Which difference between Margie and Tommy helps us understand the value of human teachers?

Correct answer: Both show different kinds of curiosity about old schools

The governing method here is character comparison. Margie initially finds the old school strange and is especially interested in the idea of a human teacher, while Tommy, who is older and more familiar with the book, explains that children once learned together in a school building. Their different reactions make the reader examine what has disappeared from future education: shared classrooms, human contact, and curiosity about one another’s experience. Option A is correct because their responses to the old school illuminate the value of human teaching. Options B, C, and D are factually wrong: they do see a book, they do not study daily with human teachers, and they live at home rather than in a school building. Their conversation develops the central theme.
