Since this question makes zero sense let me answer it to the best of my abilities, first off Rome was at it's most powerful during the time 117AD or during Emperor Hadrians Time. This is also the time where they built Hadrian's Wall, (which can be found in northern England). At this point Rome controlled almost the entire part of Europe, half of Britain, some of Africa, and plenty of the middle east. I would link a picture but that's forbidden on this site for some reason... Look up in google (117AD Rome)
D. John C Calhoun. He was a major advocate for states rights, partly because he believed that states could decide for themselves if they allowed slavery, separated from the federal’s governments legal power.
The Anti-Federalists argued that the Constitution gave too much power to the federal government, while taking too much power away from state and local governments.
Farming in the United States changed in many ways in the late 1800's:
A. <em>The amount of money in circulation increased</em>. Incorrect. Many farmers kept their money or saved it, there was really no circulation happening.
B. <em>Farmers used new equipment</em>. <u>Correct</u>. This is where the use of horses came into play to help plow fields, along with other pieces of equipment that made it easier to farm.
C.<em> Larger farms produced a single crop</em>. <u>Correct</u>. It was less work if a farm just had one crop, so larger farms would usually just pick one that was in high demand.
D. <em>World competition decreased</em>. Incorrect. The world competition did not decrease because of farming. World competition did maybe decrease for the farmers, but not in general.
