The correct answer is:
c. Douglass uses a righteous tone to speak from the point of view of an enslaved person, while Lincoln employs a neutral tone to speak about slavery from a detached perspective.
Frederick Douglass’s passage conveys a strong sense of moral outrage and righteousness concerning the injustices faced by enslaved individuals, reflecting the perspective of someone who has experienced the suffering of slavery. In contrast, Abraham Lincoln's passage adopts a more neutral, analytical tone that discusses the causes of the Civil War and the political context surrounding slavery without the same level of emotional intensity.
