Answer:
D. Cugoano has a much more authoritative tone than Sancho, who is respectful to Sterne.
Step-by-step explanation:
In these lines, we learn that both authors are asking for a similar thing. Both Cugoano and Sancho are arguing that the black slaves need to be treated differently, and better. They both refer to the end of slavery. However, Cugoano employs a much more authoritative tone, as he wants to convey the idea that slavery is morally wrong. On the other hand, Sancho is more respectful to the audience, and his measures are presented as requests, rather than commandments.
