E instead of D?

I was able to narrow this down between D and E. I see the previous post explaining why E is correct. Can we go over why D is incorrect? I thought "All the books in the library have their proper shelf locations recorded in the catalog" was a generalization here. Thanks!

@lerondagates,

The issue with (D) is that even if we characterize the first sentence as a generalization, the argument never rejects it. The argument is not saying "the books thus must have their locations misrecorded in the catalogue." The conclusion only relates to the book. Taken the premise that all books are recorded in the catalogue properly as true, the book that is missing must be misplaced or stolen. This conclusion is consistent with the fact that the all the books are properly recorded in the catalogue still, but the person shelving made a mistake or someone stole it.

Let me know if this makes sense and if you have any further questions.
