01 In Margie's time, where was study mostly limited?
Answer and explanation
Correct answer: D. In the schoolroom at home
Explanation: The correct answer is D: study took place in the schoolroom at home. Margie did not travel to a common school building; instead, her mechanical teacher was installed in a room of her house. This arrangement made education individual and home-based, with the learner receiving lessons alone from a machine. Option B describes the old system that Tommy and Margie discuss, not Margie’s own time. A playground is for recreation, not the regular location of her lessons, and the story does not present a public library as her classroom. Thus, the home schoolroom is the clearest sign of the future educational system.
