Why does imagining old children studying together give Margie satisfaction?

Correct answer: Because she sees an alternative to her loneliness

The governing idea is that education is not only the delivery of lessons; it also includes companionship, discussion and shared experience. Margie studies alone at home with a mechanical teacher, so learning has become an isolated routine. When the County Inspector repairs the machine, she reads about old schools in which children gathered together and were taught by a human teacher. She imagines classmates learning, talking and helping one another, and this vision makes school seem enjoyable. Therefore, option C is correct: the imagined classroom offers an alternative to her loneliness. Option A is opposite to her feeling, option B is not the reason for her satisfaction, and option D is impossible because Margie belongs to the future.
