Question RC

@maonuo, Passage A suggests that music has little evolutionary advantage given that both music and language are part of the same neurological system but most people are not as skilled at music as at language. Passage B cites alternative evidence to draw a different conclusion, suggesting that music has an important evolutionary purpose because it promotes the bond between the mother and the child. Hence, (A) is an accurate description of the relationship between the two passages.

Thanks again Irina!
