Answer:
c) try to find new trade routes to Africa and Asia

Finding new trade routes to Africa and Asia is a good way to gain a competitive advantage over other European, rival states. This in fact what Portugal first, and later Spain, did during the later years of the 1400s.
The motivation was that the Ottoman Empire controlled the Eastern Mediterranean, and this prevented Western European nations from trading with East Asia and the Middle East with ease.
Portugal opted to look for new routes around Africa, and the Indian Ocean, while Spain decided to look for a new route throught the west, which led to the arrival of Columbus in the Americas in 1492.
In the United States, the three main factors that make up the system of checks and balances would be the Executive Branch, the Legislative Branch, and the Judicial Branch, since the goal is to separate these powers so that no single power becomes too powerful.
"The people" were originally White, Property-owning Males over 21. They were the only ones that could originally vote. The property owning portion will almost completely be gone by 1828 (this is what helped Andrew Jackson get elected). Non white men will begin being able to vote with the passing of the 15th Amendment after the Civil War. Women will earn suffrage (right to vote) in 1920 with the 19th Amendment. Lastly, we'll lower the voting age to 18 in 1971 with the 26th Amendment, due to the Vietnam War.
