This is a weakening question, as the question stem asks: Which one of the following, if true, casts the most doubt on the author’s hypothesis?

This is a fairly straight forward correlation-causation argument. A study finds that smokers are more likely to snore, and concludes that smoking can cause snoring. Our job is to weaken this argument. Let’s see what we get:

Correct Answer Choice (A) This provides an explanation for why snoring and smoking would correlate, even when smoking might have no influence on snoring, namely that the two share a third cause, stress.

Answer Choice (B) Ok, but unless we know obesity leads to snoring this does nothing for us.

Answer Choice (C) This is completely compatible with the argument.

Answer Choice (D) Same as C.

Answer Choice (E) Interesting! But this could be true while smoking caused snoring, and does nothing to suggest it doesn’t.
