Laws are passed to regulate the funding of political campaigns in an effort to ensure that only a handful of candidates run for office.
all candidates who run for office have equal funding.
corporations and the wealthy cannot donate an excessive amount.
candidates focus on the day’s controversial issues

C) corporations and the wealthy cannot donate an excessive amount.

Unfortunately there are loopholes that allow things like super PACs to form, but ideally such laws are aimed to prevent very wealthy people/corporations from exercising too much heavy influence on elections and politics in general. This would then lead to a more fair balanced playing field.

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 % " .
