01 What social change is suggested by Margie's home-based education?
Answer and explanation
Correct answer: A. Children becoming separated from collective school
Explanation: The governing idea is that technology has changed not only the teaching method but also the social setting of education. Margie studies alone at home with a mechanical teacher, so she does not meet classmates, share activities, or learn through ordinary face-to-face interaction. This suggests a movement away from the communal school toward isolated, individualized learning. Therefore, option A is correct. Option B is unrelated to the school system, while C and D are absurd alternatives with no connection to the story. The contrast also helps readers notice that technological efficiency may come at the cost of companionship and a shared school experience.
