PROBLEM: Question: Were the Oz books the only books L. Frank Baum ever wrote? Passage:The Land of Ev is a fictional country in the Oz books of L. Frank Baum and his successors. Its exact location is unclear between text and maps. The Road to Oz states that Ev is to the north of the Land of Oz, and in Ozma of Oz, Princess Ozma of Oz and her procession enter the Munchkin Country and meet the King of the Munchkins upon leaving the palace at Evna, the capital city. Subsequent books place Ev nearer to the Winkie Country, and the map on the endpapers of Tik-Tok of Oz shows the Munchkin Country as having no northern border with the desert that surrounds Oz, as a thin strip of the Gillikin Country extends even farther east than most of the Munchkin Country. This map depicts Ev as a small country to the northwest (the compass rose is reversed) of Oz, with the Dominions of the Nome King as a separate area. James E. Haff and Dick Martin's map, following the text, place the Nome Kingdom under an Ev that takes up the entire portion allotted to the Nome King's dominions on Baum's map.

PROBLEM: Question: How long had Prüm Abbey existed when Eygilo left to become the abbot of Flavigny? Passage:The fame of Flavigny was due partly to the relics which it preserved, and partly to the piety of its monks. The monastery was at the height of its reputation in the eighth century, in the time of the Abbot Manasses, who was appointed by Pippin the Short. In 760/62, Manasses attended the council of Attigny. Pippin's successor, Charlemagne, authorized Manasses to found the Carolingian style monastery of Corbigny. The same Manasses transferred from Volvic to Flavigny the relics of Saint Praejectus. Abbot Apollinaris, appointed by Charlemagne in 802, was also abbot of Saint-Bénigne de Dijon and Môutier-Saint-Jean. Charlemagne's son, Louis the Pious, used Abbot Adrevaldus as an envoy to Septimania in 834 and 838, according to the Historia Hludowici imperatoris. However, these dates do not correspond to those given in the abbey's only list, which says that Adrevaldus became abbot in 839 and ruled for three years. Eygilo, the founder of Prüm Abbey, left his own establishment to become abbot of Flavigny in 860. He set up monks at Corbigny, but later left Flavigny when he was appointed Archbishop of Sens. His successor, Geylo, resigned to become abbot of Tournus and was later appointed bishop of Langres.

PROBLEM: Question: Which city had a bigger population in 2013? Passage:Tropical cyclones - known depending on location as cyclones, hurricanes or typhoons - with their precipitation, storm surges and winds are highly destructive and deadly phenomena; the 1900 Galveston hurricane claimed over 8,000 fatalities and was the worst natural disaster in United States history, while Hurricane Katrina in 2005 became the costliest hurricane in United States history with over 80 billion dollars damage and over 1600 fatalities. In other parts of the world, a 1970 cyclone killed 300,000 in Bangladesh; Japan in 2004 was hit by 10 typhoons and in 2005 five separate cyclones hit the Cook Islands in a short timeframe; a year later records were broken by Typhoon Saomai in China and Cyclone Larry in Australia. Finally, in 2013 Typhoon Haiyan became one of the most intense tropical cyclones ever recorded and caused 6,000 fatalities in the Philippines. Further, increased coastal development in general and in the United States rapid population growth along hurricane-prone coasts is creating additional attention to the danger posed by tropical cyclones and the interest in the hazard existing for major cities like Miami and New Orleans. Tropical cyclones can also have positive effects on society, for example by bringing rain to drought-prone regions. Finally, there is increasing evidence that tropical cyclone influence the climate themselves by enhancing poleward heat transport.
