Which antecedent agrees with the pronoun in this sentance

To determine which antecedent agrees with a pronoun in a sentence, you need to identify the pronoun and then find the noun or pronoun it is referring to. The antecedent is the noun or pronoun that precedes the pronoun and agrees with it in terms of number (singular or plural) and gender (masculine, feminine, or neuter).

However, as you haven't provided the sentence or the pronoun in question, I am unable to give you a specific answer. Could you please provide the full sentence and the pronoun you are referring to, so I can assist you better?
