What contrast is highlighted by Margie's distance from her machine and desire for old schools?

Correct answer: Even with convenience, education may feel incomplete without humanity

Margie's dislike of the mechanical teacher and her interest in old schools create an important contrast. The machine offers convenience: lessons are available at home and answers can be checked efficiently. Yet Margie imagines children learning together with a human teacher, and that picture attracts her. It suggests that education is not complete merely because information is delivered quickly; companionship, communication, and warmth also matter.

Option A is correct because it expresses the contrast between convenience and humanity. The story does not say that old schools had no children, that machines always made children happy, or that home learning was always collective. Margie's feelings show that a technically efficient system may still seem empty when it does not provide the social and emotional experiences associated with human schooling.
