The American System is associated with which three components?

• A. Tariffs to protect industry, a national bank, and internal improvements
• B. Free trade, minimal government, and states' rights
• C. Expansion of slavery, annexation, and manifest destiny
• D. Isolationism, imperialism, and militarism

Answer: (A)

The main idea tested is the plan known as the American System, an early 19th-century effort to strengthen the national economy by tying together industry, money, and infrastructure. Protective tariffs would raise the cost of foreign goods, making American-made products more competitive and encouraging growth of domestic factories. A national bank would provide a stable currency and easier credit, helping businesses expand and making trade across different states more reliable. Investment in internal improvements—roads, canals, and later railways—would link regions, lower transport costs, and knit the economy into a single market.

This approach emerged after the War of 1812 as a way to promote self-sufficiency and unity among the states, with Henry Clay championing the package as a coherent program rather than isolated policies. The tariff element often aimed to protect Northern industry, while the idea of federally funded internal improvements sparked debates about the proper scope of federal power, but the overall goal remained clear: build a more integrated, prosperous national economy.

So, the combination of tariffs to shield industry, a national bank to stabilize and finance it, and federally supported internal improvements best fits what the American System is. The other options describe different political priorities and eras, not this specific economic program.
