What did the old book make Margie think about?

Correct answer: About the fun of old schools

The correct answer is A. The old printed book describes children learning together in a school, and this makes Margie imagine how different their daily experiences must have been. She begins to think about classmates, a human teacher, shared lessons, and the possibility that children could enjoy learning as a group. The book does not make her think about cooking or space warfare, and the County Inspector's job is only connected with repairing her mechanical teacher. The governing idea is the contrast between communal education in the past and isolated technological instruction in the future. This contrast also explains the title, because Margie starts to understand the fun that old schools may have offered.
