1. To what extent, if any, had the intensity of white supremacy changed by the 1920s from what it had been two to three decades earlier?

The correct answer to this open question is the following.

Although there are no options, we can say the following.

After their former years during the Reconstruction Era, the supremacist group called the Ku Klux Klan had a resurgence time in the United States after World War 1. Yes, we are talking about the 1920s, a time of changes in America.

The intensity of the resurgence? Well, it was the same, if not more. It seemed like a revival to the supremacist group in that the number of members increased dramatically up to 100,000 in the United States. This worried African Americans and other minorities because the numbers no just increased in the southern states but in the Northeast and the Midwest. They also violently attack Jews, Catholics, and Latino people.

hey i did something like that before, what is the quesiton?

the correct answer is:   "   3.6 % " .

          →   the unemployment rate is:   " 3.6 % " .

explanation:

to calculate the "unemployment rate" :

the "unemployment rate"   =

  [# of people unemployed] /   [working age population]   * 100 %   ;

                =   [9 million] / [250 million]     *   100 % ;

    →     note:   the units of "million" cancel out;

                    since:   " {million} / {million} = 1 " ;

                =   (9 / 250)   * 100 %   ;

                = 0.036 * 100 % ;

                =   3.6 %

answer:   the unemployment rate is:   " 3.6 % " .
