How does a human teacher give a child a chance to participate in a lesson?

Correct answer: By asking questions

The governing concept is active participation in learning. A human teacher can ask a child questions, listen to the response, clarify confusion, and then build the next part of the lesson around the learner’s understanding. This creates a two-way classroom instead of a one-way flow of information. Hence option A is correct. Sending the child home removes the child from the lesson, hiding a machine does not create meaningful participation, and stopping every answer prevents interaction. Questions are important because they invite thought, speech, and feedback. In the context of The Fun They Had, this is one reason a traditional classroom seems attractive: children could respond to a teacher and take part in a shared lesson rather than study alone with a teaching machine.
