Fact 1 & 2

by BTGmoderatorDC » Wed Sep 13, 2017 3:50 am
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.

I'm quite confused on this, What's the best approach to determine the answer? Please help me with this experts

We're trying to reconcile two facts: 1) people remember fewer brand names from commercials; 2) people are more likely to remember the brand name from the first and last commercial than they are for one somewhere in the middle of a string.

So imagine a simple scenario. Say you had three commercials: A, B, and C. If you're likely to remember the first and last from the string, you'd recall A and C, and thus recall 2/3 of the brand names you saw.

Say you had four commercials: A, B, C, and D. Again, you'll likely recall the first and the last, this time A and D, and thus recall 2/4 of the brand names.

Notice that as we add more commercials to the string, the number of brand names a viewer is likely to recall goes down. This is what E conveys.
