What is the concept of "nullification"?

The concept of nullification is a "legal theory that a state has the right to nullify, or invalidate, any federal law which that state has deemed unconstitutional with respect to the United States Constitution (as opposed to the state's own constitution)."

just like you man, i personally think its either c or d

explanation:

but good luck with the test man

        i'm fairly sure that the correct answers are 2 and 3.

        i used both my knowledge of world history and the process of elimination to obtain these answers. option 1 cannot be a possible selection because the mandate of heaven belongs to ancient chinese philosophical belief. option 4 sounds like it would benefit the region than detriment it. however, both 2 and 3 explain a potential reason for what could have contributed to the fall of the roman empire.

      hope this ! if i were you, i'd get a second opinion, because i haven't taken this course for a year. best of luck!
