39.
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.
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 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

老题，但是这样题在考场上，我肯定瞎选了。 求做题思路。

那么 用电脑 频率的提升 并 不影响 看电视的时间~
