"if history predicts behavior, is there any cause for concern today?" its a question in my essay where we find similarities between the Dark ages and now.
You know how they say history repeats itself? In that way it "predicts behavior". What that question is asking is based on what you study and find on the dark ages, what sort of things would make you concerned for today if history were to repeat itself and happen in your time?
Or whether you would be concerned at all with what you find.
