GWD-10-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 recently been made to eliminate interference from nonfunctioning satellites by exploding them in space. This proposal, however, is ill conceived, since     .

1. many nonfunctioning satellites remain in orbit for years

2. for satellites that have ceased to function, repairing them while they are in orbit would be prohibitively expensive

3. there are no known previous instances of satellites’ having been exploded on purpose

4. 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

5. 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

填空题最晕菜：（我根本无法分辨D，E，觉得都是可以沿着原文说下去的。为什么有人说D无关啊？？？

题目说的是：虽然大的人造卫星跟大量的空间小碎片相比是小的，但是他们仍然严重影响了望远镜观察。因此应该把没用的卫星炸掉。

但是，这是不对的。因为。。。。。

E说，炸掉后的碎片更会严重影响观察。这里直接相关亚。而D说观察清楚无障碍的唯一方法是把望远镜发射到高的轨道。明显无关嘛。

MM，填空要注意题目说的重点。

哦，谢谢哦，理解错D的意思了

另外，追问一句，是不是答案中有only  most之类极端的词都不好的？

如果时间紧张的情况下要猜一个答案，是不是就排除带有这些词的答案？

或者象上面一下，最后两个答案无法选择，就只能这么选了。

没办法，还是十来天就考了……
