标题: 求助:GWD-10-Q15
好像CD这没有这道题目的讨论,所以我想请NN们帮忙解释一下,先谢谢啦
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 .
- many nonfunctioning satellites remain in orbit for years
- for satellites that have ceased to function, repairing them while they are in orbit would be prohibitively expensive
- there are no known previous instances of satellites’ having been exploded on purpose
- 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
- 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,我选的是D 我的理解是telescope observation与其他太空飞行器interfere的原因不在于和卫星相撞,在太空引爆卫星不能解决问题。那么就可以削弱。
另外,我类似complete the argument这样的逻辑题都做得不太好,有什么好的思路么?谢谢了

天文望远镜之所以不能很好的工作是因为debris的反射,大卫星的存在就等于是一种大的debris会反射,决定炸掉大卫星,但是炸掉大卫星会有很多的小碎片,这样会使得观察更加的困难
D怎么样使得天文望远镜如何能不受影响不是文章考虑的问题
文章问的是炸掉大卫星为什么是ill conceived、

感觉是一个weaken题,无关的选项都要排出

gonghao的解释非常好,我之前就是没有考虑到炸掉大卫星,会产生很多小碎片,而E选项里所说的急剧增加的小碎片就是炸掉大卫星所产生的。

Thank you.

该题我选的也是D,还是有些糊涂,D为什么说是无关选项呢, 文中说了the proposal recently been made to eliminate interference,也就是eliminate interference是目的,D说实现该目的的唯一手段是……,也就是文中的proposal不能实现该目的,从而驳斥。不知我这个思路哪有问题呀,求牛牛们指点一下,这道题困惑我好久好久了呀………!!

我的理解是填空题出现However,空中的内容应该与however前的内容直接相关,也就是要与原因和结果直接相关。而D选项与文中本身的因果关系无关,有点简单粗暴的直接反结论的意思。
不知道看懂了没。。。。有点绕o(>﹏<)o
