Answer
Males and females desire in equal proportion to become smart.
Work Step by Step
That males and females desiring in equal proportion is shown in the graph when the heights of the blue and green bar are equal to each other.
In the graph, there is one attribute in which the blue bar is as high as the green bar: the 'Smarter' one. ('None of these' is not an attribute)
Thus, males and females desire in equal proportion to become smart.
