Example Input: M: What's wrong with you, Lucy? ,F: Our dog Rusty is lost. Someone left the backyard gate open and he got out. My daughter is so upset right now. ,M: Have you called the local dog shelters? ,F: Well, they haven't seen him. They said they would call me if they find our dog, but I don't expect miracles. It's 2 days and... ,M: We can always look for miracles. Does he have any identification on him? ,F: He's wearing his sweater. He's brown with white spots and... Sorry, 'm not thinking straight. You know, he's a big part of our family. We got him when he was a little puppy. I'm just worried he was stolen or is injured somewhere. ,M: I understand. I used to pet dogs, too. Let's walk around the neighborhood. Hey, look! There he is. ,F: Rusty! Come here boy! Oh, Glenn, I can't thank you enough. I owe you a big favor.
(A) M: I didn’t hear you. Please could you tell me again? (B) M: You are welcome. I am so glad that we found Rusty. (C) M: Honey, don't be too worry, the local cat shelter called me ten minute ago.

Example Input: F: What do you think about this idea? Going for a picnic. ,M: Well, I'm not sure, I think it's a bit boring. I think barbecue on the beach would be more fun. ,F: Yes, I agree, but it's quite a lot of work. Someone has to stand here and cook all night. I think we should go to a restaurant instead. ,M: That's true, but it's quite expensive to go to a restaurant. ,F: Well, what about having a party at someone's house? We could order a pizza or just some hamburgers. ,M: I suppose so, I think a fancy dress party is a good idea. We could have a competition and decide who is wearing the best clothes.
(A) F: I agree with you. Having a picnic is the best idea. (B) F: Yeah. We should have a barbecue on the beach. (C) F: I am afraid I did not quite catch what you were saying. Please repeat it. (D) F: Yeah. We will have a fancy dress party and a barbecue.
