Took the GRE. Now what to study?

[Deep13]

680 verbal, 550 quantities. I'm going back to school for my masters in history in order to teach undergraduates. I have to decide what area to study. Whatever I choose comes with a foreign language requirement.

There are three main contenders: Latin American (Spanish & Portuguese), Middle East (Arabic and maybe Turkish) or China (Mandarin). The language requirement is for reading, not necessarily speaking or hearing. Middle East seems to be a field that's in demand since it is present day conflicts that create a demand among undergraduate students. I hear mixed things about Chinese. On the one hand I hear China's rising dominance in the world gives it increasing demand. OTOH, I hear that most schools are pretty limited in their Chinese departments and that there isn't much demand. Latin American was in demand in the 1960s and 70s but has been waning since then. OTOH the rise if Latino/as in this country may mean an increased demand in the future as more and more Latins in this country enroll in college. Unfortunately, there doesn't seem to be much effort by schools to attract Latin American students.

My own personal interest is more ancient and medieval which favors Middle Eastern and maybe China to a lesser degree.

I'm just thinking out loud. Obviously, I have to decide for myself.
