Answer 1

The correct answer is D. westward expansion and slavery. During the years between 1820 and 1860, the issues of westward expansion and the associated question of whether new territories would be slave or free states were central to U.S. politics. This period also saw significant debates and conflicts over the institution of slavery, leading up to the Civil War.
