Answer:
They suggest extreme hunger.
Step-by-step explanation:
"Narrative of the Life of Frederick Douglass" is a memoir by a former slave Frederick Douglass. In it, he recounts how he had slaved in plantations before he eventually got education and his freedom.
Douglass used the words "mangled" and "emaciated" in chapter VI while talking about Mary, the Hamiltons' slave. Douglass was talking of how different slaves were treated in cities and plantations. But, there are also instances like the Hamiltons who treats their slaves with utmost prejudice and violence. The slaves Henrietta and Mary were starved and made to do extreme work, along with constant whippings. Douglass uses the words "mangled" and "emaciated" to emphasize on the extreme hunger that Mary and Henrietta had to endure in the Hamiltons' home.
