The format of network television news programs generally allows advocates of a point of view only 30 seconds to convey their message. Consequently, regular watchers become accustomed to thinking of issues in terms only of slogans and catch phrases, and so the expectation of careful discussion of public issues gradually disappears from their awareness. The format of newspaper stories, on the other hand, leads readers to pursue details of stories headed by the most important facts and so has the opposite effect on regular readers—that of maintaining the expectation of careful discussion of public issues. Therefore, in contrast to regular newspaper reading, regular watching of network television news programs increases the tendency to think of public issues in oversimplified terms.

19. Which one of the following, if true, most seriously weakens the argument?
(A) Regular watchers of network television news programs are much more likely than other people to be habitual readers of newspapers.
(B) Including any 30-second quotations from proponents of diverse views, the total amount of time devoted to a single topic on regular network television news programs averages less than one and a half minutes.
(C) The format of network television news programs does not include roundtable discussion of issues among informed proponents of diverse views.
(D) Television news reports tend to devote equal time to discussion of opposing views.
(E) People who watch the most television, measured in average number of hours of watching per week, tend not to be regular readers of newspapers.

排除法，可以得到A。但是我一直疑惑，它是如何结论的呢？

我之所以产生疑惑，感觉上和mindfree是一样的，因为题目并不是说爱看电视的人思维简单化，而是说，经常看电视可以让人思维简单化，所以即使经常看电视的人思维还是非常复杂完整，也并不能真正的削弱文章的结论，况且，文章中也没有说看报的人思维就一定完整复杂，只是说看报可能有这个效果，因此，并不是程度的问题，而是隔靴搔痒的问题，着眼点不同。这个解释还是不通。只不过在所有的选项中，只有这个沾边罢了。

大家继续讨论。

我觉得这个答案只能是无奈之选，我们从答案中也无法明确看报纸到底是看电视的必然后果。如果可以得出看电视必然导致爱看报纸，则结论被削弱。毕竟其它的选项不沾边。

是否只要提供的信息暗示一种可能性，比如一种和结论不同（而非对抗）的可能性就可以认为是削弱呢？我一直也认为，削弱是使得结论成立的可能降低，并非是一定要完全否定结论，但是在这个题目中，其结论也是增加一种可能和倾向，它并未排除相反的状况，所以很难说，结论和选项存在不同或冲突，因此也并不能降低结论成立的可能性。
