Economist: One year ago, 64% of consumers said that their spending and saving habits had been “forever altered” by the recent recession. This year only 51% of consumers agreed with that same statement, so it is clear that a number of consumers have a poor understanding of the term “forever”.
Which of the following, if true, would NOT weaken the economist’s argument?
A. The consumers polled this year and last year do not represent identical segments of the population.
B. There were different recessions before last year’s poll and this year’s.
C. One may further alter one’s views without compromising an initial alteration.
D. Many of the consumers received a generous government stimulus this year.
E. Many of the consumers polled were pressured to answer no to this year’s poll by their employers.ulation.
VERITAS PREP OFFICIAL SOLUTION:
Solution: D
Questions in which only one of the five answer choices does NOT weaken an argument are difficult because students often assume that the correct answer must strengthen the conclusion. In general, however, on these sort of questions the best answer is just off-topic, out of scope, or otherwise irrelevant.
In this case, choice D is the irrelevant (and therefore correct) choice. For those surveyed to have so quickly changed their opinion of whether their habits had changed shows, consistent with the argument, that they did not mean (or understand) the absolute term "forever." One small change in their economic fortunes completely changed their absolute "forever" opinion.
For the other choices:
Choice A weakens the argument because it shows that the statistics provided do not connect. For the argument to hold, that 13% gap between the 64% who agreed with the statement last year and the only 51% who agreed this year needs to reflect at least some people who changed their minds.
Choice B weakens the argument because it changes which "recent" recession the respondents were referring to, again suggesting that there is no one in that 13% who simply changed their mind from "forever altered."
Choice C weakens the argument because it allows for people to change their minds without conflicting with their previous statement - those 13% for whom the opinion changed could have been fully understanding and fully truthful about "forever" and simply changed things later.
And choice E, like choices A and B, shows that the survey results themselves are invalid because the information wasn't properly collected.
