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. ,F: Well, how about water pollution? ,M: Yes, I've heard that it is a serious problem. Do you have any information about it? ,F: I think we have several books over there. ,M: Thanks a lot.
(A) F: Great, so your project will be greenhouse effect. Hope you can enjoy it. (B) F: Excuse me, could you repeat the question? (C) F: Great, so your project will be noise pollution.
