Answer:
1- The correct answer is C. Some white Southerners joined the Klu Klux Klan because it was a powerful way to oppose the North.
2- The correct answer is A. The Klu Klux Klan targeted the Freedmen's Bureau because its members did not believe African Americans should be educated.
3- The correct answer is A. Many white Southerners were opposed to the Reconstruction because they felt Northerners were getting rich at their expense.
Step-by-step explanation:
1- The Klu Klux Klan was dedicated to oppress the "carpetbaggers" (northern inhabitants who had moved to the south), the "scalawags" (Southern Republicans), and the newly freed slaves. The conservative and supportive past of the Democratic Party made many of its members want to belong to the KKK, in order to oppose the Republican policies that came from the North.
2- The Ku Klux Klan sought political and social control of freed slaves. In particular, it attempted to undermine education, economic advancement, the right to bear arms and the electoral rights of African-Americans.
3- Thousands of Northerners arrived to the south as missionaries, teachers, businessmen and politicians. The hostile whites began to refer to these politicians as "carpetbaggers", accusing them of reaching the south only to make use of their power as part of the victors in the Civil War, in order to obtain economic deals at the expense of the Southern population.
