The memory of old schools becomes a criticism of which lack in technology?

Correct answer: Lack of collective joy and company

The governing concept is contrast: the imagined old school highlights what Margie’s technological education does not provide. Her mechanical teacher gives immediate instruction and testing, so the story is not criticising technology for lacking instant checking. Nor does Margie lack home study or machine adjustment; those are features of her daily routine. What she lacks is a group of classmates with whom she can talk, learn, play, and share the pleasure of school. The remembered image of children studying together therefore becomes a criticism of isolation. Option A is correct because it includes both companionship and collective joy, while the other options describe services that technology already supplies or irrelevant details.
