CHSE Odisha 12th Class Alternative English Solutions Poem 1 Indian Children Speak

Pre-Reading Activity:
Very often we fall to understand each other. This happens especially when we are prejudiced against each other. To understand the other we need to develop a positive attitude. How would you react if you are described as just the opposite of what really you are? What can you do to clear the misunderstanding? Now read the poem below to see how the speaker tries to clear one such misunderstanding of some white people about the Red Indian children.

Questions For Discussion:
Question 1.
When you read the poem, you come across such names as Pansy, Delores, Ramon and Joe Henry. How can you describe them together.
Answer:
They are all Red Indian children.

Question 2.
Throughout the poem the phrase ‘people said’ has been repeated. Who are these people?
Answer:
These people are the white people.

Question 3.
What does moon-coloured dress refer to?
Answer:
It is bright, yellowish-white coloured dress.

Question 4.
Are the Indian children really dumb? Give reasons for your answer.
Answer:
The Indian children are really not dumb. It is because the narrator says, ‘clearly, I hear Delores answer/yes, the sunset is so good,I think God is throwing /Abright show I around the shoulders of the sky.’

Question 5.
Who do you think are rude – the white people or the Indians? Why do you think so?
Answer:
The white people were rude because they say Indian children are heard to reach, they are silent, they are dumb, they have no affection, they don’t seem very bright and they never take other in.

Question 6.
What is the speaker’s attitude towards the Indian children?
Answer:
The speaker is sympathetic and co-operative with the Indian children. His sense of sympathy stands as a sharp contrast with the uncompromising apathy of white men.

Question 7.
How many voices do you hear in this poem? Whose are they?
Answer:
There are three voices – the voice of the speaker the voice of white men and the voice of the Indian children in this poem.

Question 8.
The poem begins with ‘people said’. But towards the end of the poem the speaker says – ‘I have forgotten the idle words that people said’. Does this suggest a transition of mood and attitude in the speaker? Explain
Answer:
This certainly suggests a transition of mood and attitude in the speaker. It is because shedding the age old hackneyed bitter expression of the white man on the Indian children, the speaker switches over to another mood and mind.

Question 9.
What does the speaker convey in the last three lines of the poem?
Answer:
The last three lines are the concluding lines which convey that the speaker has personally parted with the indecent attitude towards the Indian children. He keeps in store in his heart to slip into the heart of Indian Lands and wants for that time to come.

Question 10.
Do you think the Indian children’s view of the world is different from that of the white people’s? How so?
Answer:
The Indian children’s view of the world is certainly different from that of the white people’s. The white people’s view is quite detrimental, command and selfish.

Question 11.
Is the speaker in the poem an American, Indian or a white American? How do you know?
Answer:
The speaker in the poem happens to be an American who makes it explicit in the line of the poem. ‘AndI steeped into the heart ofIndianLand’. This statement proves that the poet is an on-Indian.

Composition:
Question 1.
The speaker in the poem is not one of the ‘Indian children’. When then does the poem bear the title ‘Indian children speak’? Examine the appropriateness of the title of the poem.
Answer:
The title of the poem reads ‘Indian children speak’. The very title is suggestive of the voice of the Indian children although the poet himself is not one of the Indian children. The Indian children are the focus point of the poem. They are the pivotal characters around whom the whole edifice of the poem revolver. The speaker in the poem is not one of the ‘Indian children’. But the poem bears the title ‘Indian children speak’. The speaker is dissociated from the Indian children and makes an impersonal approachonbehalfoftheIndian children whom he likes and wishes to become apart of them He also desires to forget the idle words the people said and wants to treasure the day when the day when the iron doors swung wide so that he would slip into the heart of Indian land. All these speaks volumes of the question in contest.

Question 2.
There is an undercurrent of irony throughout the poem. Discuss how.
Iron refers to _______________________________________
Now discuss how there is an under current of irony in the poem?

Activity – 7:

In many old-fashioned Grammar books, you may find some objection to the use of one-line paragraphs. Are there any one-line paragraphs in this passage? Why does the writer use them? Is he justified in using such small paragraphs?

Answer:
Yes, there are some one-line paragraphs in this passage. They are:

1. Besides its great flexibility, knowledge has other important characteristics that make it fundamentally different from lesser sources of power in tomorrow’s world. (Paragraph – 12)
2. Today in the first changing affluent nations, despite all inequalities of income and wealth, the coming struggle for power will increasingly turn into a struggle over the distribution of and access to knowledge. (Paragraph -12).
   The writer makes use of such one line paragraph in order to put forth his own views in the midst of a general discussion. He is quite justified to have used such a paragraph system.

Activity – 8:

Note-Making:
In the first section of the passage, we came to know that-
1. Force and wealth of knowledge.
2. Knowledge —> power.
3. Force and wealth g knowledge.
That is to say, force and wealth depend on knowledge, is the source of the highest quality power and knowledge is the most important ingredient of force and wealth. Now, make point notes on Sections 2 and 3 using such symbols wherever possible.

Answer:
Weapons and surveillance technologies & knowledge
Knowledge —> computers.
Non-facts and disputed facts a power conflicts in society. False and lies / ‘true’ facts and scientific ‘laws’ —> knowledge.

Activity-9:

Answer the questions as briefly as you can:-
Question (i).
How does Toffler establish that knowledge is the most important ingredient of force and wealth?
Answer:
The military which rests on force uses computerized knowledge. The advanced economy can not for thirty seconds without (knowledge) computers.

Question (ii).
How does he distinguish among ‘data’ information and ‘knowledge’?
Answer:
‘Data’ means more or less connected ‘facts’, ‘information’ refers to data that have been fitted into categories and classification schemes or patterns; ‘knowledge’ means information that has been further refined into more general statements.

Question (iii).
Why is the second section named ‘facts’, ‘lies’, and ‘truth’?
Answer:
Facts, lies, and truth are the things around which the second section has been centered. The whole section is a reflection of most things.

Question (iv).
How is it that knowledge is the most democratic source of power?
Answer:
Knowledge is the key to all kinds of things. It encompasses the means of communication that shapes the message that flows through them. Unlike bullets or budgers, knowledge itself gets used up. The revolutionary characteristics of knowledge that it can be grasped by the weak and poor as well make it the most democratic source of power.

Question (v).
What does Toffler mean by the concept of power-tria? (Paragraph -18)
Answer:
The power tria-patriarch of a family, president of a company, and Prime Minister of a nation wants to control the quantity, quality, and distribution of knowledge within his or her domain.

Question (iv).
Look at the introduction and the conclusion and say briefly, how they relate to the body paragraph of the exports.
Answer:
The introduction starts with knowledge of the part which had never imagined such an explosion of knowledge in the modem world. The conclusion tells that the modem knowledge has reached such a zenith that its provision is not too far. The control of knowledge has become the most important aspect. The introduction and conclusion of the passage are just like prefixes and suffixes ofthe body. The body passage is just an advancement between the introduction and the conclusion.

Power-Shift Summary in English

Summary:

From satellites to submarines, modem weapons are constructed of information-rich electronic components. Today’s fighter plane is a flying computer. Even ‘dumb; computers are manufactured with the help of supersmart computers with electronic chips. The military, to choose a single example uses computerized knowledge – ‘expert systems’ – in missile defense. The Pentagon’s Defence Advanced Research Projects Agency (D ARPA) has set as a long-range goal the design of a system that can make ‘one million logical inferences per second’.

Logic inference, and epistemology – is short, brain work by humans and machine is today’s precondition for military power. It has so become that the advanced economy could not run for thirty seconds without computers. Therefore, knowledge is not only the source of the highest quality power but also the most important ingredient of force and wealth. Put differently knowledge has gone from being an adjunct of money power and muscle power to bringing their very essence.

It is, in feet, the ultimate amplified which is the key to the power shift that lies ahead. There are as many definitions of knowledge as there are people who regard themselves as knowledgeable. Matters grow worse when words like signs, symbols, and imagery are given highly technical meanings. To make things simple and escape from these definitional quicksands, even at the expense of vigor, the term knowledge will be expanded in the pages ahead.

However, besides its great flexibility, knowledge has other important characteristics that make it fundamentally different from the lesser sources of power in tomorrow’s world. Thus force, for all practical concerns, is finite. There is a limit to how much force can be employed before we destroy what we wish to capture to defend knowledge, in principle different and infinitely expandable. Knowledge is also inherently different from both muscle and money because one gun can not be used simultaneously by two people. But by contrast, both ofthe men can use the same knowledge either for or against each other, and in that very process, we may even produce still more knowledge.

Unlike bullets or budgers, knowledge itself does not get used up. This alone tells us that the rules ofthe knowledge power game are sharply different from the precepts relied on by those who use force or money to accomplish their will. In fact, today, in the first changing affluent nations despite of all inequalities of income and wealth the coming struggle for power will increasingly turn into a struggle over the distribution of and access to knowledge. The control of knowledge has become the most important necessity which can save humanity.

Some Samples of Advertisement Summary in English

“What I’m really trying to say is that they treat me like a person. A rather overused phrase, I agree but other business women will know what I mean. If Fm in the restaurant there’s none of that over effusive welcome followed by a table behind a pilar or near the kitchen door. I don’t have to take my briefcase into the bar either, to prove all I want is a drink. When I go to my room, there are some little extra touches that make me feel specially welcome. It’s not simply the softer decor. Lila have thoughtfully provided a hair dryer and make up mirror, things I appreciate away from home.

And they can even come up with an iron or a pair of tights at a moments notice. So, I always stay at Lila Hotel whenever I can. I like their friendly and business-like attitude towards me. As speaking as a woman, you can’t say fairer then that.” Lila Hotels International.

The individual does not respond to any external stimuli like sprinking cold water on the feet and for that matter even painful ones like piercing with a pin tingling a nerve etc.

This insensible state is brought about by some interference in the normal functioning of the brain and the nervous system Unconsciousness when partial is called stupor and when complete is termed as Coma.

On the Education of a Man of Business Summary in English

A man of business should be closely brought up in the habit of reasoning. The study of geometry is hardly better for him. Any university course of study designed for him makes his mind agile and gives a variety of information. This system will make him grow acquainted with many modes of thought with various classes of facts and will enable him to understand men better. His youth time may be well spent by the study of metaphysical nature. A breath and a tone may be given to a man’s mode of thinking. It will afterward be of signal use to him in the business of everyday life. Some works transit from the school to the world.

These are particularly needed in a system of educational studies remote from real life. Such works tend to give the students interest in common things about him which he has scarcely even been called upon to feel They display how imagination and philosophy can be woven into practical wisdom. However, our student is not intended to become a learned man, a man of business not a full man but a ready man He must be taught to arrange and express what he knows, for this purpose let him employ himself in making digests arranging and classifying materials, writing narratives and in deciding upon this conflicting evidence.

All these exercises require a method. A method is developed from rule beginnings. There is hardly any degree of toil for which he would not be compensated by such a result. The student of business should begin soon to cultivate fluency in writing. Fluency does not mean the flow of words, but a habit of expressing his thoughts with accuracy with brevity, and readiness. Moreover, in the style of the man of business, nothing is to be aimed at but plainness and precision.

A close repetition of the same word for the same thing need not be avoided. In literature, however, you are seldom brought to account for misleading people, but in business, you may soon be called upon to pay the penalty for having shunned the word which should exactly have expressed the meaning. A consummate man of business should be able to fix his attention on details and be ready to give every kind of argument a hearing.

This will not encumber him for he must have been practiced beforehand in the exercise of his intellect and there they remain in a shapeless heap, another possessed of method can arrange what he has collected, but such a man by the aid of principles goes further and bulbs with his materials. In feet, in addition to a stout heart, he should have the patient temperament and a vigorous but disciplined imagination and then he will plan boldly and with a large extent of view, execute calmly and not be a stretching act of his hand for things not yet within his grasp. He will let opportunities grow before his eyes until they are ripped to be seized.

He will think steadily over possible failure, in order to provide a remedy or a retreat, there will be the strength of repose about him. He must have a deep sense of responsibility. He must believe in the power and vitality of truth and in all he does or says, should be anxious to express as much truth as possible. His feelings of responsibility and love of truth will almost inevitably endow him with diligence accuracy and discreteness these commonplace required for a good man of business.

Given below are eight paragraphs on an appeal from the WorldWild Life Fund. The title of the passage is ‘Seve the Jungle – Save the World’. The appeal is given in eight sections. Ato H. Arrange the sections in the proper order to get the original passage.

(a) What are the burning reasons that drive men to destroy our monumental inheritance? Man seldom does anything for entirely rational reasons: usually, the less rational his ‘reasons, the more he defends them with short-term economic arguments. That is one of the modem lessons in ecology.

(b) We need the timber, we need the animals for food, pets, and of course for sport: continues the argument. Well, the forests have always been generous in their riches as far as they are able. They are not limitless. They are being exhausted at an ever-increasing speed and the habitats of innumerable other species of both flora and fauna and destroyed as a side effect.

(c) Many of you will know – because you have already contributed to our efforts – that the World Wild Life Fund is currently supporting more than 30 percent of conservation projects in various rainforest areas atone. The funds, ‘save the tiger appear for 4,00,000 raised to a magnificent 5,60,000, and governments responded not only by establishing reserves but also by controlling the trade in skins.

(d) We need the land for people runs the argument. Well, many people already inhabit the tropical forest belt. The native tribes have their own two impact lifestyle, hunting, trapping, and practicing a little cultivation. Perhaps not idyllic, it is nevertheless a lifestyle that does not endanger the forest ecosystem. We stress a little cultivation because, paradoxically, the forest soil is often infertile, and trees and green plants thrive on the comfort of their fallen foliage, which is rapidly broken down and recycled as nutrients. So when the jungle is cleared to plant crops, there is no means to put fertility back into the soil. Many governments spend much time resettling, people in deforested areas as part of so-called forward-looking development projects. But the crop yield is meager and brief. The soil soon makes its point. Erosion and flooding also tend to follow deforestation.

(f) Good husbandry- forest ecology, wisdom in planning less greed, and stupidity could keep man and the delicate rainforest relationship in balance indefinitely. This is our last great store host………… …our last wonderland. (g) Homo Faber, Man Builder has tragically always seen the jungles as something alien and environment to be vanquished, replaced with his own construction. In the past twenty years, the rate of pillage has increased alarmingly and huge tracts of verdant, beautiful forest- an irreplaceable treasure house of living things have given way often, to the wasteland. The evidence is that man will redouble his destructive efforts until the forest system is smashed and the jungle will function no more.

(h) Now we ask you to help us find our biggest ever international project: a two-year appeal to raise 1/2 million. The money will be used to sustain national parks and reserves within the tropical rainforest belt, in countries around the globe. Research, planning, manpower, and equipment all will be bought from the money you are able to give. If we cannot save the forests in their original state and the axe the bulldozer and the greater and lesser bureaucrat with his deadly pen have already seen to that- we must save enough to preserve them living burgeoning ecosystems the most remarkable on earth.

Answer:
1. (c) The so-called jungle of popular…………………….on earth.
2. (b) We need the timber…………………..as a side effect.
3. (f) Good husbandry…………………………last wonderland.
4. (d) We need the land…………….to follow deforestation.

Human Environment Summary in English

Progress should become synonymous with an assault on nature in most countries. The highest mountain in the world was claimed in 1953. Nehru objected to the phrase ‘Conquest of Everest”. Poverty and need are the greatest ‘polluters. The environment cannot be improved in conditions of poverty. Nor can poverty be eradicated without the use of science and technology. The inherent conflict is not between conservation and development but the between environment and the reckless exploitation of man and earth in the name of efficiency.

However, industrial civilization has promoted the concept of efficient man. He whose entire energies are concentrated on producing more in a given unit of time and from a given unit of manpower. Pollution is not a technical problem. The fault lies not in science and technology but in the sense of values of the contemporary world which ignores the rights of others and is forgetful of the longer perspective. The environmental problem of developing countries are not the side effects of excessive industrialization but reflect the inadequacy of development. Warfare is the bane of mankind. It not only kills instantly but also maims and deforms the living and the yet-to-born.

This also poisons the land, making it barren and desolate. The environmental crisis will be after the destiny of our planet. No one amongst us, whatever our status or strength in the circumstance, can remain unaffected. Life is one and the world is one and everything is interrelated The population explosion, poverty, ignorance and diseases, the pollution of our surroundings, and the stockpiling of nuclear weapons and biological and chemical agents of destruction are all parts of a vicious circle. Modem man must bear to re-establish an unbroken link with nature and with life.

The northern part is comparatively cooler than the southern one which due to increased accumulation of temperature will not result in a level rise that will force the plant and animal habitat to shift northwards.

Question (iii)
Why do experts think that the poor will be more affected by global warming?
Answer:
It is because the rich and well-resourced people will be able to adapt to climate change whereas the poor will suffer the worst because they will have to be thrown out of industrial and agricultural setups.

Question (iv)
How will global warming affect India’s water resources?
Answer:
India will be visited by frequent floods and droughts due to erratic rains which result from global warming. Agriculture and industry will be badly affected by forest fires and tropical cyclones will be a regular feature.

Question (v)
What will be the effect of global winning in the polar regions?
Answer:
Permafrost thawing, reduction of sea ice, coastal erosion melting of ice sheets, global ocean circulation, and sea level rise will adversely affect the polar regions.

Section – C

You have already read two texts on our environment, both of the written from the scientists, viewpoint. In this section, you are going to read excerpts from an address by a former Prime Minister of India Mrs. Indira Gandhi. Do you think, there is a difference in her approach to the environmental problem?

Impact of Global Warming Summary in English

A large number of scientists have come to the conclusion that the global mean temperature of the planet is likely to rise in the range of 1.4 to 5.80°C by 2100 in relation to 1990. Preliminary indications as to global warming show that changes in regional climate and extreme weather have already affected many physical and biological systems. Increased frequency of floods and droughts is another cause of global mean temperature. Shrinkage of glaciers, melting of ice sheets, lengthening of the growing season in mid to high altitudes northward shift of plant and animal habitat boundaries, early flowering trees, etc. are some examples of the effect of global warming. Human survival is closely linked to the health of the environment. Economic sectors like industry, insurance, and financial services are also dependent upon environmental conditions. Global warming would produce net economic losses in many developing countries.

Impact On Natural and Human Systems:
The impact of global warming ranges from sea level rise to the destruction of ecological systems Every aspect of society will be affected. Global warming will bring about major changes in water distribution and water resources. Glaciers will shrink while smaller ones will disappear water stress in lower latitudes will increase. Higher evaporation due to higher temperatures will cause greater demand for water for irrigation purposes. Monsoons will be more intense causing greater flooding.

The change in precipitation will have an impact on local agriculture and vegetation. Freshwater fish will migrate poleward. The habitat for cold and cool water fish will be destroyed. It will carve a deep effect on the oceans. A decrease in sea ice cover, changes in water salinity, and alteration of ocean circulation currents can be expected. Flooding and land erosion will increase in the coastal areas. The severity of storms will increase. Human health will be in jeopardy.

Regional Impacts:
Polar regions are highly vulnerable to climate change. Climate change will be more rapid in these areas. An increase in temperature will cause an irreversible impact on ice sheets. Global ocean circulation and sea level rise. Fishery and tourism, are the mainstay of the economics of small island states, and the livelihood of their population will be adversely affected. However, the regional impact will be variable, and so will the capacity of different societies to adopt.

Our Environment Summary in English

We are, at present confronting a lot of environmental problems. Before examining the environmental crisis, a slight analysis of the one we inherited should be made. Imagine that you are an astronaut returning to earth from the Mood of Mars and it would lie a nice experience to have come back to this planet from outer space. Although we are facing certain problems here, we are living unique place quite prolific and profitable. The most astonishing of our planet is the rich diversity of life that exists here. Millions of beautiful and intriguing species populate the earth and help sustain a habitable environment. Organisms like viruses, bacteria, and other tiny forms make-up self-sustaining communities. Dense, moist forests, vast sunny, savannas, and richly colorful coral reefs are here.

Environmental Dilemma:
One of the major environmental dilemmas is the rapid growth of the population. Demographers believe that this unprecedented growth rate will slow in the next century and that the population might eventually drop back below its present size. Others warn that the population will quadruple in a century after its birth rate does not corroborate with the death rate. Food shortages and famines may increase in frequency and severity if population growth soil erosion and nutrient depletion continue at the present rate. The deficit in and contamination of water is another threat. Violent conflicts over control of natural resources may increase if we don’t learn to live within nature’s budget.

Supplies of fossil fuels like oil, coal, and natural gas are diminishing at an early rate. Burning of fossil fuels releases carbon dioxide and may bring about sea level rises and catastrophic climate change. Acids formed in the air as a result of fossil fuel combustion already have caused extensive damage to building materials. Chlorinated compounds such as the chlorofluorocarbons used in refrigeration and air-conditioning, also contribute to global warming as well as damage the Stratospheric ozone that protects us from cancer-causing ultraviolet radiation in sunlight. Destruction of tropical forests, coral reefs, wetlands, and other biologically rich landscapes is causing alarming loss of species and a reduction in biological variety.

Toxic air and water pollutants, along with mountains of solid and hazardous wastes, are becoming overwhelming problems in industrialized countries. The health effects of pollution, toxic, wastes, stress, and other environmental ill-of-modem society have become a greater threat than infectious diseases for us in industrialized countries.

Sign Of Hope:
Steps have already been initiated in North America and Europe in reducing air and water pollution. Population in some countries has stabilized. The incidence ofKfe threatening diseases has been reduced sharply increasing life expectancy. In spite of all this much more is to be done for finding a viable solution to the problems. Being aware of the problems we face is the first step towards finding their situations.

Cause-And-Effect Sequence:
Men have longer bones, narrow pelvis and their bones are arranged differently. So the result is that they walk with astride and climbed stairs more quickly. Similarly, find out from the text the causes that result in the following effects.
(i) Men can lose weight more quickly.
(ii) Men have greater strength.
(iii) Menare less intelligent
(iv) Surgery is riskier for men.
(v) Men can do less exercises then women as they grow older.

Answers:
(i) Men can lose weight more quickly.
Answer:
The higher proportion of muscles to fat makes it easier for men to lose weight.

(ii) Men have greater strength.
Answer:
In fact, men have considerably less fat than women and more lean mass. Forty- one percent of men’s body is muscle compared to thirty- five percent for women, it means that men have more music power. When it comes to strength, almost 90 percent of a man’s weight is strength compared to about 50 percent of a woman’s weight.

(iii) Men are less intelligent.
Answer:
Researchers have found that the children with the highest concentration of lead in r their bodies have the lowest scores on their intelligence tests and that boys score more than girls.

(iv) Surgery is riskier for men.
Answer:
Men cannot manufacture blood as efficiently as women can. Men also need more oxygen because they do not breathe as often as women.

(v) Men can do less exercises then women as they grow older.
Answer:
For all men’s muscularity they do not have the energy reserves women do. They have more start up energy, but the fat fucked away in women’s nooks and crannies provides a rich energy reserve that men lack healthy women on treadmills discovered that over the years the female capacity for exercised exceeds the male capacity.

Some Differences Summary in English

Men cannot manufacture blood as efficiently as women can which makes surgery riskier for men. Men also need more oxygen because they do not breathe as often as women. Men breathe more deeply which exposes them to more risk. When the air gets polluted they inhale more of the pollutants into their lungs. Amore recent and chilling findings in the effect of automobile and truck exhaust fumes on children’s intelligence. The exhaust fumes are the greatest source of lead pollution in cities. Researchers have found that the children with the highest concentration of lead in their bodies have the lowest scores on intelligent tests and that boys score lower than girls.

It is possible that these low-scores are connected to the deeper breathing that is typical of the male. Men’s bones are larger than women’s and are arranged somewhat differently. The feminine walk that evokes so many whistels is a matter of bone structure. Men have broader shoulders and narrower pelvis, women are designed for child bearing, forces her to put more movement into each step she takes with the result that she displays a bit of a jiggle and way as the walks. If a man is thought to be brave because he climbs a ladder to clear out the roof gutters, don’t forget that it is easier for him than for a woman.

The angle which a woman’s thigh is joined to her knees makes climbing awkward for her. However, a man’s skin is thicker than a woman’s and not nearly as soft. The thick prevents the sun’s radiation from getting through which is why men wrinkle less than women do. Women have a thin layer of fat just under the skin and there is a plus to this greater fat reserve. It acts as an invisible for coat to keep a woman warmer in winter. Women also stay cooler in summer. Men’s fat is distributed differently. They do not have that layer of it underneath their skin.

In feet men have less fat than women and more less mass 41% of a man’s muscle is compared to 35% for women which means that men have more muscle power. When it comes to strength, almost 90 percent of a man’s weight is strength compared to about 50 percent of a woman’s weight. For all men’s muscularity they do not have the energy reserves women do. They have more start up energy, but the fat tucked away in women’s nooks and carries provides a rich energy reserve that men look. In exercises, men and women are also different

Questions For Composition

Question 1.
…………………. but by heaven I’ve enjoyed myself. I could not exchange the life I have had with that of any kind in the world”. Make a critical estimate ofStephensin the light of the given statement.
Answer:
The short story’s happy man” is written by William Somerset Maugham, an eminent and outstanding storyteller. He has written more than 100 stories. However, his stories express a realistic portrait of the degenerated society given to selfish pleasure and hedonism with no respect for human values or scruples encompasses a large area of human experience. In this light, Maugham’s story is superb and fantastic. It is really, the most typical story fall is a collection. However, the present story reveals that Stephens may not embody the essentials and philosophy of a happy man in a metaphysical sense, but projects undoubtedly a new vision and perspective.

What we notice is intimist spiritual attainment, but an abandonment of took-for-granted life and relationship in favor of a life of sunshine, color, and mirth. In him is there a quest for freedom and the pursuit of bohemian life. Maugham seems to provide a new pattern and direction to life through his protagonist. Yet the undertone of irony is apparent to the discerning reader. However, Stephens, following the suggestions of the narrator decided to stay in Spain. He went there at last. His wife did not back to Camberwell where she was even more Homely. But he enjoyed his work in Spain. He was very fat and bold. But his eyes twinkled gaily and his fleshy, red face bore an expression of perfect good humor.

The clothes he wore were terribly shabby. He earned just enough money to keep his body and soul together, but he should lead a wonderful life. Poor has he been and poor shall he always be, but by heaven, he has enjoyed himself. He says emphatically that he would not exchange the life he had with that of any king of the world. As a matter of feet, Maugham’s treatment of life through Stephens is most fascinating and heart-touching Maugham is, in fact, a keen observer of human attitude, on the whole, he has tried his level best to depict a full-fledged manner. Therefore, the way he has portrayed Stephens is superb and fantastic.

Question 2.
Critically comment on the title of the story.
Answer:
The short story“The happy man” is undoubtedly the best typical masterpiece of William Somerset Maugham, a prominent and outstanding storyteller of the twentieth century. Maugham is a prolific writer writing novels, short stories, plays, etc. in one. Hismasteryto provides appropriate titles to his writings is really outstanding. He has written more than 100 short stories. All these are repleted with a realistic portrait of the selfish pleasure and hedonism of society. However, the title of the work of art must be apt and suggestive. It should be precise, concise, and condensed.

Its motto should be to communicate reality vehemently. It should be just like a gorgeous, colorful signboard. It also speaks out the contents, of the shop from its very appearance. The titles are expressive of the contents of the work of art. The story, here, tells us about the life of a man who happens to be the happiest. However, Stephens comes to the narrator to know whether it would be better to go to Spain as a doctor. His future was involved in it and the narrator suggested to him that he had to earn just enough money to keep his body and soul together. He, however, decided to go there. But he was married. His wife did not cooperate with him. She never likes Spain and went back to Camberwellwhere she felt homely.

Stephens went alone and lived there happily. He led a wonderful life there. Poorhehadbeen and enjoyed himself like anything. He would not exchange the life he had with that of any kind in the world. The last lines of the story are themselves expressive of the feet that the protagonist of the story “TheHappyMan” has. The title bears the justification for the right caption of the story. As a matter of fact, the title of the story is most appropriate and suggestive. The way Maugham justified Stephens as the happiest man is really superb, alluring, elevating, and excellent.

Notes On The Writer:
William SomersetMaugham(1874-1965) is a prolific writer of the twentieth century having to his credit about 17 novels, 32 plays, more than 100 short stories, two travelogues, and two treatises containing his views of life and literature. Amonghisnovels “OfHumanBondage”. “The Moon and Six Pence” “The Printed VeilCakes and” and ‘The Razor’s Edge” have earned him critical acclaim.

His novels, plays, and short stories give a realistic portrait of a degenerate society, a society given to selfish pleasures and hedonism with no respect for human values or scruples encompassing a larger area of human experience. Most of them depicted the crumbling of the institution of marriage, which has almost become a tightrope around the neck of the spouse’s affair, such indulgences often leading to promiscuity. With deft and dexterous use of irony and satire, his vision grows from a study of the wider spectrum of life to an affirmation of its meaning at the individual level.

The Story:
A careful reading of the story reveals that Stephens may not embody the essentials and philosophy happy man in a metaphysical sense, but projects undoubtedly a new vision and perspective. What we notice is intimist spiritual attainment but an abandonment of taken-for-granted life and relationship in favor of a life of sunshine, color, and mirth. Intimate there is a quest for freedom and the pursuit of bohemian life. Maugham seems to provide a new pattern and direction to life through his protagonist. You have the undertone of irony apparent to the discerning reader.
