Final answer:
A prepositional phrase starts with a preposition and modifies a word. 'Taking a break' is not a prepositional phrase due to the lack of a preposition.
Explanation:
A prepositional phrase starts with a preposition and modifies or describes a word. It cannot act as the subject of a sentence. Examples include 'in order to,' 'on the hour,' and 'taking a break.'
In this case, the prepositional phrase that is NOT a prepositional phrase is taking a break as it lacks a preposition to make it a complete prepositional phrase.
