Question

sectional rivalries during the period from 1820 to 1860 centered mainly around the issues of

foreign policy, the abolition of slavery, and the currency system
states rights, the extension of slavery, and tariffs
tariffs, the currency system, and trust regulation
conservation, foreign policy, and women’s suffrage

Explanation:

1. Slavery extension was the core sectional divide (free vs. slave states over new territories).
2. States' rights were tied to slavery, as Southern states argued they could override federal anti-slavery policies.
3. Tariffs split the North (protective tariffs helped manufacturing) and South (high tariffs raised costs for their imported goods).

Other options are incorrect: foreign policy, currency, trust regulation, conservation, and women's suffrage were not the main sectional issues of 1820-1860.

Answer:

States rights, the extension of slavery, and tariffs
