Answer
$$III\ \ region$$
Work Step by Step
we have this information
$U=\left\{\begin{array}{l}
{\text { Elementary school teachers, police officer, surgeion, }} \\
{\text {Airline Pilot, Banker, Family doctor, Lawyer }}
\end{array} \right.$
$A=$ The set of jobs for which more than 20$\%$ prefer men.
$\ \ \ =\{\text { Police officer, surgeon, Airline Pilot, Family doctor, lawyer }\}$
$B=$ The set of jobs for which more than 20$\%$ prefer women,
$\ \ \ =\{\text { Elementary school teacher, Banker, Family doctor }\}$
$A \cap B=$ The common jobs which more than 20$\%$ prefer men and women
$\quad\quad\quad=\{\text { Family doctor }\}$
So we can see that $\text{(banker)}$ is a job that belongs in $B$ but not in $A$;
therefore, it belongs in the $III$ region.
