01 What was one benefit of the machine teacher?
Answer and explanation
Correct answer: A. It checked answers quickly
Explanation: The machine teacher in “The Fun They Had” was programmed to give lessons, set exercises, and check answers rapidly. Its technological design allowed Margie’s work to be assessed immediately, so option A is the correct benefit. Quick checking can provide prompt feedback and allows the machine to adjust or continue the lesson without waiting for a human teacher to mark notebooks. The other options do not describe its role in the story: it did not send children to the old school, it was not a printing press for paper books, and it could not create real classmates or the social experience of a classroom. The story presents this speed and individualised instruction as a practical advantage, while also suggesting that efficient machinery cannot fully replace human companionship and shared learning.
