How did the Jim Crow laws support the Bourbon agenda?

They returned Louisiana to the pre-Civil War conditions of white superiority over blacks throughout society.

They improved social relations by creating very limited segregation.

They made blacks and whites require separate laws even though they were equal.

They created racial equality by demanding that segregation be equal in status and condition.

Explanation:

The Jim Crows laws were a legal way to circumvent the 14th Amendment and othe federal legislation giving African Americans equality passed after the end of the Civil War. Those laws, passed by state legislatures in several southern states,  simply provided legal tools or methods to impede the black people to vote in elections, one of the basic citizen rights.

In Louisiana, there were segregated schools, black and whites could not buy products in the same store, interracial marriage was forbidden.
