问题补充：

The policeman asked him to identify the thief.

A. name

B. distinguish

C. capture

D. separate

答案：

(答案→)A. name

B. distinguish

C. capture

D. separate

解析：句意：警察请他指认一下小偷。A. name指认，命名； B. distinguish区分，辨别； C. capture 俘获；D. separate分开。根据常识可知辨别是否是小偷不是普通老百姓应该做的；抓小偷当然不是普通老百姓应该做的；把小偷给分开，意思根本不同，根据句意故选A。
