Which part of education in the story matches today's schools?

Correct answer: Group classroom in old schools

The correct answer is A. A group classroom, where many students learn together under the guidance of a teacher, resembles the ordinary school experience familiar today. In contrast, Margie's mechanical teacher, her lessons at home, and the system of entering answers through a special device belong to the story's imagined future. The comparison is important because the narrative makes familiar schooling appear unusual to Margie, while readers recognize it as normal. The old classroom also offers interaction and shared activities, which help explain the title and the idea that earlier children may have found learning more enjoyable. Therefore, the group classroom is the matching feature.
