单选题
A
Researchers
have found subtle neurological B
differences between
the brains of men and women C
either
in physical structure and D
in the way
they function.
【正确答案】
C
【答案解析】解析：either一both。句意：研究人员发现了男人和女人大脑之间在生理结构和功能上细微的神经差异。句中“in physical structure”和“in the way they function”同作brains的后置定语，两者为并列关系，应该用“both…and…”结构。
