A study of the difference in earnings between men
and women in the country of Naota found that the
average annual earnings of women who are employed
full time is 80 percent of the average annual earnings
of men who are employed full time. However, other
research consistently shows that, in Naota, the
average annual earnings of all employed women is 65
percent of the average annual earnings of all
employed men.
Which one of the following, if also established by
research, most helps explain the apparent discrepancy
between the research results described above?
(A) In Naota, the difference between the average
annual earnings of all female workers and the
average annual earnings of all male workers
has been gradually increasing over the past 30
years.
(B) In Naota, the average annual earnings of
women who work full time in exactly the
same occupations and under exactly the same
conditions as men is almost the same as the
men’s average annual earnings.
(C) In Naota, a growing proportion of female
workers hold full-time managerial,
supervisory, or professional positions, and
such positions typically pay more than other
types of positions pay.
(D) In Naota, a larger proportion of female
workers than male workers are part-time
workers, and part-time workers typically earn
less than full-time workers earn.
(E) In ten other countries where the proportion of
women in the work force is similar to that of
Naota, the average annual earnings of women
who work full time ranges from a low of 50
percent to a high of 90 percent of the average
annual earnings of men who work full time.
