The act of showing how to perform a task to others.

• A. Understanding
• B. Interference
• C. Preparedness
• D. Demonstrating

Answer: (D)

Demonstrating is the act of showing how to perform a task to others. It involves presenting the exact steps, movements, and safety considerations so learners can observe the correct method and replicate it themselves. This makes the procedure tangible and easier to internalize, especially in hands-on skills common in fire training, such as handling equipment or applying a technique in real situations. Understanding, while essential, refers to mental grasp and may not involve seeing the action performed; preparedness is about readiness to act, not the act of teaching; interference is anything that blocks learning. A well-done demonstration provides a clear model, highlights critical cues, and often sets the stage for guided practice and feedback.
