There is a prepisitional phrase at the end of each sentence. Are these adverbial phrases or adjective phrases?

Hmmm. I think it is clear that the are all adverb phrases. They answer the question "where?"

I agree with Steve.

To determine whether the prepositional phrases at the end of each sentence are adverbial phrases or adjective phrases, we need to understand the function of these phrases in each sentence.

1. "in the street" - This phrase indicates the location where he met a lot of people. It modifies the verb "met" and answers the question "Where?" Since it modifies the verb, it is an adverbial phrase.

2. "at the market" - This phrase indicates the location where he greeted some people. It modifies the verb "greeted" and answers the question "Where?" Like the previous example, it modifies the verb, so it is an adverbial phrase.

3. "on the corner" - This phrase indicates the location where he talked to a person. It modifies the verb "talked" and answers the question "Where?" Again, it modifies the verb, making it an adverbial phrase.

4. "on the street" - This phrase indicates the location where he found the boy. It modifies the verb "found" and answers the question "Where?" It modifies the verb, so it is an adverbial phrase.

5. "on the sidewalk" - This phrase describes the location where he saw a beggar. It modifies the verb "saw" and answers the question "Where?" Hence, it modifies the verb and is an adverbial phrase.

In summary, all of the prepositional phrases at the end of each sentence are adverbial phrases because they modify the verbs and provide information about location in each sentence.
