A city slave is almost a freeman, compared with a slave on the plantation. He is much better fed and clothed, and enjoys privileges altogether unknown to the slave on the plantation. There is a vestige of decency, a sense of shame, that does much to curb and check those outbreaks of atrocious cruelty so commonly enacted upon the plantation. He is a desperate slaveholder, who will shock the humanity of his nonslaveholding neighbors with the cries of his lacerated slave. Which phrase is evidence that enslaved people on plantations were treated especially badly?

“those outbreaks of atrocious cruelty so commonly enacted upon the plantation.”
“will shock the humanity of his nonslaveholding neighbors”
“He is much better fed and clothed”
“There is a vestige of decency, a sense of shame”
