Final answer:
Henry Clay's American System aimed to improve the nation's infrastructure by setting up a national bank, implementing a protective tariff, and supporting internal transportation improvements.
Step-by-step explanation:
Henry Clay's American System was designed to improve the nation's infrastructure. The American System included plans for federally sponsored roads and canals, a national bank, and a protective tariff. The purpose of these measures was to create a more stable currency system, protect emerging American industries, and facilitate the movement of goods across the country. By establishing a bank and implementing a tariff, the system aimed to make the nation less dependent on foreign trade and raise government revenues. The emphasis on internal improvements sought to quicken the pace at which raw materials and finished goods moved within the country, thereby stimulating the economy and promoting national growth.
