How is the biggest paradox of future education expressed in the story?

Correct answer: Learning is more personalized but the child is more lonely

The future system is advanced because the mechanical teacher can provide lessons at Margie’s individual level and deliver instruction conveniently in her home. Yet the same personalization removes the shared environment that gives education a social and emotional dimension. Margie has no classmates, no common activities and no human teacher with whom she can form a learning relationship. The story’s paradox is therefore that greater technological personalization does not necessarily create a richer educational experience; it may produce deeper loneliness. Option A states this contrast precisely. Option B is meaningless, option C is internally contradictory because the teacher is mechanical rather than human, and option D does not describe the educational issue developed in the story.
