Answer:
- Use impassioned language and an enraged tone
Explanation:
Ethos is elucidated as one of the three persuasive appeals(as stated by Aristotle), the other two being logos(logical appeal) and pathos(emotional appeal). It primarily aims to persuade the readers ethically through the credibility or character of the speaker.
As per the question, the 'use or impassioned language and an enraged tone' will go contradictory to establish the ethos in a claim or proposal instead it would ruin the speaker's character and credibility among the audience by leaving a negative impact on the audience's mind through his fervent and infuriated tone which would present the author's approach as unethical and antagonizing.
