Margie's boredom creates which criticism of technology-based education?

Correct answer: It can be emotionally dull and isolating

The governing idea is that education involves more than delivering information; it also includes companionship, discussion, encouragement, and shared experiences. Margie studies at home with a mechanical teacher, follows its lessons, and receives no ordinary classroom interaction. Her boredom therefore reveals a limitation of completely technology-based education: it may become emotionally dull and isolating even when the lessons are available and efficiently assessed. Option C expresses this criticism accurately. Option A is opposite to Margie’s experience, while option B describes no change shown in the story. Option D is clearly false because Margie is separated from classmates rather than kept with them.
