Input: F: Ted, it's really you. I just can not believe it. You've really put on some weight. ,M: Yeah, that's true. Actually I'm losing weight now. Now I go to the gym at least 3 times a week. So how have you been? ,F: Not bad. I've changed my job, you know. Now I'm not as busy as before, and I spend more time hanging out with friends and sleeping. ,M: Do you also exercise? ,F: Not really. But I'm on a diet. I don't want to put on any weight.
(A) M: Cool. I never go to gym, yet I lost so much weight that you couldn't figure out who I am. (B) M: I'll join your exercise to put on weight. I've partly succeeded that you didn't recognize me. (C) M: Keep on. Look, I'm not as thin as before and you failed to find out who I was at first glance. (D) M: I’m sorry, I didn’t catch that. Would you mind speaking more slowly?
