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?

The candidate’s ratings improved significantly as a result of the half-hour-long political advertisement.
Political advertisements have become increasingly influential in determining voters’ decisions at the polls.
Many people would appreciate the opportunity to become better acquainted with political candidates’ views on current political issues.
Most people who are interested in political issues watch television regularly.
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.

Answer:E

How to analyze? Thank you.

前面那一段话，陈述了一个事实，大部分观众不喜欢看长的广告。

后面举了一个例子，last year ，好多人turn into 这个channel，得出来一个结论，其实大多数人是喜欢看长的广告的。

通过好多人turn into这个channel推出那个结论，存在一个flaw，就是忽略了这些人是否会flow out。如果假定没有flow out才可以推出结论，因此，这个结论的assumption必定是说turn into channel的那些观众都会继续收看下去，没有换台。

也就是答案啦。其他选项根本不相关的。assumption的题目是需要建立conclusion与evidence之间的纽带，不相干的东西都是错误的
