An instructor by asking well-directed questions can make the difference between a dull lecture and a lively discussion.

• A. Not at all
• B. Sometimes
• C. False
• D. True

Answer: (D)

Purposeful questioning taps students' thinking, keeps them mentally engaged, and guides the discussion toward the lesson objectives. When questions are well directed—clear, open-ended, and tied to the key ideas—students articulate reasoning, connect concepts to real-world situations, and hear diverse perspectives. That active participation shifts a lecture from a one-way talk to a collaborative exploration, making the session more dynamic and memorable. So the statement is true: well-directed questions can make the difference between a dull lecture and a lively discussion. Saying it has no effect or that it only sometimes works misses the impact of well-designed questions, which consistently steer engagement and understanding.
