How does a human teacher make knowledge a living tradition in the old school?

He passes knowledge through dialogue and experience from one generation to another

The governing concept is that a tradition remains alive when knowledge is transmitted through people, interpretation, and continued participation. A human teacher does more than repeat information: the teacher explains, answers questions, relates lessons to experience, and adapts ideas for a new group of learners. In this way, knowledge moves from one generation to another while remaining meaningful and open to discussion. Option A is correct. Option B belongs to machine maintenance, not teaching; option C removes the dialogue necessary for understanding; and option D rejects the books that provide important knowledge. The old school therefore represents continuity combined with human interaction.
