Answer:
She is made to leave because she is accused of "Moral Turpitude" .
(Lyddie doesn't understand it though)
The correct answer among the choices provided is the third option. Two independent clauses incorrectly joined are referred to as a fused sentence. A fused sentence is also called a run-on sentence. To correct this, an appropriate conjunction or punctuation mark must be put in between the clauses.
Since she uses the derogatory word for the Union soldiers, it is the second option.
