Several critics have claimed that any contemporary poet who writes formal poetry -- poetry that is rhymed and metered -- is performing a politically conservative act. This is plainly false. Consider Molly Peacock and Marilyn Hacker, two contemporary poets whose poetry is almost exclusively formal and yet who are themselves politically progressive feminists. The conclusion drawn above follows logically if which one of the following is assumed? ['No one who is politically progressive is capable of performing a politically conservative act.', 'Anyone who sometimes writes poetry that is not politically conservative never writes poetry that is politically conservative.', "The content of a poet's work, not the work's form, is the most decisive factor in determining what political consequences, if any, the work will have.", 'No poet who writes unrhymed or unmetered poetry is politically conservative.']
