W: Excuse me, I’ve been using this old book for a research project and I notice that a lot of pages are turning brown and becoming brittle.
M: Yes. Unfortunately, that’s a common problem with books made from wood pulp.
W: I suppose that to make paper from wood you have to add a lot of chemicals and acids to make it turn white.
M: Exactly, and it’s the acid that eventually eats away the paper:
W: Oh, that actually makes sense, but this book’s not even 75 years old and I’ve seen books in museum that are hundreds of years old and they’re in free condition.
M: Well, you see, books have been made from wood pulp only since the 1850s, before that they were made from materials mostly animals’ skins, and no chemicals were added.
W: It’s a shame those older wood pulp books are going to fall apart some day. Is there anything that can be done to preserve them?
M: Eh, currently the only way to stop the books from decaying is to remove the binding and treat each page individually to remove the acid.
W: That doesn’t sound very economical.
M: No, it isn’t. It’s not practical to treat a large number of books with this process, so we only try to rescue the most valuable edition books in our collection.
W: Well, thanks for the explanation. I’d better get back to my project.
M: Good luck and I hope the old book will hold long enough for you to finish it.

综合推断题:女士认为用木材制纸时要往里面加一些化学制品和酸性物质以让纸变白,而男士说最终腐蚀纸张的就是这些酸性物质,由常识可推断出这类酸性物质也应是化学制品,即男士认为书籍的腐烂是由化学制品造成的,故选B。
