Why did Margie like the idea of the old school?

Correct answer: Because children and teacher were together

The governing concept is the social nature of traditional schooling. Margie and Tommy usually study alone at home with mechanical teachers, so their learning is private and controlled by a machine. When Margie reads about old schools, she imagines children of the same age gathering in one classroom and learning from a human teacher. This shared setting seems enjoyable because students can talk, compare ideas, help one another, and experience companionship. Hence option D is correct. Option A is wrong because old schools did include lessons; B describes isolation rather than school life; and C reverses the contrast, since old schools had human teachers, not only machines. The answer shows Margie’s curiosity about social learning.
