标题: [求助]T-9-Q18

T-9-Q18.

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 computer report no change in time spent watching television.

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

Whether a large majority of the survey respondents reported watching television regularly
Whether the amount of time spent watching television is declining among people who report that they rarely or never use computers
Whether the type of television programs a person watches tends to changes as the amount of time spent per week using computer increases
Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers
Whether the survey respondents’ reports of time spent using computers included time spent using computers at work.

不明白为什么选E。觉得这个应该是无关选项。

assumption中有free time这个概念，而反驳观点中没有这个时间概念。

我们现在需要知道是不是反驳观点中的那个试验数据中，包含了在工作中使用计算机的时间，如果包括了，这个实验数据就无效了。
