Which of these sentences has a missing antecedent?
Although my sister is a swimmer, I don't know anything about it.
When Trina and Rachel went to the mall, she drove.
To find which of these sentences has a missing antecedent, we need to understand what an antecedent is. An antecedent is a noun or pronoun that a pronoun refers to. In other words, an antecedent is the noun that comes before the pronoun and gives it meaning.
Let's examine the first sentence: "Although my sister is a swimmer, I don't know anything about it." Here, the pronoun "it" does not have a clear antecedent. We can assume that "it" likely refers to swimming, but since there is no explicit antecedent for "it," the sentence has a missing antecedent.
Now, let's look at the second sentence: "When Trina and Rachel went to the mall, she drove." In this case, the pronoun "she" does have a clear antecedent. The pronoun "she" refers to one of the two previously mentioned individuals, Trina or Rachel. Even though we don't know exactly which one drove, the antecedent is still present, so this sentence does not have a missing antecedent.
Therefore, the sentence that has a missing antecedent is: "Although my sister is a swimmer, I don't know anything about it."
