Difficulty: HardIdeological and Legal Debates over Slavery

Read the passage below and answer the question that follows.

"If slavery is right, all words, acts, laws, and constitutions against it, are themselves wrong, and should be silenced, and swept away. If it is right, we cannot justly object to its nationality—its universality; if it is wrong, they cannot justly insist upon its extension—its universality. All they ask, we could readily grant, if we thought slavery right; all we ask, they could as readily grant, if they thought it wrong. Their thinking it right, and our thinking it wrong, is the precise fact upon which the entire controversy turns."
— Abraham Lincoln, address at Cooper Union, New York, February 27, 1860

Which of the following political developments during the 1850s best supports the argument in the excerpt that the debate over slavery had become an irreconcilable ideological conflict?

  1. A
    The broad national agreement established by the application of popular sovereignty in new territories
  2. B
    The resolution of sectional differences through compromise tariffs that satisfied Northern and Southern industrial interests
  3. The collapse of the Whig Party and the emergence of a purely sectional party systemAnswer
  4. D
    The transition of the Southern agricultural workforce from chattel slavery to contract-based indentured labor

Answer

The collapse of the Whig Party and the emergence of a purely sectional party system
The correct answer is correct because the collapse of the Whig Party and the subsequent rise of the Republican Party in the mid-1850s demonstrated that national political coalitions could no longer bridge the ideological divide over slavery. The Republican Party was a purely sectional Northern party dedicated to stopping the expansion of slavery, which Southern Democrats viewed as an existential threat. This political realignment reflected Lincoln's assertion that the debate was a fundamental, irreconcilable conflict between those who believed slavery was morally right and those who believed it was wrong.

Step-by-Step Solution

1
Analyze the source passage to identify the central argument and context.
Lincoln argues that the conflict over slavery is a fundamental, irreconcilable moral and ideological debate ('thinking it right, and our thinking it wrong') that cannot be compromised away.
Understanding the core argument is necessary to evaluate which historical development during the 1850s best supports Lincoln's claim of irreconcilability.
2
Evaluate the options to identify which development demonstrates the breakdown of national compromise and the hardening of sectional lines.
The collapse of the national Whig Party and the emergence of the Republican Party (a purely northern, sectional party) shows that national political institutions could no longer bridge the division over slavery.
A sectionalized party system is the direct political manifestation of the irreconcilable ideological divide described by Lincoln.
3
Rule out the remaining options based on historical accuracy and the error taxonomy.
Popular sovereignty did not create consensus (it caused violence); tariffs were not the primary cause of the sectional crisis; and the Southern agricultural labor force did not shift to indentured labor during this period.
Eliminating historically inaccurate or misapplied concepts confirms the correct choice.
