(1) Your answer is very clear and good. However, I don’t agree with the part of your answer “Grosz offers a kind of veiled (not open) call to feminists”. I think Grosz offers an open call to feminists in her article with many reflections on Darwin’s theory.
(2) You summarized key points very well, but it is better to use your own words and add your own idea.
(3) I agree with your idea. Subordinated groups not only follow domination groups but have possibility to change the power balance between two groups and also for the transformation.
