Which of the following events would definitely turn an unlimited government system into a limited government system?

A limited government has rules that restrict what its leaders can do. A written constitution that outlines government rules can set those limits and define the leaders’ powers, so creating one between the people and their leaders would turn an unlimited system into a limited one. War, division into separate nations, or a trade agreement does not necessarily place lasting limits on government power.
