What is Mr. Lemoncello's role in the story?

• A. A Rival Contestant
• B. A Librarian
• C. Owner and Designer of the Library
• D. A Security Chief

Answer: (C)

Mr. Lemoncello is the library’s owner and the designer of the whole project. He’s the eccentric game-maker who builds the high-tech, puzzle-filled library and launches the big competition inside it. The story frames him as the mastermind behind the library—funding, creating, and presenting the challenges for the contestants—so his role as owner and designer is the best fit. He isn’t just a rival contestant, nor the librarian who keeps the day-to-day shelves running, nor the security chief; those other roles belong to different characters or functions within the library setting.
