Input: M: Barbara, could you cover for me for a few hours? ,F: I guess so, Sam. I could tell the boss you've gone to buy some office supplies if she asks. ,M: Thanks, I owe you one. ,F: Hey, not so fast, Mister. I need to know where you're going. Why do you need to be gone for that long? ,M: I forgot to get my dad something for Father's Day. ,F: Oh, man! You forgot your own dad's birthday? ,M: No, it's not his birthday. It's Father's Day! ,F: Since you're going, would you mind picking up something for my dad too? ,M: Oh, well, I guess I don't really know your dad though. Do I? ,F: Couldn't you just buy a couple of ties in the shop downstairs? That would be easy enough, and that way you could come back before Mrs Greenway checks on us.
(A) M: I don't think so. I should go to the office supplies store now. (B) M: I didn’t hear you. Please could you tell me again? (C) M: Ties from the shop downstairs? That sounds wonderful! My dad will love that! (D) M: I don't know. Maybe my father and I should go shopping trips together for a couple of times to see what he likes.
