The man riding the old, beat-up bicycle wore a fancy yellow hat. The man was wearing a fancy yellow hat when he left his house. Wearing a sheepish grin, the man rode his bicycle in the middle of the street.

Answer 1

The man with the fancy yellow hat rode an old, beat-up bicycle.
"With the fancy yellow hat" is a prepositional phrase, and it is describing the man who is wearing it. Who? The man with the fancy yellow hat.

Answer 2

The sentence in which the prepositional phrase functions as an adjective is the first one. "The man with the fancy yellow hat rode an old, beat-up bicycle."

This is the sentence that has a preposition, which is key to notice an prepositional phrase. The preposition is WITH. Prepositional phrases tend to end with a noun, pronoun, gerund, or clause, the "object" of the preposition.In this case it ends with HAT, a noun.

In this case it functions as an adjective as it is describing the subject of the sentence; "the MAN."
