Explanation:

The Indus Valley civilization was spread around the Indus Valley. It was a highly advanced civilization for its time, having numerous achievements. The people lived good, and it was a peaceful civilization, leaving not a single trace of war behind it. There was no strong, central government though, but each city was governing itself, while having close ties and good relations with the other cities. The reasons for the collapse of this civilization are still not totally clear, but it corresponds with the migration of the Aryan people (whites), and considering that the Aryans were much more aggressive and military well prepared, they wouldn't have had any problem in overtaking these lands. It seems though that it was more of a peaceful migration and gradual integration and mixing of the two people groups.

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 % " .
