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 __________.

A. many people who watch little or no television do not own a computer

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

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

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

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

Answer: C

My Question: Why not B?

这道题我做的时候也选错了，根据7宗罪，就说明这个survey不符合random choose 或者其他，C选项正好就是这个

B选项呢，个体攻击群体~~似乎没有什么意义吧~~

我是这么认为的~~

Answer: C

My Question: Why not B?

补足题

原文说电脑活动多导致看电视少。研究发现有电脑的人比没电脑的人看电视少。但这无助于解释用电脑就少看电视，因为什么？

看选项：

A很多不看电视的人没电脑，无关

B即使MOST电脑用户看电视少于平均，有些电脑用户比平均看得多，太扯了，任何题目这样的选项都得杀

C指出统计谬误demographic fallacy，看着就舒服

DE，随便看看吧

带着挑错的眼光很快发现:

DE有什么leisure time这种没提过的东西

意思都不进脑子，直接干掉

C吧

错就错了

PACE为王
