To evaluate this argument, we need to consider which piece of information would be most relevant to assessing its strength or weaknesses. Let's analyze the argument and then consider each option:
The argument essentially states:
1. It was expected that increased computer use would lead to decreased TV viewing.
2. This expectation was based on the assumption that people don't have enough free time for both activities.
3. A survey showed that most people who increased their computer use did not change their TV viewing habits.
4. Therefore, the original assumption is false.
Now, let's look at each option:
(A) Whether a large majority of the survey respondents reported watching television regularly
This isn't particularly relevant. We're interested in the relationship between computer use and TV viewing, not just how many people watch TV.
(B) Whether the amount of time spent watching television is declining among people who rarely or never use computers
This doesn't directly address the argument, which is about people who are increasing their computer use.
(C) Whether the type of television programs a person watches tends to change as the amount of time spent per week using computers increases
While interesting, this doesn't address the core issue of time spent on each activity.
(D) Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers
This might be slightly relevant, but we're already told that the survey is about people who reported increasing computer use.
(E) Whether the survey respondents' reports of time spent using computers included time spent using computers at work
This is the most relevant option. Here's why:
1. The original assumption was about free time.
2. The survey results seem to contradict this assumption.
3. However, if the reported increase in computer use includes work time, it doesn't actually contradict the original assumption about free time.
If people are including work computer use in their responses, it doesn't necessarily mean they're using more of their free time on computers. This could explain why their TV viewing habits haven't changed - their free time allocation might not have changed as much as the survey initially suggests.
Therefore, option (E) would be the most useful to determine in order to evaluate the argument. It directly addresses a potential flaw in the survey's interpretation and its relevance to the original assumption about free time allocation.
