The act of showing how to do something or how something operates is a:

• A. discussion
• B. demonstration
• C. practical skill evolution
• D. presentation

Answer: (B)

Showing how to do something or how something operates is demonstration. A demonstration involves performing or visually presenting the steps of a task or the operation of equipment so learners can observe the method in action, often with narration or guidance as the task unfolds. This direct, observable approach helps learners see the correct sequence, technique, and outcomes. A discussion is about exchanging ideas without necessarily showing the steps, and a presentation typically conveys information rather than guiding through the actual performance of a task. The term practical skill evolution isn’t a standard descriptor for this activity, so demonstration is the precise term.
