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

Correct answer: 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.
