The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The similarity between Dixiecrats and the Civil Rights Act of 1957 was that the Dixicrats severely opposed the Civil Rights legislation proposed by President Dwight Eisenhower and Democrats in Congress weakened the act.
The Disxicrats from the South always opposed giving rights to African Americans and wanted to maintain the Jim Crow laws and black codes that started after teh Reconstruction period in the southern states.
The Civil Rights Act of 1957 included the creation of a Civil Rights Commission that had the power to investigate racial segregation practices. But as I said above, Democrats in Congress questioned and weakened the final act.
The textbook’s authors are correct to conclude that Congress only has few, if there is any, powers remaining. Congress hasn’t declared war since 1941 of December, clearly presenting that Congress has no control over whether United States can go to war. One major reason that Congress is in this situation is because the president claims that that he inherent the sole executive power to defend America’s interest. Another major reason for Congress lack of war power is because of Truman.
The answer should be "Dissatisfaction with Athens's growing empire"
Hope this helped
