Read the passage and answer the questions that follow:

Various kinds of nuclear weapons have been produced in the past few years by many countries. There is a new and terrible development in the history of man. Very few events can be more frightful than nuclear war. In a nuclear war, most of the world's population will be exterminated. 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. There will also be an acute shortage of food. Most of the areas on which nuclear bombs have been dropped have been ruined. 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.
