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.
This supports fact 1. It doesn't do anything for fact 2.
(B) The total time allotted to the average cluster of consecutive television commercials is decreasing.
If the total time is decreasing, then the chances of brand name commercials being in the middle is less. Does not support.
(C) The average number of hours per day that people spend watching television is decreasing.
Out of scope. Doesn't explain/support how brand names are not being recalled with their position in the cluster.
(D) The average number of clusters of consecutive commercials per hour of television is increasing.
if there are more clusters, then theres more chances for viewers to catch the first or last commercial in the cluster which could be brand names. Does not support
(E) The average number of television commercials in a cluster of consecutive commercials is increasing.
if the number of commercials in a cluster is increasing, then the chances for brand names to be in the middle is greater. This supports fact 2. Pick E
