  2. Passage 14: Scientific knowledge has its dangers, but so has every great thing. Over and beyond the dangers with which it threatens the present, it opens up as nothing else can, the vision of a possible happy world; a world without poverty, without war, with little illness. Science, whatever unpleasant consequences it may have by the way, is in its very nature a liberator.


  3. 21. Which one of the following is the most important implication of the passage? (a) A happy world is a dream of science. (b) Science only can build a happy world, but it is also the only major threat. (c) A happy world is not possible without science. (d) A happy world is not at all possible with or without science.


  4. Answer. c


  5. Passage 15: The Arctic's vast reserves of fossil fuel, fish and minerals are now accessible for a longer period in a year. But unlike Antarctica, which is protected from exploitation by the Antarctic Treaty framed during the Cold War and is not subject to territorial claims by any country, there is no legal regime protecting the Arctic from industrialization, especially at a time when the world craves for more and more resources. The distinct possibility of ice-free summer has prompted countries with Arctic coastline to scramble for great chunks of the melting ocean.


  6. 22. Which one of the following is the most important implication of the passage? (a) India can have territorial claims in the Arctic territory and free access to its resources. (b) Melting of summer ice in the Arctic leads to changes in the geopolitics. (c) The Arctic region will solve the world's future problem of resource crunch. (d) The Arctic region has more resources than Antarctica.


  7. Answer. b
