标题: 大全-2-15-->携隐修改标题（大全Test2-15, 看了讨论觉得还是疑惑）

15. Six months or so after getting a video recorder, many early buyers apparently lost interest in obtaining videos to watch on it. The trade of businesses selling and renting videos is still buoyant, because the number of homes with video recorders is still growing. But clearly, once the market for video recorders is saturated, businesses distributing videos face hard times.

Which of the following, if true, would most seriously weaken the conclusion above?

(A) The market for video recorders would not be considered saturated until there was one in 80 percent of homes.

(B) Among the items handled by video distributors are many films specifically produced as video features.

(D) The early buyers of a novel product are always people who are quick to acquire novelties, but also often as quick to tire of them.（D）

(E) In a shrinking market, competition always intensifies and marginal businesses fail.

这题除了D以外其它的都错的厉害, 但是我实在觉得D不是个好答案, 前面的讨论意思是"D说明了early buyer是喜新厌旧的, 言外之意old buyer不会".

但我觉得D说明了early buyer喜新厌旧只是原文的复述, 没有任何理由可以推断出old buyer不会啊! 既然推不出, 用如何去weaken结论? 请指教, 谢谢.

D means that the old buyers will throw away their old video recorders and buy new ones, and then they will try to get videos again for their new recorders, which will boom the business.

题干的逻辑是，因为前期的很多buyer出现了apparently lost interest in obtaining videos to watch on it的情况，所以得出结论说，这个business会最终遇到困境。

这样的逻辑是以偏概全，最开始的客户不能代表所有的客户的情况。在A＝》B中直接攻击A的代表性，所以就weak了。

奇怪,看了所有讨论,我怎么也是和2楼的一样.第一感觉就是:正因为喜新厌旧,所以这些early buyer 会不停的买新的,所以市场永远不会饱和.

关于这些early buyer的代表性,D并没有指出这些人就是少数啊.
