Because males are only slightly higher than females,there should be considerable overlap in scores,meaning that answers a and b are false.Answer c is false because boys are higher than girls in Trait A,meaning that their scores start higher and end higher,which means answer d is true - there should be considerably more boys with very high levels of Trait A (those at the extreme end of the distribution).
