【答案解析】[听力原文]15-17 Various kinds of nuclear weapons have been produced in the past few years by many countries. This is a new and a terrible development in the history of man. Very few events can be more frightful than a nuclear war. In a nuclear war, most of the world's population will be exterminated. (15[C])The few living Creatures that survive will be exposed to radiation or to electrical rays harmful to life. It has been said by scientists that many new diseases will be caused by radiation. (16[B])There will also be an acute shortage of food, for all the crops and stores will be poisoned by radiation. Most of the areas on which nuclear bombs have been dropped will be ruined. (17[A])Therefore the survivors of a nuclear war will be sick, hungry and homeless. It might be better; perhaps, to be killed in a nuclear war than to survive it. It would be better still for men to learn to live in peace with one another. If this can be achieved there will be no nuclear wars. 细节题。短文中说：生物体受爆炸后的放射物和射线的危害。这与选项[C]的说法一致。
