Final answer:
In the sentence, 'The clever children ran after school,' the noun is 'children' and the verb is 'ran.'
Step-by-step explanation:
The sentence 'The clever children ran after school' contains both a noun and a verb. In this case, 'children' is the noun, which functions as the subject of the sentence. The word 'ran' is the verb, describing the action that the subject is taking. If we look at subject/verb agreement, the verb 'ran' is in agreement with the plural noun 'children,' matching in number for correct grammatical structure. This sentence also reflects how subjects can be plural nouns and that the verbs must accordingly adjust to maintain proper subject/verb agreement.
