Is A wrong because it says they "do not have significantly larger brains" which doesn't necessarily weaken the stimulus?

This question seems easier the second time around but I think I may have completely missed the word "significantly" which seems to be the main hint that A is incorrect.

Hi Teezo,

The "significantly" is one mark against answer choice (A). Another is that answer choice (A) treats the causal relationship as if it's proportional (ie more foraging is indicative of a bigger brain) whereas the causal relationship in the stimulus does not indicate it's proportional. The argument in the stimulus includes the possibility that foraging behavior causes a switch to flip in bees--it's not about the amount of foraging done but the very act of foraging in the first place.

Good work!
