12.  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.

请问大家这道题，D为什么不对呢？虽然我也最后觉得答案E是合理的。但是总觉得D有点想不通为什么不对，请指教。

谢谢！如果每个小时之内的广告数量增加的话不是也可以作为解释吗？

我觉得D说的是The average number of clusters of consecutive commercials  只是说广告组增加了但并没有强调fist,和last之间middle广告数量的增多 所以不能引起FACT1说的现象 E却说 a cluster of consecutive commercials is increasing.明显弥补了这个gap 因为middle广告太多了 根本记不住
