Answer: (D) They moved from the North to the South and helped Republicans get more voters.
Step-by-step explanation:
Carpetbaggers were Northerners who moved to the South during Reconstruction (1865-1877) after the Civil War. They influenced the social structure of the South by supporting the Republican Party and its policies, which aimed to break down pre-war racial hierarchies and promote civil rights for African Americans. By expanding the Republican voter base and promoting policies that benefited newly freed African Americans, they helped reshape the political and social landscape of the South. However, their presence also fueled resentment among many white Southerners who viewed them as opportunistic outsiders.
