Complete Question Explanation
Weaken-CE. The correct answer choice is (A)
This passage cites a study which shows that snoring is more common among smokers, so the referenced author concluded that smoking might cause snoring. Since we are asked to weaken this causal argument, and we know that the effect under discussion is snoring, we are probably looking for an answer choice which provides an alternative cause, or leads us to question whether smoking could be the cause.
Answer choice (A): This is the correct answer choice, which provides, as predicted, an alternative cause for snoring—stress.
Answer choice (B): The cause of smoking is not at issue here—the question is whether smoking causes snoring.
Answer choice (C): This tells us nothing about whether or not smoking might cause snoring.
Answer choice (D): Like answer choice (C) above, this proportion provides no insight into the question of whether there is a causal link between smoking and snoring.
Answer choice (E): Similar to incorrect answer choice (B) above, this is irrelevant. Effects of smoking or snoring have nothing to do with whether smoking might cause snoring.
