[Q]: M: Welcome back to your student union radio station. I'm with Catherine, who just successfully climbed the Great Mountain, Mont Blanc. Actually, she once did. The same climb in 2007. Catherine, was it easier the second time around? ,F: In many ways. They were totally different experiences. The first time I went as part of an organized group. We took 4 days to reach the top. This year, I decided to go alone with just one overnight stop, actually you're never really alone. It's all been crowded up there. The first climb, was quite difficult is the weather was very changeable, and we found ourselves climbing in very cold windy conditions. The weather this time was wonderful. Plus. I spent a few days before in chamonix and got myself more used to the height. If it's certainly made it easier, you can also achieve the same thing by climbing some of the smaller mountains first.
(A) M: It's a good idea to spend a few days in Chamonix, which makes climbing easier. (B) M: You are so great! Betty, I should learn to you and make a detailed plan. (C) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that? (D) M: You climb smaller mountains for training before your third time to climb Everest.

[Q]: 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?
[A]: A
