I want to know the answer to the following question:
Which character has some critics deemed a variation of a contented slave?
All the background I'm provided with is that "In its use of racial epithets, stereotyped depictions of superstitious blacks, and Calpurnia, who to some critics is an updated version of the "contented slave" motif and to others simply unexplored, the book is viewed as marginalizing black characters.". Is that enough to answer the question?
