How does a human teacher increase children's participation in class?

Correct answer: By giving opportunities for questions, discussion, and activity

The governing concept is active and interactive learning. A human teacher can invite questions, organise discussion, ask different learners to explain their ideas, and use activities that require cooperation or practice. These methods give children a meaningful role instead of making them silent receivers of information. Therefore option B is correct: participation grows when students are allowed to ask, speak, investigate, and act. Option A creates isolation, while option C merely describes the use of a screen and does not ensure involvement. Option D removes explanation and guidance, making learning more difficult. In the context of the story, a human classroom is attractive because children can learn together and respond to one another, unlike Margie’s solitary mechanical lessons.
