Câu hỏi: a. Huh. Looks like a couple of other folks've left their books in here, too. Why don't they put them back where they got them when they're through, anyway? b. Yeah, I guess. I've done that, too. How about, um, "Engineering Basics"? Is this it? It's not green, though. It's kind of, uh, turquoise?c. Nope. Just a couple of works on Anglo-Saxon grammar....d. Sure. What's the title?e. Could you just take a look in the shelf for me? f. Uh..."Fundamentals of Bioengineering" or something like that- I forget the exact title. (laughs) That's why I need it! It's a sort of green paperback.g. Huh! That's kind of eerie, isn't it? That's really pretty close. No, not mine. Nothing else there? h. Probably just forgot, like me. It's easy to forget a book in there after you've been sitting here going through books for three or four hours at night.
