. What is meant by “people disappeared”? Why do you think
most black people did not choose to speak out against
segregation in Mississippi?

They were frightened

Explanation:

At that point, there were many laws and racist groups who would oppress people of colour and those who supported equal rights (some were even violent).

This meant many people were scared to stand up in case they were also discriminated against or harmed.

Hope that helped :)

it was on the rise and doing very well and would continue to do well until the great depression from 1929-1939
