Sex (m) (f)
The fact that there are no other choices, letters, numbers, symbols, helicopters, or kabuki-dances is VERY refreshing, and begins to give hope for humanity in the future. (see what I did there?)
I didn't pay much attention to that, however now that you mention it, I'm guessing there is a good chance that is not actually a current survey, but rather is something somebody copied from several years back.
I seriously doubt any University except maybe BYU does not have non-binary as a choice when asking for gender.
Having only M & F as the choices would get the faculty in trouble crazy quick.
