So what’s it’s saying is to write an Essay talking about how you might have read a story where this quotation has or hasn’t proved right. For example, I could say in the literature piece, “to kill a mocking bird”, the validity of many characters is shown when they face a highly controversial issue, racism, and how they act differently when they are out on the spot. So this would be an examples supporting that the quotation given to you IS true. And then you would just back it with pathos, logos, repetition , etc.
