So if you look back up at those answers, and I said we're down to three answers now, which one of those three seems most insignificant in relationship to the other ones? So is it kind of class struggle, war and conflict, or increasing prosperity brought about by industrialization? And I think that you heard it, that that third one, right, that increasing prosperity brought about industrialization, that's not as big as the other ones. That would be like a washcloth. Like I could scrub my elbow with that, but not my whole body. That's creepy. But definitely, using process of elimination, we've gotten that bad boy down that maybe you had no idea about down to two answers.
