This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.

Q: 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?

A: non-religious

Q: Passage: From 1920, Eisenhower served under a succession of talented generals – Fox Conner, John J. Pershing, Douglas MacArthur and George Marshall. He first became executive officer to General Conner in the Panama Canal Zone, where, joined by Mamie, he served until 1924. Under Conner's tutelage, he studied military history and theory (including Carl von Clausewitz's On War), and later cited Conner's enormous influence on his military thinking, saying in 1962 that "Fox Conner was the ablest man I ever knew." Conner's comment on Eisenhower was, "[He] is one of the most capable, efficient and loyal officers I have ever met." On Conner's recommendation, in 1925–26 he attended the Command and General Staff College at Fort Leavenworth, Kansas, where he graduated first in a class of 245 officers. He then served as a battalion commander at Fort Benning, Georgia, until 1927. Question: How many people were in Eisenhower's class at the Command and General Staff College?

A: 245

Q: Passage: Reflections generally affect polarization. For radio waves, one important reflector is the ionosphere which can change the wave's polarization. Thus for signals received following reflection by the ionosphere (a skywave), a consistent polarization cannot be expected. For line-of-sight communications or ground wave propagation, horizontally or vertically polarized transmissions generally remain in about the same polarization state at the receiving location. Matching the receiving antenna's polarization to that of the transmitter can make a very substantial difference in received signal strength. Question: What mostly affects polarization?

A:
Reflections
