The correct answer is:
Attempts to abolish slavery weakened.
The westward expansion of the United States gave new life to slavery. The expansion of slavery to the west was an important economic and social process that led to slavery to the southwest, to Mississippi, Alabama, passing the Mississippi River to Louisiana. By the 1840s, slavery had settled in Texas.
