Correct Answer: E
Explanation:
Option A : The argument is concerned with the change in the amount of television watched bythose whose computer use increased, so whether the survey's respondents reported watching television regularly is irrelevant.
Option B : The argument is concerned with the change in the amount of television watched by those whose computer use has increased, so it does not matter whether the amount of time spent watching television among people who do not use computers is declining, remaining the same, or increasing.
Option C : The argument is concerned with the amount of television watched by those whose computer use has increased, not the type of television programs such a person does or does not watch.
Option D : The argument here isconcerned with people who report spending increasing amounts of time on
the computer; what computer owners do is a separate question.
Option E : Correct. This statement properly identifies something that would be useful to know in evaluating the argument: whether the survey data included time spent using computers at workâif it did, this would make the data misleading as evidence for the argument's conclusion.
The correct answer is E.
