I believe it's "original jurisdiction."
First you have to understand what happened in March 5, 1770 a British soldier got in an argument with a colonist then the soldier struck him, people started to gather and then yell at the soldier call him names and then they started taunting him then other soldiers started shotting people in the crowd instantly 3 people died including a salior Crispus Attucks then two days later 2 more people die. My opinion on the topic is it was sad and tragic that it was all because of an argument that got five people shot and killed.
The answer is c. Civil War. The states of the South were
against any interference from the Federal government particularly on the issue
of slavery. When Lincoln was elected,
the Southern states felt that their rights to own slaves would be jeopardized and
this would lead to Civil War.
