Who is Alex's school librarian?

• A. Ms. Campos
• B. Ms. Martinez
• C. Mrs. Kim
• D. Ms. Rivera

Answer: (A)

Matching a character to the librarian role based on explicit references in the text. In this scenario, the story introduces the person who helps Alex with books and library tasks as Ms. Campos, who is described in connection with the library itself. That direct link—Alex interacting with Ms. Campos in the library and being guided or assisted there—identifies her as the school librarian. The other names may appear as staff or classmates, but they aren’t described as the librarian, so they don’t fit the role. When answering, look for the instance where the librarian is named in relation to library activities or is labeled as “the librarian,” and that tells you which person holds the position.
