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: What will you do after graduation, Rose? ,F: I'd like to be a computer programmer. ,M: A computer programmer. Why? ,F: I want to make more money.

I want to be a computer programmer now because I want to get the first place in the competition and I just failed last week. (D) F: I guess so.

Input: Consider Input: F: Have you seen my coat? I am going to have to go down to the shop for more bread. ,M: Why? ,F: I'm not sure what happened. I made some sandwiches earlier and left them on the table when I went to answer the phone. But someone must have taken them, because they're gone. ,M: Oh, it must have been dad. I'm sure he was in the kitchen earlier. ,F: No, he went off to his tennis match before I finished making them, so he couldn't have done it. Anyway, he couldn't carry a plate of sandwiches as well as his tennis stuff, so I'm sure it wasn't him.
(A) M: Excuse me, can you serve me another plate of salad? (B) M: I’m sorry, I didn’t understand. Could you repeat a little louder, please? (C) M: Sorry, I haven't finished the homework you asked us to do. Can I hand it to you later? (D) M: I understand, my dear mom. But it wasn't me, neither.
