How does technology-based education affect the child's freedom?

Correct answer: The child becomes dependent on the machine's fixed pace and order

Option A is correct because Margie’s learning is organized by the mechanical teacher’s programmed schedule, lesson sequence, and testing system. Although she studies at home, this arrangement does not mean that she controls every aspect of her education. The machine determines what is taught, presents it in its established way, and evaluates her responses. Her dependence becomes especially clear when the County Inspector must open and adjust the device after it gives her repeated geography tests. Options B, C, and D introduce actions that do not occur in the story. The effect is therefore controlled independence: Margie is physically alone but educationally governed by a machine.
