Explanation:

For Question 8: John Brown was an abolitionist. His plan at Harper's Ferry was to seize weapons (the federal armory there) and then use those weapons to arm enslaved people to start a revolt against slavery in the South. He was not against violence (he used it in his anti - slavery activities like in Kansas), there was no connection to forcing Kansas statehood or holding the Supreme Court hostage.
For Question 9: Uncle Tom's Cabin by Harriet Beecher Stowe was a novel that depicted the harsh realities of slavery, which made it very popular in the 1850s. Common Sense was about American independence (1776), John Brown's Body is a later poem (1927) inspired by John Brown, and The Dred Scott Conspiracy is not a well - known work related to showing the evils of slavery in the 1850s in the same vein as Uncle Tom's Cabin.

Answer:

Question 8: To start a slave revolt in the South.
Question 9: Uncle Tom's Cabin.
