01 A teacher notices confusion on a student's face then slows down and points toward a diagram. What does this demonstrate?
Answer and explanation
Correct answer: A. Adaptation based on non-verbal feedback
Explanation: The governing concept is feedback in non-verbal communication. The student’s confused facial expression gives the teacher information about understanding, and the teacher adapts by slowing the explanation and using a pointing gesture. Thus option A is correct. This is not ignoring the learner, leaving the topic, or using only visual communication, because spoken explanation and visual support are being combined responsively.
