问题  
Theresa: Hi, Frank, your survey sounds very good. How many people filled it in?
Frank: I gave out 120 copies and I got 70 back.
Theresa: That’s a very high rate of return. Who did you give your questionnaires to?
Frank: I gave a copy to every student in my hall of residence and a few to friends from other colleges.
Theresa: Don’t you think that this will influence your results?
Frank: What do you mean, Theresa?
Theresa: The people in your hall of residence will all be about the same age. They are all students, most of them studying similar subjects and from similar backgrounds. Therefore it is likely that they will have similar opinions. Your results represent student opinion, not public opinion.
Frank: So how are you going to do your research?
Theresa: I’m going to interview my respondents in the shopping mall. I’ll ask them some multiple-choice questions and tick off their answers on my sheet. That way I can select people of all ages and attitudes, so my sample should be reasonably representative.
Frank: Isn’t it very difficult to ask meaningful questions using multiple choice?
Theresa: Yes, it is, but the secret to writing a successful survey is to write simple multiple-choice questions that target the information you are looking for. Therefore, it is better to write a lot of short specific questions than longer general ones.

Question 10
According to the woman, what is the secret to conducting a successful survey?

选项 A、Because he didn’t do it according to the requirements of his teacher.
B、Because the respondents he interviewed are all students who represent student opinion rather than public one.
C、Because his questionnaires are too simple.
D、Because he got a very low rate of return.

答案 B

解析 细节题。对话中,Frank说他把问卷发给同宿舍区的学生和其他一些大学的学生,而Theresa说他这样只能获得学生的观点而非大众的观点,故B为正确答案。A,C对话中未提及。D和对话内容相悖。
