(A) F: Oh. Hi. Could you please tell me your name? I have no idea that we are in the same class. (B) F: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that? (C) F: Oh. Hi, Bil. We are both teaching assistants now, although we teach different classes. (D) F: Oh. Hi, Bil. I'm so glad that we both work on the school magazine, although we are in different classes.
