13. (D)
Question type: Explain a result
Since people between the ages of 46 and 55 spend the most money per capita, we would expect advertisers to focus on them. Instead, the advertisers focus on a much younger group of consumers. Is there a reason that the economic potential of the middle-aged viewers is ignored? Yes, if advertisers think that advertising would not be an effective way of altering these consumers’ spending habits, as choice (D) suggests.
(A) doesn’t explain why the advertisers don’t target people between 46 and 55.
(B) really makes the advertisers’ behavior mysterious, since the slots that would reach the people who spend the most are cheaper.
(C) is irrelevant; we don’t care about explaining the TV executives’ decisions, we want to explain the advertisers’ decisions.
(E) brings up the irrelevant issue of print advertising.
