Answer 1

Based on the chart, the correct response is: The slave population roughly doubled as several new slave states were admitted to the Union.

From 1820 to 1850, the number of enslaved people in the United States increased from 1,539,038 to 3,204,313, indicating a significant rise in the slave population during this period, which corresponds with the admission of new slave states and westward expansion.
