How does the feeling implied in the title become clear at the end of the story?

Correct answer: Margie imagines the fun children had at school in the past

The governing literary concept is the connection between a title and the story's concluding insight. After Tommy describes old schools, Margie imagines children learning together in a building, meeting a human teacher and spending time with classmates. Although she has never experienced that system, she begins to see that it included conversation, friendship and shared enjoyment that her solitary lessons lack. Her final thought that the children must have had fun gives the title its meaning and creates gentle irony: the supposedly advanced future may be less joyful than the past. Option A is correct; the other events do not occur.
