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
答案是C
The growing popularity of computer-based activities was widely expected to result in a decline in television viewing, since it had been assumed that people lack sufficient free time to maintain current television-viewing levels while spending increasing amounts of free time on the computer.  That assumption, however, is evidently false: in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computers report no change in time spent watching television.

In order to evaluate the argument, it would be most useful to determine which of the following?
A. Whether the survey collected information about the amount of money respondents spent on free-time media use
B. Whether the amount of time spent watching television is declining among people who report that they rarely or never use computers
C. Whether the type of television programs a person watches tends to change as the amount of time spent per week using computers increases
D. Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers
E. Whether the survey respondents’ reports of time spent using computers included time spent using computers at work

答案是E，这道题不大理解思路

还有这两道题有什么区别？？

第一题,其实是paradox，要使矛盾的现象不矛盾为正确选项。第二题，题干中的重点词其实是free time.

这应该是枚举推理吧 考察的明显是样本能不能代表总体

这个答案好，那第一题讲就是问题说的是， 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.推导不出computer use tends to reduce TV viewing time。后面的since相当于就是为什么推导不出，而不是问你computer use会reduce TV viewing time这个对不对。也就是前面的p是成立的，然后问你这么推导行不行。

虽然楼主这样做题的确很快，但是我认为你所说的computer owners in survey 和 survey respondents'的差别我觉得并不能判断出这道题的对错，因为差别微乎其微，且原文没有提到是否respondents都是computerowner的问题。我认为应该从D：探讨的是用电脑时间会不会上升，E：探讨的是是不是包含工作时间，来判断。因为题目的核心是休闲时间中用电脑的时间挤占了看电视时间，如果包含工作时间则无法说明休闲时间的情况。而用电脑是否上升，如果上升也和是否休闲时间挤占看电视时间无关。请楼主指教！！
