Question Type:
Explain a Result
Stimulus Breakdown:
Expected: Businesses that use a customer survey should do well.
Unexpected: Businesses that use customer surveys did worse than other businesses that didn't.
Answer Anticipation:
We need to explain why the survey group has declining profits, while the non-survey group doesn't. Keep focused on the difference between the two groups.
We don't have much other information to go on! We know that businesses use survey in an attempt to improve sales/increase profits, but we don't know if they actually work. First thought here might be that the surveys are somehow hurting these businesses, despite their best intentions.
Correct answer:
(C)
Answer choice analysis:
(A) We don't know that any business increased their profits - the non-survey group just didn't have declines. But even if they had, this wouldn't help explain *why* they did.
(B) The fact that surveys are routine doesn't explain anything about profits declining.
(C) This answer gives us a completely different explanation though. The surveys themselves aren't hurting the businesses. But they are correlated with complaints! The complaints trigger the surveys, but they probably also trigger declines in profits!
(D) First, this only tells me that sometimes the customers respond inaccurately. But more importantly, I have no idea how that inaccuracy relates to profits! The inaccuracy probably makes the survey less effective, so many it might explain why profits don't increase, but not why they decline.
(E) Like (D), this suggests the surveys don't end up being very effective, but not why profits actually declined. Additionally, this is only about some of the businesses in the survey-group!
Takeaway/Pattern:
Be sure to read through a question stem that's giving you more information than usual! This stem pretty much spoils the entire question for you.
