Why Have Feminist Social Scientists Been More Successful in Offering

Why have feminist social scientists been more successful in offering single studies of particular groups than in providing systematic comparisons within the same society?

A) It is not important to compare families of different racial identities within the same society.
B) Racial and class differences are often treated as a unique variation on the white, middle-class "norm," as opposed to being understood as the product of ubiquitous social forces.
C) Single studies of particular groups of families and women are more illuminating because they highlight the special structure of racial and ethnic groups.
D) Feminist social sciences have not offered any insights on the impacts of race and class.
