32) D

A – Wrong
We cannot confirm what are the exact values of wages. We are only given proportions of wages relative to the wages obtained by 15 year olds for each sex.

B – Wrong
Again, we do not know the exact wages.

C – Wrong
Not necessarily.
e.g. Wage proportion of women in education after 21 shows a downward trend.

D – Correct
The downward trend in the graph suggest this.

E – Wrong
We only have proportions of wages compared with the wages of 15 year olds. We are not given information about wages relative to people leaving education at 18.
