Hammurabi was the leader who was also known as king of the Amorites and was the first to develop a code of laws that addressed all aspects of daily life and was meant to keep order. The correct option among all the options given in the question is the third option.
Hammurabi was actually the sixth king of the first Babylonian
Dynasty and he ruled from 1792 BC to 1750 BC. He ruled the kingdom until he
died in the year 1750 BC.
It would be difficult for the United States for two reasons, the fact that none of the land was mapped other than the areas that previous voyagers had gone through, and the natural landscape of the area, and last, Native American Hostility.
Three examples: When pioneers would voyage to the west, there would often be encounters were they would be attacked by animals that had not been seen before, bears, sneaks, different wolves, and many more. They barely knew the natural resources of the area, such as food, etc.
The next example, no mapping, would be difficult because for the most part, they had no sense of navigation except for the few maps that had been made, even then, would be difficult to navigate.
Native Americans did not appreciate the pioneers coming into the land they considered their own, they resembled hostility and would even kill the civilians that would travel through the land, or capture them.
Hope this helps!! <3
