What is the most different feature of future education in the story?

Correct answer: Study at home with a machine

The correct answer is A because the story presents future education as individual study at home with a mechanical teacher. Margie does not travel to a school building or sit beside other children; instead, the machine delivers lessons, gives tests, and adjusts instruction according to her performance. A blackboard, school prayer, and playground are familiar features associated with conventional schools, not the unusual future arrangement described in the story. The governing concept is the impact of technology on the structure of education. The author does not simply praise or condemn the machine; rather, the contrast invites readers to consider whether convenience and automation can replace human contact and shared classroom life.
