Analyze the source passage

The passage is written by John O'Sullivan in 1845, coining the term "Manifest Destiny" ("Our... destiny [is] to overspread the continent..."). It describes the westward migration of American settlers ("Anglo-Saxon emigration") into California and other western territories.

Connect the process to historical outcomes

The process of westward expansion and territorial acquisition (such as the annexation of Texas, the Oregon Treaty, and the Mexican Cession) directly forced the nation to confront whether these new lands would allow slavery. This led to intense sectional conflicts and political controversies throughout the 1840s and 1850s.

Evaluate the answer choices

• Use of natural resources: Not the primary source of national political controversy during this period.
• Authority of the Supreme Court: While the Dred Scott decision (1857) was controversial, it was a symptom of the broader debate over slavery's expansion, not the direct process described.
• Role of the federal government in economic development: This refers to debates over tariffs, banking, and internal improvements, which were secondary to the territorial slavery debates of this era.
• Expansion of slavery into newly acquired territories: This is the direct political consequence of acquiring new lands (like California) through westward expansion, leading to the Compromise of 1850, the Kansas-Nebraska Act, and the rise of sectionalism.
