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?

Example Input: F: Hi, Rob. Do you mind if I eat lunch with you? ,M: No, Mrs. Evans, not at all. ,F: Thanks. I've just heard you study nutrition and you've got quite a lot of experience working in the cafeteria, so I wonder if you are interested in a small project we're doing this term. ,M: What is the project about? ,F: More and more students prefer not to buy meals here and we want to attract them back. I want to know what the students would like to eat. Your job will be finding this out. Of course, I also like to hear any of your ideas. ,M: Well, if the menus were changed, maybe I wouldn't have to listen to so much criticism this term. You know, everyone in the nutrition class sees me when I serve food here, so they always complain to me about the food here.
(A) F: Excuse me, could you repeat the question? (B) F: Now that your job is cooking food for the students, you can ask them what they like to eat.
