Problem: Neoclassical architecture:

At the same time the Empire style in France was a more grandiose wave of neoclassicism in architecture and the decorative arts. Mainly based on Imperial Roman styles, it originated in, and took its name from, the rule of Napoleon I in the First French Empire, where it was intended to idealize Napoleon's leadership and the French state. The style corresponds to the more bourgeois Biedermeier style in the German-speaking lands, Federal style in the United States, the Regency style in Britain, and the Napoleonstil in Sweden. According to the art historian Hugh Honour "so far from being, as is sometimes supposed, the culmination of the Neo-classical movement, the Empire marks its rapid decline and transformation back once more into a mere antique revival, drained of all the high-minded ideas and force of conviction that had inspired its masterpieces".

What was the corresponding style to Empire in Britain?

A: Regency

Problem: In 1566, the first police investigator of Rio de Janeiro was recruited. By the 17th century, most captaincies already had local units with law enforcement functions. On July 9, 1775 a Cavalry Regiment was created in the state of Minas Gerais for maintaining law and order. In 1808, the Portuguese royal family relocated to Brazil, because of the French invasion of Portugal. King Joao VI established the "Intendencia Geral de Policia" (General Police Intendancy) for investigations. He also created a Royal Police Guard for Rio de Janeiro in 1809. In 1831, after independence, each province started organizing its local "military police", with order maintenance tasks. The Federal Railroad Police was created in 1852.
Who invaded Portugal in 1808?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1718, at the behest of either Rector Samuel Andrew or the colony's Governor Gurdon Saltonstall, Cotton Mather contacted a successful businessman named Elihu Yale, who lived in Wales but had been born in Boston and whose father, David, had been one of the original settlers in New Haven, to ask him for financial help in constructing a new building for the college. Through the persuasion of Jeremiah Dummer, Yale, who had made a fortune through trade while living in Madras as a representative of the East India Company, donated nine bales of goods, which were sold for more than 560, a substantial sum at the time. Cotton Mather suggested that the school change its name to Yale College. Meanwhile, a Harvard graduate working in England convinced some 180 prominent intellectuals that they should donate books to Yale. The 1714 shipment of 500 books represented the best of modern English literature, science, philosophy and theology. It had a profound effect on intellectuals at Yale. Undergraduate Jonathan Edwards discovered John Locke's works and developed his original theology known as the "new divinity." In 1722 the Rector and six of his friends, who had a study group to discuss the new ideas, announced that they had given up Calvinism, become Arminians, and joined the Church of England. They were ordained in England and returned to the colonies as missionaries for the Anglican faith. Thomas Clapp became president in 1745, and struggled to return the college to Calvinist orthodoxy; but he did not close the library. Other students found Deist books in the library.
What was Elihu Yale's father's nickname?
A: unanswerable

Context and question: In 1955 American nuclear arms policy became one aimed primarily at arms control as opposed to disarmament. The failure of negotiations over arms until 1955 was due mainly to the refusal of the Russians to permit any sort of inspections. In talks located in London that year, they expressed a willingness to discuss inspections; the tables were then turned on Eisenhower, when he responded with an unwillingness on the part of the U.S. to permit inspections. In May of that year the Russians agreed to sign a treaty giving independence to Austria, and paved the way for a Geneva summit with the U.S., U.K. and France. At the Geneva Conference Eisenhower presented a proposal called "Open Skies" to facilitate disarmament, which included plans for Russia and the U.S. to provide mutual access to each other's skies for open surveillance of military infrastructure. Russian leader Nikita Khrushchev dismissed the proposal out of hand.
In what city did the US and Russia conduct nuclear talks in 1955?
Answer: London

Question: Beer is the world's most widely consumed and likely the oldest alcoholic beverage; it is the third most popular drink overall, after water and tea. The production of beer is called brewing, which involves the fermentation of starches, mainly derived from cereal grainsmost commonly malted barley, although wheat, maize (corn), and rice are widely used. Most beer is flavoured with hops, which add bitterness and act as a natural preservative, though other flavourings such as herbs or fruit may occasionally be included. The fermentation process causes a natural carbonation effect which is often removed during processing, and replaced with forced carbonation. Some of humanity's earliest known writings refer to the production and distribution of beer: the Code of Hammurabi included laws regulating beer and beer parlours, and "The Hymn to Ninkasi", a prayer to the Mesopotamian goddess of beer, served as both a prayer and as a method of remembering the recipe for beer in a culture with few literate people.
Is there an answer to this question: What prayer did people use in Mesopotamia to remember a beer recipe?

Answer: The Hymn to Ninkasi

Problem: Elevator:

The first elevator shaft preceded the first elevator by four years. Construction for Peter Cooper's Cooper Union Foundation building in New York began in 1853. An elevator shaft was included in the design, because Cooper was confident that a safe passenger elevator would soon be invented. The shaft was cylindrical because Cooper thought it was the most efficient design. Later, Otis designed a special elevator for the building. Today the Otis Elevator Company, now a subsidiary of United Technologies Corporation, is the world's largest manufacturer of vertical transport systems.

Which was built first, the first elevator shaft or the first elevator?
---
A:
first elevator shaft
