On the basis of joy in learning, who appears better between a human teacher and a machine teacher?

Correct answer: The human teacher

The governing idea is that learning is also a social and joyful experience, not merely the completion of programmed exercises. In the story, Margie’s mechanical lessons are solitary and routine, whereas Tommy’s description of old schools suggests that children studied together, helped one another, and enjoyed the presence of a human teacher. This shared environment gives learning warmth and companionship. Therefore, option A is correct: the human teacher appears better when the criterion is joy in learning. A broken machine and a blank screen cannot teach effectively, and the county inspector repairs or evaluates the machine rather than functioning as the regular teacher. The contrast makes Margie curious about old-style schooling.
