【正确答案】 D

【答案解析】[听力原文] W: Hello, Tony. I remember that you wrote a paper about Albert Kahn last semester. M: Yes, for my history of architecture class. W: Oh, I'm taking it now and I have to do some research on industrial architecture, and I need to read up on Kahn's factories. So I would like to know what you have written about them. M: I don't think my paper will be helpful to you because what I focus on is his classical design, but you are interested in the modern buildings that he is famous for. W: Yes, he is known for his factory, especially the auto plants in Detroit. He made a breakthrough in industrial design. You know before his time, factories were quite inefficient. However, his factory provided enough light and air and open space. So the cars could be assembled in one huge factory. M: I remember reading about that before. Factories were wooden framed and the heavy machinery made the buildings vibrate and there were fire hazards too. But when Kahn started to design auto plants around the turn of the century, reinforced concrete had just been invented. So, both the stability and fire proofing of the buildings are considered as breakthroughs in the history. W: You seem to know a lot about his industrial career. M: Actually when I wrote about his works, I did a lot of background reading. Let me see if I can dig up that paper for you. There were some books of articles included in my bibliography that you might want to look up at the library. Why is the woman interested in the man's paper about Albert Kahn?
