38. GWD21-Q38:

Which of the following is an assumption on which the argument depends?

1. The candidate’s ratings improved significantly as a result of the half-hour-long political advertisement.
2. Political advertisements have become increasingly influential in determining voters’ decisions at the polls.
3. Many people would appreciate the opportunity to become better acquainted with political candidates’ views on current political issues.
4. Most people who are interested in political issues watch television regularly.
5. Most of the viewers who tuned in to the candidate’s half-hour-long advertisement last year did not change channels after the first few minutes.

答案是E，为什么呢？虽然我能猜出来时E但是却选项不明白是什么意思以及原因，请大家指点

E： 大多数收看了这个长广告的观众不是只看了几分钟就换台了。

assumption题，用＂取否＂：
E的否命题是：大多数观众才看了几分钟就换台了。  那么说明大多数观众并不对这个长

广告感兴趣，从而直接weaken原结论＂many more people are interested in watching

lengthy televised political messages than was previously thought＂。

所以E是assumption。

其他选项取否都没有影响。
