问题     The difficulties that would have to be encountered by anyone who attempted to explore the Moon would be incomparably greater than those that have to be faced in the endeavor to reach the summit of Mount Jolmo Lungma. In two respects only would the lunar explorer have the advantage. In the first place movement would be less fatiguing because the gravitational pull of the Moon is not very great, the weight of the Moon being only about one - eightieth of that of the Earth. If the Moon had an atmosphere like that of the Earth, a man playing golf on the Moon would find that he could drive his ball for a mile without much difficulty. The second advantage the lunar explorer would have over the climbers on Mount Jolmo Lungma would be the absence of strong wind to contend against. The Moon having no atmosphere, there can be no wind nor, of course, can there be any noise, for sound is carried by the air. The Moon is a world that is completely still and where utter silence prevails.
It can be inferred from the passage that______.
选项 A、the gravity on the earth is 80 times as big as that on the moon
B、the weight of the earth equals the weight of 18 moons
C、a stone can be thrown far away very easily on the moon
D、the moon is a good place to play golf
答案A
解析 参阅第三句后半部分，月球重量是地球的八十分之一，因此地球对人的引力就是月球的八十倍。
