What type of work did camp followers do during the American
Revolution?

Camp followers contributed to the daily responsibilities of maintaining the army by performing traditionally domestic tasks. One such role was serving as washerwomen for enlisted men and officers, which was essential for hygiene and the prevention of communicable diseases among the encampments.

They made a checks and balance system to equal power within the branches. the "check" meant that one branch would watch one branch and "balance" them if they were too powerful. if you want more info on this, i would just google checks and balance system.
