1/2

Explanation:

Europe suffered an especially significant death toll from the plague. Modern estimates range between roughly one-third and one-half of the total European population in the five-year period of 1347 to 1351 died, during which the most severely affected areas may have lost up to 80 percent of the population.

i thinl it is the 1st answer

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 % " .
