A war between the United States and England from 1812 to 1814.

• A. Act of Union
• B. Confederation
• C. Northwest Company
• D. War of 1812

Answer: (D)

The main idea is identifying a specific historical conflict between the United States and Britain in the early 1800s. The best fit for this description is the War of 1812. It lasted from 1812 into 1814 (with the war effectively ending in 1814 and the Treaty of Ghent signed in December 1814; news reached the United States in 1815), and it grew out of tensions over impressment of American sailors, trade restrictions, and disputes on the western frontier. This event is widely known by the name War of 1812, which is why it fits the description exactly. The other options point to things that are not wars: an Act of Union was the 1800 law uniting Great Britain and Ireland; Confederation is a term for political union, such as Canada’s in 1867; the Northwest Company was a fur-trading business active in that era, not a war.
