Although Antietam was a setback to
Lee's plans, the Union failed to take
advantage of the situation. Lincoln
replaced McClellan, but his new
generals lost decisively at
Fredericksburg, Virginia (December
13, 1862), and Chancellorsville,
Virginia (April 30 - May 4, 1863).
Which two words would BEST replace "setback"
and "decisively" in the selection above?

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 % " .
