Before the Age of Exploration, most Western Europeans only knew about the European continent. Travel and trade were difficult and dangerous before the Age of Exploration. Few maps existed and few people could read or write. However, with the Age of Exploration, Western Europeans began to explore "new" lands. Western Europeans began to seek adventure and travel.

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 % " .
