Question 3.
“A paradox may refer to a person, a thing or a situation that has two opposite features and therefore seems strange”. In light of this definition, how is ‘MAD’ a paradox?
Answer:
The acronym MAD means Mutually Assured Destruction. It’s paradoxical because nations amass nuclear weapons with the argument that it’s for self-defense. But if they use them by any chance it will lead to their destruction because the enemies will use their weapons as well and since the weapons have the capacity to destroy whole nations, the whole world may get annihilated.

Question 4.
What was the ‘problem’ that the nuclear powers had faced? Was it a violation of the agreement or was it the detection of violation? Explain briefly.
Answer:
The problem faced by the nuclear powers was the possibility of breach of trust. Supposing nations sign a treaty banning nuclear explosions, and if one or the other nation breaks the bond, how would the other nations know about it. Thus the problem is both the violation of the agreement and the detection of it.

Question 5.
Why were the technical experts summoned by the three superpowers?
Answer:
The three superpowers had enough nuclear bombs to destroy others. If anyone of them used, it would take only 20 minutes to reach their targets, but other side had plenty of time to reverse action against their enemy. So the three superpowers were willing to come to an agreement to solve the problem. Hence they summoned the technical experts.

Question 6.
In which area did Kellis Brooks theoretical knowledge has a direct application?
Answer:
Keilis-Borok was doing research on the theory of seismic waves – tremors generated by an earthquake.

Question 7.
“Iron Curtain” is referred to as a barrier. It was outwardly difficult for the opposite sides of the iron curtain to find out the solution for the problem of violation of the agreement. What was the reason?
Answer:
Iron curtain was a barrier. It was difficult for the opposite sides to find out the solution. Because of the cold war continued, the political tensions were hanging over. The scientists gave up their differences and worked together irrespective of their nationality.

Question 8.
How are scientists able to work in spite of political and cultural differences?
Answer:
According to the author, scientists should give up their cultural differences and work hard for the benefit of the whole of mankind. Scientists were able to work, based on respect to hard evidence known to be true something and they were skillful.

Answer:
The people who trained in theoretical physics are headhunted by financial institutions. Those who trained in frontiers of biological research become founders and directors in the pharmaceutical industry.

Question 12.
Some statements are given below. Why or why not are they true?
a) Money is more powerful than intellectual resources.
b) Intellectual resources help the survival of mankind.
c) Basic research is a way of stalling disasters.
Answer:
a) Money is more important than intellectual resources – False
There is no assurance that money can buy everything. In fact many problems are created by money. But intellectual resources, of which science is the most significant, can improve the quality of life.

b) Intellectual resources help the survival of mankind – True
It is because of the intellectual resources that we have combated many diseases. Though man is not the fittest among all the creations of God, he is able to ensure his safety against the other powerful creatures of nature because of his intellectual resources. Basic research can help our survival by giving us new sources of energy and new mineral deposits. Basic research can also protect us against terrorism.

c) Basic research is a way of stalling disasters – True
Meteorologists study the ecological changes and forewarn people about natural disasters like earthquakes, tsunamis, storms etc. People can be evacuated from the area posed with danger.

Answer the following questions in 2-3 sentences each:

Question 1.
In addition to war, what other man-made disasters are cited by the author?
Answer:
A massive release of radioactivity from nuclear waste disposal and an outburst of mass violence are cited by the author as man-made disasters.

Question 2.
What did the writer learn from his experience in Geneva?
Answer:
The episode at Geneva taught the writer that as a scientist he had people all over the world who thought and interacted the way he did. It taught him never to feel lonely abroad. And, above all, it taught him that while there is science, there is hope of survival and well-being for all of us.

Question 3.
How did the threat of mutually assured destruction protect the world?
Answer:
At the height of the cold war, every superpower had more than enough nuclear bombs to destroy the others in the first strike. If one country sent a nuclear missile to the enemy country, the enemy could know it immediately and retaliate by sending its own missile in the opposite direction. In the bargain, nations would destroy each other mutually. This threat of mutually assured destruction was for some years the only thin thread protecting the world from destruction.

Question 4.
Why did the scientists meet at Geneva?
OR
‘Technical experts were summoned to solve the problem that arose’. What was the problem?
OR
Why did technical experts from the nuclear power nations meet in Geneva? The scientists met at Geneva to discuss the problem of nuclear weapons. Since the tremor caused by an earthquake was the same as the tremor caused by a nuclear explosion, if countries which signed the treaty violated the terms, it would be difficult to know the violation. So the technical experts from the Soviet Union, United States and United Kingdom – three powers possessing nuclear weapons – met to come up with suggestions.

Question 5.
Why does Keilis-Borok feel that science is the indispensable guardian and caretaker of humanity? Support the statement with examples.
Answer:
Keilis-Borok feels that only the basic research in science can create a springboard
for developing new disaster-preparedness industry. Science is not the beginning and not the end either. If humanly used, it is their indispensable guardian and caretaker. In the present scenario the safety of mankind is threatened by both natural and man-made disasters. Be it a tsunami, be it terrorism, money alone cannot tackle the problem. Scientific solutions are the only hope. Thus the author has umpteen reasons to conclude that science is the hope of survival.

Question 6.
“Science is our indispensable guardian and caretaker”. Support this statement with a few examples which illustrate the writer’s stand.
Answer:
Science is our indispensable guardian and caretaker because it is only Science that can ensure that we move with time safely. When it comes to the question of ensuring that countries that have signed the treaty of not carrying out nuclear explosions keep to their word, it is only Science that can differentiate between the tremors caused by nuclear explosions and natural earthquakes. It is Science that can give us new sources of energy, new mineral deposits, and efficient defense from terrorism.

Answer the following questions in 5-6 / 8-10 sentences each:

Question 1.
When the author compares writers and scientists, what does he want to achieve?
Answer:
By comparing a writer and a scientist, the author wants to highlight the degree of involvement these two professionals have with their work. Though writers and scientists don’t have much in common as far as their work is concerned, the author brings them together for comparison because their attitude to their work is the same. Just as a writer writes because he cannot live without writing, a scientist experiments because he is passionate about the joy of discovery.

Question 2.
Which are the natural and man-made disasters that threaten our civilization?
OR
What are the commonly recognized threats for the survival of our civilization?
Answer:
The very survival of our civilization is threatened by natural and man-made disasters. Among them are earthquakes, self-inflicted destruction of megacities, environmental catastrophes, economic and social crises. Today, a massive release of radioactivity from a nuclear waste disposal, an earthquake in the middle of a megalopolis, an outburst of mass violence, or any other global disaster, can cause up to a million of casualties, render large part of our world uninhabitable, trigger global economic depression, or a war in a ‘hot’ region.

Read the following extracts and answer the questions given below them:

Question 1.

Science and Hope of Survival Summary in English

This prose is written by Kellis – Borok. He is a scientist and doing his research on the theory of seismic waves – tremors which is produced during an earthquake. There is a popular statement that if the person is so clever, why he is being so poor? Many youngsters want to become a scientist though it didn’t give much money When compared to the other professions like Business, Law, Medicine.

According to Leo Tolstoy that a writer is not merely a person who writes. A Writer is a person who cannot live without writing. Similarly, the author believed it is true for scientists also. The scientists would get money and honor only after their discovery. Instead of money, they get freedom, friendship, and independence. The honors and promotions would depend on scientists themselves and they would get the feeling of revealing the secrets of nature.

The present situation is proof upon the sayings of Frank Press that “An instant understanding, the efficiency of thought and action, and a good feeling that comes when the like-minded people to work together. At the time of cold war in I960 when the author was in Moscow and doing his research and involved in his problem; he enjoyed the mathematical challenge. He did not give much importance to how it connects to real life. One day he got the call from the President of the Russian Academy of Sciences. He had received the message from the Palace of Nations in Geneva.

The technical experts from the Soviet Union, the United States and the United Kingdom who had possessing nuclear weapons met behind closed doors. The President showed the letter from Geneva, an American Scientists, Frank Press quoted the authors work while arguing with Moscow experts. For his great surprize, the author had to attend the Geneva conference. At that time, everyone on the world was living under the threat of destruction which may cause by nuclear weapons. All three superpowers had enough nuclear bombs to destroy others. If anyone of them used, it would take 20 minutes to reach their targets but the other side had plenty of time to launch the reverse action against their enemies ensuring the destruction with the ominous acronym “MAD”. This MAD gave only a thin thread of protecting from the common destructive destiny.

The invention of more stronger bombs creates more imbalance. So the three nuclear powers were willing to come to an agreement, putting a ban on the nuclear weapon test. Hence, technical experts were called to solve the problem that arose.
The two problems were –

• The nuclear powers had signed an agreement to stop the test of the new nuclear weapons
• One of the participants had violated this agreement and secretly made an underground nuclear explosion. The problem was how can the other powers detect the violation?

This problem had a direct connection with the theory of seismic waves. The nuclear explosions produced earth tremors which are similar to those produced by earthquakes. How to identify whether the tremors are from an earthquake or by the nuclear explosion. The authors the theoretical knowledge had a direct application in the area of survival of the humankind. In this critical situation, with political tensions, Scientists and Engineers from the! opposite sides of the curtain had to find a solution, it seemed to be impossible. So according to author the scientists should give up their cultural differences and work hard for the benefit of the whole mankind.

Scientists were able to work, based on respect to hard evidence, known to be true ranking and they were skillful. They were working together to find a solution. Based on this the politicians took the most important decisions of their time Nuclear Test Ban.
From this event, the author learned that

• he had similar people who think and interact like him all over the world.
• There is no need to feel lonely in abroad.
• Where there is science, there is the hope of survival and well being for all.

There is a general saying that scientists do not have a practical or general sense. In one or the other case, it may be true that the famous mathematician while thinking or involved in the subject may wear shoes of different pairs. However, if we look carefully we can find the other side of it. Scientists are the most practical people in the world. All new technologies, a new branch of industries from defense to entertainment are the fruit of scientists research.

The antibiotics, electronics, biotechnology synthetic fibers, the green revolution, genetic forensic diagnosis, etc., The basic scientific research could give us new sources of energy, new mineral deposits and efficient defense from terrorism, cure from cancer, forms of transportation, etc., These are all contributions of scientists. It is very common that the survival of our civilization is threatened by natural and man-made disasters. The most common are earthquakes, self – inflicted destructions of megacities, environmental great disaster, economic and social crisis.

The solid release of radioactivity from a nuclear waste disposal, an earthquake in the middle of a densely populated cities, an outburst of mass violence, or any other global disaster can cause millions of casualties, Even it can cause a large part of our world uninhabitable and quickens the global economic depression or a war in a “hot” region. These are controlled by known techniques and spent one lakh crores of dollars.

The hope and the responsibility for breaking the agreement depend not only on money but on intellectual resources. According to French Proverb, Nobody is satisfied with his wealth, but everybody is satisfied with his wisdom. Only the basic research can create a springboard for developing new disaster preparedness industry. I George Bundy says that “Ours is the time of contest over issues” not completely understood.

Scientific research is an exciting venture into the great unknown. It had a great role in human survival. We all safely move by the scientist’s tools. Finally, the author reminds us that science is not beginning or end. If it is humanly used, it acts as a very useful and necessary guardian and caretaker.
