What was the main significance of the Missouri Compromise (1820)?
- A. It let settlers in each western territory decide on slavery for themselves through popular sovereignty
- B. It admitted California as a free state in return for a tougher federal fugitive slave law for the South
- C. It admitted Missouri as a slave state and Maine as free, and banned slavery north of 36°30′ ✓
- D. It ended the Atlantic slave trade by banning all imports of enslaved people into the United States after 1820
Correct answer: C. Missouri entered as a slave state, Maine as a free state, and the 36°30′ line closed the northern Louisiana Purchase lands to slavery. It calmed the crisis but showed how explosive slavery's expansion had become.
Why was McCulloch v. Maryland (1819) a significant Supreme Court decision?
- A. It protected private contracts, such as a college charter, from being changed by state legislatures
- B. It gave Congress power over interstate commerce and broke up New York's steamboat monopoly
- C. It upheld the Second Bank under implied powers and barred states from taxing a federal bank ✓
- D. It established judicial review, the Court's power to strike down acts of Congress as unconstitutional
Correct answer: C. Marshall used the necessary and proper clause (implied powers) to uphold the Bank and ruled that 'the power to tax involves the power to destroy,' so Maryland could not tax a federal institution.
Which best describes the significance of the Panic of 1819?
- A. It led Congress to abolish the Second Bank of the United States and return to state banks
- B. It began when the Embargo Act shut down New England shipping and threw sailors out of work
- C. It was set off by Jackson's Specie Circular, which forced buyers of public land to pay in gold or silver
- D. It was the first major U.S. depression, and westerners blamed the Second Bank for it ✓
Correct answer: D. After a postwar boom in land speculation, the Second Bank tightened credit, banks failed and farms were foreclosed. The resentment in the West fed later hostility to the Bank, which Jackson tapped.
Gibbons v. Ogden (1824) mattered for the U.S. economy mainly because it
- A. affirmed federal power over interstate commerce, breaking a steamboat monopoly ✓
- B. ruled that the Second Bank of the United States was constitutional under the elastic clause
- C. allowed states to charter new businesses that competed with older monopoly charters
- D. declared that the Cherokee Nation was a sovereign nation that Georgia law could not reach
Correct answer: A. By ruling that New York could not grant a monopoly over interstate waterways, Marshall's Court boosted competition and national transportation during the market revolution.
The 'Era of Good Feelings' under President James Monroe got its name mainly because
- A. the national economy grew steadily for a decade without a single downturn
- B. the Federalist Party had collapsed, leaving the Republicans with no national rival ✓
- C. Congress had finally settled the sectional quarrels over slavery and tariffs for good
- D. the United States and Great Britain signed a military alliance against Spain
Correct answer: B. After the Hartford Convention discredited the Federalists, Monroe ran nearly unopposed in 1820. One-party rule hid rising sectional tension rather than ending it.
