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 .

(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

题目类型：

complete the argument

题目翻译：

围绕地球运转的人造卫星的数量比小碎片的数量要多的多。人造卫星对太空望远镜观测的影响又非常的大。因为很多的人造卫星已经停止工作了，最近有人提出要对这些人造卫星实行人工爆破，以达到减少对观测影响的目的。这种想法是不科学的。

解题思路：

证明这种做法并不能减少对太空望远镜观测的影响。

逐项分析：

A、许多不工作的人造卫星仍然在轨道上运转数年。正是因为此，我们才要对其进行爆破。

B、对于已经停止工作的卫星，在轨道上对其进行修复的成本很高。无关项。

C、以前没有人工爆破卫星的先例。无关项。以前没有不代表以后没有。

D、想让太空望远镜观测无干扰的唯一办法是使用发射到离地球很远的轨道中的太空望远镜。无关项。

E、正确选项。对人造卫星进行爆破会产生很多的小碎片，而地球周围过多的小碎片会给观测带来不好的影响。

正确选项：

E
