 Passage 2:Following his completion of secondary school, Demiéville spent time studying in Munich, London, and Edinburgh, where he was able to attend lectures by George Saintsbury at the University of Edinburgh. He then attended the University of Paris, where he wrote an essay on the musical suite of the 17th and 18th centuries and was awarded a licentiate degree in 1914. Demiéville then spent the year 1915 studying at King's College London where he was introduced to Chinese, which quickly became his focus. After returning to France, Demiéville studied at the École des Langues Orientales Vivantes (School of Living Oriental Languages), after which he moved to the Collège de France, where he further studied Chinese under the tutelage of Édouard Chavannes and began learning Sanskrit from Sylvain Lévi.

 Passage 3:At the time of his ordeal, Berk was the regional dean of the Texas Tech medical branch in Amarillo, but on August 1, 2006, he was moved to the high position at the Lubbock campus. There are two other branch campuses in Odessa and El Paso. At the time of his abduction, Berk was at home on Sunday morning with his younger son, Justin. The older son, Jeremy, was away in college. Berk's wife, Shirley H. Berk (born c. 1950), a microbiologist who had served on a school board while they lived in Johnson City, Tennessee, was at church. The culprit, Jack Lindsey Jordan (born in 1963 in Seminole, Texas), gained entry from an open rear garage door and an unlocked back entrance to the residence. Normally, both the garage and the back door would have been locked. Jordan demanded money and jewelry to pay for transportation and narcotics, particularly methamphetamines, as he proceeded along Interstate 40 west toward New Mexico. After being held for four hours in Jordan's vehicle on a cool, windy day, common to the Panhandle in March, Berk was released unharmed near a gasoline station in rural Bushland in southwestern Potter County. This life-threatening event propelled the physician to write about his ordeal. He interlaces the narrative with much of his life story, from his birth in New York City, his childhood in New Jersey, his medical education at Boston University School of Medicine, his work in the fields of infectious diseases,geriatrics, and internal medicine at the East Tennessee State University James H. Quillen College of Medicine in Johnson City, and his relocation to Amarillo, his adopted city which he had grown to love. Since the events of 2005, Dr. Berk has been transferred to the main medical campus in Lubbock.

Question: Which of the World Cup stars that played in the WUSA is the youngest? Passage 1:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828–832, briefly in 841 and again under Caliph al-Wathiq (r. 842–845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.
 Passage 2:The team began the 1888 season with part-time outfielder, Dave Rowe, as their player-manager. On April 18, they suffered a 10–3 loss to Tony Mullane and the Cincinnati Reds in their first game, however, they collected their first win the next day. Although they had a win–loss record of 43–89 in their initial season, finishing last out of the league's eight teams, and went through two managerial changes, there were a couple of bright moments; on June 6, Henry Porter threw a no-hitter, and on June 13, Sam Barkley hit for the cycle. The franchise's only future Hall of Fame player, "Slidin'" Billy Hamilton, began his career as a part-time outfielder in 1888, and was their starting right fielder in 1889. Bill Watkins, who had finished the 1888 season as the team's manager, stayed in that role for the full 1889 season, and guided them to an improved win–loss record of 55–82, with two ties, finishing seventh among the league's eight teams.
 Passage 3:The first women's professional soccer league in the U.S. formed after the success of the 1999 Women's World Cup. The Women's United Soccer Association (WUSA) ran from 2001–2003 and featured many of the World Cup stars, including Mia Hamm, Michelle Akers and Brandi Chastain. Its successor Women's Professional Soccer (WPS) ran from 2009–2012. Currently, the National Women's Soccer League (NWSL) is the top professional league in the country and was formed in 2012. The NWSL season runs from spring to early fall (typically April – October). In 2017, A&E Networks bought an equity stake in the league and broadcasts a game of the week on Lifetime, and formerly streamed all games online via the go90 platform. During the 2018 season, the NWSL moved some of the games originally scheduled to air on Lifetime to evening slots on ESPNews (both channels being part of the Disney family), and when go90 owner Verizon shut down that platform at the end of July, the NWSL streamed the games that were intended for go90 on its own website.

 Passage 2:According to the United States Census 2013 estimate, the combined statistical area has a population of 1,313,105. It is the 42nd largest population sub-region in the United States, and the largest population region in Alabama, constituting roughly 1/4 of the state's population. It is the largest population region in Central Alabama. The northern counties of the metropolitan area overlap North Alabama known locally as the "Tennessee Valley" making it the largest metropolitan area in that region as well. Nearby counties Tuscaloosa, Etowah, and Calhoun, while not officially a part of Greater Birmingham, contribute significantly to the region's economy. The Birmingham media market covers these counties as well. Birmingham is part of the Piedmont Atlantic Megaregion containing an estimated 19 million people, while many residents also consider themselves part of the Deep South. It is classified as Southeast by the U.S. Census and also falls in the geographic area of the Upland South due to its location at the southern terminus of the Appalachian foothills. The entire MSA and CSA are within the congressional Appalachian Regional Commission's definition of Appalachia.
 Passage 3:After the deposition of the Saxon duke Henry the Lion in 1180, the Regenstein counts were temporarily arrested by the forces of Emperor Frederick Barbarossa, but were reconciled with the Hohenstaufen monarch soon after. After a lengthy feud Heimburg Castle, built about 1170 by King Henry IV and soon after devastated during the Saxon Rebellion, was acquired by the Regenstein counts in the early 14th century. The Regenstein-Heimburg branch re-united the Regenstein and Blankenburg estates in 1343, under the rule of the most renowned Count Albert II (1310–49), who since the 1330s was frequently in dispute with the leaders of the surrounding estates like the Halberstadt bishops and the Abbesses of Quedlinburg; he was finally assassinated by the henchmen of Bishop Albert II of Halberstadt. These tales were romanticised in the ballad The Robber Count () by Gottfried August Bürger, melodized by Johann Philipp Kirnberger and the novel of the same name by Julius Wolff.
