What balance for future education is suggested by the idea of human teachers in the story?

Technology along with human dialogue and the teacher's role

The governing concept is balanced educational use of technology. The story presents mechanical teachers as capable of delivering lessons and conducting tests, so technology can offer speed, regularity, and individual practice. At the same time, Margie's loneliness and her fascination with old schools show that machines cannot fully provide companionship, spontaneous discussion, empathy, or flexible encouragement. Thus option D is correct: future education should combine useful technological tools with human dialogue and the teacher's judgment. A is too extreme because the story exposes the limitations of machines. B and C do not answer the question about an educational balance and unnecessarily reject modern learning or social contact.
