Input: Consider Input: M: I have read Mark Twain's book, The Adventures of Tom Sawyer. It's quite interesting and adventurous. ,F: But this book I'm reading is kind of boring. It only tells you some facts about Mark Twain. ,M: Oh, tell me something about Mark Twain, please. ,F: Well, when Mark Twain was 4, his family moved to Hannibal, a port town on the Mississippi River that gave him the idea for writing the book, The Adventures of Tom Sawyer. ,M: Oh, really? Anything else? ,F: In eighteen fourty-seven, when Twain was 11 years old, his father died. The next year, he began to learn printing. When he was 18, he worked as a printer in New York City. ,M: What happened next? ,F: Then on a voyage to New Orleans, the steamboat pilot, Horace, inspired Twain to become a pilot. And Mark Twain really received his steamboat pilot license in eighteen fifty-nine, after 2 years of hard work.
(A) M: So, on the voyage to New Orleans, Mark Twain wanted to be a pilot but Hannibal gave Mark Twain the idea to write a book? (B) M: So, New Orleans gave Mark Twain the idea to write a book but when he was 18, he still worked as a printer in London? (C) M: So, as Mark Twain never received his steamboat pilot license, he finally became a writer and Hannibal gave him the idea to write a book? (D) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that?

Output: A


Input: Consider Input: M: Hi Shirley, going to the football game today? ,F: No, I'm not. I'm planning to watch it on television. ,M: Why is that? Are you low on cash this month? ,F: Money is not the problem. I find it easier to follow football on television than in stadiums. When I see the game in person, I feel as if I'm too far away from the action and I always lose track of the ball. ,M: I know just what you mean. Besides on television, the new cameras they use give you super views of all the plays. But there's always so much excitement. People are cheering and shouting when I'm there in person and I end up cheering along with everyone else.
(A) F: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (B) F: Well, I think it's easier to follow the basketball on the television. (C) F: But I think it's easier to follow the game through television. (D) F: Actually, the only reason I watch the game on TV is that nobody will disturb me.

Output: C


Input: Consider Input: F: How was your trip, Dan? I'd love to go round the world. ,M: It was great. First we went to London but only for a few days as it rained all the time. Both of us got really wet. ,F: You went to Paris next, didn't you? ,M: Well, Paris wasn't at all, sunny, but it was better than London, a bit cloudy. ,F: Did you go up the Eiffel Tower? ,M: Yes. We both had a great time. ,F: Where did you go after Paris? ,M: To Sydney. We didn't get to the famous Bondi Beach as there were a lot of thunderstorms. We did some shopping there. ,F: I bet that was expensive. ,M: It wasn't as expensive as Tokyo. It was hot and sunny there, no rain at all for the whole 5 days we were there. ,F: And then you went to the USA, didn't you? ,M: Yes, to San Francisco, which is famous for its fog. It was so thick that we didn't go to see the Golden Gate Bridge. But it was warmer than some of the other places.
(A) F: Wow, cool. So you visited the Golden Gate Bridge. (B) F: Wow, cool. So you visited the Eiffel Tower and the Bondi Beach. (C) F: Wow, cool. So you visited the Bondi Beach. (D) F: I’m sorry, I don’t understand. Could you say it again?
