What is the central idea of the Gettysburg Address?

• A. To declare independence
• B. The war is a test to preserve the nation and advance the idea that all people deserve equality and self-government
• C. The war was about economic differences
• D. The speech called for immediate secession

Answer: (B)

The central idea being tested is that the Civil War is a test of whether the United States can endure as a nation dedicated to self-government and to the principle of equality for all. In the Gettysburg Address, Lincoln reframes the war as more than a military struggle; it’s a moment to prove whether a country conceived in liberty can survive when tested by war. He stresses that the soldiers’ sacrifices are for a nation where government is by the people and for the people, and where “new birth of freedom” means extending equality and self-government to all. This is why the option describing the war as a test to preserve the nation and advance the idea of equality and self-government fits best. The other ideas—independence, economic differences, or immediate secession—don’t capture the speech’s focus on preserving democracy and the nation's founding ideals.
