Final answer:
The issue debated in Dred Scott v. Sandford was whether a person of African descent could become a citizen and have rights guaranteed by the Constitution.
Step-by-step explanation:
The issue being debated in Dred Scott v. Sandford was whether a person of African descent, who was brought to the United States as a slave, could become a citizen and be entitled to the rights and privileges guaranteed by the Constitution.
Judge Taney's ruling argued that African-Americans, regardless of their status as free or enslaved, could not be citizens and did not have the same rights as white citizens. This ruling reinforced and upheld the institution of slavery.
This case was significant in the history of the United States as it deepened the divide between the North and the South, ultimately contributing to the tensions that led to the American Civil War.
