Studies show that impoverished families give away a larger percentage of their income in charitable donations than do wealthy families. As a result, fundraising consultants recommend that charities direct their marketing efforts toward individuals and families from lower socioeconomic classes in order to maximize the dollar value of incoming donations.
Which of the following best explains why the consultants' reasoning is flawed?
(A) Marketing efforts are only one way to solicit charitable donations.
(B) Not all impoverished families donate to charity.
(C) Some charitable marketing efforts are so expensive that the resulting donations fail to cover the costs of the marketing campaign.
(D) Percentage of income is not necessarily indicative of absolute dollar value.
(E) People are more likely to donate to the same causes to which their friends donate.
OFFICIAL EXPLANATION
(A) Marketing efforts are only one way to solicit charitable donations.
This Out Of Scope answer discusses an Irrelevant Distinction. It may be true that there are other ways to solicit donations besides marketing efforts, but the argument itself is about marketing efforts.
(B) Not all impoverished families donate to charity.
This answer is One Word Off It makes a statement about “all” impoverished families, but the argument never says that all o f these families act in the same way. (Note: many people will eliminate this answer because the word “all” is extreme. It's true that this argument does not provide support for the extreme word “all,” but extreme words can appear in correct CR answers— if the argument provides support for the extreme word.)
(C) Some charitable marketing efforts are so expensive that the resulting donations fail to cover the costs of the marketing campaign.
This is an especially tricky Wrong Detail answer. The argument never talks about whether the marketing campaign will be “profitable” (that is, make more money than was spent on the marketing campaign). It might seem like this should be the goal o f any charitable marketing campaign... but the argument doesn't address this.
(D) Percentage of income is not necessarily indicative of absolute dollar value.
This is the correct answer.
(E) People are more likely to donate to the same causes to which their friends donate.
This sounds plausible in the Real World, but it's just a distraction here— the argument doesn't address this issue.
