I would research on the "wiring" of the brain between male and female. Females are said to use twice as many words in one day as males, while arguing the same topic. Male brains are wired to be concise, accurate, straight to the point in many cases. This would argue their success in construction, science, and math fields. Females can be more expressive, using descriptive language and explaining situations in greater detail to make a point, attributing their abilities in writing and even parenting. Good luck!
