This can be tricky. Answer choice (C) "neurological research" is not necessarily the same as brain size. Passage A talks about neurological research in terms of "brain imaging studies" about music (line 6), but Passage B does not present similar neurological research. Passage B mentions "face-to-face-mother-infant interactions" (line 42), but this is not a study with a direct neurological focus like brain imaging.
However, answer choice (B) "human emotion" is stated explicitly in each of the passages. This is seen in line 3 of Passage A and 35 and 57 of Passage B.

I don't understand how the observational data conducted from a behavioral analysis on mothers and baby's does not constitute neurological research? Human emotion itself and the expression of such feelings during "face-to-face-mother-infant interactions" would be an example of data collected from studies on how the nervous system functions during adolescent years of brain development. I would believe this to be neurological research why is it not considered as such?

Hi, neurological research is that that focuses on the brain itself, research in how mothers and children interact is likely psychology or development
