After the Scott v. Sandford ruling, many people in the North believed that 1) slavery might become legal everywhere. 2) slavery might be banned everywhere. 3) formerly enslaved people would move to the North. 4) formerly enslaved people would stay in the South.

The correct answer is 1. After the Scott v. Sandford ruling, many people in the North believed that slavery might become legal everywhere.

Explanation:

The Supreme Court ruling in Dred Scott v. Sandford of 1857 determined that African Americans were not regarded as citizens of the United States, voiding the Missouri Compromise of 1820 and relegating African American slaves to a position of mere ownership with respect to their white owners.

Thus, given that an organ of the federal government (the United States Supreme Court) with jurisdiction throughout the national territory had established this situation with respect to African-American inhabitants, many people throughout the country began to think that the government federal would authorize a further expansion of slavery in the American territory.
