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 recently been made to eliminate interference from nonfunctioning satellites by exploding them in space. This proposal, however, is ill conceived, since.
A.many nonfunctioning satellites remain in orbit for years
B.for satellites that have ceased to function, repairing them while they are in orbit would be prohibitively expensive
C.there are no known previous instances of satellites’ having been exploded on purpose
D.the only way to make telescope observations without any interference from debris in orbit is to use telescopes launched into extremely high orbits around the Earth
E.！a greatly increased number of small particles in Earth’s orbit would result in a blanket of reflections that would make certain valuable telescope observations impossible
答案是E，为什么，我不懂耶，文章中并没有说会有 a greatly increased number of small particles呀 作者: nakig 时间: 2010-5-8 18:37
文章最后一句就是说exploding them啊...把大的卫星炸了，就会变成小碎片，小碎片的反射影响比整个卫星的更大。作者: bonnie0715 时间: 2010-5-8 18:59
仅管小碎片比达卫多很多，但是大卫星截断更多telescope observation，因为它们reflection能力很Strong。所以坏了就炸掉它们好了，反正小碎片不顶用。 E，小碎片多了会勾结起来的嘛，形成一个大blanket反射能力超级无敌巨大，大卫星就不能跟他们抗衡了嘛
