Problem: Germans:

A German ethnicity emerged in the course of the Middle Ages, ultimately as a result of the formation of the kingdom of Germany within East Francia and later the Holy Roman Empire, beginning in the 9th century. The process was gradual and lacked any clear definition, and the use of exonyms designating "the Germans" develops only during the High Middle Ages. The title of rex teutonicum "King of the Germans" is first used in the late 11th century, by the chancery of Pope Gregory VII, to describe the future Holy Roman Emperor of the German Nation Henry IV. Natively, the term ein diutscher ("a German") is used for the people of Germany from the 12th century.

Who first used rex teutonicum?

A: Pope Gregory VII


Problem: Most of the cuisines found in Kathmandu are non-vegetarian. However, the practice of vegetarianism is not uncommon, and vegetarian cuisines can be found throughout the city. Consumption of beef is very uncommon and considered taboo in many places. Buff (meat of water buffalo) is very common. There is a strong tradition of buff consumption in Kathmandu, especially among Newars, which is not found in other parts of Nepal. Consumption of pork was considered taboo until a few decades ago. Due to the intermixing with Kirat cuisine from eastern Nepal, pork has found a place in Kathmandu dishes. A fringe population of devout Hindus and Muslims consider it taboo. The Muslims forbid eating buff as from Quran while Hindus eat all varieties except Cow's meat as the consider Cow to be a goddess and symbol of purity. The chief breakfast for locals and visitors is mostly Momo or Chowmein.
What animal does buff come from?

Answer: water buffalo


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
An alloy is a mixture of either pure or fairly pure chemical elements, which forms an impure substance (admixture) that retains the characteristics of a metal. An alloy is distinct from an impure metal, such as wrought iron, in that, with an alloy, the added impurities are usually desirable and will typically have some useful benefit. Alloys are made by mixing two or more elements; at least one of which being a metal. This is usually called the primary metal or the base metal, and the name of this metal may also be the name of the alloy. The other constituents may or may not be metals but, when mixed with the molten base, they will be soluble, dissolving into the mixture.
What other metal is pure like an alloy?
A: unanswerable


Context and question: Red is the traditional color of warning and danger. In the Middle Ages, a red flag announced that the defenders of a town or castle would fight to defend it, and a red flag hoisted by a warship meant they would show no mercy to their enemy. In Britain, in the early days of motoring, motor cars had to follow a man with a red flag who would warn horse-drawn vehicles, before the Locomotives on Highways Act 1896 abolished this law. In automobile races, the red flag is raised if there is danger to the drivers. In international football, a player who has made a serious violation of the rules is shown a red penalty card and ejected from the game.
What does a red flag signify in football?
Answer: unanswerable


Question: In Canada, the term "football" may refer to Canadian football and American football collectively, or to either sport specifically, depending on context. The two sports have shared origins and are closely related but have significant differences. In particular, Canadian football has 12 players on the field per team rather than 11; the field is roughly 10 yards wider, and 10 yards longer between end-zones that are themselves 10 yards deeper; and a team has only three downs to gain 10 yards, which results in less offensive rushing than in the American game. In the Canadian game all players on the defending team, when a down begins, must be at least 1 yard from the line of scrimmage. (The American game has a similar "neutral zone" but it is only the length of the football.)
Is there an answer to this question: An American football field is how much wider than a Canadian football field?

Answer: unanswerable


Question: The current Minority Leader Nancy Pelosi, of the United States House of Representatives serves as floor leader of the opposition party, and is the counterpart to the Majority Leader. Unlike the Majority Leader, the Minority Leader is on the ballot for Speaker of the House during the convening of the Congress.

The Minority Leader usually meets with the Majority Leader and the Speaker to discuss agreements on controversial issues.
