A public speaker who carefully verifies the persuasive facts they plan to present to their audience is demonstrating the ethical dimension of public speaking.

Explanation:

A public speaker must be concerned with the ethical dimension of public speaking throughout the process of writing and giving a speech. Speakers must be honest, avoiding lies and plagiarism at all costs. They also must worry about their goals, what they wish to accomplish with that speech.

A speaker verifying the persuasive facts they plan to present is an ethical action. They do not wish to be dishonest, presenting support information that is incorrect or even nonexistent. Imagine how they audience would feel when they realized the "facts" were misleading or made-up. The speaker would lose all credibility, his/her image would be tainted with mistrust.
