Answer: C. The words hideous, revolting, and false most affect the tone and meaning of this passage, so as to show the speaker's disgust over slavery.
Step-by-step explanation:
Frederick Douglass (1818-1895) was an American social reformer, orator, abolitionist and writer. Having himself escaped from slavery in Maryland, he became a leader of the abolitionist movement in Massachusetts and New York, famous for his oratory and antislavery writings.
On July 4th, 1852, he delivered a speech at the commemoration of signing of the Declaration of Independence. In the speech, he addressed the issue of slavery, and the injustice the slaves were subjected to. The use of words hideous, revolting and false, demonstrates his disgust over slavery.
