Answer:
The incorrect answer is B.) Jim Crow Laws were passed to segregate poor white Americans in the south as well
Explanation:
Everything else is true, heres how:
A.) Jim Crow Laws contributed to racism and violence against African Americans.. "Jim Crow Laws were a collection of state and local statutes that legalized racial segregation.....those who attempted to defy Jim Crow laws often faced arrest, fines, jail sentences, violence, and death. " quoted from https://history.com/topics/early-20th-century-us/Jim-crow-laws
C.) Jim Crow Laws made segregation the law in the south
"Jim Crow Laws soon spread around the Country (talking about the united states) with even more force than previously. Public parks were forbidden for African Americans to enter, and theaters and restaurants were segregated" quoted from https://history.com/topics/early-20th-century-us/Jim-crow-laws
D.) Jim Crow Laws lasted until the civil rights movement in the 1960's "Jim Crow laws were a collection of state and local statutes that legalized racial segregation.Named after a Black minstrel show character, the laws --- which existed for about 100 years, from the post- Civil War era until about 1968--" quoted from https://history.com/topics/early-20th-century-us/Jim-crow-laws
Now all over this sight and others it only says "racial segregation" NOT anything about segregation among whites happening.
