From which experience does technology distance childhood in the story?

Correct answer: From the experience of learning and laughing with classmates

The governing concept is the social dimension of childhood. Margie and Tommy live in a future where children usually study separately at home with mechanical teachers and telebooks. As a result, they have little experience of sitting with classmates, discussing lessons, helping one another, or laughing together during school hours. Option A is correct because the story suggests that technology has removed this shared and joyful part of childhood. Options B, C, and D are features of the technological system itself, not experiences from which childhood is distanced. The criticism is balanced: home lessons and machine checking are convenient, but they cannot replace the friendships and informal learning created by a common schoolroom.
