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？

Regular看电视新闻的人 比其他人更有可能是habitual报纸读者。

文章结论说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.其实是把 regular newspaper reading的人群和regular watching of network television news programs的人群完全对立起来，看成exclusive的了。

选项A正是提出了两个人群的这种overlap的情况，所以weaken。

c为什么不对？

mindfree

Interestingly, I eliminate A right away and I still don't like it. Even when there is an overlap between TV news watcher and habitual newspaper reader, watching TV news can still increase the tendency, while the newspaper reading decreases it. A will perfectly weakens an argument that people who watch TV news tend to ..., but not the conclusion in this question.

当两类人重叠时，结论一类人比另一类人怎样的说服力就减弱。所以WEAKEN。WEAKEN的本质不需要充分性，只要程度发生变化就可以，SUPPORT也一样。

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。

我觉得这个问题可以用集合来解释；

regular watching of network television news programs的人看成集合a，regular newspaper reading的人看成集合b，原文的结论是：和集合b的人比较，集合a的人增加了新闻热点简单思考的趋势。

答案A说集合a和集合b相交，有可能出现集合a属于集合b，这种情况下集合a的人会怎样，原文没有说，但是此时结论不再成立。

经常看电视造成的思维简单化，可以被经常看报纸弥补，所以weaken了“看电视就增加了思维简单化的这个趋势”这个结论。

原文结论：相对于常看报纸，常看电视新闻使人更趋于看问题简单化（讨论的问题是相比常看报纸，常看电视新闻是否会使人看问题简单化）。为了证明这个结论，原文提出两个证据：一是常看电视新闻，使人习惯于想问题简单化。二是相反，常看报纸作用相反（has the opposite effect ， on the other hand）（使人看问题不会简单化）。A说常看电视新闻的人比其他人更可能常看报纸。其隐含的意思是常看电视新闻常会诱使人再看报纸，从而不会简单的看问题，这是一系列的动作，其源头是常看电视新闻。所以，常看电视新闻由于它能使人也常看报纸，从而不会简单的看问题，使原文的结论说常看电视会使人趋于看问题简单化受到怀疑。其实原文是在讨论做一件事的效果，原文的WEAKEN方式为：看一件事的效果不能孤立来看，不但要看它本身的效果，还要看他的引起的其他效果。这样才能全面比较两件事，否则是片面的。

这些是你的个人推断，我觉得并不可靠，个人感觉从原文中我们只能得到的信息是这些人看电视新闻的人又看了报纸结果会怎样，这个结果我们无法判断，但很明显原文的结论此时遭到了置疑。
