Passage: Subsequent to this decision, the Supreme Court has applied a three-pronged test to determine whether government action comports with the Establishment Clause, known as the "Lemon Test". First, the law or policy must have been adopted with a neutral or non-religious purpose. Second, the principle or primary effect must be one that neither advances nor inhibits religion. Third, the statute or policy must not result in an "excessive entanglement" of government with religion. (The decision in Lemon v. Kurtzman hinged upon the conclusion that the government benefits were flowing disproportionately to Catholic schools, and that Catholic schools were an integral component of the Catholic Church's religious mission, thus the policy involved the state in an "excessive entanglement" with religion.) Failure to meet any of these criteria is a proof that the statute or policy in question violates the Establishment Clause. Question: To not violate the Establishment Clause, a law must be adopted with neutral or what purpose?
non-religious

Passage: The independence of the ECB is instrumental in maintaining price stability. Not only must the bank not seek influence, but EU institutions and national governments are bound by the treaties to respect the ECB's independence. To offer some accountability, the ECB is bound to publish reports on its activities and has to address its annual report to the European Parliament, the European Commission, the Council of the European Union and the European Council. The European Parliament also gets to question and then issue its opinion on candidates to the executive board. Question: Why do EU institutions and national governments have to respect the independence of the ECB?
bound by the treaties

Passage: Following the Battle of Hakusukinoe against Tang China and Silla in 663 AD that led to a Japanese retreat from Korean affairs, Japan underwent widespread reform. One of the most important was that of the Taika Reform, issued by Prince Naka no Oe (Emperor Tenji) in 646 AD. This edict allowed the Japanese aristocracy to adopt the Tang dynasty political structure, bureaucracy, culture, religion, and philosophy. As part of the Taiho Code, of 702 AD, and the later Yoro Code, the population was required to report regularly for census, a precursor for national conscription. With an understanding of how the population was distributed, Emperor Mommu introduced a law whereby 1 in 34 adult males was drafted into the national military. These soldiers were required to supply their own weapons, and in return were exempted from duties and taxes. This was one of the first attempts by the Imperial government to form an organized army modeled after the Chinese system. It was called "Gundan-Sei" () by later historians and is believed to have been short-lived.[citation needed] Question: When was the Taika Reform?
646 AD
