How does Tommy's information about old schools become an intellectual challenge for Margie?

Correct answer: It changes her normal idea of education

The governing concept is a change in assumptions caused by new information. Margie has always treated home study and a mechanical teacher as normal, so she initially finds Tommy’s description of a school building, a human teacher, and many children unbelievable. As she thinks about it, she must compare her isolated routine with a completely different educational model. That mental comparison challenges her definition of school and makes her wonder whether the older arrangement was more enjoyable. Option A is correct because the information changes her basic idea of education. B, C, and D do not follow from Tommy’s account and confuse reflection with unrelated actions.
