Identify the choice that best describes the underlined word or phrase for questions 1–2.
The suggestion that Jim run for student body president was greeted with enthusiasm.
adverb phrase
adjective
appositive phrase
gerund phrase
The underlined word or phrase (which unfortunately I can't see since it's not indicated in the text) refers to "Jim run for student body president." This phrase is a noun phrase acting as the subject of the infinitive "to suggest." It is not an adverb phrase, as it does not modify a verb, adjective, or another adverb. It is not acting as an adjective since it is not modifying a noun. It is not an appositive phrase because it is not renaming another noun.
Instead, the phrase is best described as a gerund phrase, as it features the verb "run" used as a noun, with "Jim" as its subject. In this sentence, the gerund phrase is the object of the suggestion, indicating the action that was proposed. Therefore, the correct description is:
gerund phrase
