Question

why did some white people want to take power from african american voters?
african americans threatened to break away from south carolina and form their own state within the sea islands and along the coast, which would hurt the state’s economy.
many white people felt threatened by the number and power of african americans in south carolina and wanted to return to the way things were in the past.
african americans refused to vote and participate in any state or federal election run by former confederate officers.
african americans promised that, when they gained power, they would punish former enslavers as well as members of the confederate army.

Explanation:

After the Civil War, African Americans gained voting rights and political influence in South Carolina. White supremacist groups and many white residents feared this shift in power, as it challenged the pre-war racial hierarchy and their dominant status. They sought to disenfranchise African American voters to revert to the previous system where white people held exclusive political control. The other options are not historically accurate: there was no widespread threat of African Americans forming a separate coastal state, African Americans actively participated in elections when allowed, and there was no mass promise to punish former Confederates as a primary driver of white voter suppression.

Answer:

B. Many white people felt threatened by the number and power of African Americans in South Carolina and wanted to return to the way things were in the past.
