标题: prep逻辑。。。我郁闷的说。。。
89. (29334-!-item-!-188;#058&003870)

Which of the following most logically completes the argument?
The growing popularity of computer-based activities was widely predicted to result in a corresponding decline in television viewing. Recent studies have found that, in the United States, people who own computers watch, on average, significantly less television than people who do not own computers. In itself, however, this finding does very little to show that computer use tends to reduce television viewing time, since __________.
A. many people who watch little or no television do not own a computer
B. even though most computer owners in the United States watch significantly less television than the national average, some computer owners watch far more television than the national average
C. computer owners in the United States predominantly belong to demographic groups that have long been known to spend less time watching television than the population as a whole does
D. many computer owners in the United States have enough leisure time that spending significant amounts of time on the computer still leaves ample time for watching television
E. many people use their computers primarily for tasks such as correspondence that can be done more rapidly on the computer, and doing so leaves more leisure time for watching television

为什么要选C，我觉得D和E都比C好啊？？？？？

这是GMAT逻辑的一个典型套路，即不直接对findings取非进行攻击，而是攻击样本的代表性。GMAC认为相比较直接攻击，这更有逻辑性。AA写作里面也常用到这个logical fallacy

说own computer 引起 less television，题目说要我们 weaken the argument.也就是说不是 own computer 引起的 less television，那么这时候我们要新引入一个原因来证明它才是引起的 less television。
C 选项说 own computer 的人大多数都是属于一种人群，那么说明不是是否拥有 computer来 less television，而是这样的一个特定人群（比如年轻人）导致 less television。
DE 选项都强调 own computer 的人是有时间来看电视的，但是依然没解释为什么people who own computers watch, on average, significantly less television than people who do not own computers。也没引入新的原因去取代own computer 这个原因来导致 less television。

希望我讲明白了啊~呵呵

这里不是在攻击样本的代表性，own computer 的人大多属于一个特定人群是一个事实，不是说 own computer的人大多是这个人群就不应该调查own computer 的人，恰恰是这些被调查的人大多数是一个特定的人群才说明了不是 own computer 导致 less television 而是这个样的人群才导致less television。这根代表性无关。

样本本身的倾向影响结果的准确性，这样解释行了吧………悲剧地被攻击字眼 …

都没说到点子上去。。。e说明了使用电脑可能增加看电视的时间，但是题目问的是“this finding does very little to show...”，请注意，这里说的是“this finding”，e的内容跟this finding毫无关系

DE都无关吧。。题目问的是整个人的看电视时间。。
