Example Input: M: So, Gilda. I'm sure we both have to deal with homesickness, because we're so far away from our own country. ,F: Yes, it's very difficult. In special seasons like Christmas or during the Holy Week, it is something that we celebrate a lot and I really feel homesick. ,M: How do you deal with homesickness? ,F: When I feel homesick, I never stay at home alone. One thing I do is that I always try to go for things in the neighborhood. So what do the locals do? Is there anything interesting? And it's a sort of adventure because you're doing something new, so you're kind of replacing something that you used to do by something new. So, in a way, it's nice dealing with homesickness. ,M: Yeah. ,F: What about you? ,M: Well, that's what I was going to say. You said replacing and I also focus myself on other activities, such as playing golf, swimming and watching TV. But what I like best is to go hiking with the friends I've made and we talk a lot. ,F: You are really outgoing. There're a lot of delicious foods to enjoy. Delicious foods can make you forget unhappy things. ,M: Yeah, I couldn't agree more. I also do that when I'm feeling homesick. Maybe next time we can go out and enjoy some foods together.
(A) F: Good idea. We can chat with each other when we feel homesick. (B) F: Good idea. We can have meals together with family members when we feel homesick. (C) F: Good idea. We can have meals together when we feel homesick. (D) F: I’m sorry, I don’t understand. Could you say it again?

Example Input: M: Miss Robertson, for the past 3 weeks, I've been getting complaints about your work. ,F: Uh...What do you mean?

You're often absent from staff meetings and you haven't been getting along with your colleagues. ,F: Look, Mr. Travers, I can explain.
