Why was the human teacher important for children in the old school?

Correct answer: He was the person who explained and created dialogue in class

The governing concept is face-to-face teaching and classroom dialogue. In the old school, a human teacher directly explained ideas, responded to children’s questions, observed their progress, and guided interaction among classmates. This made learning a shared activity rather than an isolated exchange with a machine. Option C is correct because it captures both explanation and dialogue, the two central functions described by the question. Option A is wrong because separation would remove cooperation. Option B confuses teaching with technical repair, and option D contradicts the purpose of a teacher. The story presents the old school as valuable not because it lacked technology, but because children learned through personal contact, conversation, and collective participation.
