Input: Consider Input: M: Hi Shirley, going to the football game today? ,F: No, I'm not. I'm planning to watch it on television. ,M: Why is that? Are you low on cash this month? ,F: Money is not the problem. I find it easier to follow football on television than in stadiums. When I see the game in person, I feel as if I'm too far away from the action and I always lose track of the ball. ,M: I know just what you mean. Besides on television, the new cameras they use give you super views of all the plays. But there's always so much excitement. People are cheering and shouting when I'm there in person and I end up cheering along with everyone else.
(A) F: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (B) F: Well, I think it's easier to follow the basketball on the television. (C) F: But I think it's easier to follow the game through television. (D) F: Actually, the only reason I watch the game on TV is that nobody will disturb me.

Input: Consider Input: M: Good morning, Madam. Are you being helped? ,F: No, I'm not. ,M: Where? I can certainly help you if you'd like some advice. This skirt and scarves over here are back in style. ,F: Oh, I'm here to look for a winter coat. ,M: How about this one? It's made of very high-quality wool. ,F: It's nice but actually I need something warmer. This would work if I were staying here in Los Angeles. But it's too light for Chicago winter.
(A) M: You are right. Here in Los Angeles, the winter is not very cold. (B) M: Excuse me, could you repeat the question? (C) M: Do not worry. The winter here in Chicago is hot, you should not wear winter coat. (D) M: You are right. Since you are in London now, you need buy some summer clothes.
