The 5% that is counted against me was on the question, "Women should accept their bodies as they are. Women should not have to conform to wacky beauty ideals." I answered "not sure," because even setting aside health issues (women and men shouldn't accept unhealthy bodies if they can make them healthy) the fact is that men care about women's beauty, as best I can tell likely for biological reasons and not just social ones, and women ignore that at their peril.
Of course, by definition women shouldn't have to conform to wacky beauty ideals. And in a better world inhabited by people who are biologically and genetically different from humans women wouldn't have to conform to any beauty ideals.
In today's world, though, I don't think it's quite accurate to say that "Women should accept their bodies as they are." Some attempts to change one's body are likely counterproductive or on balance harmful. But others (whether dying graying hair, removing hair from certain places, using effective makeup under certain circumstances, mild dieting or exercise for esthetic reasons and not just health reasons, and so on) are probably wise ideas for many women who care about the things that many women understandably care about.
The quiz has some of the usual problems with such quizzes, for instance in the question "A woman should be able to marry and have kids with anyone she wants -- including another woman"; that's a measure of commitment to equal rights without regard to sexual orientation, which strikes me as pretty conceptually different from feminism. And of course calling this an "Are You a Feminist?" quiz deliberately obscures the fact that there are many different kinds of feminist. But as a measure of one's agreement with equity feminism, the quiz is probably fairly decent.
