Question

1. choose the best answer.

sectional disputes centered on slavery and ___.
tobacco
ecology
tariffs

Explanation:

In 19th-century U.S. sectional conflicts, alongside slavery, tariffs were a major point of tension. Northern industrialists supported high tariffs to protect domestic manufacturing, while Southern agricultural economies relied on imported goods and opposed high tariffs, seeing them as unfair. Tobacco was a cash crop tied to slavery but not a core sectional dispute on its own, and ecology was not a relevant issue in this historical context.

Answer:

tariffs
