Stevie reads that womens and mens brains are organized differently, and therefore concludes that this organization produces sex differences in behavior. What is wrong about Stevies logic?
a)  A brain difference does not necessarily produce a behavioral difference; different brain organizations can produce the same behavioral outcomes.
b)  Relatively small differences in brain organizationa few hundred neural connections or soare sufficient to impact behavior; overall organization is beside the point.
c)  All brain differences are caused by sex stereotypes.
d)  Sex differences in behavior are actually due to sex differences in brain development rather than sex differences in brain organization.
