[单项选择]We all know that it is possible for ordinary people to make their homes on the equator (赤道), although often they may feel uncomfortably hot there. Millions do it. But as for the North Pole (北极)--we know that it is not only a dangerously cold place, but that people like you and me would find it quite impossible to live there. At the present time only the scientists and explorers can do so, and they use special equipment. Men had been traveling across and around the equator on wheels, on their feet or in ships for thousands of years; but only a few men, with great difficulty and in very recent time, have ever crossed the ice to the North Pole. So it may surprise you to learn that, when traveling by air, it is really safer to fly over the North Pole than over the equator. Of course, this is not true about landings in the polar region (which passenger aeroplanes do not make), but the weather, if we are flying at a height of 5000 meters above the Pole, is a delight. At 4 000 meters and More
A. in warm air
B. in cold air
C. when it reaches the polar region
D. only when the clouds are down low
