Jim crow laws were forced upon minorities at the end of reconstruction by what means? the desegregation of all public facilities making it almost impossible for them to vote segregating blacks from whites in most states the repeal of the fourteenth amendment

The best answers are:
-making it almost impossible for them to vote
-segregating blacks from whites in most states

Jim Crow laws sought to scale back the rights and equality that African Americans were receiving in the Reconstruction Era following the Civil War. To this end, Jim Crow states in the South made it virtually impossible for blacks to vote, and often tampered with black votes. 
They also made segregation a formal written law in the Southern states, outlawing the shared use of almost all facilities, public or private, by black and white people. 

Jim Crow could not, however, repeal the 14th Amendment and did the opposite of desegregating public facilities.
