Question

1. what action did congress take to support southern african americans?○ congress overturned johnsons vetoes on major reconstruction legislation.○ congress refused to pass the ten percent plan.○ the senate failed to pass the civil rights act of 1866.○ radical republicans promoted the black codes.

Explanation:

During Reconstruction, President Andrew Johnson vetoed key bills meant to protect and support Southern African Americans. Congress, led by Radical Republicans, overrode these vetoes (e.g., the Civil Rights Act of 1866) to enact laws that safeguarded Black rights, which directly supported Southern African Americans. The other options are incorrect: the Ten Percent Plan was Lincoln's, the Senate passed the 1866 Civil Rights Act after overriding Johnson's veto, and Radical Republicans opposed black codes.

Answer:

A. Congress overturned Johnson's vetoes on major Reconstruction legislation.
