Answer:
The sentence My little brothers like to watch "The Peppy Pirates” on TV, and they drive me crazy! contains a vague pronoun.
Explanation:
As a general rule, pronouns should clearly refer to one unmistakable noun. Vague pronouns are those pronouns that do not have a clear noun antecedent and trigger misunderstanding in the reader. The pronoun they in this sentence is not clearly linked to neither my little brothers nor "The Peppy Pirates," so it could be easily considered a vague pronoun.
