In the history of communication, we can see a transformation of a "hearing public, to a "reading public," to an "interacting
public." What forces converged to precipitate these
transformations, and what benefits and challenges did they
produce. Reference specific historical events, individuals and
technologies in your answer.

a. "how old man winter was driven back” and “ormuzd and arimanes"

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 % " .
