Which of the following most logically completes the argument?
The growing popularity of computer-based activities was widely predicted to result in a corresponding decline in television viewing. Recent studies have found that, in the United States, people who own computers watch, on average, significantly less television than people who do not own computers. In itself, however, this finding does very little to show that computer use tends to reduce television viewing time, since __________.
重心：玩电脑减少看电视时间
（做题时了省时间可以先不看问题问的是什么 选项只找和重心有关的）
A. many people who watch little or no television do not own a computer
和有没有电脑无关
B. even though most computer owners in the United States watch significantly less television than
the national average, some computer owners watch far more television than the national average
无关比较类（比较的对象一定要是文中的对象 显然文中没有提到过National average）
C.computer owners in the United States predominantly belong to demographic groups that
have long been known to spend less time watching television than the population as a whole does
对recent studies 的样本进行解释 有关！
D. many computer owners in the United States have enough leisure time that spending significant amounts of time on the computer still leaves ample time for watching television
方向错（文章说的一增一减 他说的是两个都增）significant ample同方向
E. many people use their computers primarily for tasks such as correspondence that can be done more rapidly on the computer, and doing so leaves more leisure time for watching television
和用电脑做什么无关

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 change in time spent watching television.
In order to evaluate the argument, it would be most useful to determine which of the following?
重心：玩电脑减少看电视时间A. Whether the survey collected information about the amount of
money respondents spent on free-time media use
文中没有提到钱选项说Money 无关！
B. Whether the amount of time spent watching television is declining among people who report that they rarely or never use computers
有绝对的次的选项一般不对！
C. Whether the type of television programs a person watches tends to change as the amount of time spent per week using computers increases
和电视节目类型无关
D. Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers
在说用电脑时间的问题有关保留
E. Whether the survey respondents’ reports of time spent using computers included time spent using computers at work
在说用电脑时间的问题有关保留
DE抉择谁更贴近重心？D说computer owners in the survey E说the survey respondents’
显然E更贴近中重心因为原文中根本没提到computer owners in the survey见绿色部分
