What idea about human teachers is formed through Tommy and Margie's conversation?

Correct answer: A teacher can make the class a shared experience

The governing idea is that education is not only the delivery of information; it is also a social and human experience. Tommy and Margie live in a future where a mechanical teacher teaches one child at home, but an old printed book makes them imagine children sitting together in a classroom with a human teacher. Such a teacher could explain ideas aloud, respond to questions, encourage participation, and create a feeling of companionship. Their conversation therefore suggests that a human teacher can turn a lesson into a shared experience rather than a lonely, fixed routine. Option A is correct. Options B, C, and D contradict the story: human teachers communicate, do not merely repair machines, and help learning continue.
