Final answer:
The italicized words function as verbs in certain provided sentences, and subject/verb agreement rules help ensure grammatical correctness in sentence construction.
Step-by-step explanation:
The task presented involves analyzing sentences to determine whether the italicized words function as verbs. After a careful review of the sentences provided, the determination can be made that in sentence (b) "conceive" is being used as a verb where the subject is able to conceive of ideas, in sentence (d) "analyzes" is a verb describing the action someone with an incisive mind takes on problems, in sentence (e) "advocated" serves as a verb for the group's action towards Congress, and in sentence (h) "agitate" is the action the bully uses onto someone else. The italicized words function as verbs representing actions taken by the subjects in the sentences.
Subject/verb agreement is essential to ensure sentences are grammatically correct. For example, in the sentence "The play comes highly recommended," the subject 'play' is singular, thus the verb must also be in its singular form 'comes.' Likewise, prepositional phrases, such as "with such true witticisms and parables," must not confuse the proper verb agreement, as they do not serve as the subjects of the sentences.
