Why does the importance of human teachers become a criticism of futuristic education in the story?

Correct answer: Because future education appears emotionless and lonely

The story presents futuristic education as efficient but emotionally limited. Children receive lessons from machines at home, yet they miss the companionship of classmates and the personal care of a human teacher. Margie’s loneliness and her interest in the old schools show that convenience alone does not make education complete. Learning also involves conversation, encouragement, shared experiences, and an understanding of a child’s feelings.

Therefore, option A is correct: future education appears emotionless and lonely. This is a criticism of technology when it replaces human contact instead of supporting it. The other choices are not central to the story: it does not mainly criticise expensive books, children’s refusal to attend school, or the absence of history as a subject.
