Which option best represents two primary economic and social causes of the American Civil War?

• A. Slavery as a social cause; States' rights and economic differences
• B. Slavery alone
• C. Tariffs and currency
• D. Religion conflicts

Answer: (D)

The main idea here is that two intertwined factors explain why the Civil War began: slavery as a social and economic institution in the South, and the clash over states’ rights and regional economic differences. Slavery was not only a social system shaping daily life and political power in the slaveholding states, but it also underpinned the Southern economy. Debates over expanding or restricting slavery into new territories and states helped push the nation toward secession.

At the same time, disputes about how much authority the federal government should have (states’ rights) and the different economic paths of the North and South (industrializing, tariff-favored North vs. cotton-based, tariff-skeptical South) deepened sectional tensions. These contrasts made compromises harder and made the preservation of slavery and regional power more threatening to one side than the other.

So, the option that identifies slavery as a social cause along with disagreements over states’ rights and economic differences best captures the two primary economic and social drivers of the conflict. The other choices miss one of these essential dimensions or emphasize factors that were not central drivers of the war.
