What does the old teacher explaining lessons indicate?

Human adaptability in teaching

The governing concept is responsive teaching. A human teacher does not merely present a fixed sequence of information; the teacher can notice confusion, listen to questions, change an explanation and use examples suited to the learners. In the story, the old form of schooling suggests direct interaction between children and a teacher who explains lessons in person. That flexibility allows instruction to respond to different abilities and doubts. Therefore, option A is correct because it identifies human adaptability as a strength of teaching. Option B is the opposite of the episode, since the story questions mechanical rigidity; option C blames books even though books can support learning; and option D unfairly attributes the educational contrast to student laziness rather than to the teaching system.
