What is the simplest message about technology in education in the story?

Correct answer: Technology is useful, but human companionship is also necessary

The governing idea is balance: educational technology can make lessons regular, personalised, and efficient, but it cannot provide every human benefit of a school. Margie receives instruction from a mechanical teacher, and the machine can test her work immediately. Yet she becomes fascinated when Tommy explains that children once studied together with human teachers. She imagines the fun of sharing lessons and companionship. Thus option A gives the story’s simplest and most accurate message. Option B is too extreme because technology does not remove the value of people; C makes an unsupported claim of complete superiority; and D is false because the printed book is central to the children’s discovery.
