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.

Inferring:
You can infer information that is not stated clearly in a text by making a logical guess either from what is on the text, or what you know about the world or both.
(i) What happens during surgery that makes it riskier for men?
Answer:
Men cannot manufacture blood as efficiently as women can. This makes surgery riskier for men. As men breathe deeply they inhale more pollutants that complicates surgery.

(ii) Whose knees are more likely to be hurt by the same activities men’s or women’s?
Answer:
Women’s knees are more likely to the hurt by the same activity.

(iii) Name one part of the body where bad goes when it’s breathed in?
Answer:
Lead goes to brain through blood causing less intelligence.

(iv) Name one advantage a man would have and one advantage a women would have in a hot, sunny country?
Answer:
Men in sunny countries wrinkle less than women do women, stay cooler in summer.

(v) If a man and woman weighed the same at the age of 20, who would be strong at the age of 60?

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

Analytical Outlines:

  • They have more lean mass.
  • 41% of men’s muscle is compared to 35% for women.
  • It indicates that men have more muscle power.
  • Then strength of both is compared.
  • Almost 90 percent of women’s weight is strength.
  • Whereas it is 50% in case of women.
  • Mendo not have the muscular energy reserve.

CHSE Odisha Class 12 Alternative English Solutions Poem 5 Toads

Composition:

Question 1.
Assess the significance of the little “Toads”?
Answer:
The poem ‘Toads” is composed by Philip Larking, an eminent and out-standing poet of the post-war generation. His poetry responds to all the tints and flavours of provinced life. He has indeed great mastery in proving apt and suggestive title to his poems. His quality in this sense is superb and fantastic. This is a typical poem demonstrating this quality.

However, the title of work of art must be pointed, precise, concise, sharp and suggestive. It should be lie a colourful and attractive signboard which attracts the attention of the customers instantly. It can also show the inside contents of the shop. Similarly an attractive and suggestive title makes the reader spell bound to go through the piece of writing with much interest and fascination. The discussing poem ‘Toads” is sucha poem which satisfies all the characteristics of a good title. Toads are very inactive, rough and ugly creatures that sit heavy hindering its and other progress simultaneously.

The little taken from these living makes it clear that the toads keeping hanging on the poet which hinder his progress. Moreover, the poet starts the poem with two questions at the outset of the poem. One, “Why should I let the toad work/squat on my life?” Second, can I use my wit as a pitchfork/And drive the brute off?” The second stanza of the poem says that the toad soils six days of the week with its sickening poison just for paying a few bills that is out of proportion. A lot of people live on their wits. Lecturers, lispers, losels, loblolly- men, louts don’t end as paupers. Yet many more people live up lanes with fires in a bucket that eat winds falls and tinned sardines and seem to like it.

In the fifth stanza, the poet says that their children here got bare feet, their unspeakable wives are skinny as small thin racing dogs and yet no one actually stores. Had he been courageous enough to shout “stuff your pension” but he knows, all too well, that is the stuff that dreams are made on. In the seventh, eighth and ninth stanzas, the poet continues his thoughts saying that for something sufficiently toad-like squats in him to blarney his way to getting the fame and the girl and the money all at one sitting. He does not say that one bodies the other one’s spiritual truth but he does say that it is hard to lose either when one has the both. As a matter of fact, it is very much clear from the above description that, the title of the poem is apt and suggestive. The poet’s explanation about the toads as really fantastic, outstanding, though-provoking and appropriate.

Question 2.
Write an appreciation of the poem. First state the theme and say briefly how this theme is related to “Toads”. Then discuss how the problem is introduced and elaborated in the poem and whether there is any suggestion of a resolution of the problem. Also examine how the introducing stanza and the concluding stanza are related to each other and so the stanza in between. Identify the unusual words in the poem, if you find any and point out their relevance in the poem. And conclude your appreciation with your personnel response to the theme and its treatment in the poem.
Answer:
In fact, Philip Larkin’s poem ‘Toads” is his superb and fantastic composition. Here he expresses his disgust with a vice like grip of routined engagement. It is such a poem which satisfies the characteristics of a good poem. Toads are very inactive, rough and ugly creatures,
that sit heavy hindering its and the other’s progress simultaneously. The title taken from these living beings makes it clear that the toads keep hanging on the poet which hinder his progress.

However, the poet starts the poem with two questions at the outset of the poem One is –
“why should I let the toad work/squat on my life”? The second one is – “can’t I use my wit as a pitch work /And drive the brute off?” The second stanza of the poem says that the toad soils six days of the week with its sickening poison just for paying a few bills that is out of preparation. A lot of people live on their wits. Lecturers, lispers, losels, loblolly-men, louts don’t end as paupers yet, many more people live up lanes with fires in a bucket that act windfalls and tinned sardines and seemed to like it.

Moreover, the poet delineates in the fifth stanza that their children have got bare feet; their unspeakable wives are skinny as small racing dogs and yet no one actually shores”, but he knows all two well, that is the stuff that dreams are made on.

The initial’s sounds in the words ‘six’ ‘soils’ and the final ‘s’ sound in the words- ‘that’s, ‘proportion’; The I sounds in ‘tots’ ‘folk’, ‘live’, ‘lecturers’, ‘lispers’, ‘losels’, ‘loblolly-men’, Touts’ etc. are the alliterative sounds that enrich the poem As a matter of feet, the poem ‘Toads” of Philip Larkin is a typical masterpiece of suggestion which teaches and delights at one.

and outstanding. One the whole, the poem is inspiring, thought-provoking, elevating and heart-touching.

CHSE Odisha Class 12 Math Solutions Chapter 11 Differential Equations Exercise 11(b)

Solve the following differential equations.
Question 1.
\(\frac{d y}{d x}\) + y = e-x
Solution:
Given equation is \(\frac{d y}{d x}\) + y = e-x … (1)
This is a linear differential equation.
Here P = 1, Q = e-x
So the integrating factor
I.F. = e∫P dx = e∫dx = ex
The solution of (1) is given by
yex = ∫e-x . ex dx = ∫dx = x + C
⇒ y – xe-x + Ce-x

Question 2.
(x2 – 1)\(\frac{d y}{d x}\) + 2xy = 1
Solution:
Given equation is (x2 – 1)\(\frac{d y}{d x}\) + 2xy = 1

This is a linear equation where
P = sec x, Q = tan x
I.F. = e∫sec dx
= e(sec x + tan x) = sec x + tan x
The solution is y . (sec x + tan x)
= ∫(sec x + tan x) tan x dx
= ∫(sec x tan x + tan2 x) dx
= ∫(sec x . tan x + sec2 x – 1) dx
= ∫(sec x + tan x) – x + C
⇒ (y – 1) (sec x + tan x) + x = C

CHSE Odisha 11th Class English Notice Writing

Writing Notices

A notice is a written or printed news, announcement or information. It is usually displayed publicly on a school/college notice-board. A notice can also be given for insertion in a newspaper like an advertisement. But there is one main difference between an advertisement and a notice. An advertisement is chiefly commercial (or matrimonial) in nature; but a notice is a general piece of information for a particular group. A notice should be in complete sentences or even in the form of a short paragraph, whereas an advertisement can be in the form of merely catching phrase and slogans.

Question 15.
Why does he find this feeling strange?
Answer:
He finds this feeling strange, because of several factors such as his liking for fish fry and the taunting remarks of his family members. Besides, the speaker’s fear and anxiety give way to determination.

Question 16.
Do you think the speaker was sensitive? Why do you think so? (clue: at least two reasons)

Like a seasoned angler sure of his feat
With fishing rod and line, and bait
I said, “You all, wait for me
Fish-fry tonight our dinner will be.”

Though none of them did say a word
On my face, yet I heard
Some chuckles sure at my back
I told myself, “Let me come back.”

To the nearby pond I straighaway ran
With fishing-tackle, and of course, a can
The minutes passed and the hours dragged
It seemed no luck that day I had.

I thought fishless I’d return home
And would face the jeers of some
I threw my line with a fervent wish
“Oh God, today please give me a fish.”

And lo, the float sank, rose again
And popped its head to tell me then
“This is just the time, you man,
To catch a fish if you can.”

Without delay I pulled the string
And what a catch did it bring
A one-foot fish, bright and fair
That wriggled and wriggled in the air.

At this my joy knew no bound
I ran excited round and round,
But with a gasping mouth and wistful look
It seemed to say, “Please unhook
Me and let me go again
To my home, my waterly den.’’

I did think of my three hours’ labour
And the spicy fish-fry flavour

In the evening’s crimson glow
With greater joy, I let it go.

The sight of the teasing remarks of some family members haunted him if he went back home without a fish. He prayed to God, requesting him earnestly to give him a fish.

Introducing The Poet:
Gopal Ranjan Mishra has written some fascinating poems. They are marked by the simplicity of rhythm.

About The Poem:
‘Fishing’ deals with the fact that a rich source of joy is attributed to an act of kindness. The speaker who presents himself as a veteran angler is a glittering example.

Summary:
The speaker who identifies himself as a vastly experienced angler prepared himself for fishing. He declared to his family to wait for him. As a result, their dinner would be marked by fish fry. None of them spoke a word, yet they responded to his declaration in silent laughter. The speaker’s initial experience was one of bad luck. Minutes and hours trickled by. The nearby pond seemed to disappoint him. The chance of catching any fish did not look bright. He visualized the fear of facing rude remarks from some family members. He threw his line praying to God to give him a fish.

The speaker’s prayer did not go in vain. He had now a marvelous catch – ‘A one foot-high, bright and fair fish’. He saw it move in a twisted fashion in the air when the speaker pulled the string. He was beside himself with joy at the sight of the fish. His excitement ran high. In the meantime, it seemed to plead with the speaker for freedom. The fish’s earnest request to get it free sparked a debate in the speaker’s mind.

The thought of three hours’ toil, the spicy fish-fry taste, and of ‘some mocking face’ staring at him when he would come back fishless swam before his mind’s eye. However, he didn’t care for anything. The poem ends on a happy note. The sun was setting. A strange feeling filled the speaker’s heart. With a heart full of joy, he allowed the fish to go. In short, the speaker found great pleasure in his act of kindness.
