XDF发的一道模考题
The growing popularity of computer-based activities as widely expected ro result in a decline in television viewing, since it had ben assumed that people lack sufficient free time to maintain current television-viweing levels while spending increasing amounts of free time on the computer. That assumption, however, is evidently false: ina recent mail survey concerning mediause, a very large majority of respondents who report increasing time spent per week using computers report no charge in time spent watching television.

Which of the following would it be most useful to determine in order to evaluate the argument?

A. Whether a large majority of the survey respondents reported watching television regularly?
B. Whether the amount of time spent watching television is declining among people who report that they rarely or never use conputer?
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，求高人讲解啊！谢谢！

OG上的 这种题目就是看到了问一问自己成了与否是否改变conclusion
E项，如果是包括了time spent using computers at work那么题目刚开始的那个argument还是有点valid的 因为这个time spent using computers 并非free time；如果并不包括time spent using computers at work，那么argument有问题
