Example Input: M: Hey, Jenny, what's the matter? ,F: I was just online in a chat room with three Germans. They used a lot of idioms on purpose and I didn't understand, so I asked them what they meant. Then they started to ignore me and after a while I started to feel stupid. ,M: Oh, you shouldn't. Your German is really good. ,F: But it seems they were using their German ability to have fun with each other. They didn't really want to include me. ,M: Well, some people are like that. That's all. You can't let them bother you. One nice thing about chat room is that you can leave and go to another one.
(A) F: I agree with you. The advantage of the chat room is that you can make more friends. But you can't enter or leave freely. (B) F: I agree with you. The advantage of the chat room is that you can express yourself freely. But you can't enter or leave freely. (C) F: I agree with you.
