The two correct answers are; The invention of the cotton gin and westward expansion.
Further Explanation:
The cotton gin helped to take the seeds out of the cotton, but it increased the need for plantation owners to have more slaves. Since the work was done faster with the gin, they needed more slaves to keep up the work. This caused political debates to abolish slavery, but it still took a long time to get slavery abolished.
The Westward expansion also increased the need for slaves. With so many people leaving the East coast, they needed slaves to help families cook, wash, and do many other things. This also got the political debates started and in the right direction, but it would still not end slavery altogether.
