38. GWD21-Q38:

Because it was long thought that few people would watch lengthy televised political messages, most televised political advertisements, like commercial advertisements, took the form of short messages.  Last year, however, one candidate produced a half-hour-long advertisement.  During the half hour the advertisement was aired, a substantial portion of the viewing public tuned into the advertisement.  Clearly, then, many more people are interested in watching lengthy televised political messages than was previously thought.

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.

答案为什么会是B啊? 会不会我脑袋坏掉拉?

   Answer:

这题ANS:E才对!!!必须要有个前提假设是大多数观众在转到the candidate’s half-hour-long advertisement 的时候不会转台的前提假设才得支持结论:many more people are interested in watching lengthy televised political messages

请指教

没看准题目，我一开始选了C，重新看了题目才发现是相反的，削弱结论的。

我觉得E对的有道理，evidence:半个小时的节目里，很大比例的观众tuned into 这个

广告；conclusion:其实喜欢看lengthy televised political messages的观众要比想

象的多很多。

这里有一个GAP：很多观众坚持在半小时里watch the advertisement才能推出来他们

喜欢看这种ad.

注意这里根evidence表述的差别，应该是坚持watch而不是tune into，这个词是解题

关键。

E选项，观众tuned into the ad &并且没有在最初的几分钟过后就换了频道（这里才

能说明他们是喜欢看而不是碰巧看看），这样才能得出题目的结论。

B完全是无关项引入，如果这个项成立，那么就得又多一个假设：喜欢看long ads的观

众都热心voting。

大家都来讨论讨论阿，别沉！
