It would be the development in agricultural knowledge/technology
Development in agriculture enable hunter/gatherer society to shift their behavior. Before this, they had to keep moving from one place to another in order to seek food to live.
After the development in agricultural knowledge/technology, the society now can stay in one exact place for a long period of time and relied on agricultural product as their main source food.
After living in one same place for a long time, the needs to build things to accommodate their living start to arise. They start to built several things and repeat the process every year. In the end, large cities were developed from the initially small hunter/gatherer society.
He was one of the few that did not become consumed with their fame and power over others, he started out as wanting to help the rest of the country and the power did not eat him up; he started wanting to help and ended still trying to help as opposed to being obsessed with the limelight.

Each of the continents of the planet has its own spices, but it was in Europe from the Crusades, from the eleventh century, that the consumption of these varieties from the tropical regions developed. Giving flavor to meals came to be treated as an alchemy in the more affluent homes of European families. It was because of spices that trade between the West and the East was expanded, with the creation of various land and sea routes, which united not only Europe internally, but linked it to China through the Silk Road and India, through Spice Route. Black pepper, cinnamon, nutmeg and ginger were rare treasures brought by Arabs from distant tropical areas of Asia to be marketed in Europe and the Mediterranean Sea region.
Since the Roman Empire some oriental spices were already consumed on European soil, notably black pepper. About a thousand years later, in the medieval period, Arab cultural influence added other spices to the rich tables of Europe, and demand grew in proportion to the expansion of the middle class. The growth of this trade has awakened in Portugal and Spain the interest in opening new sea routes to Asia. It was in this way that Christopher Columbus discovered America in 1492 and from there took the vanilla and various types of peppers. Then, in 1498, Vasco da Gama arrived in India, where he established, along with Spain, the trade of clove and nutmeg until 1600, when they were surpassed by the Dutch who kept control of this trade for about 200 years.
The correct answer is the Court of Appeals.
These Courts of Appeals are responsible for hearing the appeals from cases from the district courts. The Courts of Appeals, after hearing both sides of the story, are able to determine whether or not the case deserves to be overruled or brought before the Supreme Court. This helps to limit the amount of cases seen by the Supreme Court on a yearly basis.
