What items were required for test takers to bring to the Monk Building?

In "The Mysterious Benedict Society," test takers were specifically instructed to bring a single pencil and a single rubber eraser to the Monk Building. This detail emphasizes the simplicity and focus of the testing environment, aligning with the theme of intellectual rigor and problem-solving that pervades the story. By limiting the materials to just a pencil and an eraser, the author highlights the idea that the true challenge lies not in having many tools or resources, but in the creativity and critical thinking of the individual taking the test. This establishes the tone and set-up for the unique challenges the characters will face.
