F: Have you seen my coat? I am going to have to go down to the shop for more bread. ,M: Why? ,F: I'm not sure what happened. I made some sandwiches earlier and left them on the table when I went to answer the phone. But someone must have taken them, because they're gone. ,M: Oh, it must have been dad. I'm sure he was in the kitchen earlier. ,F: No, he went off to his tennis match before I finished making them, so he couldn't have done it. Anyway, he couldn't carry a plate of sandwiches as well as his tennis stuff, so I'm sure it wasn't him. ,M: Well, it wasn't me. But look, are these your sandwiches here, on the bottom shelf of the fridge? ,F: Are they there? Oh, my goodness, I must have put them there when the phone rang. Oh dear, I really must be losing my mind. ,M: Well, you needn't go to the shop now. Let's have lunch.
(A) F: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that? (B) F: Come on, let's have lunch now. (C) F: No, I'll go shopping first.
