The pronoun and antecedent are not in agreement in the following sentence: Everybody needs to call its parents.
Explanation:
Pronouns are words used to take the place of nouns. The word for which a pronoun stands for is called <em>antecedent.</em> In this case, the pronoun "it" refers back to the indefinite pronoun "everybody". However, everybody is an indefinite pronoun referring to people, so "it" cannot take its place. The personal pronoun "it" is used to refer back to things or animals. That is why there is no pronoun- antecedent agreement in the sentence.
