What is the pronoun and antecedents in sentence Elizabeth Cochrane had a special goal succeeded reaching it?

Let's break down the pronoun and antecedent in the sentence:

* Pronoun: "it"

* Antecedent: "a special goal"

The pronoun "it" refers back to the noun phrase "a special goal." This means "it" is a referential pronoun and "a special goal" is its antecedent.
