Question

Click the noun or noun phrase that's modified by the prepositional phrase in bold.

Perry the Platypus thought he saw a martian in the cave behind
a
the school.

Answer 1

If the bolded is "Behind at the school" the answer is cave.

Step-by-step explanation:

A prepositional phrase is a phrase that starts with a preposition and ends with a noun. A preposition is a word or a group of words to either show direction, time, place, or to introduce something. So cave modifies " behind the school" because it tells us what is behind the school.
