Question

on the survey, twenty people preferred reading. subject direct object predicate nominative

Explanation:

To determine the part of speech for "twenty people" in the sentence "On the survey, twenty people preferred reading", we analyze the sentence structure. The subject of a sentence is the person, place, thing, or idea that is doing or being something. Here, "twenty people" is the entity that is performing the action of "preferred", so it functions as the subject. The "direct object" would be what is being acted upon (here, "reading" is the direct object of "preferred"), and "predicate nominative" is a noun or pronoun after a linking verb that renames the subject, which is not the case here.

Answer:

subject
