A、The man. B、The woman. C、The clerk. D、The director. C推理判断题。本题问的是谁应该为男士的问题负责。对话中女士提到注册数学课程并不需要出生证明，三个星期前在此工作的职员一定弄错了。由此可见，此职员应该为

M: Excuse me, I want to register for this mathematics course.
W:(12)I’m sorry registration has been closed.
M: Closed? The clerk told me I could come back and register at any time during the first week of classes.
W: Well, that’s not possible. The computer’s official student account has already been sent to the state at the beginning of this semester. And that’s what our budget is based on. Where did you get that information anyway?
M: A woman here when I tried to register three weeks ago. She said I just had to pay a late fee.
W: She must have been a temporary worker. Why didn’t you register then?
M:(13)She said I couldn’t until I had my birth certificate.
W: Your birth certificate?
M: Well, I’m a new part-time student. So she asked for identification.(13)I left my certificate at home. It’s rather far from here.
W: Huh. That’s no reason to demand a birth certificate. We only need to establish residency: a phone bill with your name and address on it would’ve been fine.
M: Really? Only proof of my address?
W: Yes.(14)I’m afraid she gave you the wrong information. Still you’ll have to wait and take your math class next semester.
M: But that’s unfair. That’s not my fault.
W: Well, I sympathize with your problem, but frankly, I don’t think there is anything anyone can do for you. You were trapped in the system.(15)If you want to, you can talk to the director. She will help you if she can.
M: Great.
W:(15)Don’t get your hopes up.
12. Why can’t the man register for the math course?
