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.
(C) Few of the early buyers of video recorders raised any complaints about performance aspects of the new product.
(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.
(E) In a shrinking market, competition always intensifies and marginal businesses fail.

答案：D，我觉得D是加强啊？请问D是怎么削弱的呢？难道是提出他因？如果是他因削弱的话，E更有可能是他因。怎么回事呢？

9. Which of the following best completes the passage below?
The computer industry’s estimate that it loses millions of dollars when users illegally copy programs without paying for them is greatly exaggerated. Most of the illegal copying is done by people with no serious interest in the programs. Thus, the loss to the industry is much smaller than estimated because
(A) many users who illegally copy programs never find any use for them
(B) most of the illegally copied programs would not be purchased even if purchasing them were the only way to obtain them
(C) even if the computer industry received all the revenue it claims to be losing, it would still be experiencing financial difficulties
(D) the total market value of all illegal copies is low in comparison to the total revenue of the computer industry
(E) the number of programs that are frequently copied illegally is low in comparison to the number of programs available for sale

答案：B，我觉得B，D，E都可行。有什么区别吗？我完成句子题做得不好，经常会觉得有几个选项都可以。有什么好办法吗？

谢谢。

回答第一题，D提出的不是他因。因为文中的推论都是基于第一句话，这个事实是作者得出此后结论的论据和基础，D恰恰对这一事实的诠释提出了新的见解，即早买的一般都是那些容易喜新厌旧的人，换言，以后买的人，不会6个月就烦了，所以从根本上动摇了文章的理论基础。
回答第二题，DE都讲了数字比例的问题，这只是说估计的损失占全部市场价值的比例不大，并不能支持，实际数字比估计的数字小这一结论。
希望有用

同意cranberry的观点。
就第二道题补充一点，原文题眼在people with no serious interest in the programs。答案就是要求进一步解释这句话，B可以接受。

以下是引用cranberry在2003-4-13 16:47:00的发言：

GMAT的逻辑讲的是傻子原则
而D中:,即早买的一般都是那些容易喜新厌旧的人===>以后买的人，不会6个月就烦了，所以从根本上动摇了文章的理论基础。

这个推论能推出吗?谢谢.

文章的立论就在于认为拥有了产品六个月后人们都烦了不再租录影带，那么一旦大家都买了，超过六个月后，就没人租了，进而提供录影带租赁的行业就危险了，D是说，文章所依据的关于现在那些6个月就烦了的，都是喜新厌旧的人，并不能说明所有人都是这样的，因此，文章的支点就没有了。

一个很弱的问题，拥有了产品，即购买了录像带，怎么又要去租呢？？
