Question RC

@maonuo Happy to help! The correct answer is (C) "Is it at least partly a result of evolutionary increases in brain size?" Both authors are likely to agree that the answer to this question is yes. This is discussed in lines 19-21 of Passage A and lines 50-62 of Passage B. There, each passage makes an association between an evolutionary increase in brain size and human musical capacity. Does this help? Let us know if you have additional questions!
