Example Input: M: Researchers in America did some experiments to try to figure out why some people gain weight more than others do. ,F: Yeah, some people can eat whatever they want and they never seem to gain a pound. ,M: In this study, volunteers were given 1000 extra calories a day. About 2 pieces of cheese's worth of extra intake. ,F: This kind of study I'd like to be in.
(A) M: You prefer excise and you don't want to take 1200 extra calories so you don't like this experiment. (B) M: Just a minute!

Example Input: F: Hey, Robbie. You're completely wet and covered with powder. So many colors! I mean, you look like a rainbow. What happened? ,M: I've just come back from visiting my family. You know, we're from India and today is our Spring Festival Day. We call it Holly. ,F: That's all very interesting. But I still don't understand why you look like that? ,M: Well, we celebrate Holly by throwing colored powder and colored water at each other. And we light big fires, too, to show thanks to the gods. ,F: Interesting. But aren't you afraid that you'll catch a cold and get ill? I mean, you're completely wet. ,M: Actually, the things we throw at each other helped to keep us healthy. ,F: What do you mean? ,M: Well, the colored powders we throw are made from traditional Indian medicines. ,F: And the coloured water, too? ,M: The coloured water comes from the yellow flowers called Palash, and they're good for you, too. ,F: Amazing. It sounds like a lot of fun. ,M: It really is. Next year, if you're interested, I'll bring you along. ,F: That would be great. I'll make sure I keep February second free. ,M: Actually, Holly isn't like Christmas. The date changes from year to year.

(A) F: I'm sorry, I didn't catch that. Would you mind speaking more slowly? (B) F: At the end of winter? Are you kidding me? That must be very cold to be wet with water!
