I would think it would be C. The revolutionary war was mainly between the colonist in America and England, so if Historian A thinks that the war was caused by the Americans then it is likely that they are British. If historian B thinks that the war was caused by the British, then it is likely that they are American.
Answer:
During World War II, thousands of Japanese Americans living near the West Coast were forced to move to isolated internment camps deep inside the United States.
The Greeks and Romans used weapons as props, while people in the Renaissance did not.
I think because if one person held a monopoly on (let's say clothes) it provides less variety for everyone as well as essentially they get all of the revenue and smaller (family owned and such stores) businesses go out of business or bought by the bigger businesses. (Also think of the board game Monopoly, when someone owns a lot of places that cost a lot and people land on it, they pay a lot. Then someone runs out of money and has to sell the property, meaning less of a chance for them to make money and those with money now buy the available land, increasing their chances of getting money) (So essentially the rich get richer and the poor get poorer and there is a large wealth disparity)
Hope this explanation helps. If not, I could try to elaborate.
