What was the old book about?

Correct answer: Schools of the past

The old printed book was about schools as they existed in the past. It described children learning together in a school building under the guidance of a human teacher, which was very different from Margie and Tommy’s individual lessons at home. Option B is therefore correct. The book is not about space travel, robot wars, or farming methods; none of those subjects leads to the story’s discussion about how education has changed. Its contents are important because they make Margie imagine classmates, a shared classroom, and a teacher who is a person. The book thus serves as a contrast between older social schooling and the future system of mechanical, home-based instruction.
