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?

A.
The candidate’s ratings improved significantly as a result of the half-hour-long political advertisement.

B.
Political advertisements have become increasingly influential in determining voters’ decisions at the polls.

C.
Many people would appreciate the opportunity to become better acquainted with political candidates’ views on current political issues.

D.
Most people who are interested in political issues watch television regularly.

E.
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.

为什么B不对呢？E即使开始几分钟不转台，节目那么长，不喜欢还是会转台的阿，为什么是前提呢？

B是无关吧。题中并没说人们看广告后就会选哪个candidate啊。虽然我觉得E中的first few minustes有点少了，但是也只能选了个相对靠谱的了啊...

请大家讨论

B选项无关。

E，可以取非验证其正确性。即，如果这些人在前几分钟换台的话我们就得不到many more people interested in watching lengthy televised political messages than was prviously thought这个结论。

假设题的最好的解决方法，如果在题干中有否定，就取非选项，看是否可以削弱结论。

谁来解释一下答案A为什么不对？
