Example Input: 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.
