What can be considered the biggest benefit of technology in the story?

Convenience of studying at home and receiving instant checking

The educational technology in the story allows children to study at home without travelling to a common school. The mechanical teacher can present lessons, give exercises, and check answers immediately, making the process convenient and efficient. For this reason, option A is the best answer. Option B is incorrect because machine-based education isolates children instead of increasing their classmates. Option C is the opposite of the situation: Margie has a mechanical teacher and does not enjoy human closeness during lessons. Option D is also incorrect because technology has replaced printed books with telebooks, while Tommy’s paper book is treated as an unusual object from the past. The benefit is practical convenience, not social warmth.
