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 _______. 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

D选项说唯一的方法是发射t到更远的轨道，因此排除了题目说的爆炸t 这一个提议，所以我认为是weaken
F 选项说大量小碎片会阻碍远距离的观察，但是原文并没有说爆炸t会产生小碎片，所以我觉得不过
综上所述，我选d
但是答案是e

常识告诉我爆炸会产生碎片。。。可惜题里没说。。。
D会不会扯太远了？

逻辑题里的信息是不是没有多余的？
原文虽然没有讲爆炸会产生碎片。但是起码讲到了碎片。
是不是可以根据原文信息都有效，判断出爆炸和碎片有关系，否则将碎片干嘛。

ps.逻辑题里的信息是不是没有多余的？??
