Why does Margie see joy in the idea of old schools although she has never been there?

Because she is dissatisfied with her present lonely and mechanical study

The governing idea is that imagination can arise from dissatisfaction and comparison. Margie has never attended an old-fashioned school, yet the book's description allows her to compare that possible experience with her own lonely routine. She studies alone, receives lessons from a machine, and has no classmates with whom she can share questions or enjoyment. Consequently, the thought of children learning together seems exciting and joyful to her. Option C is correct because it links her positive imagination to dissatisfaction with mechanical isolation. A, B, and D are unsupported: her speed, the book's price, and freedom from examinations do not explain her attraction to old schools.
