PASSAGE-2The assault on the purity of the environment is the price that we pay for many of the benefits of modern technology. For the advantage of automotive transportation we pay a price in smog-induced diseases; for the powerful effects of new insecticides, we pay a price in dwindling wildlife and disturbances in the relation of living things and their surroundings; for nuclear power, we risk the biological hazards of radiation. By increasing agricultural production with fertilizers, we worsen water population.The highly developed nations of the world are not only the immediate beneficiaries of the good that technology can do, that are also the first victims of environmental diseases that technology breeds. In the past, the environmental effects which accompanied technological progress were restricted to a small ans relatively short time. the new hazards neither local nor brief. Modern air pollutions covers vast areas of continents: Radioactive fallout from the nuclear explosion is worldwide. Radioactive pollutants now on the earth surface will be found there for generations, and in case of Carbon-14, for thousands of years.1. The widespread use of insecticides has 1. reduced the number of wild animals 2. caused imbalance in the relationship between living beings and their environment 3. eliminated diseases by killing mosquitoes and flies 4. caused biological hazards2. The passage emphasis that modern technology 1. is an unmixed blessing 2. has caused serious hazards to life 3. has produced powerful chemicals 4. has benefited highly developed nations3. According to the passage the increasing use of fertilisers is responsible for1. abundance of food2. disturbance in the ecological system 3. water pollution 4. increase in diseases4. The harmful effects of modern technology are 1. widespread but short-lived 2. widespread and long-lasting 3. limited and long-lasting 4. severe but short-lived5. Radioactive pollutants 1. are limited in their effect 2. will infect the atmosphere for thousands of years 3. will be on the surface of earth for a very long time 4. will dissipate in short span of timePASSAGE-3It is to progress in the human sciences that we must look to undo the evils which have resulted from a knowledge of physical world hastily and superficially acquired by population unconscious of the changes in themselves that the new knowledge has imperative. The road to a happier world than any known in the past lies open before us if atavistic destructive passions can be kept in leash while the necessary adaptations are made. Fears are inevitable in time, but hopes are equally rational and far more likely to bear good fruit. We must learn to think rather less of the dangers to be avoided than of the good that will lie within our grasp if we can believe in it and let it dominate our thoughts. Science, whatever unpleasant consequences it may have by the way, is in its very nature a liberator, a liberator of bondage to physical nature and in time to come, a liberator from the weight of destructive passions. We are on the threshold of utter disaster or unprecedentely glorious achievement. No previous age has been fraught with problems so momentous; and it is to science that we must look to for a happy future.या उताऱ्यावर आधारित प्रश्न उद्याच्या अंकात प्रसिद्ध होतील.
