The answer is B: The writers of the Constitution disagreed on ideology.
The first party ever made in the U.S. was the Federalist, in 1787. Being led by Alexander Hamilton and other leaders (mainly bankers, northern businessmen, merchants, etc), they promoted the belief that Constitution was open to interpretation, thus the government had "unmentioned rights" to have additional powers, and also found necessary a strong national government and a national bank, as well as a good relationship with England.
However, a lot of people disagreed on his policies especially planters, small farmers, and artisans, therefore around a year later The Democratic-Republican party was made, led by Thomas Jefferson and James Madison. They strongly opposed to the Federalist interpretation of the Constitution as well as the idea of a strong government and leaned to give more power to the states and local governments instead. In contrast, they preferred to have a good relationship with France, and not Britain.

The Classical Era set the scene. It brought us the major civilizations, religions, and trade routes. But, what happens when all of the major world powers collapse? This is the Post-Classical era. The major world powers come from places you might not expect. There are some powers that are similar to the ones before and the ones after (Byzantine, China). But, the major players in the Post-Classical era come from totally backwards places. One sprouts out of a cave in the Arabian desert. The other comes from the base of a mountain on the steppes in Central Asia. I call this era, Muslims & Mongols. That's not everything, but it just about sums up the basics. (Of course, Trade, Migrations, Religion, and Labor are important...) The Post Classical Era is the FIRST era that represents 20% of the test. From here on out, these eras are worth more than the first two.
