M: Hi, Mary. ,F: Oh, hi. Sorry, but you are? ,M: Peter, Peter Parker from your math class. ,F: Oh, Peter, how are you? ,M: Fine, thanks. Actually I'm working on our assignment and I can't seem to figure out the last problem. And the teaching assistant is out of town. So I was wondering if you could help me. ,F: You mean like now? I have swimming practice in a few minutes. And then I have to study for a biology exam. I could meet you right after dinner.
(A) M: I know our assistant is in her office but I don't like her. (B) M: You are so busy! I am working on the exam and I have a few questions, but our assistant is not present right now. (C) M: You are so busy! It's too bad that our assistant is not present right now. (D) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that?
