Question

【题目】—How did you keep in touch with the agent, Mary?

— I surfed the Internet and called ______ whose telephone number is provided.

A. one B. those

C. the one D. that

Answer 1

【答案】A

【解析】

考查代词。句意：你是如何和你的代理商取得联系的？—我上网然后打电话给一个提供电话号码的代理商。本句中使用one指代可数名词单数agent，相当于an agent。CD项表示特指，those是复数形式，与句子的is矛盾。故A项正确。
