GMAT Critical Reasoning (CR) | Re: Studies show that children who listen too much classic music

Here is a way I derived the answer A (after wrongly chose B) - I think it's just for my understanding, not sure if with this approach I will consume much more time or not during the real exam.

(The bracket indicate negate. e.g X, (X) = not X)



Please discuss more.

Thanks,
HL
