Why does the value of a human teacher increase in the story?

Because a human teacher provides personal guidance and social interaction to children

The governing concept is the difference between efficient instruction and complete education. Margie and Tommy study at home with mechanical teachers, which can deliver lessons and test answers, but they do so in isolation. Their discovery of old schools reveals the value of studying with other children and receiving personal attention from a human teacher. A human teacher can interpret responses, encourage effort, answer unexpected questions, and build social relationships. Therefore, option A is correct. Option B is false because the mechanical teacher can teach lessons; its limitation is that it cannot replace human companionship and responsive guidance. Options C and D have no meaningful connection with the story’s central idea.
