大全-Ⅰ-7

大全-Ⅰ-7.    Whenever a major airplane accident occurs, there is a dramatic increase in the number of airplane mishaps reported, a phenomenon that may last for as long as a few months after the accident. Airline officials assert that the publicity given the gruesomeness of major airplane accidents focuses media attention on the airline industry and the increase in the number of reported accidents is caused by an increase in the number of news sources covering airline accident, not by an increase in the number of accidents.

Which of the following, if true, would seriously weaken the assertions of the airline officials?

(A) The publicity surrounding airline accidents is largely limited to the country in which the crash occurred.

(B) Airline accidents tend to occur far more often during certain peak travel months.

(C) News organizations do not have any guidelines to help them decide how severe or how close an accident must be for it to receive coverage.

(D) Airplane accidents receive coverage by news sources only when the news sources find it advantageous to do so.（B）

(E) Studies by government regulations show that the number of airplane flight miles remains relatively constant from month to month.

为什么是B？ 谢谢

不理解

同问！

是不是因为offcial的argument是not by an increase in the number of accidents,而B中直接给出 Airline accidents tend to occur far more often duringcertain peak travel months
即airlines accidents在某个时间有增加,直接否定了official的argument,所以weaken了argument......
这样想是不是太简单了?

没有nn来解答吗........

原文说，

因为，媒体对飞机事故的关注力增加

不是因为，飞机事故增加

所以，媒体讨论飞机事故的报道增加，

要削弱结论，就要削弱前提。所以B选项给出了一个原因，说是因为飞机事故频繁。
