What does Margie's boredom tell about technology-based education?

Correct answer: It can be emotionally dull

The governing concept is that educational effectiveness includes emotional engagement, not merely the delivery of information. Margie’s mechanical teacher gives lessons and checks her work, but she finds the experience dull because she studies alone without the lively presence of classmates or the warmth of a human teacher. Her boredom therefore reveals a limitation of technology-based education: it may be efficient and individualized while still feeling emotionally empty. Option D is correct. Option A makes an absolute claim contradicted by Margie’s experience, B falsely says the machine gives no lessons, and C introduces paper books even though the machine uses electronic instruction.
