In this question I am confused why 'had existed' is incorrect. The question refers to 'great ice sheets had existed in now currently temperate areas'. Why is 'had existed' incorrect. Since the ice sheets existed before the area were temperate dont we have to use 'had existed' as opposed to 'existed'? Existed is the correct answer by the way.
