Question 41.
Describe the ‘Grand Prix’ at Cape Town’s Red Cross Children’s Hospital.
Answer:
The author describes the event as “the Grand Prix of Cape Town’s Red Cross Childrens’ Hospital”. A nurse had left a breakfast trolley unattended. Very soon this trolley was commandeered by a daring crew of two, a driver and a mechanic. The mechanic provided motor power by galloping along behind the trolley head down. While the driver, seated on the lower deck held on with one hand and steered it by scrapping his foot on the floor. The choice of roles was easy because the mechanic was totally blind and the driver had only one arm. It was better than Indianapolis 500 car race. Patients shouted and cheered the boys. There was a grand finale of scattered plates and silverware before the nurse and ward sister took control of the situation.

How did Hillary and Tenzing prepare themselves before they set off to the summit?
Answer:
They started up their cookers and drank lots of lemon juice and sugar. Then they took sardines and biscuits. Hillary cleaned the ice off the oxygen sets. He rechecked and tested them. He had removed his boots which had become wet the day before. They were now frozen solid. It would be very challenging to start climbing ice-cold Himalayas with such wet and chilling boots. So, he cooked them over the fierce flame of Primus and managed to soften them up.

They were also conscious of the probabilityof braving snow storms during the ascent.

They hoisted their 30 lb. of oxygen gear on their backs. Connecting their oxygen masks they turned on the valves to bring life-giving oxygen into their lungs. Taking a few deep breaths, they got ready to go.

Question 42.
How does nature communicate with the Toru Dutt?
Answer:
Like Wordsworth, Toru Dutt is also a great lover of nature. She has also had mystical experiences in communion with nature. The emotional bonding between herself and the giant Casuarina tree is beyond reason. When she is away on the shores of Italy and France, she could distinctly hear the dirge-like murmer of her beloved tree who obviously missed her. She could perceive it as the tree’s lament and eerie speech expressing its anguish over the long spells of her absence.

Ordinary human eyes will fail to perceive the distinct communication of the Casuarina tree. But through the eyes of faith, similar to William Wordsworth’s inward eye in the poem ‘Daffodils’ it is possible. She was able to vividly see in her inner vision the sublime form of the Casuarina tree. The surprising thing is that she was able to see the tree in its prime in her own “loved native clime.”

What is Ulysses’ clarion call to his sailors? How does he inspire them?
Answer:
In the third part of the poem, Ulysses makes a clarion call to his hearty compatriots (i.e.) mariners. They have been with him both during ‘thick and thin’ or thunders or sunshine. They had frolicsome time fighting along with Ulysses against great warriors and Gods in the past. Ulysses does not want to live in memory of glory. He believes they need not waste away their precious time in nostalgic memories just recounting their escapades to younger generation. He is conscious of the impending death in old age. But he tells it is not “too late to seek a newer world”.

The many “voices of the ocean” call out to the mariners to resume voyage. He does not want his compatriots to miss even an hour which could provide them novel experiences in their voyage. He persuades his compatriots to gather at the port as the sails are already puffing up welcoming them all. Their life would be one of fulfillment only when they venture out into the unknown on the seas. He uses an emotional bait to his mariners.

He highlights the probable outcome of their voyage. They might reach the “Happy Isles” (i.e.) great paradise and meet Achilles, their war hero. No matter how much strength they have, they still have some “strength of will” left to strive, to seek, to find, and not to yield.

Children reaction – touch of sunlight – tan themselves – teacher warns – take off jackets – jungle in the Venus – colour of stones – ran among trees – hide and seek – breathed off the fresh air – blessed sea of soundlessness – savoured everything – mirth for one hour.
Answer:
Children get really excited. They want to see the touch of sunlight on all form of life in the planet. They want to tan themselves in the new found warmth of the Sun. Children persist that they be allowed to go out to the Sun. The teacher allows them with a warning that they must be back in two hours. They start running and turning their faces up to the sky and feeling the Sun on their cheeks like a warm iron. They take off their jackets to allow the Sun to bum their arms.

They gladly shouted “Oh, its better than Sun lamps. Children stood in the great jungle in the Venus. The jungle was in the colour of stones as they had not seen the Sun for years. The children lay out laughing on the jungle mattresses and heard it sigh and squeak under them resilient and alive. They ran among the trees, they slipped and fell and pushed one another.

They played hide and seek. But most of them squinted at the sun until tears ran down their faces. They put their hands up to the yellowness and the amazing blueness, they breathed off the fresh air and listened to the silence in a blessed sea of soundlessness. They looked at everything and savoured everything. Like animals escaped from their caves, they ran shouting in circles. Their mirth continued for one hour.

Lord Weston – judge – pompous and vain – secretary Roger – displeasure over Roger’s request – piece of paper – warning – legal punishments – 15th of March – fair judgement – unperturbed by threat – precautionary measures – assassination attempt – a gardener – Weston’s absent-mindedness.
Answer:
‘Remember Caesar’ is a light hearted comedy. The name Caesar is the name of a tragic hero Julius Caesar in one of the plays of William Shakespeare. Weston gives an appointment to Mr. Caesar to discuss rose tree planting work in his garden. Just to remind him of the proffered appointment, he scribbles two words “Remember Caesar” and keeps that scrap
of paper in his coat pocket and has forgotten about it. On seeing that note, Lord Weston is shocked. Roger, the assistant of the judge elevates him to the level of a tragic hero.

He flatters the judge that his death could be a great loss to England as he was a great impartial judge. Mrs. Weston’s entry lightens up the whole drama and the tragedy transitions into a dark comedy. Lady Weston keeps hinting about earlier attempts when he was eating a game pie. When Weston says he has instructed Roger to barricade all doors, her immediate worry is about the grocery awaited. She asks if he was expecting both French and Dutch together in the attempt to assassinate. Lady Weston doesn’t want to send away the cook. She is practical.

She wants her to stay back to cook his pet dishes. Lady Weston brings a handful of candles to keep the room lit if Mr. Weston has to stay underground for a while. A velvet coat is construed as an infernal machine that could blow up the whole place is smothered with books inside a pail of water. The arrival of Mr. Caesar only sorts out the knot. The judge remembers to meet Mr. Caesar on 15th March.

Question 44.
Write a summary or Make notes of the following passage.
Answer:
When we survey our lives and efforts we soon observe that almost the whole of our actions and desires are bound up with the existence of other human beings. We notice that whole nature resembles that of the social animals. We eat food that others have produced, wear clothes that others have made, live in houses that others have built. The greater part of our knowledge and beliefs has been passed on to us by other people though the medium of a language which others have created. Without language and mental capacities, we would have been poor indeed comparable to higher animals.

We have, therefore, to admit that we owe our principal knowledge over the least to the fact of living in human society. The individual if left alone from birth would remain primitive and beast like in his thoughts and feelings to a degree that we can hardly imagine. The individual is what he is and has the significance that he has, not much in virtue of the individuality, but rather as a member of a great human community, which directs his material and spiritual existence from the cradle to grave.

Rough Draft

Being social animals, human beings have their actions and desires bound up with society. In matter of food clothes knowledge and belief they are interdependent with one another. We eat food that others have procedure Wear clothes that others have made, live in houses that others have built. They use language created by others. Without language their mental power would not grow.

We have to admit that we owe principal knowledge over the least to the fact of living in human society. The individual if left alone from birth would remain primitive. They are superior to beast, because they live in human society. An individual life left alone from birth would grow utterly beast like. So human society and not individuality guides man’s material and spiritual existence.

Fair Draft: Man is a Social Animal

Write a paragraph of 150 words on “Hazards Of Reckless Driving”.
Answer:
Hazards Of Reckless Driving

Careless driving is one of the leading causes of accidents. When a driver fails to drive with due. care, it can cause serious harm to others sharing the road. I had a bitter experience of such reckless driving last month while returning from GGHS School, which is just a kilometre away from my house. As I was returning home around 5.30 p.m., after Math coaching class, I heard some screaming behind me and hence just turned to see what the sound was about.

The very next second, I was knocked down by a speeding motorcycle. I had a hairline crack on my right ankle and bruises on my right arm. I was really lucky that I did not have major issues. However, I was in a state of severe shock for more than a week and I dreaded stepping out on the road. There should be severe actions taken against those who violate traffic rules.

A long time ago there lived a monster called the sphinx. She had the head of a woman, the body of a lion and the wings of a big bird. Her eyes were so fierce that nobody dared to look at her face. The sphinx sat on a cliff outside the city of Thebes. When a man passed by her, she would ask him a riddle. The man had to give the right answer, or the sphinx would eat him up. The riddle was so difficult that no one could answer it.

Many men lost their lives and people were afraid to come out of their houses. Then one day a clever man wanted to answer the sphinx. His name was Oedipus and he was not afraid of the sphinx. The sphinx stopped and asked him a riddle “what walks on four legs in the morning, on two legs at noon and on three legs in the evening?”

She jumped off the cliff and ended her life.

Question 41.
What are the aspects that contribute to humour in the essay?
Answer:
The author claims the best manner of making tea is the subject matter of violent disputes. He compliments china tea for being economical but also says one does not feel rejuvenated after drinking it. One doesn’t feel braver, wiser, more optimistic or stimulated after drinking the Chinese tea. He says army tea tastes of grease and white wash. In Britain there are two schools of thought (i.e.) milk first school and tea first school (i.e.) one school claiming that milk must be poured first and tea added later and another school claiming that tea must be poured first and milk to be added next.

He says those who take tea with sugar for its sweetness alone as misguided people. He says that they could very well add salt and pepper to tea and drink it. He claims that there are some mysterious social etiquette surrounding teapot. It is vulgar to drink tea out of one’s saucer. There are some subsidiary uses of tea leaves such as telling fortunes, predicting the arrival of visitors, feeding rabbits, healing burns and sweeping the carpet.

“My right to swing my fist ends, where your nose begins.” Elucidate with reference to, ‘On the Rule of the Road’.
Answer:
Rights are not completely individual affairs. In order to enjoy one’s rights one has to respect the rights of others too. The lady in Petrograd had the right to walk on the pavement. The right to move stops when the other person’s right to drive starts. A person may have a walking stick and roll it too. But his right just stops where the other person’s nose begins. No one has the right to violate the rights of others. The right, one exercises, must not affect or erode the rights of others.

One should not think of one’s own rights but also the rights of others. A.G.Gardiner beautifully illustrates this idea by emphasising the metaphor of traffic rules. Rules of road are in fact rules of politeness and unselfishness. One may have absolute freedom in the choice of food, religion, fashionable dress, up keep of hair, funny hairstyle, etc. But one must be conscious of the rights of others. So, the statement “my right to swing my fist ends, where your nose begins” fits well with the central theme of the essay ‘ On the Rule of the Road’.

Question 42.
Human greed led to the mighty fall of the citadel. Explain.
Answer:
The loyal soldiers and their brave captain expected enemies from outside the castle. Their arms and army was ready to fight them. But they could not identify the enemy within. The soldiers were proud that no might would tear their castle down. But they were unaware of the invisible soul-dead enemy within. The ingredients of personal downfall went unnoticed by them.

If a person never looks within, the faults that can be their doom go overlooked. Their reality could crumble while they gaze outward and pride themselves on their sureness. This is what happened precisely with the soldiers of the castle. They only focused on the strength of their physical surroundings and what was beyond the castle. Human greed-propelled betrayal from within caused the castle’s downfall.

Explain how the poet guides his son who is at the threshold of manhood, to face the challenges of life.
Answer:
The poet shares his wisdom with his son who is at the threshold of manhood. He persuades his son to be hard like steel or rock to withstand challenges and unforeseen betrayals in life. A person with soft heart will crumble before a breach of trust. Similarly he wants his son to be discerning enough to be soft when needed to grow like a frail flower plant splitting a rock.

Occasionally one has to go with the current because life is at times fertile with a lot of opportunities to grow even among the harshest circumstances. ‘Rich soft wanting’ can help a person to win against all odds. He reiterates this idea by explaining how gentleness can reform a hardened criminal when lashes would, in contrast, harden them further.

Question 43.
Write a paragraph of about 150 words by developing the following hints:
Pi convinced – water on board – divining rod – Pi’s mind – genuine regulation lifeboat – outfitted with supplies – captain – ensure safety and survival – ship chandler – extra money-saving lives – water on board.
Answer:
Pi had never before experienced physical hell than that putrid taste and pasty feeling in the mouth. It was an unbearable pressure at the back of his throat. The divining rod in Pi’s mind dipped sharply and spring gushed forth. He remembered that he was on a genuine regulation lifeboat and such a lifeboat was surely outfitted with supplies. A captain would never fail in so elementary way of preserving water to ensure safety and survival of his crew in the event of a disaster. Besides, it is natural that a ship chandler would think of making a little extra money under the noble pretext of saving lives. It was settled beyond doubt that there was water on board.

Bond of friendship – Baldwin and Gresham – boyhood chums – school together – lifetime bondage – thirty five years – baptism – 60 dollars a week – Governor of the private bank – Gresham siphoning money – loyalty and honesty – part ways – upright character – close the bank – return the deposit – reorganization of the bank – arrest – court could not nail Gresham – one hundred thousand dollars – three words – slapped him – body language – not compromise with conscience.
Answer:
Baldwin and Gresham were boyhood chums. They went to school together. Their friendship flowered into a lifetime bondage as it was sustained for thirty five years. When Baldwin’s son was being baptised in the church, Gresham was present. Baldwin expressed his wish that his son John Gresham Baldwin grew up to Gresham’s standard in life. Baldwin was paid only 60 dollars a week for working as a Governor of the private bank founded by Gresham.

Accidentally, Baldwin found out how Gresham was siphoning money very cleverly from the deposits technically without really causing any loss to the depositors. But Baldwin was loyal to Gresham only as long as he was honest. Once he parted ways with honesty, Baldwin would also part ways with Gresham. By the force of his upright character, Baldwin advised him to close the bank and return the deposit to the customers.

Tamil Nadu 12th English Model Question Paper 4

Third National Bank was ready to help the reorganization of the bank. Meanwhile, Gresham was arrested. The court could not nail Gresham as there was not a shred of evidence to prove his guilt. If Baldwin testified, the court would indict him. Just before being arrested Gresham offered him one hundred thousand dollars to just say “I don’t remember”. The three words to let him off the hook. He claimed it was the difference between the salary he had been paid and what he ought to have received. Had it been someone else, Baldwin would have slapped him.

But it was Gresham who understood his body language and did not press the matter further. He was proud of the fact that Gresham understood how he could not compromise with his conscience. His family members Martha, Evie and John felt that it was a compliment that cost him one hundred thousand dollars. Baldwin said that Gresham’s compliment about his uprightness was worth a hundred thousand dollars.

Question 44.
Write a summary or Make notes of the following passage.
Answer:
Occasional self-medication has always been part of normal living. The making and selling of drugs has a long history and is closely linked, like medical practice itself, with belief in magic. Only during the last hundred years or so, as the development of scientific techniques made it possible, diagnosis has become possible. The doctor is now able to follow up the correct diagnosis of many illnesses – with specific treatment of their causes. In many other illnesses of which the causes remain unknown, he is still limited, like the unqualified prescriber, to the treatment of symptoms.

Tamil Nadu 12th English Model Question Paper 4

The doctor is trained to decide when to treat symptoms only and when to attack the cause. This is the essential difference between medical prescribing and self-medication. The advance of technology has brought about much progress in some fields of medicine, including the development of scientific drug therapy. Parallel with such beneficial trends are two which have an adverse effect. One is the use of high pressure advertising by the pharmaceutical industry which has tended to influence both patients and doctors and has led to the overuse of drugs generally.

The other is emergence of eating, insufficient sleep, excessive smoking and drinking. People with disorders arising from faulty habits such as these, as well as from unhappy human relationships, often resort to self-medication. Advertisers go to great lengths to catch this market. Clever advertising, aimed at chronic sufferers who will try anything because doctors have not been able to cure them, can induce such faith in a preparation, particularly if steeply priced, that it will produce -by suggestion- a very real effect in some people.

It is doubtful whether taking these things ever improves a person’s health, it may even make it worse. Worse, because the preparation may contain unsuitable ingredients; worse because the taker may become dependent on them; worse because they might be taken excess; worse because they may cause poisoning, and worst of all because symptoms of some serious underlying cause may be asked and therefore medical help may not be sought. Self-diagnosis is a greater danger than self-medication.

Rough Draft
Self-medication is part of normal living. Medicinal experts are required for diagnosis and treatment of diseases according to symptoms and causes. The development of drug therapy and improvement in public health organizations and nutritional standards have helped progress in medicinal science. Excessive advertising by pharmaceutical companies and emergence of the sedentary society are two counter trends. Self-medication is dangerous as the preparation may be toxic or contain unsuitable ingredients; the user becomes dependent and consumes medicine in excess. Self-diagnosis is worse than self-medication.

Write a paragraph of 150 words on “Punctuality”.
Answer:
It has been said, “Never put off for tomorrow what you can do today”. Yet there are many people who enjoy postponing things. Such people do not realize the dangers of delaying. Work does not disappear if we postpone it. The difficulty of the work does not get reduced by postponing it. The more we postpone, the more the work piles up. Finally, the load of work seems too much. We then have to work for many days at a stretch under great strain and tension. Finally we do it hurriedly and in a careless manner.

It is as bad as not doing the work at all. Again, when some work is delayed, the time which would have been profitably used is wasted. Time wasted is time lost forever. Hence procrastination, that is the habit of postponing things, is rightly called the thief of time. Precious time wasted means opportunities lost, and lost forever. By the time we realize how much time we have wasted and how many opportunities we have missed by delaying word, it may be too late.

Tamil Nadu 12th English Model Question Paper 4

And then nothing remains for us except to regret and repent. Sometimes a very heavy price has to be paid for delaying things. The person who delays insuring his factory will regret it when the factory is gutted by a sudden fire. Delay in the treatment of a disease may make it worse, and may even result in death. There are other proverbs conveying similar meaning. Thus we say: “Time and tide wait for no man” and “A stitch in time saves nine”. All these proverbs warn us against the dangers of delay in actions, and stress the importance of timely action and punctuality.

I will maintain until my death
Answer:
Reference: This line is from Edwin Muir’s poem “The Castle”.

Tamil Nadu 12th English Model Question Paper 5

Context: The poet says this while recounting the shameful act of betrayal by the aged warder of the wicket gate.

Explanation: The narrator was overconfident of the invincibility of their castle, their stock piled arms and well-stocked granary. They had a brave captain and loyal soldiers. In an open war, they need not fear defeat as their friendly neighbours were also willing to join them during a war against any invader. But their enemy was within their fortified castle. They were sold for a bag of gold. Without a groan the citadel was captured. It was a shameful way to lose one’s side. So, the narrator prefers not to recount this shameful secret to anyone so long as he is alive.

Answer:
Reference: These lines are from the poem ‘All the world’s a stage’ written by William Shakespeare.

Explanation: The poet beautifully says the “eventful history” (i.e.) life which was spiced up with many interesting things is now coming to a dramatic close. The eternal jewel of life, ‘the soul’, is going to depart the body which had kept it imprisoned for long. The soul celebrates the joy of freedom in death.

Explanation: The poet asks his son to take advantage of the loneliness. He must enjoy the advantages of solitude. Solitude would help him to be creative. He would invariably learn that final decisions are always taken in silent rooms. In solitude he can pursue his creative imagination and succeed like Shakespeare, Wright brothers, Pasteur, Pavlov and Faraday.

Question 41.
How did a casual incident in a hospital help Dr. Barnard perceive a new dimension of life?
Answer:
Initially Dr. Barnard was grumbling. He wondered why on earth he and his wife should have been subjected to agony and inconvenience. He couldn’t take his dad’s view that suffering ennobles human beings. But the little boys taught him a profound lesson of life. One should get on with the business of living irrespective of whatever misfortune strikes one.

You don’t become a better person because you suffered, your suffering does not ennoble you. But you become a better person because you have experienced suffering. It is not what you have lost is important. What is important is what you have left. We can appreciate light better once we have experienced darkness. Similarly, we can appreciate warmth only after experiencing cold.

The ridge had Hillary and Tenzing two and half hours, but it seemed like lifetime. Why?
Answer:
Both Hillary and Tenzing reached a wide ledge. Hillary deeply felt the fierce determination that nothing could stop them from scaling the Himalayas. He took a stronghold on the ledge and signalled Tenzing to come up. With great difficulty Tenzing reached the way up the crack and collapsed like a giant fish hauled up from the ocean. There were giant cornices on the right and steep rock sloped on the left. The ridge curved away to the right. They had no idea where the peak was.

As Hillary cut around the back of one hump, another would swing anew to his view. Time seemed never-ending. Their original zest started diminishing. The climb was becoming a grim struggle. To their surprise, the ridge ahead now dropped sharply away. A few more whacks of the ice-axe in the firm snow, they stood on top. It was Question 11.30, the ridge had taken two and a half hours. But it seemed like a lifetime as they had to negotiate numerous ridges on the way.

Give the summary of the poem, “Our Casuarina Tree’.
Answer:
The poet Torn Dutt describes the perpetually young Casuarina tree in this poem. The tree is tall and mighty. A creeper winds around its huge and wide trunk like a python. Birds chirp happily. The poet is ecstatic seeing the tree from her casement / window. In fact, she greets the tree everyday soon after getting up from bed. She finds a baboon sitting like a statue on top of the tree. The cows are grazing in the lush green meadows around the tree. Water lilies add to the charm of the pond. She recalls that the tree is dear not because of its majestic looks but because of the nostalgic memories attached to it.

Tamil Nadu 12th English Model Question Paper 5

She remembers the happy times she had spent with her siblings, who are now no more, under the tree. They died of consumption. Their absence makes the tree much more endearing to the poet. Mysteriously she hears the grief- filled lament of the tree when she is on the shores of France and Italy. She consecrates the tree’s memory to her dear departed siblings. Taking inspiration from William Wordsworth’s poem ‘Yew-trees’, she also wishes to immortalize the Cauarina tree. So she sings about it in her poem.

What is the role of the young soldier in the victory of the French at Ratisbon?
Answer:
The young soldier was one of the soldiers in the infantry division leading the battle. On storming Ratisbon, unmindful of the cannon fire, he climbed the flag post with French flag and hoisted it. He received the bullets in turn for his service to the emperor and French army. He did not succumb to the bullets immediately, he galloped on horse back to convey the news to emperor Napoleon Bonaparte himself.

He held on to life till he reached Napoleon and conveyed the happy news. He waited with abated breath to know the reaction of his great leader. When he expressed his sadness, his pride was hurt. He denied the emperor’s sympathy and said emphatically that he was killed. He fell down beside emperor Napoleon with a smiling face and died.

Question 43.
Write a paragraph of about 150 words by developing the following hints:
Ivan – tongue-tied – knife – moral shock – innocent victim – faith in justice – wife’s suspicion – loses hopes – belief in God – divine justice. Tsar’s judgement- mills of justice grind slow – Semyonich confesses – cruel joke
Answer:
Ivan is tongue-tied when the police finds knife in his bag. The moral shock he undergoes as an innocent victim of circumstances allows him to have faith injustice. But the moment his wife expresses her suspicion over his involvement in the murder, he loses all hopes. It is then that he starts believing in God and divine justice.

Tsar can’t give him freedom. His judgement is based on evidences given by crooked people. God need not be given any evidences of innocence. He knows the truth but his mills of justice grind very slow. Ivan loses interest in escaping or leaving the prison. He had no one to go back to. At this juncture, Semyonich confesses his guilt of murdering the merchant. When the pardon arrives as a cruel joke, Ivan is dead. So, ‘God knows the truth but waits’ is the most appropriate title for this story.

Sermon on diligence – Roger demands half-day leave – value of hard work – an impartial judge – switches off attention – take notes – self-indulgent absent-mindedness – escapes – rewinds memory – hoodwinks the judge – interview the award committee – judge was quite impressed – Mr. Clay’s office – orderly mind – excel in any learned profession
Answer:
In the beginning of the play Roger demands half-day leave and that was enough for the judge to start his sermon on the value of hard work and his standing in the society as an impartial judge. Roger conveniently switches off his attention and pretends to take notes of the instructions of the judge. The judge almost catches in his self-indulgent absent-mindedness. Roger escapes by the skin of his teeth by just rewinding from his memory the oft-repeated story of his success.

He hoodwinks the judge as to the purpose of his demand for half-a-day leave by saying that he wanted to personally interview the award committee as to why they had not forwarded the documents. The judge was quite impressed. The judge asked him to walk to Mr. Clay’s office in the afternoon. He reiterated that diligence, courage and attention to details are required to cultivate an orderly mind. Without an orderly mind no man can hope to excel in any learned profession.

Tamil Nadu 12th English Model Question Paper 5

Read the following passage and answer the questions in your own words.
Answer:
Black holes are one of the most mysterious and powerful forces in the universe. But what exactly are they? Are they simply holes that are black? Well, there’s more to it than that. A black hole is not a regular object with a surface area, like a planet. Instead, it’s an area in space where matter has literally collapsed onto itself. Black holes are formed when giant stars run out of energy. They end their life cycle and explode. This massive explosion is called a supernova. If the star has enough mass, it will collapse onto itself into a super small size.

Imagine an enormous mass squeezed into a tiny space. That space would become compact and dense. This causes the gravitational pull to be extremely strong. It will gobble up and absorb anything in its way, even gigantic stars. Nothing can move fast enough to escape its gravity. Not even light, the fastest thing in the universe! Black holes will gobble up anything and everything in their path, including light.

What happens to an object that gets sucked into a black hole? It will be literally stretched to its breaking point. Luckily, we don’t have to worry about black holes swallowing up our solar system. That’s because the nearest black hole is about 27,000 light-years away! Here’s a strange fact: black holes cannot actually be seen. That’s because they don’t deflect light. So how can we be certain they exist? Scientists discovered them by observing light and objects around them.

Tamil Nadu 12th English Model Question Paper 5

They noticed that black holes affected their surroundings like nearby dust, stars, and galaxies. Two different scientists from the 18th century named John Michell and Pierre-Simon Laplace first observed them. Then in 1967, a physicist named John Archibald Wheeler came up with the term “black hole”.

Black holes come in different sizes. Some are about the mass of one star. These are called “stellar” black holes. Others can grow and become huge. They may continue to absorb light, mass, and even stars around them. These are called “super-massive black holes.” They can be one million times more massive than our sun. Many scientists believe these super-massive black holes often exist right at the center of galaxies. In fact, we have one right in the middle of our very own Milky Way.

Questions:
a. Based on the information in the article, what is a black hole?
b. Who first discovered the existence of black holes?
c. Why are black holes dangerous?
d. Are all black holes the same size? Explain.
e. Why can’t black holes be seen?
Answers:
(a) A black hole is one of the most mysterious and powerful forces in the universe, an area in space where matter has collapsed in on itself.
(b) Two different scientists from the 18th century named John Michell and Pierre-Simon Laplace first discovered the existence of black holes.
(c) Black holes pull in anything that gets too close and stretch things to their breaking point and hence they are dangerous.
(d) No. Some black holes are the size of a single star. These are called stellar black holes. Others are the size of a million stars the size of our sun, or larger. These are called super- massive black holes.
(e) Black holes cannot actually be seen because they don’t deflect light. They can only be discovered by observing light and objects around them.

Question 1.
If z1 = 1 – 3i, z2 = -4i, and z3 = 5, show that
(i) (z1 + z2) + z3 = z1 + (z2 + z3)
Solution:
z1 = 1 – 3i, z2 = -4i, z3 = 5
(z1 + z2) + z3
= (1 – 3i – 4i) + 5
= (1 – 7i) + 5
= 6 – 7i …… (1)
z1 + (z2 + z3)
= (1 – 3i) + (-4i + 5)
= 6 – 7i ……. (2)
from (1) & (2) we get
∴ (z1 + z2) + z3 = z1 + (z2 + z3)

Samacheer Kalvi 12th Maths Guide Chapter 2 Complex Numbers Ex 2.3

(ii) (z1 z2)z3 = z1(z2 z3)
Solution:
(z1 z2) z3 = [(1 – 3i) (-4i]5
= [-4i + 12 i2]5
= [-12 – 4i] 5
= -60 – 20i ……. (1)
z1 (z2 z3) = (1 – 3i)[(-4i)(5)]
= (-20i + 60 i2)
= -20i – 60 ……. (2)
from (1) & (2) we get
∴ (z1 z2)(z3) = z1 (z2 z3)

Samacheer Kalvi 12th Maths Guide Chapter 2 Complex Numbers Ex 2.3

Question 2.
If z1 = 3, z2 = 7i, and z3 = 5 + 4i, show that
(i) z1(z2 + z3) = z1 z2 + z1 z3
Solution:
z1 = 3, z2 = 7i, z3 = 5 + 4i
z2 + z3 = -7i + 5 + 4i
= 5 – 3i
z1 (z2 + z3) = 3 (5 – 3i) + 15 – 9i …………. (1)
z1 z2 = 3(-7i) = -21i
z1 z3 = 3(5 + 4i) = 15 + 12i
z1 z2 + z1 z3 = -21i + 15 + 12i
= 15 – 9i ……… (2)
∴ from 1 and 2
z1(z2 + z3) = z1 z2 + z1 z3

Question 3.
If z1 = 2 + 5i, z2 = – 3 – 4i, and z3 = 1 + i, find the additive and multiplicative inverse of z1, z2 and z3.
Solution:
(i) z1 = 2 + 5i
additive inverse z1 is -z1
⇒ -(2 + 5i) = -2 – 5i
Multiplicative inverse z1 is (z1)-1
We know
z1 z1-1 = 1
⇒ (2 + 5i) (u + iv) = 1 [∵ z-1 = u + iv]
2u + 2iv + 5iu – 5v = 1
(2u – 5v) + i (5u + 2v) = 1 + i 0

Question 3.
By using Gaussian elimination method, balance the chemical -reaction equation:
C2H6 + O2 → H2O + CO2.
Solution:
We are searching for positive integers x1, x2, x3 and x4
x1 C2H6 + x2 O2 → x3 H2O + x4 CO2 ……….(1)
The number of carbon atoms on the LHS of (1) should be equal to the number of carbon atoms on the RHS of (1) so we get a linear
homogeneous equation.
2x1 x4 = 2x1 – x4 = 0 ……..(2)
6x1 = 2x3 = 6x1 – 2x3 = 0
÷ 2 ⇒ 3x1 – x3 = 0 ………(3)
2x2 = x3 + 2x4 ⇒ 2x2 – x3 – 2x4 = 0 ……… (4)
Equation (2), (3) and (4) constitute a homogeneous system of linear equations in four unknowns.
Augmented matrix

The system is consistent and has an infinite number of solutions.
Writing the equations using the echelon form we get
-2x3 + 3x4 = 0 ……….. (1)
2x2 – x3 – 2x4 = 0 ………… (2)
2x1 – x4 = 0 …………. (3)
Put x4 = t
(3) ⇒ 2x1 – t = 0
x1 = \(\frac {t}{2}\)
(1) ⇒ -2x3 + 3x4 = 0
-2x3 = -3t
x3 = \(\frac {3}{2}\) t
(2) ⇒ 2x2 – x3 – 2x4 = 0
2x2 – \(\frac {3}{2}\) t – 2t = 0
2x2 = \(\frac {3}{2}\) t + 2t = \(\frac {7t}{2}\)
x2 = \(\frac {7t}{4}\)
(x1, x2, x3, x4) = (\(\frac {t}{2}\), \(\frac {7t}{4}\), \(\frac {3}{2}\)t, t) ∀ t ∈ R
since x1, x2, x3 and x4 are positive integers.
Let us choose t = 4
