Ex 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.
