A. Lincoln
I think it is Lincoln because the term carpetbagger is a compliment and usually said to the Northerners who moved to the South after the Civil War took place.
Because maybe bad things will happen or if there is a war
I think it's B. the period when the Roman Empire experienced peace and prosperity
I'm not sure, but I'd say either d or b, I'd ask a parent to look over it or email your teacher for help. (:
