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

Correct answer: 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.
