Spoiler : PP3 ETS VERBAL SECTION 2 Q NO 18

Why is the answer E?

Is option D incorrect because social realists did not depict “the past” in harsh terms. Rather, they depicted “the present” in harsh terms. Is my understanding correct here?

I know why all other options are incorrect but I cannot figure out why is the answer E? and what is exactly wrong with Option D in this question?

Thanks
