Answer 1

The most convincing aspect of a speaker's argument is using relevant and sufficient evidence. While including many opinions, providing a call to action, and researching the topic thoroughly can all enhance an argument, the foundation of a persuasive argument is built on solid evidence that supports the claims being made. Relevant and sufficient evidence helps to establish credibility and makes the argument more compelling to the audience.
