The United States refused to support popular elections in Vietnam in 1956 because they
O A. feared that the Soviet Union would take over if the elections went
against the Communists.
OB. had promised to give Vietnam back to the French.
O c. had promised South Korea that its elections would be held first.
O D. feared that Vietnam would vote for a Communist government.

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 % " .
