Correct answer: A. With classmates
Explanation: The governing idea is that highly mechanised education can provide instruction without providing companionship. Margie studies alone at home with a mechanical teacher, so she does not share lessons, questions, play, or conversation with classmates. Technology connects her to a screen and an automated teaching system, but it separates learning from the social experience of a classroom. Therefore, option A, “With classmates,” is correct. Option B is unsuitable because technology actually connects her with machines, option C is the opposite because she uses a screen, and option D is not a meaningful contrast in the story.
