Last week only two people came to look at the house wanted to buy it. A. none of them

问题补充：

Last week, only two people came to look at the house, wanted to buy it.

A. none of them

B. both of them

C. none of whom

D. neither of whom

答案：

A. none of them

B. both of them

C. none of whom

(答案→)D. neither of whom

解析：由于前面提到的是两个人，故后面只能用表两者的both或neither，据此可排除A和C。由于空格前用的是逗号，且没有连词，故只不能选B，而要选D，因为neither of whom为非限制性定语从句，用以修饰two people。
