Question

1. how did the scalawags change government in the south?○ they administered loyalty oaths to former confederates.○ they created the public school system.○ they brought republican ideas to southern politics.○ they used legislation to stop african americans from voting.

Explanation:

Scalawags were white Southerners who supported Reconstruction and the Republican Party during the post-Civil War era. They helped introduce Republican policies (focused on Union loyalty, civil rights progress, and modernizing the South) into Southern state governments, opposing the former Confederate elite's hold on power. The other options are incorrect: loyalty oaths were imposed on Confederates by federal/Republican authorities, public school systems were a broader Reconstruction effort not solely by scalawags, and legislation to block Black voting was pushed by white supremacists opposing Reconstruction, not scalawags.

Answer:

They brought Republican ideas to southern politics.
