求教
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 the 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 accidents, 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 srurounding airline accidents is largely limited to the coutnry in which the crach 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 new sources find it advantageous to do so. e: studies by government regulators show that the number o fairplane flight miles remains relatively constant from month to month.
