Read the given passage carefully and answer the questions given after the passage:

1. Often, we passionately pursue matters that in the future appear to be contradictory to our real intention or nature; and triumph is followed by remorse or regret. There are numerous examples of such a trend in the annals of history and contemporary life.
2. Alfred Nobel was the son of Immanuel Nobel, an inventor who experimented extensively with explosives. Alfred too carried out research and experiments with a large range of chemicals; he found new methods to blast rocks for the construction of roads and bridges; he was engaged in the development of technology and different weapons; his life revolved around rockets and cannons and gun powder. The ingenuity of the scientist brought him enough wealth to buy the Bofors armament plant in Sweden.
3.  Paradoxically, Nobel's life was a busy one yet he was lonely; and as he grew older, he began suffering from guilt of having invented the dynamite that was being used for destructive purposes. He set aside a huge part of his wealth to institute Nobel Prizes. Besides honouring men and women for their extraordinary achievements in physics, chemistry, medicine and literature, he wished to honour people who worked for the promotion of peace.
4. It's strange that the very man whose name was closely connected with explosives and inventions that helped in waging wars willed a large part of his earnings for the people who work for the promotion of peace and the benefit of mankind. The Nobel Peace Prize is intended f or a person who has accomplished the best work for fraternity among nations, for abolition or reduction of war and for promotion of peace.
5. Another example that comes to one's mind is that of Albert Einstein. In 1939, fearing that the Nazis would win the race to build the world's first atomic bomb, Einstein urged President Franklin D Roosevelt to launch an American programme on nuclear research. The matter was considered and a project called the Manhattan Project was initiated. The project involved intense nuclear research the construction of the world's first atomic bomb. All this while, Einstein had the impression that the bomb would be used to protect the world from the Nazis. But in 1945, when Hiroshima was bombed to end World War II, Einstein was deeply grieved and he regretted his endorsement of the need for nuclear research.
6. He also stated that had he known that the Germans would be unsuccessful in making the atomic bomb, he would have probably never recommended making one. In 1947, Einstein began working for the cause of disarmament. But, Einstein's name still continues to be linked with the bomb. Man's fluctuating thoughts, changing opinions, varying opportunities keep the mind in a state of flux. Hence, the paradox of life: its certain t hat nothing is certain in life.
