Answer:
Every or all the thirteen states
Explanation:
In the United States, following the War of Independence, the Americans came together to form the Articles of Confederation in 1777 among the thirteen states.
In it, there was no executive branch, no judiciary branch, and each colony has one vote each. To pass a law requires 9 of 13, while to change articles requires all the states to give consent.
Hence, Under the Articles of Confederation, representatives needed ALL THE 13 STATES agreement to change something, and we know that getting everyone to agree is really difficult.
The immediate cause of World War I that made the aforementioned items come into play (alliances, imperialism, militarism, nationalism) was the assassination of Archduke Franz Ferdinand of Austria-Hungary. ... This assassination led to Austria-Hungary declaring war on Serbia.
