Why did the egyptians spend years and many resources to build enormous tombs to their dead pharohs ?

because pharaohs believe that they had an eternal spirit that allowed them to rule the land after their death.  

so these kings built themselves magnificent tombs.  

like a afterlife.

answer; andrew jackson approved nullification by signing it into law,and john calhoun opposed it saying it was unconstitutional;

        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!
