What changes have taken place in the general public's attitude with regard to war as a result of the World War I experience?

Anti-war sentiments

Explanation:

World War 1 completely shattered everyone's expectations of what war was, with brutal trench warfare and terrible conditions throughout the entire war. War was seen as an adventure, and this sentiment remained until the American Civil War. People everywhere were horrified at World War 1, and books such as All Is Quiet On The Western Front were written about what soldiers had to endure daily.

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 % " .
