Ex Input:
M: Sometimes I wish I could live on a deserted island. ,F: Why do you feel that way? I don't think I could stand being away from people for so long. ,M: Who said it had to be long? I'd like to live there for just half a year or so. It'll be fun to try it out. I read about a young guy who ran his own Internet business. He could do all his work online. So it didn't really matter where he lived. One day, he decided that he was sick of being around people and doing all the regular things that he did. He wanted a break, but not just a little vacation. So he found a beautiful small island, where he could live quietly without anyone around him. He caught his own fish, filled containers with rainwater and connected to the Internet through satellite. He did this for 6 months and then came back into society. ,F: It must have been a wild experience. I'm impressed.
(A) M: I am really sorry, I did not catch that. Would you slow down, please? (B) M: Although you are impressed by his story, the ending of the story is that he never returned to the society. (C) M: How could you not be interested in this story? He's a fisherman! (D) M: Are you going to do the same thing as him? He never returned to society.
