Here is the sentence:
My grandmother doesn't trust banks, so she has __________ money all over
the house. Once, I pulled an old Reader's Digest off a shelf and
found seven $100 bills stuck between the pages.
The blank requires the past participle of hide, an irregular verb. You chose hidden, the correct form. Good job!
