OE for reference:
Overview:The argument states that advertisers target young adults in an attempt to create brand loyalties and that they choose young adults because they have higher discretionary income. The passage also says that people over age 65 will soon have higher discretionary income than young adults. The argument concludes that in the future, advertisers would do better to target adults over 65. You are asked to identify a statement that weakens the argument.
The Correct Answer:B We are told that advertisers currently target young adults in order to create brand loyalties. Given that this is the purpose for targeting a particular age group, an important factor in choosing which group to target is whether they already have established brand loyalties. If, as (B) says, older consumers are more likely to already have established brand loyalties, this makes them a less promising target for television advertising. This tends to offset the fact that they will have higher discretionary income than young adults in the future. Thus, if (B) is true, it weakens the argument that advertisers would do better to target those over age 65.
The Incorrect Answer Choices:A (A) implies that advertisers should place advertisements on a particular set of shows if they want their advertisements to reach people over age 65. But that doesn't imply anything about whether targeting people over 65 is a better advertising strategy than targeting young adults.
C The argument states that those over 65 will soon have more discretionary income than young adults. (C) doesn't change that. If the discretionary income of young adults is projected to rise, then—assuming the argument's premise is true—the discretionary income of those over 65 will rise even more. So whatever support the premise provides for the conclusion will still be there. Thus, (C) does not weaken the argument.
D The argument concludes that advertisers would do better in the future to target those over 65, based on the premise that they will have higher discretionary income than younger adults. (D) provides additional reason to think that advertisers should target consumers based on discretionary income and therefore, if anything, (D) strengthens this argument.
E If we add (E)'s statement about an increase in the number of consumers over 65 to the premise that these consumers will soon have higher average discretionary income than young adults, this gives advertisers even more reason to target people over 65. So, if anything, (E) would strengthen the argument.
