Explanation:

Question 1 (Compromise of 1850)

The Compromise of 1850's new Fugitive Slave Law required Northerners to help capture runaway slaves, which violated their anti - slavery sentiments and was the most alarming to them. Slavery in DC was restricted, the Texas - New Mexico boundary settlement was more about land, and the Utah/New Mexico slavery decision was popular sovereignty (less alarming than the Fugitive Slave Law).

In 1855, fighting broke out in Kansas (known as "Bleeding Kansas") as pro - slavery and anti - slavery forces clashed over whether Kansas would be a slave or free state. Nebraska was part of the Kansas - Nebraska Act but the fighting was in Kansas, Missouri was a slave state without this 1855 conflict over expansion, and Arkansas was a slave state with no such 1855 conflict.

Answer:

A. the new Fugitive Slave Law

Question 2 (1855 fighting over slavery expansion)
