Why is Margie not satisfied despite the convenience given by technology?

Correct answer: Because convenience lacks human company and joy

The correct answer is B. Technology makes Margie’s education convenient: she studies at home, receives scheduled lessons, and gets her answers checked quickly. Yet convenience alone does not create satisfaction. She has no classmates beside her, no human teacher with whom she can share feelings, and no group experience of learning and play. Her interest in the old book reveals that she longs for the social joy associated with traditional schools. Option A is false because the machine does give lessons. Option C is false because she has access to telebooks. Option D is false because the County Inspector only repairs the machine. The story contrasts practical convenience with emotional fulfilment.
