7. Evaluate Considering the author's purpose and audience, which
Burka [1]

The persuasive techniques that must take into account the author's objective and audience are the rhetorical resources ethos, pathos, and logos.

<h3>What are ethos, pathos, and logos?</h3>
  • They are rhetorical resources.
  • They are powerful persuasive elements.
  • The ethos is persuasive through ethics.
  • Pathos is persuasive through sentimentalism.
  • Logos is persuasive through logic.

The elements used by pathos, logos, and ethos must be aligned with the author's objectives, so that the author can manipulate the words used and the persuasive sentences according to these elements, proving a specific response from the public.

These rhetorical resources must also be aligned with the nature of the audience, as a more emotional audience may not be affected by a discourse based on ethos or logos, for example.
