Which feature of the old school appeals to Margie?

Correct answer: All children being together

The correct answer is A, all children being together. Margie is fascinated by the idea that pupils once went to a school building, sat together, and learned with other children of a similar age. She has never experienced this kind of shared classroom because her mechanical teacher visits her through a teaching device at home. The governing concept is the social dimension of education: companionship can create interest, cooperation, and a sense of belonging. Option B describes her lonely present, not the old school. Options C and D are unsupported, since the old school had human teachers and did not necessarily eliminate homework.
