Croen's argument that he is older and wiser than his son is an example of ethos.
Ethos is when an argument is constructed based on the ethics or credibility of the person that is making an argument. Ethos is in contrast to pathos, which appeals to emotions. Logos appears to logic or reason. Harmatia is something completely different and means when a fatal flaw leads to the downfall of a tragic hero.
I do not know the answer, but if I were to guess, that it would be the one about plantations.
Plantations were hotspots of manual labor, specifically slaves. And when slaves were outlawed the plantation owners lose there main source of “profit” (aka the need to not pay workers for manual labor and instead use that money to get more laborers) it seems like the logical answer to me.
Also using process of elimination we know that the war could have spilt the country in two. So the union was indeed saved.
The company towns reinforced it by having special wages for people of different ethnicity or by racially profiling and segregating those that they didn't want to be equal with Caucasian workers. This caused an even bigger drift between people and distrust to arise.
I believe it was John C. Frémont
Correct me if im wrong☺
Southern state that had been part of the Confederacy had to ratify the fourteenth amendment.
