How does technology turn education into a controlled experience in the story?

Correct answer: The machine fixes the lessons, pace, questions, and assessment.

The governing concept is technological control over the learning process. Margie studies with a mechanical teacher whose lessons are inserted according to a schedule, whose speed can be adjusted, and whose questions and tests are produced and assessed by the machine. Her performance is treated as data that requires technical correction rather than as the starting point for a flexible human discussion. Thus, option C is correct because it includes the major forms of control: content, pace, questioning, and evaluation. Option A describes the opposite of Margie’s experience, B reverses the direction of control, and D has no logical connection with the machine’s educational function.
