Final answer:
The context required to answer the question on how EJ knows Maxine is missing from the question. Therefore, an accurate conclusion can't be drawn about the relationship between EJ and Maxine.
Step-by-step explanation:
The question doesn't provide ample context for determining how EJ knows Maxine. The paragraphs mentioned in the reference data don't specifically discuss EJ or Maxine. These mentioned characters are unrelated to the main question, which is asking about the relationship between EJ and Maxine. The possible answers (a. They are cousins, b. They went to the same school, c. They are neighbors, d. They met at a summer camp) suggest that EJ and Maxine could know each other through various circumstances, but without proper context, a concrete answer can't be provided.
