Question says → You hear

Why: He collected maps and data to make a route book, and explains that it shows the route they took. The note uses the same verb, prepare, so route book drops straight in.
The trap: Maps is said first, but those were what he collected to make the book. 'Prepared a maps' also breaks the grammar.
