the answer for apex is The widespread resentment in Germany toward the treaty of Versailles.
Answer:
The Brown Vs. Board of Education accomplished getting rid of the "separate but equal" idea in schools.
Explanation:
The "separate but equal" idea was basically that even though blacks and white were separated they could be equal. But what happened was that the blacks got the everything worse than the whites. For instance, if water fountains were an example of this, the water fountain a white person drank out of was all nice and fancy. But right next to it would be the another fountain that was all gross and nasty that the African Americans had to drink out of. So in the end the people started coming to their senses and realized how wrong it was to have them separate and nothing was equal. This led to Brown vs. Board of Education to bring up this idea in schools and it helped later abolish this idea all together in so many other public places not just schools.
