The names given to positions of power and authority, like "chairman" and "policeman," often emphasize the male gender. Why does this matter?
a. The names imply that one gender is more suited for a particular job than the other.
b. It doesn't really matter what words are used to describe a position.
c. The names help deter men from entering into incompatible fields.
d. The names are confusing, because more and more women are entering these professions.
