Which of these Australian Aboriginal populations would have suffered the LARGEST number of deaths in the 1780s and 1790s?
A) settlements in the Outback
B) roaming bands of hunter-gatherers
C) densely populated coastal settlements
D) villages along Australia's west coast

C: Densely populated coastal settlements would have suffered the largest number of deaths.

Explanation:

After the Europeans started to settle in Australia, the Aborigines suffered multiple heavy hits. They were seen as primitive and useless, without value as people.

Europeans originally settled on the coast, where many Aborginals lived. They were carelessly murdered. Also, the diseases brought by the Europeans decimated the numbers of the Aborigines that were in contact with them, and very quickly their numbers went so low that they were on the verge of going extinct as people.

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 % " .

the answer is   b. coronado.
