Which is a form of support used to explain ideas to the audience?

• A. Definitions
• B. Examples
• C. Testimony
• D. Statistics

Answer: (A)

Definitions provide a precise meaning for terms, establishing a shared starting point so the audience understands the idea without ambiguity. When you define a term clearly, you remove confusion and set a solid foundation for whatever follows, whether you’re describing a concept, process, or condition. This makes subsequent explanations more effective because the audience isn’t guessing what key words mean. Other supports like examples, testimony, or statistics are useful for illustrating or backing up points, but they rely on knowing what the terms themselves mean. In health communication, a clear definition ensures everyone is “speaking the same language” as you unfold the idea.
