Question: In military affairs, the use of infantry with specialised roles increased. Along with the still-dominant heavy cavalry, armies often included mounted and infantry crossbowmen, as well as sappers and engineers. Crossbows, which had been known in Late Antiquity, increased in use partly because of the increase in siege warfare in the 10th and 11th centuries.[AB] The increasing use of crossbows during the 12th and 13th centuries led to the use of closed-face helmets, heavy body armour, as well as horse armour. Gunpowder was known in Europe by the mid-13th century with a recorded use in European warfare by the English against the Scots in 1304, although it was merely used as an explosive and not as a weapon. Cannon were being used for sieges in the 1320s, and hand-held guns were in use by the 1360s.
Is there an answer to this question: What led to the increased use of armor in the 12th century?

Answer: The increasing use of crossbows

Question: Louis did not leave a son as heir after his death in 1382. Instead, he named as his heir the young prince Sigismund of Luxemburg, who was 11 years old. The Hungarian nobility did not accept his claim, and the result was an internal war. Sigismund eventually achieved total control of Hungary and established his court in Buda and Visegrad. Both palaces were rebuilt and improved, and were considered the richest of the time in Europe. Inheriting the throne of Bohemia and the Holy Roman Empire, Sigismund continued conducting his politics from Hungary, but he was kept busy fighting the Hussites and the Ottoman Empire, which was becoming a menace to Europe in the beginning of the 15th century.
Is there an answer to this question: Upon taking the throne of Hungary where didn't Sigismund establish his court?

Answer: unanswerable

Question: In the nineteenth century Burke was praised by both liberals and conservatives. Burke's friend Philip Francis wrote that Burke "was a man who truly & prophetically foresaw all the consequences which would rise from the adoption of the French principles" but because Burke wrote with so much passion, people were doubtful of his arguments. William Windham spoke from the same bench in the House of Commons as Burke had, when he had separated from Fox, and an observer said Windham spoke "like the ghost of Burke" when he made a speech against peace with France in 1801. William Hazlitt, a political opponent of Burke, regarded him as amongst his three favourite writers (the others being Junius and Rousseau), and made it "a test of the sense and candour of any one belonging to the opposite party, whether he allowed Burke to be a great man". William Wordsworth was originally a supporter of the French Revolution and attacked Burke in 'A Letter to the Bishop of Llandaff' (1793), but by the early nineteenth century he had changed his mind and came to admire Burke. In his Two Addresses to the Freeholders of Westmorland Wordsworth called Burke "the most sagacious Politician of his age" whose predictions "time has verified". He later revised his poem The Prelude to include praise of Burke ("Genius of Burke! forgive the pen seduced/By specious wonders") and portrayed him as an old oak. Samuel Taylor Coleridge came to have a similar conversion: he had criticised Burke in The Watchman, but in his Friend (180910) Coleridge defended Burke from charges of inconsistency. Later, in his Biographia Literaria (1817) Coleridge hails Burke as a prophet and praises Burke for referring "habitually to principles. He was a scientific statesman; and therefore a seer". Henry Brougham wrote of Burke: "... all his predictions, save one momentary expression, had been more than fulfilled: anarchy and bloodshed had borne sway in France; conquest and convulsion had desolated Europe...the providence of mortals is not often able to penetrate so far as this into futurity". George Canning believed that Burke's Reflections "has been justified by the course of subsequent events; and almost every prophecy has been strictly fulfilled". In 1823 Canning wrote that he took Burke's "last works and words [as] the manual of my politics". The Conservative Prime Minister Benjamin Disraeli "was deeply penetrated with the spirit and sentiment of Burke's later writings".

Question: Collegiate athletics are a popular draw in the state. The state has four schools that compete at the highest level of college sports, NCAA Division I. The most prominent are the state's two members of the Big 12 Conference, one of the so-called Power Five conferences of the top tier of college football, Division I FBS. The University of Oklahoma and Oklahoma State University average well over 50,000 fans attending their football games, and Oklahoma's football program ranked 12th in attendance among American colleges in 2010, with an average of 84,738 people attending its home games. The two universities meet several times each year in rivalry matches known as the Bedlam Series, which are some of the greatest sporting draws to the state. Sports Illustrated magazine rates Oklahoma and Oklahoma State among the top colleges for athletics in the nation. Two private institutions in Tulsa, the University of Tulsa and Oral Roberts University; are also Division I members. Tulsa competes in FBS football and other sports in the American Athletic Conference, while Oral Roberts, which does not sponsor football, is a member of The Summit League. In addition, 12 of the state's smaller colleges and universities compete in NCAA Division II as members of four different conferences, and eight other Oklahoma institutions participate in the NAIA, mostly within the Sooner Athletic Conference.
