Which of these people is most likely to earn a low wage job?

Without a list to select from you could make the following assumptions:

1. An uneducated person with little or no formal education; possibly even illiterate.
2. That (generally speaking) the person would be a woman.

While point 2 above sounds sexist or discriminatory, it is a fact in many third world countries that women are not afforded the same levels of education and entitlement. In some societies they are not allowed to study past elementary school level and are then encouraged to work in menial potions until they are married.
