Which of the following improves the credibility of a persuasive argument?

The use of reputable sources significantly enhances the credibility of a persuasive argument because it provides a foundation of trustworthiness and reliability. When an argument is supported by evidence from well-respected studies, experts, or established organizations, it demonstrates that the claims made are backed by valid research or authoritative opinions. This not only helps to validate the argument but also persuades the audience to accept the viewpoint being presented, as they are more likely to rely on information that comes from credible sources.

In contrast, muddled explanations can confuse the audience and weaken the argument, making it harder to follow and less convincing. Broad generalizations without evidence can lead to skepticism, as the audience may feel that a claim is unfounded and not worthy of their trust. Similarly, presenting only one side of the argument can create a biased perspective, which undermines the overall effectiveness and perceived fairness of the discourse. In persuasive communication, credibility is essential, and reputable sources play a crucial role in establishing that credibility.
