This week I am doing a series of ad-hoc tests in my classes. It's not a formal assessment as my course has no formal assessment but I am getting the students to work in groups where each group has a pair of opposed sentences to discuss. For example "Chinese traditional medicine is better than western medicine" and "Western medicine is better than Chinese traditional medicine."
One such pair is "There are some jobs that only a man or only a woman can do" and "Men and women can do any jobs equally well."

Groups discussing this usually go for the latter. One student went for the former so I asked him which jobs he had in mind. While he didn't have the word, he described the concept succinctly enough and I didn't have an answer. He was right, wet nurse is a job that only a woman can do.

Yep, that is correct.

Besides that, it's pretty equal.
