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?
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。
