Is Answer Choice A incorrect because...

Hi @Andrew, Thanks for the question! So say that the honeybees aren’t of the same variety. Then just because the Africanized honeybees are superior producers doesn’t mean that they’re better than the native US honeybees. Because remember, we’re dealing with three regions here: Brazil, the US, and Africa. So if the honeybees of Brazil aren’t the same as the US ones, then we can’t say anything about the Africanized bees and the US local honeybees, because we don’t know anything comparing the two. The argument kind of assumes that the US local honeybees are the same as the native Brazil honeybees. So since this explicitly says that they’re not, it weakens the argument, and so is not the correct answer to this weaken EXCEPT question. Hope this helps! Feel free to ask any other questions that you might have.
