Input: Consider Input: M: Diana, can you give me a hand? I'm supposed to place all these new products in the display case, but they'll never fit. ,F: Yeah, I see what you mean. But did Miss Harper mean to put them all on display, or just one of each as a sample for the customers to see? ,M: Oh, I get it! So maybe I should just select a single example of each model instead of one of each color for each model. ,F: Check with Miss Harper first. But in my opinion, that's the only way you'll be able to do it.
(A) M: I manage to put them all in the case, but I can't find Ms.Harper to check. (B) M: It's all because of the limited space. Daisy, throw away these products. (C) M: Well, it's all because there isn't enough room for all the new products. (D) M: I'm sorry, I didn't catch that. Would you mind speaking more slowly?

The air will be so seriously polluted that nobody will be able to breathe normally. ,M: Exactly. People will have to rely on trains. ,F: Why do you say that? ,M: Well, we won't be able to use cars and the airports take too much space. That leaves trains. ,F: Huh, so do you think they'll be better trained systems between cities? ,M: Sure, they'll enable people to travel between cities in a matter of hours. There may even be trains going under the oceans to connect the main continents. ,F: Under the oceans? I get nervous enough flying on a plane.
(A) M: I feel as excited as you about train trip under the ocean. (B) M: I'm sorry, I didn't catch that. Would you mind speaking more slowly? (C) M: You don't have to be frightened.
