How do you think a total war affected business and factory owners? Newspapers reporters? Children? Why do you think many women were granted the right to vote following World War I?

Explanation:

It’s no surprise we think the 1917 Bolshevik revolution was bad for Russia. Which other major economy suffered five massive declines in industrial or agricultural output in the 20th century? That’s the result of two prolonged invasions, a civil war, two famines plus the collapse of all trading links and an economic system.

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 % " .
