PLEASE HELP! IM FAILING THIS CLASS!! What would be an example of De Facto Segregation?

Racially focused neighborhoods forming during urbanization

Civil Rights Act of 1964

Plessy vs. Ferguson "Separate, but equal"

Racially focused neighborhoods forming during urbanization.

Explanation:

De Facto Segregation was a term used in the 60's that meant schools would not publicly segregate students, but in reality, school segregation continued.

The Civil Rights Act of 1964 prohibited racial discrimination in public places.

This would not be an example of De Facto Segregation.

The Plessy vs. Ferguson "Separate, but equal" case kept racial segregation constitutional, because it was "fair" in their eyes.

An example of separate but equal is: Black people and White people had to drink from separate drinking fountains, but it was "fair" because both of them technically had drinking fountains.

This is not an example of De Facto Segregation because this is public segregation made "fair".

Racially focused neighborhoods formed during urbanization caused schools to become racially separated. It happened because white people would all go to one rich school in district, and black people who lived in another neighborhood would go to another school.

This is a an example of De Facto Segregation because it caused the schools to become separate without the direct use of segregation.

what are the options?
