You will be given a definition of a task first, then some input of the task.
In this task, you will be shown a conversation. You need to write a question with three choices for the conversation. Your question should be answerable based on the conversation and only have one correct answer. Note that you don't need to answer your question. "W" and "M" in the conversations stand for "woman" and "man".

M: Maths department, Doctor Webster speaking. W: Hello, Professor Webster, this is Janet Wang calling. I'm living two doors down from your teaching assistant, Ken Williams. Ken asked me to call you because he has lost his voice and can't talk to you himself. M: Lost his voice? Oh, what a shame! Is there anything I can do for you? W: Well, Ken has a class this afternoon from two-thirty to four and he won't be able to teach it, but he doesn't want to cancel it either. M: Want me to try to find somebody else to teach the class? W: No, not exactly. What he wants to do is to get someone to go in for him, just to pass back the midterm exams. He's already marked them and they are on the desk in his office. The whole thing wouldn't take more than ten minutes. M: His classes are two-thirty, eh? Well, I'm afraid at that time I'll be on campus anyway; so I can do it for him. W: Thank you very much, Professor Webster.
Output:
