Question

Quizplus · Accepted Answer

Effective speakers use a variety of supporting materials such as statistics, examples, anecdotes, and expert opinions to justify each main idea in their speeches. This helps establish credibility and persuade the audience towards their point of view. A sworn statement of validity is not necessary as the supporting materials itself should provide evidence to support the claims. Using only one primary source can be limiting and may not provide a comprehensive view on the topic. Skillful nonverbal delivery strategies can enhance the presentation, but they do not necessarily justify the main ideas.
