What is a "demonstration" in the context of cosmetology education?

In the context of cosmetology education, a "demonstration" refers specifically to a practical presentation where techniques and skills are shown and taught in real time. This typically involves an instructor or a trained professional showcasing how specific procedures are performed, allowing students to see the application of theoretical knowledge in a hands-on environment.

The correct answer highlights the duration of the demonstration, which is generally understood to be a presentation that is concise enough to fit within a typical educational framework. Demonstrations usually serve to illustrate techniques, products, or procedures rather than being extensive discussions or theoretical lessons.

The other selections might seem related to aspects of training and education, but they do not capture the essence of what a demonstration constitutes within this setting. Theoretical discussions lack the practical application, hands-on workshops generally involve longer training sessions beyond brief demonstrations, and self-study courses are typically independent of direct interaction, further diverging from the interactive nature of a demonstration.
