Input: Consider Input: F: What do you plan to do tomorrow? ,M: I have no plan. Maybe just stay at home and read a book. ,F: The weather report said it would be fine tomorrow. What about going on a picnic? ,M: Just you and me? ,F: No, I have invited my friend Sarah and her boyfriend. ,M: Why not? I love going on picnics. ,F: Great. What about picking you up at 10 o'clock tomorrow morning? ,M: OK.
(A) F: Since you'll take the bus, let's meet at the station. (B) F: So you and your girlfriend Sarah will walk there? Fine. (C) F: I will arrive to your home at 11:00 and drive you there. (D) F: I am afraid I did not quite catch what you were saying. Please repeat it.

Input: Consider Input: M: Would you consider buying a self-driving car? ,F: I don't know. I guess I'd have to research a bit more about them before making that decision. ,M: It will probably be a while before we are able to buy them anyway. We might be seeing self-driving trucks on the road pretty soon, though. Google wants to change the commercial trucking industry. Right now, there are over 3 million truck drivers in the US, so adding self-driving trucks would likely take away a lot of jobs. But many drivers might still be able to accompany their trucks and get a full night's sleep in the process. ,F: Truck drivers cause a lot of accidents on the freeway, so I think I'd like to see self-driving trucks. It would make me feel safer on the road. ,M: Really? I think it might make me feel less safe. A human driver is much more likely to react quickly to something unexpected.
(A) F: I am not agree with you, I don't think they are safer. (B) F: I am really sorry, I did not catch that. Would you slow down, please? (C) F: I am not excited by their speed because I think they are not safe at all. (D) F: Are you serious? I don't understand why you feel scared by them.

Output: D


Input: Consider Input: M: I saw your advertisement about the X20 model in the morning paper. The monitor seems to be excellent. And the keyboard is not bad. But do you think the price is a bit too high? ,F: I think it's a good buy. The price includes the mouse, you know.
(A) M: The price is definitely too high. Besides, the price doesn't include the mouse. (B) M: Still, it's too expensive for me. (C) M: Everything is fine, except the monitor. (D) M: I didn’t hear you. Please could you tell me again?


Output: B
