Do you smoke? ,F: I don't smoke. ,M: That's good. Do you eat a lot of fruit and vegetables? ,F: Not really, especially no fruit. ,M: Well, since you don't eat fruit, I think you should drink more water because it helps fight colds. ,F: Really? Hmm...I don't like drinking water. But, well, uh, perhaps. ,M: There's no perhaps about it. And some exercise is needed to improve your health. ,F: Oh, I go swimming once a week. ,M: Well, you should go swimming 3 times a week, so that it really helps your health.
(A) F: You mean exercise is not needed, and it's enough to go swimming once a week. (B) F: I’m sorry, I don’t understand. Could you say it again? (C) F: Ok, I will go swimming twice a week. I hope it helps fight fever. (D) F: I think so. I hardly ever get sick because I go swimming 3 times a week.

(A) F: Well, we are living in the center of the city, so since today we are going to the countryside, I think it will take a long time to go there. (B) F: I’m sorry, I didn’t understand. Could you repeat a little louder, please? (C) F: That's awesome, but you know we are living out of the city, so perhaps I'll be late for a few minutes fot the aerobics class.

Example Output: D
