Problem: Separation of powers under the United States Constitution:

The Constitution does not explicitly indicate the pre-eminence of any particular branch of government. However, James Madison wrote in Federalist 51, regarding the ability of each branch to defend itself from actions by the others, that "it is not possible to give to each department an equal power of self-defense. In republican government, the legislative authority necessarily predominates."

Which document explicitly indicates pre-eminence of the executive branch of government?

A: unanswerable


Problem: Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy, accounting for 16 percent of global electricity generation – 3,427 terawatt-hours of electricity production in 2010, and is expected to increase about 3.1% each year for the next 25 years. Hydroelectric plants have the advantage of being long-lived and many existing plants have operated for more than 100 years.
 What is the least widely used form of renewable energy?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
It is easy for Western-educated scholars to fall into the trap of viewing hunter-gatherer social and sexual arrangements in the light of Western values.[editorializing] One common arrangement is the sexual division of labour, with women doing most of the gathering, while men concentrate on big game hunting. It might be imagined that this arrangement oppresses women, keeping them in the domestic sphere. However, according to some observers, hunter-gatherer women would not understand this interpretation. Since childcare is collective, with every baby having multiple mothers and male carers, the domestic sphere is not atomised or privatised but an empowering place to be.[citation needed] In all hunter-gatherer societies, women appreciate the meat brought back to camp by men. An illustrative account is Megan Biesele's study of the southern African Ju/'hoan, 'Women Like Meat'. Recent archaeological research suggests that the sexual division of labor was the fundamental organisational innovation that gave Homo sapiens the edge over the Neanderthals, allowing our ancestors to migrate from Africa and spread across the globe.
Who does most of the gathering in a hunter-gatherer society?
A: women


Context and question: IMF's forecast said that Greece's unemployment rate would hit the highest 14.8 percent in 2012 and decrease to 14.1 in 2014.  But in fact, the Greek economy suffered a prolonged high unemployemnt. The unemployment figure was between 9 per cent and 11 per cent in 2009, and it soared to 28 per cent in 2013. In 2015, Greece's jobless rate is around 24 per cent. It is thought that Greece's potential output has been eroded by this prolonged massive unemployment due to the associated hysteresis effects.
What did IMF forecast Greece's employment rate to be in 2010?
Answer: unanswerable


Question: After the expulsion of the German population ethnic Russians, Belarusians, and Ukrainians were settled in the northern part. In the Soviet part of the region, a policy of eliminating all remnants of German history was pursued. All German place names were replaced by new Russian names. The exclave was a military zone, which was closed to foreigners; Soviet citizens could only enter with special permission. In 1967 the remnants of Königsberg Castle were demolished on the orders of Leonid Brezhnev to make way for a new "House of the Soviets".
Is there an answer to this question: In what year was the new "House of the Soviets" completed?

Answer: unanswerable


QUES: The Bohr magneton and the nuclear magneton are units which are used to describe the magnetic properties of the electron and atomic nuclei respectively. The Bohr magneton is the magnetic moment which would be expected for an electron if it behaved as a spinning charge according to classical electrodynamics. It is defined in terms of the reduced Planck constant, the elementary charge and the electron mass, all of which depend on the Planck constant: the final dependence on h1/2 (r2 > 0.995) can be found by expanding the variables.

What three terms define the Bohr nucleus value?
