M: Hi, this is the Friends of the Environment office, isn't it? ,F: Yes, it is. ,M: Oh, good. My name is Ben. I'm doing a project at school about the environment. And my teacher said, this would be a good place to get some information. ,F: Well, I'd be glad to help however I can. What's your project about, exactly? ,M: Well, I haven't quite figured that out, yet. That's kind of why I'm here, actually. ,F: I see, um, do you know much about the greenhouse effect? ,M: Yeah, but I think a lot of people are already doing that topic.
(A) F: I agree with you. That topic isn't a serious problem, although few people are doing that topic. (B) F: You're right. There is little information on that topic and few people are doing that topic. (C) F: Excuse me, could you repeat the question? (D) F: I agree with you. Maybe we can think about another topic because a lot of people are already doing it.
