Emancipation

Explanation:

The Southern states opposed emancipation. Emancipation refers to the liberation of all slaves. The South depended heavily on slaves due to their reliance on plantations. As plantations were massive, they required an enormous amount of cheap labor in order to become profitable. Therefore, slavery was vital for the economic success of the South.

explanation:

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 % " .
