Because of the human teacher what kind of activity was study in the old school?

Correct answer: Shared activity

The governing concept is the social nature of classroom learning. In an old school, a human teacher brought several children together, guided their work, answered questions, and encouraged communication. Study therefore became a shared activity involving participation and companionship, not merely a private exchange with a machine. Option A is correct because it captures this collective character. Option B belongs to the future mechanical arrangement, while C and D contradict the presence of classmates, conversation, and teacher-led interaction. The answer also explains why Margie and Tommy find old schools attractive and unusual.
