This is a weakening question, as our stem asks: Which one of the following, if true, would most weaken the argument?

Our stimulus begins the claim that learning how to build a nest is important for the breeding success for birds. As an example of this claim’s truth, we’re told about a study where blackbirds were less successful breeding while nesting than older birds or even themselves are a year later. So there is a correlation between nest building and high breeding success, got it. To further strengthen the conclusion, the argument eliminates the alternate explanation that it is just about how large and strong the birds are, because they are fully grown once they leave their parents nest. The stimulus ends by reaffirming its conclusion that nesting benefits breeding success. Since this is a weakening question, we want to find an answer that undermines this hypothesis that the higher breeding rates are because of the nesting. Let’s see our options:

Answer Choice (A) Who cares? They could build really nice nests and it still be true that nesting experience benefits breeding success.

Correct Answer Choice (B) This gives an alternate explanation for the increase in breeding success; it’s not their nesting experience, but their experience of attempting to breed, which leads to an increased success rate over successive years.

Answer Choice (C) This would support the conclusion that nesting experience contributes to breeding success.

Answer Choice (D) So just as the argument stated, it’s not because of size and strength; this does not weaken the argument at all.

Answer Choice (E) Ok but we are interested in the increase after they started to nest; who cares about the birds that didn’t make it (no offense to any avian 7Sagers)?
