Final answer:
Atticus's speech in 'To Kill a Mockingbird' was persuasive through its logical and moral appeals, despite not achieving an acquittal, revealing the entrenched racism of the time.
Step-by-step explanation:
In To Kill a Mockingbird, Atticus's speech was persuasive because he employed logical arguments, appealed to the jurors' sense of justice, and highlighted the lack of evidence against his client, Tom Robinson. Additionally, he tapped into moral reasoning, implying that the jury should not be swayed by racial prejudice but should instead focus on the truth of the matter. His speech, however, may not have been entirely persuasive to the prejudiced jury of that time and place, as it did not result in an acquittal, highlighting the deep-seated racism that could not be overcome by logical arguments alone.
