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.
(E) Studies by government regulations show that the number of airplane flight miles remains relatively constant from month to month.
Answer is B, while I choose C.
What's the problem with C? Isn't it suggest that News Organization is not biased when selecting the coverage of an accident? Thus it can further weaken the officials' assertions of the increase in the number of news sources covering the accident, can't it?
题目的结论：publicity is caused by an increase in the number of news sources covering airline accident, not by an increase in the number of accidents.
要反对，只要说：就是by an increase in the number of accidents即可。
所以B正确。C中的 how severe 是无关词，题中根本没说，排除。
