The correct answer to this open question is the following.
Southern reactions to the enactment of the Fugitive Slave Law were positive. Southern people welcome this legislation because it supported slavery in the South. Southern owners of large plantations heavily depended on slavery to produce the number of crops needed for internal consumption, trade, and exportation to Europe.
Comparing southern reactions to those expressed by Northerners, we can see how people from the North were against the Fugitive Slave Law because it forced them to support slavery, and northerners were abolitionists, demanding the end of slavery in the United States.
The Fugitive Slave Law was passed in 1850.
