In Margie's experience, technology turns learning into what kind of activity?

Correct answer: Private and repetitive practice

The governing concept is the individualisation and mechanisation of learning. Margie receives lessons from a mechanical teacher installed in her home, and the machine presents exercises, checks her answers, and gives her tests without classmates participating. Her routine therefore becomes private and repetitive rather than social or exploratory. A public celebration, group play, or open debate would require interaction with other learners, but the future system described in the story isolates the child from that shared experience. Option C is correct because it combines the two central features: Margie studies alone, and the machine repeatedly assigns programmed exercises. The answer also helps explain why she becomes curious about the old kind of school mentioned in Tommy’s book.
