M: Hey, Jane. What do you think of the art museum you visited last week?
W: It is wonderful, especially the new wing.
M: I have just read an article about that new wing and it says the cost is ninety million total. It’s amazing, I think.
W: Yeah, the guide mentioned that. You could see they built it at all costs.
M: Hmm. It looks really unusual, at least from what I saw in the picture.
W: It’s really impressive. There are triangles all over the paving stones in the courtyard, the skylights, and even a lot of the sculptures. All the sculptures are mobile and are made of pieces of aluminum that move slowly in the air. You’ll like it, I bet.
M: The article said that, too. It was said the original was steel, and it weighed so much that it wasn’t safe to hang.
W: Right. They used aluminum later so that those sculptures wouldn’t come down on someone’s head.
M: From the article, I also learned there appeared many other problems when they built it.
W: The article sounds interesting.
M: Yes, it went into every detail about the new wing. There was even an interview with the sculptor.
W: I’d like to read that. May I borrow your magazine?
M: Of course. Just come to my place and take it tonight.
