How many years passed between the building of the aqua appia and the completion of the pantheon

In response to the probable growing need for water, the censor Appius Claudius Caecus built the Aqua Appia in 312 BC. It was the procedure in Rome to entrust to the two 'censors' during their eighteen months of office the building of public works.

        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!
