Answer: All of these answers are correct.
Explanation:
Research has shown that public schools today are more racially segregated now than they were when the forced busing program was introduced in the 70s due to the Federal government not doing much to help in desegregation efforts.
This of course is after bussing had been found to increase integration which in turn improves the attitude of students in relation to race as well as improving the test scores of minorities.
White flight which is a phenomenon that sees white people flee to the suburbs where they would be mostly white people, made desegregation hard because the schools in those suburbs would be mostly made up of white kids.
As a result of opposition to forced bussing, the Supreme Court prohibited it unless it was done to circumvent deliberate segregation by the drawing of district lines that separated races.
