When children find the old school strange, what does it prove?

Correct answer: Technology changes the definition of normal experiences

The governing concept is the changing meaning of normality because technology transforms everyday life. In the story, Margie and Tommy have grown up with mechanical teachers and lessons delivered at home, so the idea of children studying together in a shared school seems unusual to them. Their reaction does not prove that old education was unreal, that children hate history, or that curiosity will disappear. Instead, it creates a perspective shift: a system that was once ordinary has become strange in the future. Therefore, option D is correct because technological change can redefine familiar experiences without removing the human value of those experiences.
