Question

a direct result of the battle of fort sumter was that

lincoln only asked northern states to supply troops.
confederate states refused to send troops to the us army.
six additional states seceded from the union.
lincoln called for volunteers for the us navy.

Explanation:

Analyze the immediate aftermath of Fort Sumter

Following the Battle of Fort Sumter in April 1861, President Abraham Lincoln issued a proclamation calling for 75,000 volunteers from all remaining states in the Union to suppress the rebellion. This call to arms forced the states of the Upper South to choose sides, marking the formal Outbreak of the Civil War.

Evaluate the response of the Southern states

Because Lincoln called on all states to supply troops to put down the rebellion, the slave states of the Upper South that had not yet seceded faced a critical decision. Rather than take up arms against their fellow Southern states, several of these states chose secession.

Assess the specific state actions

Specifically, four additional states—Virginia, Arkansas, North Carolina, and Tennessee—seceded from the Union directly in response to Lincoln's call for troops following the battle. This action is represented by the option stating that Confederate states refused to send troops to the US Army, as they chose secession instead of complying with the federal demand.

Eliminate incorrect options

• Lincoln did not only ask Northern states; his call went out to all states remaining in the Union, including the slave states of the Upper South.
• Exactly four additional states seceded, not six.
• Lincoln called for volunteers for the militia (land forces/Army), not specifically the US Navy.
• Therefore, the refusal of these Southern states to supply troops to the US Army (and their subsequent secession) is the most accurate direct result.

Answer:

• Lincoln only asked Northern states to supply troops.
• Confederate states refused to send troops to the US Army. (Correct answer)
• Six additional states seceded from the Union.
• Lincoln called for volunteers for the US Navy.
