M: Do you think people's moods are affected by the climate they live in? ,F: Well, I think there's certainly something in it. Because when the weather is hot, I easily lose my temper, but when it's cooler I feel much calmer. And if it's raining, I always feel sad.
(A) M: Why do you feel angry when it's hot? (B) M: Excuse me, could you repeat the question? (C) M: Why do you feel sad when it's hot? (D) M: Why don't you feel angry but sad when it's hot?

A


Ex Input:
M: Why don't you have some of my cake, Sue? I made it just for this party. ,F: Sorry, Bill, I'm not in the cake at the moment. I thought you knew about my diet. ,M: On your birthday? Surely you can eat whatever you want on your birthday. You can start your diet tomorrow. And anyway, you look great. ,F: Well, thanks, Bill. I am not on a diet to lose weight, actually. My doctor told me to stop eating certain foods. I'm trying to avoid being allergic to something.
(A) M: Excuse me, could you repeat the question? (B) M: OK, I see. Your doctor didn't tell you to stop eating certain foods. You don't have the cake because you are trying to lose weight. (C) M: Really? You don't have the cake because you are trying to control a medical problem? (D) M: Yeah. You don't look great. I'm not surprised that you don't have the cake because you are trying to control a medical problem.
