I think the three decisions made by the estates-general are the following:
a. Summoning the Estates wherein the nobles and peasants convened after they were summoned by King Louis XVI
b.The Estates-General convened and created the Edict of 24 January 1789 to tackle the current financial difficulties of France
C. After the convention, the Estate had continued to tackle the issues with proceedings and created various solutions to the ongoing debt of the country.
They were ok according to my history book
Federal government is better than unitary government because : The power is not concentrated in only in the centre but it is distributed at the state or lower levels as well. This helps to avoid conflicts.The federal system is notorious for the diffusion of authority to a point where it is impossible for citizen to assign
Hope it help
Good day ✌️
