What can a human teacher do by listening to a child?

Correct answer: Understand the problem

The governing concept is the personal and responsive nature of human teaching. When a teacher listens carefully to a child, the teacher can notice confusion, identify the child’s difficulty, and adapt the explanation or support accordingly. Thus, option B is correct: a human teacher can understand the child’s problem by listening. This ability depends on communication and empathy, which are central to the importance of human teachers in “The Fun They Had.” Option A is unrelated to listening, while options C and D describe mechanical or accidental actions rather than a useful educational response.
