt.

Against:
(1) Prohibition curbs freedom of an individual.
(2) Prohibition breeds illegal trade in liquour.
(3) Prohibition results in loss of revenue to state.

Prohibition will save the country:
Drinking and smoking are two-sides of the same coin. They are equally dangerous and hazardous not only for the individual but also for the nation as well. Therefore, it is necessary to implement and ensure prohibition, for this alone can save the country from destruction. The opponents of prohibition are of the view of that it curbs freedom of the individual. They are right but of course individual freedom has always been curbed by social limitations to ensure that every other individual enjoys his or her liberty.

A man has the right to walk on the road as long as he does not infringe anybody else’s right to walk on the road. If drinking results in social disharmony, then it must be prohibited. A doctor prescribes a bitter pill to heal a person in spite of the protests of an individual. A whole individual can be a useful citizen. Secondly, anti-prohibitionists talk of the breeding of illegal trade in liquor.

True indeed: prohibition breeds an illegal trade in sale of liquor and the very purpose of prohibition is thereby defeated. But illegal trade can be prevented, an alert police, a cooperative public can detect and stop this trade. This has been proved earlier in Andhra Pradesh where women enforced prohibition and curbed illegal trade. Finally, there is the loss of revenue to the state. This too is true. But it can be argued that the cost of having host of diseased drinkers is higher than that of loss on revenue due to prohibition.

It is fallaciously thought that the cost of treating a man with drinking related health hazards is borne by families of those individuals but the national loss in this context is not taken into account. Moreover, less corruption and generation of revenues in other trades can nullify the loss accruing from prohibition. Non-prohibition on the other hand, has high costs in terms of familial, societal and national loss.

Consumption of country liquor by males who are bread winners in lower income groups have left families bereft of the basic needs of food, shelter and clothing. Broken families, loss of childhood, denial of education and health are the result. The social costs in terms of crime, prostitution, child labour, drug addiction, and a host of other problems emerging from such households, are immense.

Moreover, drinkers gradually lose self-esteem, self-confidence and slowly lose skills. They become irresponsible and unfit for work. This happens even among people of higher income group. Their erratic behaviour, tendency to shimk from duty and going on unauthorised leave hurts sectors in which they work thereby adding to the national loss. Finally, it may be reiterated that the cost of rehabilitating a person with drink- related health hazards is exorbitant.

Whether it is the government that finances this, the company or the individual, all of them result in a national loss. On the other hand, the money saved by individuals on enforcement of prohibition results in per capita gain though it may not accrue to the revenue of the state. Prohibition is therefore a better option than the freedom to drink. For prosperity of the family leads to prosperity of the nation.

(iii) Cricket commentaries are a national evil / Cricket commentaries provide entertainment and education.
For:
– Is a waste of time
– A hobby of the leisure class
– Take too much air time and T.V. time.
– Does not benefit the state or nation.
– Denies equal weight to other sports.

Against:
– Commentary is an art.
– Commentary provides entertainment and education.
– Commentaries provide job and earn revenue.

The very mention of cricket commentaries as a national evil gives rise to passions because the game of cricket is the favourite of a large majority of the upper and middle classes of people. Nevertheless a reasoned analysis of its pros and cons reveals that cricket as well as its commentary is a national evil. First of all cricket commentaries involve a colossal waste of time. During a cricket match, offices are deserted and so are schools and colleges.

People in factories and business establishments slow down work and sometimes even stop working. Moreover, a game of cricket takes a lot of time. A test match spans three to five days while the one day game consumes 8 hours. An avid fan of cricket who listens to its commentary pays little attention to work because the match is held mostly during office hours, school and college hours from 9.00 a.m. to 4.00 p.m.

Time is money and therefore the damage to the economy during a cricket match is irreversible. On an average if a man watches cricket for 4 hrs. a day for 60 days, there is a waste of 24 hrs or a total of 10 days in a year. If the number of those watching or listening to commentaries is even a minimum of 2 million then there is an astounding waste of 20 million days.

The corresponding loss to the economy is therefore colossal. Besides this, cricket commentaries occupy too much of air space as well as as visual space on the T.V. The radio and the television could be used to broadcast other | programmes of social interest during this time. An even greater lacunae is the unequal media coverage that other sports receive. The priority that is given to cricket by the media and T.V. networks does not encourage sportspersons of other games.

While sponsorers are available to- support cricket matches there are very few sponsorers to support the broadcasting of other sports. Further, the revenue generated from commentaries on cricket matches is mostly 1 deposited in the offices of the T.V. Network which has bought the rights to brodcast the match. Revenue to the state in this context is paltry. Opponents of this view that commentaries are a national evil hold that they are educative and entertaining.

But it may be reasonably shown that their educative value is minimal and marginal. As for entertainment that is a very transitory form Of entertainment. The same can be said of its value as an art. It is art of transitory value and does not have any permanent or lasting effect. As for the contention that it provides jobs, it can be said that employment opportunities as commentators are very minimal, limited only to a few individuals and that it is not to be taken as a profession. Thus after weighing the pros and cons it may be emphatically said that cricket commentaries are a national evil.

(iv) History breeds narrow-mindedness. It should not be taught in schools/colleges.
For:
(1) History breeds crude nationalist.
(2) It is full of crimes.
(3) It provides a confused heap of facts.
(4) It records popular beliefs.

Against:
(1) History is interesting and useful.
(2) It helps us to escape the burdens of life.
(3) It is a sound teacher.
(4) It provides us moral inspiration.
(5) It widens our intellectual outlook.

History generated crude nationalism among the students. It records the glory and achievements of some countries and the failures of others. Germany under Hitler was a case in a point. The students who read it learn nothing. History is a record of war and blood-shed. If we scan the pages of history, we learn a lot about many bloody battles fought among different nations. History takes us to a world where lies a confused heap of facts. It is difficult to understand and analyse them. These facts lack colour.

Above all, it acquaints us with some popular beliefs. There is nothing innovative about them. All these facts mentioned above adversely affect the minds of the people. Therefore, history should not be taught in schools/colleges. We should see the bright side of history. It launches man on a thrilling adventure of a journey to the past. It awakens in him the racial memories that he slumbering in the depths of time. The study of history strengthens one’s faith, however, wavering, in the ultimate decency of things.

History must not be read as a collection of dry and old facts and dates, but as living representation of the past which has a significance for the present. The study of history is interesting, useful and amusing. It helps us to escape the burdens of life. Moreover, history is a sound teacher. The records of the past interpreted in practical by noble men and women, supply moral tonic which must be administered to each generation. Study of this subject widens our outlook. Besides, history makes our intellectual horizon touch new heights. It also sensitizes our minds. Therefore, history should be taught in schools and colleges.

(v) Driving licenses should not be issued to students in schools/colleges.
For:
(1) Driving licenses make the students wayward.
(2) They become law-breakers.
(3) They live in a world of fancy.

Against:
(1) Issuing driving licences to school/college makes them responsible.
(2) They save their time.
(3) They become law-abiding.

Issuing driving licenses make school/college students carefree. They move freely in their bikes/four-wheelers without caring anybody. They become liberty drunk. They never feel the importance of why they have been issued driving licenses. They make use of their vehicles for a constructive purpose. They are young. In the full flush of their youth, they drive recklessly, flouting the traffic rules.

Sometimes they meet with accidents. Some die premature deaths, some escape with a miracle and others suffer fractures. These students find themselves cut off from the outside world when they drive their bikes or cars. On the other hand, we must not be blind to the other side of these facts. School/college students should be issued driving licenses, because they are mature. Fear of parents and accidents makes them responsible. They do not want to waste the latter’s money by misusing driving licenses.

They drive their vehicles very carefully. Time is precious. They save it as a result of using bikes or cars. These students become law- abiding. They are alive to the traffic rules. They understand why they have been given bikes/four wheelers by their parents. In view of these facts, driving licenses should be issued to school/college students.

CHSE Odisha Class 11 English Writing Argument or Persuasion

(vi) Girls should not marry before they are twenty, boys before they are twenty- five.
For:
(1) Girls become highly educated.
(2) They get a chance to fulfil their dreams. .
(3) They enjoy empowerment.
(4) They become independent and are free from the drudgery of household work.
(5) They become ideal mothers and wife.
(6) Boys are no different.
(7) They want higher education.
(8) They become independent.

Against:
(1) They should be educated.
(2) Marriage before 20 makes them typical house-wives.
(3) They are immature to understand the ways of the world.
(4) They go astray.
(5) They are deprived of enjoying impowerment.
(6) Boys cannot be highly educated.
(7) They cannot be independent to the core.

Girls should be highly educated in word and spirit. Very few girls continue their studies after their marriage. They try their best to fulfil their dreams and achieve then- goals. Today we see many a woman enjoy empowerment. They have become high- profile entrepreneurs, bureaucrats and academicians. They are now successful political leaders. They brim with confidence. They become independent by earning their livelihood. Educated wives get a respite from the monotany of their household works.

Education makes them conscious of their duties to their husbands and children. They never become a burden on society. Boys are no different from the girls. A certain age is indispensable for building their career, but marriage before 25 puts bars in fulfilling the dreams, hopes and aspiration. Failures to achieve their goals drive them to a state of frustration. As a result of higher education, they earn handsome income and become assets to their families.

On the other hand, if the girls marry before twenty, they cannot enjoy the things they want. They become neither highly educated nor enjoy real empowerment. They become typical house-wives and don’t get a chance to experience what is happening in the external world. Frustration grips them. They don’t understand the language of independence. They often go astray and as a result, bring disgrace to society. Boys suffer the same fate.

Their marriage before twenty-five seldom allow them to go for higher education according to their will. They soothe with frustration for not achieving their goals. They fail to rise to the expectations of their parents. They are shorn of confidence. They can’t be fiercely independent. Therefore, girls should not marry before they are twenty, boys before they are twenty-four.

CHSE Odisha Class 11 English Writing Argument or Persuasion

(vii) College education must be made free.
For:
(1) Scope for higher education, irrespective of caste, creed or colour.
(2) It makes everyone confident.
(3) It leads to independent among the students.
(4) It provides broader exposure to the outside world.

Against:
(1) Ordinary students have no value.
(2) Free college education creates indiscipline.
(3) Wastage of public money.
(4) There is no room for further academic development, there is no much fund for research.

Free college education provides a scope for higher education for all sorts of students, irrespective of caste, creed and colour. They all feel a state of what higher education is. This makes them brim with confidence. Some of the poor students get a chance to dream big and are determined to achieve someting in life. College education makes them independent, because, they get a chance to earn their livelihood.

They are now exposed to the happenings of the external world. As a result, they can contribute to the well-being of their country and fellow-beings. On the other hand, the issue has a darker side. Free college education encourages many ordinary students to sit in their classes. They should have been given vocational education. Instead of reading sincerely, they create indiscipline in the college and as a result, spoil the academic environment.

Besides, free college education costs our public exchequer beyond imagination. The common tax-payer’s money is injudiciously spent. Academic development suffers a serious jolt as a result of paucity of finance. Research work lags far behind. In view of these facts, college education should not be free.

Develop paragraphs of your own, using the following plans. The given topic should form part of the opening sentence.
(a) Topic: There were several things I liked (disliked) about my high school.
Sentence 1: Topic sentence
Sentences 2, 3, 4, 5: The things I liked (disliked)
Sentence 6: Conclusion

(b) Topic: It is easier for someone to express himself in speech than in writing.

It is easier for someone to express himself in speech than in writing.

Answer:
(a) There were several things I liked in my high school. Firstly, we had good teachers who not only taught us well but were also very friendly with us. Secondly, we were never burdened with homework. Instead, we were asked to read what was taught in the class at home. Thirdly, there were a lot of extra-curricular activities which helped in developing our personality. Finally, we had an Old Boys Association which helped us keep in touch with our classmates and to know about the development of our school. Thus, my high school was really unique in many ways.

(b) Is it easier for someone to express himself in speech than in writing? Or is writing easier than speech? Linguists are divided in their views. Some say that speech is easier than writing because one learns to speak spontaneously without having to attend school. They also argue that speech takes less time to learn than writing. Others, however, dispute these views.

They contend that writing is easier than speech because it involves graphic images which the child can easily learn even before imitating speech. They also are of opinion that writing is accessible to speech-disadvantaged children and therefore, more universal. Thus, linguists are equally divided over the question of which is easier, speech or writing.

Activity 32

Write a paragraph on each of the following topics, using Chesterton’s model at page 39.
(a) Types of students
(b) Types of teachers
(c) Kinds of books we read
(d) Kinds of friends

Answer:
(a) Types of students :
Roughly speaking, there are three kinds of students in our college. The first may be called bookworms. They can always be seen pouring over books in the library when they travel by bus while having food and so on. This kind has no interest in games and most often they love to be indoors rather than play outside. The second sort may be called truants. These students take pleasure in not attending classes. They bunk college, go to films, play cricket and create a nuisance on the campus.

To them, we owe all the strikes and indiscipline in the college. The third kind is called Casanova’s. You can see them talking in hushed whispers with girls under a tree, in the corridors, accompanying them to the bus stop, or shadowing others who are not yet in their hold. The studies are secondary and they end up as unemployed youth who dream of their golden day in college.

(b) Types of teachers :
There are different types of teachers. Firstly, there are teachers who are dedicated to the core. They inspire their students to reach newer heights in the future. Their devotion to teaching is matchless. Secondly, there are teachers who just teach students for the sake of teaching. They are never serious about it. They lack dedication to their profession. Thirdly, there are those who pretend to be ideal teachers. They are dull. They always aim at earning money by paying lip service to their profession. These teachers bring disgrace to society.

(c) Kinds of books we read :
Books are of many types but they can be generally divided into good and bad. Good books are man’s most important teachers. They instruct and entertain, make men wise and ignorant, men of knowledge. Bad books, on the other hand, waste men’s time and introduce evil thoughts into their minds. They neither enlighten the mind nor broaden the imagination in the right direction. Thus good books ought always to be chosen over bad ones.

(d) Kinds of friends :
We have friends of several kinds. First, there is gossip. He can never keep our secrets and always lets us down by telling everything about us to others. Second, there is the coward. He is seldom able to stand on his own feet but that is not any danger. Keep him in the team for any enterprise and he’ll take off whenever he smells any danger to himself. Third, there is the flatterer. He always sings your praises and never tells you the truth. He is neither dependable nor trustworthy. He stays with one as long as he profits from his company and then he changes loyalty. Fourth, there is the slanderer.

This kind of friend feigns friendship but behind your back, he talks ill of you. Then there is the follower. This kind rarely takes his own initiative in doing anything for you. He’s a good supporter, a loyal disciple but you can’t hand him any responsibility and sit quietly. He needs nudging and guiding. There’s yet another kind called the parasite. He feeds on you, eats of you, borrows your notes, your money, your cycle, etc. He is always dependable. Finally, there is the one and only true friend. He is rare to find. But this is the kind of friend who is dependable, responsible, and trustworthy.

2. Write a short paragraph beginning with the sentence: “I had a very happy childhood.”
3. Write separate paragraphs from the point of view of the taxi driver and the truck driver, using the following outline. An accident between a truck and a taxi – an old man was killed – a buffalo was seriously injured – a policeman arrived on the scene – a doctor drove the dead body to the hospital.
4. Write a paragraph to be included in a letter to a pen-friend telling him/her how you celebrate Diwali.

Answer:
(1) Refugee is not worth watching. Its story is a stock one: Laila-Majnu, Romeo-Juliet like and perhaps borrowed from Daruwalla’s “Love in the Salt Desert.” There is no life in Abhishek Bacchan’s acting. As for action, there is not much that it has to boast off. Walking like a shepherd with a staff in his hand and a band around his head. Bacchan evokes pity rather than empathy, he does not inspire and he does not display much emotion, seems so wooden. Besides, photography, music, and choreography aren’t great either. In short, I’m afraid I didn’t like the film at all and wouldn’t recommend it to anyone.

(2) I had a very happy childhood. Father, Mother, Grandpa, and Grandma, all of us lived together. Every morning, Grandma would play with me and tell me tales. In the evening Grandpa would take me on walks and in the night I used to huddle in my mother’s lap and sleep. Those days were wonderful. It was all play and no work, no worries, no fears, only love. And every summer we went off to Puri to frolic in the sun and sand, I wasn’t afraid of the sea. Daddy put me on his shoulders and walked into the sea. The smell of the surf and the thundering of the waves excited me then as it excites me now. Truly I can never forget the joys of my childhood days.

(3) The Truck-driver’s point of view: It was almost noon as I carried a truckload of bricks to be delivered at the Institute of Physics. I was on N.H.5 and had already neared Acharya Vihar Square. I was to take a right turn at the square to get into the road leading to Sainik School. Traffic was thin and a buffalo was standing right in the turn and urinating. A taxi was coming from the Sainik School road. I put on the dippers indicating a left turn. I slowed down as I had to avoid the buffalo.

Suddenly, the taxi emerged, flashing its lights. I had already taken the turn while the taxi was speeding straight ahead. I applied the brakes but the vehicle did not halt because of the load. Instead, it careened past the taxi, hit an old man standing serenely and rammed into the ditch beside the N.H.5. My head hit the steering wheel and I became unconscious. When I woke up I was in the capital hospital. The Taxi driver’s point of view: I was returning from Sainik School after dropping a fare.

It was noon and I was supposed to pick up my little children from the convent school. I should have been there by 11.30 a.m. but it was already half an hour behind. Hence I was rushing with thoughts of my children waiting hungrily at school. As I was approaching Acharya Vihar Square, I saw a truck coming toward me. It was turning into the road. I was in a hurry. I did not want to wait till the truck had turned and so did not slow down my speed.

Instead, I flashed my headlights requesting priority of way but the adamant truck driver did not heed to my signal, it was turning. I applied the brakes but it was too late, I rammed into- a buffalo, swerved sharply to the right, grazed past the rear of the truck’s body, and then hit a telephone pole against which the car stopped. Fortunately, I escaped unhurt with only minor pain in my back. But then my problems were, not over. A policeman arrived from nowhere, accosted me, and asked me to get out of the car.

Meanwhile, people who were crowded around informed us that an old man had fallen down unconscious. There was a doctor among them and he suggested that we take him to the hospital. As the old man was brought to my taxi, the doctor noted that he had already died. However, I requested the doctor to keep quiet and immediately drove to the hospital with the dead body. I was lucky not to have been manhandled by people. But I must say it is all the truck driver’s fault. I did not kill the old man.

(4) Paragraph included in the letter

121, Kharavel Nagar,
Bhubaneswar
20 August 20

Dear Joseph,
Greeting from India!
I received your letter and your picture postcard at the same time. I will cherish the card for a long time to come. The picture of the Millennium Dome is crystal clear. It looks very beautiful. Well, you had written to me about how everyone in England celebrates Guy Fawkes day. You did have a lot of fun, really. I could see that from your letter. Do you know, here, back in India we too celebrate something similar to Guy Fawkes? There it commemorates the gunpowder plot but in India, we celebrate a festival called Diwali, the festival of lights.

It symbolizes the victory of good over evil, of light over darkness commemorating the victory of the forces of Shri Rama over the evil forces of Ravana. The festival falls every year in the month of October or November. On that day, we offer Puja to Shri Rama, distribute sweets among friends and neighbors and prepare for the night. We purchase crackers of all sorts and dry them in the sun. We also prepare wick lamps. The lamps and wicks are purchased from the market.

Then oil is poured into the lamps and the wick is set on it. These are then kept in a row on terraces, the boundary wall, on window sills, and everywhere where there is space to keep them. When night falls, these lamps are lit. There must be thousands and thousands of lamps lit in every house, in every street, town, city, district, and state. The house is thus lit like a Christmas tree. It looks beautiful and gay. After this starts the ceremony of lighting fire-crackers. Everyone, from a child to an old man enjoys lighting fire-crackers and bursting them.

This goes on till the last hours of the morning. Often, Diwali is celebrated for two days. Of course, one of these days is only declared a national holiday but then there is no holding back for persons who enjoy Diwali. They take leave and enjoy this festival. This reminds of Guy Fawkes day, isn’t it? Well, do write to me about how you celebrate Christmas. I am eager to hear from you.

With warm regards.
Your loving friend,
Subrat Das.

Now write a passage of 2 or 3 paragraphs on ‘ Working mothers and their children
2. Dear ………………..,
My mother started working seven years ago. My first problem is that I have to keep ringing her up to find things in the house. Second, living with a ten-year-old sister is not as easy as it seems. My younger sister is supposed to take permission from me, but most of the time she doesn’t listen to me. Then I get angry and she rings up my mom who scolds me. Third, I don’t really have much freedom because I have to call my mother to take her permission. She has placed so many restrictions on me that I feel caged in. Fourth, Let me confess that at home I listen to music, watch TV and spend a lot of time with my friends, neglecting my studies. Besides, although my parents never pamper me, they always pamper my sister, my be because she is much younger. Very often I feel neglected when they do that. Lastly, I really wish that my mother or father were at home, especially some months before the boards.
3. Dear…………………,
I think it’s the best way. I don’t think I’d like to see more of my parents at home. I like my free time. At home I read, listen to music, fiddle around with the computer, play badminton and tennis, and even I have started writing because I don’t have any other entertainment. The other definite plus is that 1 get my own privacy, and I have also become more independent, in fact, when my maternal or paternal grandparents come over, then I feel closed in somehow. Since I do my own things, I am pretty confident about everything. But having someone at home is obviously a big advantage. I can never tell myself to study. I often wish my mother were at home to tell me
and help me. Worst of all, 1 waste a lot of my time worrying about security and about meals.

Answer:
Passage 3 throws light on the impact of a working mother on her child. Here the latter likes to be away from its parents. At home, the child enjoys reading, listening to music, playing badminton and tennis, and so on. Lack of any other entertainment makes the child start writing something. The most remarkable thing about it is its own privacy. As a result of its working mother, the child somewhat develops | closeness with its maternal or paternal grandparents. It becomes confident still, the child wishes the mother were at home for help. Worrying about security and about meals takes a lot of its time.

Activity 35

Read the following letters published in an issue of India Today. These letters \ tell us what is wrong with sports in India.

(a) The story on Indian sports (“A Shocking Mess”, August 15) reveals only the tip of the problem. Officialdom and corruption have so spoiled our system that every effort is made to stall an achievement. While sportsmen live like beggars, deprived of quality gear, the managers live like kings.
R. SINGH, NEW DELHI

(b) With neither motivation nor money to galvanize them, it’s no wonder that many players bid goodbye to sports once they get a sound footing elsewhere. It is high time that those who actually know about different sports are appointed at the helm of affairs.
MANI NATRAJAN, CHENNAI

(c) The fact that only 22 of the 46 probables for the hockey team reached the coaching camp shows the lack of commitment of the players. Though official mismanagement can be blamed, the athletes have to accept part of the responsibility.
B.C. PRAKAS, BANGALORE’

(d) If the story on India’s preparation for the Hiroshima Games had been published a year or two ago, it might have had some effect. To an extent, it is this lack of media coverage of sports, other than cricket and tennis, that is also responsible for India’s debacle in various events. MANISH PATHAK, NEW DELHI

(e) The sports mess is hardly surprising. After all, sports are also managed by the bureaucracy and the bigwigs. Like other plans and programs they implement, how could they deviate from their time-honored practice here – plan with fanfare, implement with nonchalance, forget the monitoring, and don’t worry about the results?
K G JAIN, NEW DELHI

CHSE Odisha Class 11 English Writing Exposition

(i) Read the letters again and make a list of the factors that are responsible for the sorry state of Indian sport is in.
(ii) If possible, think of and add your own points to the list.
(iii) Try to write 3 or 4 sentences on each point.
(iv) Write a short paragraph incorporating suggestions for improvement This should ideally conclude your topic. Now write on the topic “The Sorry State of Indian Sports.”

Answer:
Indian sports is in an extremely sorry state today. It is plagued by manifold problems to which there seems no end in sight. Officialdom and corruption have tarnished our sports bodies so much so that, every achievement is stalled. Moreover, while officials grab the limelight and the financial benefits accruing from an event, sportspersons who made it all possible, are handed over the crumbs. With such a state of affairs presiding, our sportsmen do not have any motivation to shine.

Leave alone prize money, they are often not even paid their due. And so, when they get a good job, they bid goodbye to the sports that they so much loved. After all, they also have to earn their livelihood to feed their families. Budding talents too are not spared. Companies would rather have an established player endorse their products than choose a greenhorn. As a result, young sportspersons take the help of their parents, friends, and relatives to hone their skills at meets both at home and abroad.

But when the money they had diminished to a trickle, they turn their back on sports and look for other options. Besides, the media is at fault too. Come cricket or tennis and they run to cover it. What about football, hockey, polo, kabaddi, handball, basketball, Choko, badminton, table tennis, chess, etc? Are they receiving equal coverage? This is a question that is better not asked by the media. They would shrink and then vanish. Then there’s the ubiquitous red-tapism of the bureaucracy and the official bigwigs.

Their plans for the development of sports in the country sound grand, but they are seldom implemented. They go “bang”, and “bang” in speeches but their implementation always ends in a whimper. However, all blame cannot be laid at the doors of others. Sportspersons too are responsible for this state of affairs. They lack commitment and professionalism. A foreign trip is coveted more for the glamour and the sightseeing than as an opportunity to bring home medals.

Most often, groups lack team spirit and this is very obvious in their game. How can these problems be solved? It is easier said than done. Solutions may be suggested but who will implement them? First, perhaps there should be an attitudinal change among the people who run the sports in this country. They should take it seriously as something concurring with national honor and national pride. Secondly, eminent sportspersons should run sports bodies.

Third, sportspersons must be encouraged by monetary rewards, and their achievements recorded and honored by sports bodies as well as the government. Fourth, the government must ensure the sponsorship of budding talents for national and international meets. Fifth, media coverage should be given equally to all sports and finally, sportspersons must be inspired to total commitment and professionalism. If and only when these changes are implemented in India, will the scene of Indian sports change for the better?

E-MAIL

E-mail is a medium that has revolutionized the way in which we communicate with each other. It is relatively now very popular E-mail makes it possible to communicate cheaply and almost instantly with people anywhere in the world – provided they have access to a computer. You can send any type of message, from a single word to a book-length document complete with pictures and sound files. The recipient can respond at once or think carefully before replying. You can communicate just with one person or with a large group, every member of which can participate as much or as little as they wish. E-mails inhabit a shape somewhere between personal meetings, telephones, and letters. Like telephones, they are quick and inexpensive. They are a fairly new technology. The format of e-mail is quite simple, just like the telegram form, but there is no room for capital letters in the former. Write e-mail IDs after TV: and from :

Dear Mr. Pradhan,
As requested by you, vide your letter No. MD/NS/2233 dated 2.2.20 we have carried out a market survey to check the public’s acceptance of the new mosquito repellant which your company plans to manufacture. We conducted an opinion poll covering 1000 families in the coastal districts of Orissa. Forty percent of these families use mosquito repellants, but most of them are unhappy with the existing products in the market. They find the electronic repellants too expensive while the coil-based ones emit too much smoke.

The preference is for an expensive product, preferably one that produces no smoke. Our study suggests there may be a good market for a new repellant, provided these requirements are kept in mind. We recommend that your company should concentrate on manufacturing an improved kind of smoke-free mosquito coil, preferably one that produces a pleasant fragrance.
Yours sincerely,

(i) exactly one head
Solution:
A coin is tossed twice.
∴ S = {HH, HT, TH, TT}, |S| = 4
Let A be the event of getting exactly one head.
∴ A = {HT, TH} ⇒ |A| = 2
∴ P(A) = \(\frac{|\mathrm{A}|}{|\mathrm{S}|}=\frac{2}{4}=\frac{1}{2}\)

(ii) at least one head
Solution:
Let B be the event of getting at least one head.
∴ B = {HT, TH, HH}
∴ |B| = 3
∴ P(B) = \(\frac{|\mathrm{B}|}{|\mathrm{S}|}=\frac{3}{4}\)

(iii) at most one head
Solution:
Let C be the events of getting at most one head
∴ C = {HT, TH, TT} ⇒ |C| = 3
∴ P(C) = \(\frac{|C|}{|S|}=\frac{3}{4}\)

Question 2.
A coin is tossed three times. Find the probability of getting.
Solution:
A coin is tossed three times.
∴ S = {HHH, HTT, HTH, THH, TTH, THT, HHT, TTT}
∴ |S| = 8

(i) all heads
Solution:
Let A be the event of getting all heads.
∴ A = {HHH} ⇒ O(A) = 1
∴ P(A) = \(\frac{|\mathrm{A}|}{|\mathrm{S}|}=\frac{1}{8}\)

(ii) at most 2 heads
Solution:
Let B be the event of getting at most 2 heads.
∴ B = {HTT, HTH, THH, TTH, THT, HHT, TTT} ⇒ |B| = 7
∴ P(B) = \(\frac{|\mathrm{B}|}{|\mathrm{S}|}=\frac{7}{8}\)

(iii) at least 2 heads.
Solution:
Let C be the event of getting at least 2 heads.

∴ S = {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6), (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}
∴ |S| = 36

(i) Sum of points is 10
Solution:
Let A be the event of getting the sum 10.
∴ A = {(4, 6), (5, 5), (6, 4)} ⇒ |A| = 3
∴ P(A) = \(\frac{3}{16}=\frac{1}{12}\)

(ii) sum of points is at least 10
Solution:
Let B be the event of getting the sum at least 10.
∴ B = {(4, 6), (5, 5), (6, 4) (5, 6) (6, 5) (6, 6)} ⇒ |B| = 6
∴ P(B) = \(\frac{|\mathrm{B}|}{|\mathrm{S}|}=\frac{3}{36}=\frac{1}{6}\)

(iii) sum of points is at most 10.
Solution:
Let C be the event of getting the sum 11 or 12.
∴ C = {(5, 6), (6, 5), (6, 6)} ⇒ |C| = 3
The C is the event of getting the sum at most 10.
∴ P(C’) = 1 – P(C’) =  1 – \(\frac{3}{36}=\frac{33}{36}\)

Question 4.
A die rolled twice. Find the probability that the result of the first roll exceeds the result of the second roll by
Solution:
A die rolled twice S = \(\left\{\begin{array}{llllll}
1 & 2 & 3 & 4 & 5 & 6 \\
1 & 2 & 3 & 4 & 5 & 6
\end{array}\right\}\)
∴ |S| = 36

(i) 3
Solution:
Let A be the event of getting the 1st roll exceeds the result of the 2nd roll by 3.
∴  A = {(4, 1), (5, 2), (6, 3)} ⇒ |A| = 3
∴ P(A) = \(\frac{|\mathrm{A}|}{|\mathrm{S}|}=\frac{3}{36}=\frac{1}{12}\)

(ii) at least 3

Let B be the event of getting the 1st roll exceeds the result of the second roll by at least 3.
∴ B = {(4, 1), (5, 2), (6, 3), (5,1), (6, 2), (6, 1)}
∴ P(B) = \(\frac{|\mathrm{B}|}{|\mathrm{S}|}=\frac{6}{36}=\frac{1}{6}\)

(iii) at most 3
Solution:
Let A be the event of getting the 1st roll exceeds the result of the 2nd roll by 4 or 5.
∴ A ={(5, 1), (6, 2), (6, 1)}
P(A’) = 1 – P(A) = 1 – \(\frac{|A|}{|S|}\)
= 1 – \(\frac{3}{36}=\frac{33}{36}=\frac{11}{12}\)

A card is selected from 100 cards numbered 1 to 100. If a card is selected at random, find the probability that the number on the card is
Solution:
A card is selected from 100 cards numbered 1 to 100.
∴ |S| = 100

(i) divisible by 5
Solution:
Let A be the event of getting the card whose number is divisible by 5.
∴ A = {5, 10, 15, 20, ….. 10} ⇒ |A| = 20
∴ P(A) = \(\frac{|\mathrm{A}|}{|\mathrm{S}|}=\frac{20}{100}=\frac{1}{5}\)

(ii) divisible by 2
Solution:
Let B be the event of getting the card whose number is divisible by 2.
∴ B = {2, 4, 6, 8,…., 100} ⇒ |B| = 50
∴ P(B) = \(\frac{|B|}{|S|}=\frac{50}{100}=\frac{1}{2}\)

(iii) divisible by both 2 and 5
Solution:
If a number is divisible by both 2 and 5 then it is divisible by 10. Let A be a such an event.
∴ A ={10, 20, 30,……,100} ⇒ |A| = 10
∴ P(A) = \(\frac{|\mathrm{A}|}{|\mathrm{S}|}=\frac{10}{100}=\frac{1}{10}\)

(iv) divisible by either 2 or 5.
Solution:
Let A be the event of getting the number divisible by 2 and B be the event of getting the number divisible by 5.
∴ A = {2, 4, 6,……… 100}
B = {5, 10, 15, 20, ……, 100}
∴ A ∩ B = {10, 20, 30, ….., 100} ⇒ A ∩ B = 10
∴ P(A ∪ B) = P(A) + P(B) – P(A ∩ B)
= \(\frac{|\mathrm{A}|}{|\mathrm{S}|}+\frac{|\mathrm{B}|}{|\mathrm{S}|}-\frac{|\mathrm{A} \cap \mathrm{B}|}{|\mathrm{S}|}\)
= \(\frac{50}{100}+\frac{20}{100}-\frac{10}{100}=\frac{60}{100}=\frac{3}{5}\)

Eight persons stand in a line at random. What is the probability that two person X and Y don’t stand together?
Solution:
Eight persons stand in a line at random.
∴ |S| = 8!
Let A be the event that two persons X and Y stand together. Considering X and Y as one person, the total number of persons is 7, who can stand in 7 ! × 2 ways.
∴ |A| = 2 × 7 !
∴ P(A) = \(\frac{|\mathrm{A}|}{|\mathrm{S}|}=\frac{2 \times 7 !}{8 !}=\frac{1}{4}\)
∴ P(A’) = 1 – P(A) = 1 – \(\frac{1}{4}=\frac{3}{4}\)

Question 7.
What is the probability that four aces appear together when a pack of 52 cards is shuffled completely?
Solution:
Let A be the event of getting four aces appearing together. Then considering the four aces as one card, the total number of cards is 49, which can be shuffled in 49! × 4! ways.
∴ P(A) = \(\frac{|\mathrm{A}|}{|\mathrm{S}|}=\frac{4 ! \times 49 !}{52 !}\)

Question 8.
If 8 persons are to sit around a table, what is the probability that X and Y don’t sit together?
Solution:
If 8 persons sit in a round table then the number of ways is (8 – 1)!
∴ |S| = (8 – 1)! = 7!
Let A be the event of getting that X and Y sit together. Considering X and Y as one person, the total number of persons is 7, who can be sit in 2 × 6 ! ways.
∴ P(A) = \(\frac{|\mathrm{A}|}{|\mathrm{S}|}=\frac{2 ! \times 6 !}{7 !}=\frac{2}{7}\)
P(A’) = 1 – P(A) = 1 – \(\frac{2}{7}=\frac{5}{7}\)

\end{array}\right),\left(\begin{array}{lll}
1 & 2 & 3 \\
2 & 1 & 3
\end{array}\right)\right\}\)

(i) none of the records goes to the right jacket
Solution:
Let A be the event that none of the records goes to the right jacket.
∴ A = \(\left\{\left(\begin{array}{lll}
1 & 2 & 3 \\
2 & 3 & 1
\end{array}\right),\left(\begin{array}{lll}
1 & 2 & 3 \\
3 & 1 & 2
\end{array}\right)\right\}\)
∴ P(A) = \(\frac{|\mathrm{A}|}{|\mathrm{S}|}=\frac{2}{6}=\frac{1}{3}\)

(ii) just one record goes to the right jacket.
Solution:
Let A be the event that none of the records goes to the right jacket.
∴ A = \(\left\{\left(\begin{array}{lll}
1 & 2 & 3 \\
1 & 3 & 2
\end{array}\right),\left(\begin{array}{lll}
1 & 2 & 3 \\
3 & 2 & 1
\end{array}\right),\left(\begin{array}{lll}
1 & 2 & 3 \\

∴ P(A) = \(\frac{|\mathrm{A}|}{|\mathrm{S}|}=\frac{3}{6}=\frac{1}{2}\)

(iii) just two records go to the right jackets.
Solution:
Let B be the event that just two records goes to the right jackets. When two records goes to the right jackets, then it is obvious that the 3rd jacket must go to the right jacket.
∴ B = Φ
∴ P(B) = 0

(iv) all three of them go to the right jackets.
Solution:
Let C be the event that all 3 of them go to the right jackets.
∴ C = \(\left\{\left(\begin{array}{lll}
1 & 2 & 3 \\

\mathrm{R}_1 & \mathrm{R}_2 & \mathrm{R}_3 & \mathrm{R}_4 \\
\mathrm{~J}_2 & \mathrm{~J}_4 & \mathrm{~J}_1 & \mathrm{~J}_3
\end{array}\right)\)
\(\left(\begin{array}{llll}
\mathrm{R}_1 & \mathrm{R}_2 & \mathrm{R}_3 & \mathrm{R}_4 \\
\mathrm{~J}_2 & \mathrm{~J}_3 & \mathrm{~J}_4 & \mathrm{~J}_1
\end{array}\right)\)
∴ When R1 be put in J2, there are 2 such cases. Similarly when R1 be put in J3 and J4 the number of such cases is 3 each.
∴ The total number of ways in which none of the records goes to the right jackets is 3 × 3 = 9.
∴ Its probability = \(\frac{15}{24}=\frac{5}{8}\)

(ii) at least one record is put in the right jacket.
Solution:
The number of ways in which at least one record goes to the right jacket, i.e. 1, 2, 3 of 4 records goes to the right jacket is 24 – 9 = 15.

P(A’) = 1 – P(A) = 1 – \(\frac{1}{3}=\frac{2}{3}\)

(iii) P(A ∩ Bc)
Solution:
P(A ∩ Bc) = P(A – B) = P(A) – P(A ∩ B)
= \(\frac{1}{3}-\frac{1}{4}=\frac{4-3}{12}=\frac{1}{12}\)

(iv) P(A ∪ Bc)
Solution:
P(A ∪ Bc) = 1 – P(A ∪ Bc)c
= 1 – P(Ac ∪ B) = 1 – P(B – A)
