Answer:
Ethos
Explanation:
Ethos is a Greek word that means, "character".
Ethos is a rhetorical device that tends to appeal to the speaker's or writer's credibility or character.
Ethos gives the audience the impression that the writer or speaker possesses greater experience or knowledge and should, therefore, be believed.
Here, Harriet Tubman does the same thing. She elaborates her experiences to the runaways and tries to convince them through an appeal to credibility.
