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. At the beginning of the half-hour slot a substantial portion of the viewing public had tuned in to that station. Clearly, then, many more people are interested in lengthy televised political messages than was previously thought.


Which of the following, if true, most seriously weakens the argument?


A. The candidate who produced the half-hour-long advertisement did not win election at the polls.
B. The half-hour-long advertisement was widely publicized before it was broadcast.
C. The half-hour-long advertisement was aired during a time slot normally taken by one of the most popular prime-time shows.
D. Most short political advertisements are aired during a wide range of programs in order to reach a broad spectrum of viewers.
E. In general a regular-length television program that features debate about current political issues depends for its appeal on the personal qualities of the program's moderator.

c: 选项里没有明确说明这个popular prime-time shows是不是本来应该在half-hour-long的ad的这个台播出啊？如果是，确实可以weaken，可如果是在其他台播，岂不是说明人们宁可不看popular show也要看这个ad，恰恰strenghen了结论啊？

我的逻辑在哪出问题了，求NN解答！！
