请教下面这道题目的分析：谢谢

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 charge in time spent watching television.

 

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

 

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

ABC无关，DE之间我有点犹豫，D是从respondents who report increasing time spent per week using computers 这个survey的对象的数量上来value，如果这个数量不大的话， a very large majority 就也不会大了，E是从per week， free time，computer-based activities 等字眼着手，如果这些increasing time spent per week using computers 的不是free time的，就不会影响 time spent watching television，但是这样的话，就和原假设不冲突了，是另外一码事了

我还是选D,请NN指教！

好像d和e的分歧就在：d怀疑的是在mail survay中样本的质量；e怀疑的是spending free time上，我觉得e在题目中给的比较清楚，倾向选e。明白人继续讨论~
