The
prepositional phrase “on the park bench” acts as adjectival phrase. Woudl be your answer :)
The correct analysis of the sentence implies that the prepositional phrase "on the park bench" acts as an adjectival phrase. This is so because the PP (prepositional phrase) modifies a noun "man". The noun head of the NP is modified by an AdjP and the PP acting as an adjectival phrase ("kindly old" and "on the park").
