When Ramone spoke about the need for regular health check-ups, he was so knowledgeable, so trustworthy, and so energetic in his delivery that everyone responded quite positively to his speech. What aspect of a good persuasive delivery did Ramone demonstrate?

Ramone demonstrate, Ethos aspect of a good persuasive delivery.

Explanation:

Unlike other aspects of persuasive delivery like the Logos and pathos, ethos describes the credibility of the speaker based on his performance as seen by his audience. Ramone had made known to them his quality of being believable or trustworthy about his information possible from what he told them about his experience with a regular check-up.

He must have told them of another person's experience, possibly the person did not do regular check-ups for his STI although he had visited the bar and clubs frequently, got drunk and sometimes used prostitutes, he didn't care about check-ups that much and when his wife finally got to force him to check, he realized that he had contracted from one person there and had passed in onto his wife, and eventually he died. His audience must have seen the importance of regular check ups.
