Through what is the real lack in education revealed in the story?

Correct answer: Through Margie’s dull study and desire for old schools

The governing method is characterisation: the story reveals an educational weakness through Margie’s feelings and reactions rather than through a direct formal argument. Her lessons are conducted alone by a machine, and the routine becomes dull even though the system is technically advanced. After seeing the old book and hearing about schools where children learned together, she begins to desire that unfamiliar experience. This combination of present boredom and imagined companionship exposes the real lack: education has lost social interaction and emotional engagement. Option A is therefore correct. Tommy’s age is a minor fact, attic dust is merely setting, and the word Geography identifies a subject in which Margie struggles; none of these independently reveals the central educational deficiency. The evidence lies in Margie’s experience and longing.
