From the conversation, we learn that the cost of the new wing [originaltext]W: W

W: Wonderful! I spent most of my time at the art museum. I especially liked the new wing. I was amazed to hear the guide explain the problems they had building it.
M: Right. I just read an article that went on and on about the cost—(7) 90 million total I think.
W: Yeah. The guide mentioned that. You could see they spared no expense.
M: It looked really unusual, at least from what I saw in the picture.
W: It is. The basic design is two triangles. (8) In fact there are triangles all over, the paving stones in the courtyard, the skylights and even a lot of the sculptures. One sculpture is a mobile. It’s in the courtyard and it’s made of pieces of aluminum that moves slowly in the air. It’s really impressive.
M: That was in the article too. (9) It was said that the original was steel and it weighed so much that it wasn’t safe to hand.
W: Right. They did it over in aluminum so it wouldn’t come crashing down on someone’s head.
M: You know the article went into that in detail. There was even an interview with the sculptor.
W: [10] I’d like to read that. Would you mind if I borrow the magazine sometime?
M: No. I wouldn’t mind if I haven’t thrown it out yet.
