Problem: This article: Oklahoma is between the Great Plains and the Ozark Plateau in the Gulf of Mexico watershed, generally sloping from the high plains of its western boundary to the low wetlands of its southeastern boundary. Its highest and lowest points follow this trend, with its highest peak, Black Mesa, at 4,973 feet (1,516 m) above sea level, situated near its far northwest corner in the Oklahoma Panhandle. The state's lowest point is on the Little River near its far southeastern boundary near the town of Idabel, which dips to 289 feet (88 m) above sea level. Among the most geographically diverse states, Oklahoma is one of four to harbor more than 10 distinct ecological regions, with 11 in its bordersmore per square mile than in any other state. Its western and eastern halves, however, are marked by extreme differences in geographical diversity: Eastern Oklahoma touches eight ecological regions and its western half contains three. Although having fewer ecological regions Western Oklahoma contains many rare, relic species. Oklahoma has four primary mountain ranges: the Ouachita Mountains, the Arbuckle Mountains, the Wichita Mountains, and the Ozark Mountains. Contained within the U.S. Interior Highlands region, the Ozark and Ouachita Mountains are the only major mountainous region between the Rocky Mountains and the Appalachians. A portion of the Flint Hills stretches into north-central Oklahoma, and near the state's eastern border, The Oklahoma Tourism & Recreation Department regards Cavanal Hill as the world's tallest hill; at 1,999 feet (609 m), it fails their definition of a mountain by one foot.The semi-arid high plains in the state's northwestern corner harbor few natural forests; the region has a rolling to flat landscape with intermittent canyons and mesa ranges like the Glass Mountains. Partial plains interrupted by small, sky island mountain ranges like the Antelope Hills and the Wichita Mountains dot southwestern Oklahoma; transitional prairie and oak savannas cover the central portion of the state. The Ozark and... contains an answer for the question: What fails the definition of a mountain by one foot?, what is it ?

A: Cavanal Hill

Problem: This article: Bowie's songs and stagecraft brought a new dimension to popular music in the early 1970s, strongly influencing both its immediate forms and its subsequent development. Bowie was a pioneer of glam rock, according to music historians Schinder and Schwartz, who credited Marc Bolan and Bowie with creating the genre. At the same time, he inspired the innovators of the punk rock music movement. When punk musicians were "noisily reclaiming the three-minute pop song in a show of public defiance", biographer David Buckley wrote that "Bowie almost completely abandoned traditional rock instrumentation." Bowie's record company promoted his unique status in popular music with the slogan, "There's old wave, there's new wave, and there's David Bowie".Musicologist James Perone credited Bowie with having "brought sophistication to rock music", and critical reviews frequently acknowledged the intellectual depth of his work and influence. The Human League founder Martyn Ware remarked that he had lived his life "as though he were an art installation." The BBC's arts editor Will Gompertz likened Bowie to Pablo Picasso, writing that he was "an innovative, visionary, restless artist who synthesised complex avant garde concepts into beautifully coherent works that touched the hearts and minds of millions". U2 lead singer Bono commented, "I like Bowie when he's evenly pulled in the direction of being a pop star and Picasso, where he's right down the middle. That's usually my favorite, when the songwriting is disciplined but the recording is not. I love when he's pulled equally in the directions of art and populism."Broadcaster John Peel contrasted Bowie with his progressive rock contemporaries, arguing that Bowie was "an interesting kind of fringe figure... on the outskirts of things". Peel said he "liked the idea of him reinventing himself... the one distinguishing feature about early-70s progressive rock was that it didn't progress. Before Bowie came along, people didn't want too much change". Buckley called the era "bloated,... contains an answer for the question: What is the full name of the person who Martyn Ware remarked had lived his life "as though he were an art installation"?, what is it ?

A: David Bowie

Problem: This article: Most historians describe the contacts between the Mongol Empire and the Western Europeans as a series of attempts, missed opportunities, and failed negotiations. Christopher Atwood, in the 2004 Encyclopedia of Mongolia and the Mongol Empire, summed up the relations between Western Europe and the Mongols: "Despite numerous envoys and the obvious logic of an alliance against mutual enemies, the papacy and the Crusaders never achieved the often-proposed alliance against Islam."A few other historians argue there was an actual alliance, but do not agree on the details: Jean Richard wrote that an alliance began around 1263. Reuven Amitai stated that the closest thing to actual Mongol-Frankish military coordination was when Prince Edward of England attempted to coordinate activities with Abaga in 1271. Amitai also mentioned the other attempts towards cooperation, but said, "In none of these episodes, however, can we speak of Mongols and troops from the Frankish West being on the Syrian mainland at the same time." Timothy May described the alliance as having its peak at the Council of Lyon in 1274, but that it began to unravel in 1275 with the death of Bohemond, and May too admitted that the forces never engaged in joint operations. Alain Demurger, in his own book The Last Templar, said that an alliance was not sealed until 1300.There also continues to be debate about whether or not an alliance would have been a wise idea, and whether the Crusaders at that point in history were even relevant to the Persian-Mongol conflict. The 20th-century historian Glenn Burger said, "The refusal of the Latin Christian states in the area to follow Hethum's example and adapt to changing conditions by allying themselves with the new Mongol empire must stand as one of the saddest of the many failures of Outremer." This was similar to the view of Steven Runciman, who argued, "Had the Mongol alliance been achieved and honestly implemented by the West, the existence of Outremer would almost certainly have been prolonged. The Mameluks... contains an answer for the question: Who did Jean Richard claim had an alliance around 1263?, what is it ?

A:
Mongol Empire
