Answer: I think it A, but it can be C, B is also a good answer, however D is also tricky
Explanation:
Difference in policies were to blame, although the immediate cause of World War one was the assassination of Austria's Archduke Franz Ferdinand. The war started mainly because of four aspects: Militarism, Alliances, Imperialism and Nationalism. ... Nationalist groups in Austria-Hungary and Serbia wanted independence.
The correct answer is the first option.
It is in the unitary system and the unitary government that all of the key powers are in the hands of the central government. Under this system there is only one power that is the central government and any other administrative units have only so much power as the central government chooses and is willing to delegate.
Even though the Articles of Confederation had numerous flaws, it did give the United States a couple positive effects. One of them is the Northwest Ordinance of 1787.
This law was considered a success for a few different reasons:
1) It was one of the few laws passed, as nine out of thirteen states had to agree on it.
2) It allowed the US to expand their territory.
3) It resulted in the process that would later be used in order to turn territories into states.
The Northwest Ordinance laid the foundation for how territories became states. This included population requirements and the creation of a state constitution. This foundation was then used to add territories, even after the Articles of Confederation was replaced by the US Constitution.
