Question

what were some obstacles in implementing the brown v. board of education decision?
the supreme courts hesitance to deliver a strong ruling
the lack of support from african american communities
the resistance of many white americans against integration

Explanation:

The Brown v. Board of Education ruling required school desegregation, but many white Americans in regions with segregated systems resisted this change through actions like school closures, boycotts, and legal delays. The Supreme Court issued a clear, strong ruling (so the first option is incorrect), and African American communities widely supported the decision to end segregation (so the second option is incorrect).

Answer:

the resistance of many white Americans against integration
