Name the two parties that preceded the Republican Party

Explanation:

The Whig party was the main precursor to the Republican party. They were very influential in the U.S. before the Civil War and if not for sectional divisions, would have contributed a slew of Presidents. The Whig party wasn't a big opponent of slavery but the Northern Whigs felt strongly enough against it to switch to the Republican party in the decade before the Civil War.

There was also the Free Soil party. This party was dedicated to ensuring that slavery would not spread to the new territories that the U.S. had acquired. They found it beneficial to join the Republican party which was anti-slavery.

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 % " .
