Besides lessons, what did old teachers give children?

Correct answer: Guidance

The governing concept is that teaching includes guidance, not merely the delivery of academic content. In the story’s imagined old school, a human teacher could explain a difficult idea, observe a child’s response, correct mistakes, answer questions, and advise the learner about how to improve. This continuing personal direction is guidance. Therefore option A is correct. A blank screen, machine sounds, and a lonely room are associated with the impersonal or isolated features of mechanical learning, not with what a helpful teacher gives. The question also reinforces the central contrast of the chapter: a machine can present lessons efficiently, whereas a human teacher can shape understanding through conversation, judgement, encouragement, and individual attention.
