Who is the librarian at the school attended by Alex?

• A. Ms. Campos
• B. Ms. Johnson
• C. Ms. Patel
• D. Ms. Rivera

Answer: (A)

Identifying a specific role tied to a character’s school is what this item tests. The text names the person who works as the librarian at the school Alex attends, making Ms. Campos the correct choice because that designation directly links her to the library and to Alex’s school setting. To confirm, look for the part of the passage that introduces the librarian and describes their duties or place in the school, which will reveal Ms. Campos. The other names appear in different roles or contexts and aren’t described as the librarian, so they don’t fit the described position. When recalling such details, focus on the sentence that ties a person to a concrete job within the setting.
