Which final effect of the story best explains the need for human teachers?

The reader feels the lack of joy, relationship and sharing in learning

The governing concept is the story’s contrast between efficient individualized instruction and the richer social experience of a human classroom. By the end, Margie begins to imagine children learning together, laughing and helping one another under a human teacher. This imaginative response makes the reader feel what mechanical schooling lacks: companionship, shared enjoyment, emotional connection and a sense of belonging. Option B is therefore correct. Option A is wrong because an old school is not presented as a machine. Option C reduces the story to one subject, while option D ignores the story’s criticism of an isolated technological future. The ending creates appreciation for human teachers through emotional contrast rather than direct argument.

This is a Class 9 English question. Chapter: The Fun They Had. Topic: the importance of human teachers.
