AAMC FL 2 P/S terms (spoilers)

Does anyone have explanations for the following terms? They seem mostly self-explanatory but google didn't yield anything super clear.

-generational status
-social solidarity
-welfare state
-intersectionality of medicine
-difference between "randomized trials" and "experimental trials"

Thanks!
