[求助]T9-Q18,A 为啥错？

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?

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 changes as the amount
of time spent per week using computer 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.

A答案中被调查的人是本来就不怎么看电视的人，那么对他们调查的结果不足以对原来的假设构成反驳，不是主推论中的有效证据。

选E

注意题干中一句话 

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.

前面说的是在free time用computer,后面的论据是说time

所以才有了E选项,到底论据中的time包括不包括work time

赫赫,细节,还是要仔细读题

这个题就和那个海鸟题一样,要注意到sharp increase,很小的细节
