Example Input: M: Hello, my name is Peter Jones. I'm your new neighbor. I just moved in next door. ,F: Oh, nice to meet you. My name is Miss James. I hope you enjoy living here. ,M: I hope so, too. You know when we were considering whether to buy the house, Mr. Johnson, the housing agent told us that jogging was very popular here. I am a big fan of jogging. I used to go jogging every day in my old neighborhood. ,F: Aah, yes. Many people here love to jog. I go jogging twice a week. ,M: Can you tell me a good place to go jogging near here? ,F: Sure, the long coast path along the beach is a perfect place for jogging. ,M: Coast path. Sounds nice. Is it far from here? Can I walk there? ,F: Yes, it's only a 5 minute ride from here. ,M: Oh, I see. Anything in particular I should know about jogging there? ,F: Emm, yeah, just be sure to wear sunglasses there. The sunlight there is very bright and it can be hurt on your eyes. ,M: Thanks for the advice. So are there any other activities to do there on the beach? ,F: Oh, yes, beach volleyball is also very popular. A lot of people play there on the beach.
(A) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (B) M: Haha, since you have lots of sunglasses and go jogging every day, we can go to the beach together. (C) M: Yeah, my new neighbor Mr. Johnson likes jogging very much. (D) M: Although beach volleyball is another popular activity there, but it's a 25 minute ride from here.
Example Output: A

Example Input: F: Why did you decide to publicize climate change in this way? ,M: Well, I was really upset about some countries failure to sign up pollution control agreements. It felt like the science wasn't getting understood by the politicians, so I decided to look into what I personally could do, that led me to dream up a cartoon character called Mr Carbon. We all know somebody like him, he's climate ignorant and makes no effort to save energy. Of course, factories are the obvious bad character in the real world, but I couldn't do much about them. ,F: So, are we going to see him in scenes like we get in disaster movies? ,M: That's pretty unlikely, it's hard to make a box office success. But he certainly gives cause for concern. People are becoming more aware of the climate change.
(A) F: OK. You believe Mr. Carbon has made a box office success and people are becoming less aware of the climate change. (B) F: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (C) F: Okay, I see. You said Mr. Carbon has played a role in a disaster movie but gives no cause for concern. (D) F: Well, in your opinion, Mr. Carbon has aroused people's concern about climate change.
