A. putting in local parks to provide a break from city life

Explanation:

Considering the available options, in the early 1900s, the urban planners decided it was a good change for a city to "put in local parks to provide a break from city life."

This is because, during the early 1900s, the United States of American cities are beginning to be congested and more industrial and commercial than ever before. People often don't have much going for them other than work-related activities.

Hence, the urban planners felt that it will be a good change to have local parks where people can have fun and appreciate natural environments, to provide a form of break from city life

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 % " .
