Ex 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.
