Read the following passage carefully and answer the questions that follow.

Just as some men like to play football or cricket, so some men like to climb mountains. This is often very difficult, for mountains are not just big hills. Paths are usually very steep. Some mountain sides are straight up and down, so that it may take many hours to climb as little as one hundred feet. There is always the danger that you may fall off and be killed or injured. Men talk about conquering a mountain. It is a wonderful feeling to reach the top of a mountain after climbing for hours and maybe, even for days. You look down and see the whole country below you. You feel god-like. Two Italian prisoners of war escaped from a prison camp in Kenya during the war. They did not try to return to their own country, for they knew it was impossible. Instead, they climbed to the top of Mount Kenya, and then they came down again and gave themselves up. They had wanted to get that feeling of freedom that one has, after climbing a difficult mountain.
