Your question is incomplete because it does not provide the underlined words, which are the following:
- The suggestion that Jim run for student body president was greeted with enthusiasm.
- Jim's uncle, the former mayor, helped him plan his political campaign.
Answer:
- adverb phrase
- appositive phrase
Step-by-step explanation:
Adverb phrases function as adverbs and modify a verb, adjective or another adverb. Thus, the phrase with enthusiasm describes how the verb was greeted is performed.
On the other hand, appositive phrases contais an appositive and modifiers, and gives identity to or labels a noun or pronoun. As a result, the appositive phrase the former mayor modifies the noun phrase Jim's uncle.
