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 maintian current television-viewing levels while spending increasing amounts of free time on the computer. That assumption, however, is eveidently 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 amout of money respondents spent on free-time media use

B. whether the amount of time spent watching television if declining among people who report that they rarely or never use compters

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E，逻辑是什么呢。。我选的D

D是無關, 因為問題不在於是否多了人去多用電腦, 問題是在於人多用電腦是否會令到人減少看電視.
If E is true, 那麼那個argument就削弱, 因為人不是在他們free time中多用了電腦, 只是在上班時多用了電腦 (weaken: survey不準)
If E is false, 那麼那個argument就被加強, 因為人不是在他們在上班時多用了電腦, 所以必定在其中時間中多用了電腦 (strengthen: survey準)

我就是按字面理解去看的

花在电脑上的时间的上升其实不代表看电视时间的减少，因为可以边用电脑边看电视啊

事实上我也是这个样子的。吼吼
