单选题 Man: We've got three women researchers in our group: Mary, Betty and Helen. Do you know them?
Woman: Sure. Mary is active and sociable. Betty is the most talkative woman I've ever met. But guess what? Helen's just the opposite.
Question: What do we learn from the woman's remark about Helen?

A、 Helen is talkative.
B、 Helen is active.
C、 Helen is sociable.
D、 Helen is quiet.

【正确答案】 D

【答案解析】男士：“我们有三个女研究员，玛丽、贝蒂和海伦，你知道她们吗?”女士：“当然，玛丽为人很积极，具有亲和力。贝蒂是我见过的最能说的人。但是知道吗?海伦却正好相反。”从女士的话中可知，海伦是与贝蒂性格相反的人，说明海伦很安静，D项答案符合题意。
