OG12 39 A选项

og12-39
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 suffi cient 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
(answerE)

我理解E为什么正确，但是A好像也是正确的：
题目论据是由于调查发现大多数使用电脑时间增加的调查者看电视时间没有变化（report no change in time spent watching television）
而A选项的问题，如果使用电脑时间增加的调查者根本不看电视，那么他们看电视时间当然不可能再下降了。因此会导致题目论据的样本选择有问题。因此A选项也是个关键问题？
