Q15:
Which of the following most logically completes the argument below?
Although the number of large artificial satellites orbiting the Earth is small compared to the number of small pieces of debris in orbit, the large satellites interfere more seriously with telescope observations because of the strong reflections they produce. Because many of those large satellites have ceased to function, the proposal has recently been made to eliminate interference from nonfunctioning satellites by exploding them in space. This proposal, however, is ill conceived, since _______.
答案说是E
然而,为什么D不对啊???
求助一下~~~~GWD第一套 15题
这个complete我觉得是weaken的思路。原文说大的卫星对于观测有干扰,因此要通过爆破那些没有用的大卫星来减少干扰。题目问的是,为什么这个方法是不好的。weaken方向是爆炸不能减少干扰,或者爆炸以后会增加干扰。
爆炸会导致很多碎片,如果碎片增多会使得观测无法进行,那么就不能达到原来的目的--即减少对观测的干扰。也就是E说的内容。
D的意思是减少干扰的唯一方法是到一个至高点去观察。如果D正确的话,爆炸就不影响干扰了,因为爆炸以后还是可以找一个至高点去观察的。那样就不能得出结论说,爆炸的这个方法是有问题的,反而有点support原文了。
我是这么想的,不知道讲的是否清楚。
