What challenges does slavery face after the American Revolution? In what ways do slaves and free blacks still face issues?

I don't have an answer to the first part but slaves and free black people still faced oppression because many whites still didn't treat black people equally and were very racist towards them. There were bathrooms, schools and water fountains only to be used by white people too.

the correct option is: a liberal.

the kind of person that is most likely to hold a left-wing political ideology is liberal because they have in common that they support human individual rights and liberties. also, they both have politically and economically centrist.

moreover, a liberal believes that everyone should have equal rights as well as opportunities to succeed in life, and the freedom to make their own decisions as long as they don't attack the rights of other people. all people deserve the same opportunities and basic needs.
