Fact 1: Television advertising is becoming less effective: the proportion of brand names promoted on television that viewers of the advertising can recall is slowly decreasing.

Fact 2: Television viewers recall commercials aired first or last in a cluster of consecutive
                
commercials far better than they recall commercials aired somewhere in the middle.

 

Fact 2 would be most likely to contribute to an explanation of fact 1 if which of the following were also true?

A. The average television viewer currently recalls fewer than half the brand names promoted in commercials he or she saw.

B. The total time allotted to the average cluster of consecutive television commercials is decreasing.

C. The average number of hours per day that people spend watching television is decreasing.

D. The average number of clusters of consecutive commercials per hour of television is increasing.

E. The average number of television commercials in a cluster of consecutive commercials is increasing.

答案是E,

不明白为什么D不对, 我觉得D和E表达的意思都一样啊

请指教! 谢谢

不一样。D是说每小时里广告群的数目多了,而E说每次广告群的长度越来越长。
因为fact 2说人们更容易记住首尾的广告,所以每小时里广告群越多(imply 每个广告群时间短了)人们记住的广告就可能越多。
