Step-by-step explanation:
The plantation where Sethe and Paul D were slaves is known as "Sweet Home" in the novel "Beloved" by Toni Morrison. However, the provided information does not reveal the name of the plantation but describes the conditions and cruelty faced by slaves on various plantations during that time. Plantations like the one owned by Colonel Lloyd, who kept hundreds of slaves, or the brutal treatment of slaves by people like Mr. Thomas Hamilton, as well as the more strategic and business-like operation of the Great House Farm, are all part of the harrowing backdrop against which the story of "Beloved" is set.
