F: What are you guys doing? ,M: Can't you see? We're making paper airplanes. ,F: Yeah, I see that, but what are you doing with them? ,M: We're flying them, of course. ,F: Out of the window? ,M: Yeah. ,F: That isn't right. You shouldn't throw paper out of the window near the land on the street and someone will have to pick it up. You're just making the street dirtier than it already is. ,M: No, we aren't. First of all, we're not throwing the airplanes out. We're making them fly. And second, most of our planes aren't going on the street. ,F: Where are they going? ,M: See that building across the street from us? We are sending them on to the roof of that building. We've already gotten more than 50 on there.
(A) F: I just see a crowd of people. You are making the street cleaner than it is. (B) F: I saw a big airplane just now. Most of your planes are going on the street. (C) F: I never see the building. You've already gotten more than 100 on the roof. (D) F: Just a minute! I do not quite follow what you are saying, would you mind repeating that?
