What change occurs in Margie's thinking after learning about old schools?

Correct answer: She begins to see education as more social

The correct answer is A. Before reading Tommy's book, Margie accepts her isolated machine lessons as normal, even though she dislikes the geography tests and the mechanical teacher. Learning that children once went to a building, studied together and were taught by a human makes her reconsider what education can be. She imagines classmates learning and playing with one another, so schooling begins to appear social, lively and enjoyable rather than merely individual and automatic. She does not stop studying, discard her telebook or become a County Inspector; those choices are unsupported by the narrative. The important change is an expansion of her understanding: she recognizes the human and communal dimension of learning.
