The question has a definition word of "copperheads" which is something they want you to define. So if you rearrange the question, it can be a multiple choice question stating: 
Copperheads were midwesterners who sympathized with the south and objected to
A) abolition
B) slavery 
Abolition is to over throw something and start a new version of what has been overthrown 
Slavery was the ownership of African Americans (seeing as this question was linked to the civil war)
