标题: 求比较两道CR，prep里用电脑影响看电视时间的

第一题：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

第二题：

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 charge in time spent watching television.

Which of the following would it 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 change as the amount of time spent per week using computers 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

受第二题影响，我第一题选的E，求问两道题assumption的差异和解题思路，谢谢！！

Q1
P1：电脑的使用可能会导致电视使用的减少；
P2：研究发现有电脑的人比起没有电脑的人，的确看电视的时间更少；
C：电脑的使用对电视的使用没影响；
分析：P2中发现有电脑的人看电视时间少，那么要推出结论，就得说明看电视时间少的原因不是因为电脑的存在，而是其他因素，比如这些人所处的年龄阶段本来就不喜欢看电视；
A：讨论的是有电脑的人，无关；
B：客观陈述有电脑的人收看电视的习惯，无关；
C:正确；他因；
D：无关；讨论的是电脑的使用是否影响电视的使用，不是有木有足够时间的问题；
E：使用电脑的用途，无关；

Q2，
P1：人们认为电脑广泛使用使得电视的使用下降；
P2：但最近的调查显示很大一部分人看电视的时间并未减少，随着他们使用电脑的时间的增加；
C：电脑的使用对电视使用没影响：
分析：评价，
A；被调查者是否经常收看电视买无关；
B：不适用电脑的人，out of scope;
C: 电视节目的类型，out of scope;
D：题中已经说了使用电脑的时间是在增加；
E：被调查者使用电脑的时间是否包含在工作内；如果是，那么结论就不成立；如果不是，那么成立；

还有一个关于第二题选项A的问题
Whether a large majority of the survey respondents reported watching television regularly

原文中说的是：a very large majority，选项A中说：a large majority。
这两个算是一个范围么？
