Question 1: Many Americans were concerned about the growth of the Ku Klux Klan. How does Document A provide evidence of this?

We are told that they estimate nearly 2/3rds to 3/4ths of all the white men between 16 and 50 are members of the ku klux clan which emphasizes just how many members there already are because their are a lot if caucasien (white) men between the ages of 16 and 59

Around 2-3/4th of white men aged 18-50 in 1870’s were part of the KKK, assuming there was 100,000 white men, around 60,000 would be in the kkk, just showing the sheer mass of the group at the time
