问题补充：

In societies where social roles are determined, boys usually copy the behavior of their fathers, and girls usually also copy of their mothers.

A. that

B. those

C. one

D. the ones

答案：

(答案→)A. that

B. those

C. one

D. the ones

解析：考查代词辨析。That知道可数名词单数或者不可数名词，表示特指，后面要有定语修饰。其复数形式是those，同样后面也要有定语修饰；one指代可数名词单数，表示泛指。The ones特指可数名词复数形式。本题的that指代不可数名词behavior后面有定语of their mothers修饰。故A正确。
