Which of the following quotes provides support for douglass's main idea that slavery is dehumanizing?
a) "i had known what it was to be kindly treated."
b)"he [master] was a cruel man, hardened by a long life of slave holding." c)"the week before our intended start, i wrote several protections, one for each of us."
d)"the home plantation of colonel lloyd wore the appearance of a country village."

Well, to dehumanize means to treat someone as if they weren't human. So, from this we can already eliminate A and D because they have nothing to do with being treated badly. Now, if you look at C, it doesn't necessarily talk about being treated badly, but if you look at B, it says his master was cruel, which means his master treated him and others badly.

So, I would say the answer is B.

Hope this helps!
