What argument did Scott use to sue for his freedom?
O Living in a free state should make him a free
man.
The death of his slaveholder should make
him free
O Slavery should not be allowed in the west.

Living in a free state should make him a free man.

Explanation:

In the landmark case Dread Scott v. Sandford, known as Dread Scott case, the enslaved African American man, Dred Scott fought for his freedom. Scott was born into slavery in Virginia but had been living in Illinois and Wisconsin with his owners for more than four years at the time of the case in 1846. He demanded his freedom on the grounds that these two states declared Missouri Compromise, and prohibited slavery, which would mean Scott is living as a free man in a free state.

The case reached US Supreme Court which declared that the constitution does not claim citizenship for African Americans, whether they are free or slaves, which would mean Scott can’t fight for his rights and he does not have a claim over them. The court, therefore, declared black people aren’t US citizens and never could gain their rights as one.

This decision was one of the contributing factors to the outbreak of the American Civil War in 1861.

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
