Pronouns and Antecedents

This error is a bit unusual. Generally, the opposite error arises. Grammatically speaking, the pronoun and its antecedent do not agree. A pronoun is a word that replaces a noun. The antecedent is the word the pronoun replaces. For example, The boy brought his favorite toy, and he left it in the car. The pronoun is the word "he." It replaces the word "boy." "Boy" is the antecedent. "He" is singular and masculine. "Boy" is singular and masculine; therefore, they agree. In the example in the photo, the pronoun is "his." "His" is singular and masculine. The antecedent of the pronoun is "People." "People" is plural; therefore, the pronoun and antecedent do not agree.
