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.
