Question

Which statement best explains how the Kansas-Nebraska Act contributed to the tensions between the North and the South that led to the Civil War?

Answer 1

Because Kansas and Nebraska (which were both territories not states at the time) had to vote on whether they would allow slavery in their territory or not. So, supporters of slavery and those against slavery rushed to these places so they could participate in the vote. Some violence also broke out, which led the term "Bleeding Kansas".
