Answer:

Explanation:
Mercantilism is an economic policy that thrived beginning in the 1500s. It was one of the driving forces behind colonization and imperialism.
- A country wanted to gain as much wealth as possible. One way to accomplish this goal was to implant a<u> </u><u><em>favorable balance of trade</em></u>. This meant the country exported more goods (sold) than it imported (bought). Essentially, the wealth flowing into the nation was greater than the money leaving.
- The countries needed a way to create this balance. So, they began to colonize. <u><em>Colonie</em></u><em>s </em>were incredibly valuable because they had natural resources. The mother country extracted the resources from the colony, produced goods in the country, and then sold them back to the colony. This practice maximized their wealth, gold, silver, and power.
The best answer choice must be D. Build the nation's gold and silver reserves by exporting more goods than it imported.
The answer to this question is false!
At the time, the Lousiana Purchase doubled the size of the United States giving her power and resources(land, water, trade routes, minerals). It also gave America access to the ports in the area greatly aiding trade. The land had belonged to France before it was sold to America, so the purchase removed their presence in the area for the most part. It also fixed ties with France who had previously asked for aid in the French Revolution to which America said no; giving France money in the form of this purchase healed the connection slightly.
The Oregon territory officially belonged to Britain, but was mostly inhabited by Native Americans. It was a very large area that caused many disputes between the European colonists due to the fur-trade. America gained the land (segments of present-day Idaho, Oregon, Washington, Wyoming, and Montana) in 1859 when Oregon officially became a state. Many Native Americans were also sent here as America continued to gain territory. The giving over of the land was used to settle the boundary dispute between America and Britain.
