Which aspect of education became more private because of technology in the story?

Correct answer: Place and experience of learning

The governing idea is that technology has moved education from a shared school environment into an individual home setting. Margie receives lessons in a room inside her house from a mechanical teacher, and she studies without classmates sitting beside her. Therefore, both the physical place of learning and the personal experience of learning have become private. Option A is correct because it captures this wider change. Option B is only a detail about the old printed book, while option C concerns repair and not the social form of education. Option D is merely the location where Tommy finds the book and does not describe the educational change. The story also suggests that private convenience may reduce the warmth and companionship of traditional schooling.
