Problem: Szlachta:

On 23 October 1501, at Mielnik PolishLithuanian union was reformed at the Union of Mielnik (Polish: unia mielnicka, unia piotrkowsko-mielnicka). It was there that the tradition of the coronation Sejm (Polish: "Sejm koronacyjny") was founded. Once again the middle nobility (middle in wealth, not in rank) attempted to reduce the power of the magnates with a law that made them impeachable before the Senate for malfeasance. However the Act of Mielno (Polish: Przywilej mielnicki) of 25 October did more to strengthen the magnate dominated Senate of Poland then the lesser nobility. The nobles were given the right to disobey the King or his representativesin the Latin, "non praestanda oboedientia"and to form confederations, an armed rebellion against the king or state officers if the nobles thought that the law or their legitimate privileges were being infringed.

Where was the Mielnik PolishLithuanian union refromed?

A: Union of Mielnik

Problem: Despite odds of four to one, the III Corps launched a risky attack. The French were routed and the III Corps captured Vionville, blocking any further escape attempts to the west. Once blocked from retreat, the French in the fortress of Metz had no choice but to engage in a fight that would see the last major cavalry engagement in Western Europe. The battle soon erupted, and III Corps was shattered by incessant cavalry charges, losing over half its soldiers. The German Official History recorded 15,780 casualties and French casualties of 13,761 men.
What odds were at stake for the attack launched by the III Corps?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Collectively encompassing more than 900 million adherents, or nearly forty percent of Christians worldwide, Protestantism is present on all populated continents.[t] The movement is more divided theologically and ecclesiastically than either Eastern Orthodoxy or Roman Catholicism, lacking both structural unity and central human authority. Some Protestant churches do have a worldwide scope and distribution of membership (notably, the Anglican Communion), while others are confined to a single country, or even are solitary church bodies or congregations (such as the former Prussian Union of churches). Nondenominational, evangelical, independent and other churches are on the rise, and constitute a significant part of Protestant Christianity.
Which continents have some form of Protestantism?
A: all populated continents

Context and question: In 1516, William IV, Duke of Bavaria, adopted the Reinheitsgebot (purity law), perhaps the oldest food-quality regulation still in use in the 21st century, according to which the only allowed ingredients of beer are water, hops and barley-malt. Beer produced before the Industrial Revolution continued to be made and sold on a domestic scale, although by the 7th century AD, beer was also being produced and sold by European monasteries. During the Industrial Revolution, the production of beer moved from artisanal manufacture to industrial manufacture, and domestic manufacture ceased to be significant by the end of the 19th century. The development of hydrometers and thermometers changed brewing by allowing the brewer more control of the process and greater knowledge of the results.
What did the development of hyrdrothermometers change?
Answer: unanswerable

Question: The Tower has been inextricably linked with the Everton area since its construction in 1787. It was originally used as a bridewell to incarcerate mainly drunks and minor criminals, and it still stands today on Everton Brow in Netherfield Road. The tower was accompanied by two laurel wreaths on either side and, according to the College of Arms in London, Kelly chose to include the laurels as they were the sign of winners. The crest was accompanied by the club motto, "Nil Satis Nisi Optimum", meaning "Nothing but the best is good enough".
Is there an answer to this question: What is the Everton club motto?

Answer: Nil Satis Nisi Optimum

Problem: Race and ethnicity in the United States Census:

In September 1997, during the process of revision of racial categories previously declared by OMB directive no. 15, the American Anthropological Association (AAA) recommended that OMB combine the "race" and "ethnicity" categories into one question to appear as "race/ethnicity" for the 2000 US Census. The Interagency Committee agreed, stating that "race" and "ethnicity" were not sufficiently defined and "that many respondents conceptualize 'race' and 'ethnicity' as one in the same [sic] underscor[ing] the need to consolidate these terms into one category, using a term that is more meaningful to the American people."

How did racial categories appear in the US 2000 census?

A:
