Answer: The sentence that does not contain an antecedent is "Adela and Geraldo went to the movies".
Step-by-step explanation: An antecedent is the word or phrase that a pronoun refers to in a sentence. Although this pronoun is generally found after the antecedent, it can also come before the antecedent. The only sentence among the options that does not include an antecedent is the first one ("Adela and Geraldo went to the movies") since, unlike the other sentences, it does not include any type of pronoun.
