Ok, I understand this, thanks. But there's something else I'm wondering too.

Suppose I take the sentence {puqvaD paq luyajmoH ghojmoHwI'} and rewrite it omitting the {puqvaD}:

paq luyajmoH ghojmoHwI'

Could this new sentence mean too "the teachers cause someone unspecified to understand the book"?

Or is that the only thing it can mean is "the teachers cause the book to understand" as if the book was alive or something?
