[EX Q]: Question: What age was Canut VI the year he led a Danish expedition that destroyed Groswin burgh? Passage 1:2007 winner Alberto Contador won the race by a margin of 4′11″, having won both a mountain and time trial stage. His team also took the team classification. and supplied the initial third-place finisher, Lance Armstrong. Armstrong's achievement was later voided by the UCI in October 2012 following his non-dispute of a doping accusation by USADA, and fourth place Bradley Wiggins was promoted to the podium. Andy Schleck, second overall, won the young riders' competition as he had the previous year. Franco Pellizotti originally won the polka dot jersey as the King of the Mountains, but had that result (along with all his 2009 results) stripped by the Court of Arbitration for Sport in 2011 due to his irregular values in the UCI's biological passport program detected in May 2010. and the King of the Mountains title was retroactively awarded to Egoi Martínez. Mark Cavendish won six stages, including the final stage on the Champs-Élysées, but was beaten in the points classification by Thor Hushovd, who consequently won the green jersey.
 Passage 2:Yeo was born in Southampton, England on 7 October 1782 to a naval victualling agent. Yeo was sent to an academy near Winchester for his formal education. Yeo joined the Royal Navy as a midshipman aboard at the age of 10, thanks to his patron, Admiral Phillips Crosby. In 1796, he was made acting-lieutenant and placed in command of the 16-gun sloop . He was made lieutenant permanently on 20 February 1797. The vessel was deployed to the West Indies, where Yeo contracted Yellow fever was ordered home to England to convalesce in 1798. By 1802, Yeo was first lieutenant aboard in the Adriatic Sea. He distinguished himself during the siege of Cesenatico in 1800, when thirteen merchant vessels were burned or sunk. Following the Peace of Amiens in 1802, Yeo was demoted to half-pay.
 Passage 3:Groswin took over the position of nearby Altes Lager Menzlin as a trade center after its decline in the 9th century. The tribal affiliation of the inhabitants, though associated with the greater tribe of the Veleti, is uncertain - while the Ukrani are reported to have dwelled south of the Zarow and the Rani north of the Ryck river, the name of the medieval inhabitants of the area between these rivers is not reported. The lands of Groswin became a castellany of the Duchy of Pomerania during the westward expansion of Wartislaw I in the 1120s, and became part of the Bishopric of Cammin in 1140. In 1153, Stolpe Abbey was founded in the Groswin castellany as the first Pomeranian monastery. A market at the Groswin burgh is documented in 1159. In 1185, a Danish expedition led by Canut VI destroyed the burgh and devastated the castellany. Though the name Groswin stayed in use to refer to the area, the position of the former burgh as the areas center was taken over by nearby Anklam.

[EX Q]: Question: Where was Thomas Kenan's great grandfather born? Passage 1:In 1968, Texas head coach Darrell Royal and his offensive coordinator Emory Bellard introduced what would become known as the wishbone offense. The wishbone was derived from the Split-T offense run at Oklahoma under Bud Wilkinson. In the formation, the quarterback lines up with a fullback and two tailbacks behind him, and on any play may keep the ball, hand off to the fullback, or pitch to a tailback. From the time Bryant arrived at Alabama through the 1970 season, the Crimson Tide ran a pro-style offense. By 1969, Bryant began to recruit larger linemen and tailbacks, and after a pair of six win seasons in 1969 and 1970, Bryant saw the success of the wishbone for the Longhorns and decided to implement the offense for the 1971 season. In spring 1971, Alabama assistants Mal Moore and Jimmy Sharpe traveled to Austin where they saw first hand how the wishbone operated during Texas' final week of spring practice.
 Passage 2:A second battalion was raised in 1804 to increase the strength of the regiment. The 1st battalion embarked for Copenhagen in July 1807 and saw action at the Battle of Copenhagen in August 1807 during the Gunboat War before returning home in November 1807. It then embarked for Portugal in May 1808 for service under General Sir Arthur Wellesley in the Peninsular War and saw action at the Battle of Roliça in August 1808 and the Battle of Vimeiro later that month. In January 1809 the battalion took part in the Battle of Corunna, carrying out successive bayonet charges to keep the French at bay to which General Sir John Moore shouted "Well done, 50th! Well done, my Majors!". The battalion was subsequently evacuated from the Peninsula. Both battalions then embarked from the Downs in July 1809 and saw action in the disastrous Walcheren Campaign. It was the last regiment to leave Holland in December 1809.
 Passage 3:Thomas Stephen Kenan (February 12, 1838 – December 23, 1911) was a Confederate soldier, and later a politician. His parents were Sarah Rebecca Graham and Owen Rand Kenan; he was the grandson of U.S. Congressman Thomas Kenan and great-grandson of Revolutionary War general James Kenan. He started his education in Duplin County, North Carolina at Old Grove Academy in Kenansville (the town was named for his great-grandfather in 1818). Later he spent a year at Central Military Institute in Selma, Alabama. Thomas spent his freshman year of college at Wake Forest in June. Thomas then transferred his sophomore year to the University of North Carolina, where he would graduate in 1857. He studied law for two years with Judge Pearson at Richmond Hill where he practiced law in Kenansville. After graduation and during the Civil War he became Captain of the Duplin Rifles in the Confederate States Army, elected lieutenant colonel of the 43rd North Carolina Infantry Regiment in April 1862, and was promoted to colonel later that year. He was wounded at the Battle of Gettysburg. While on an ambulance train, he and his older brother James Kenan were both captured; they were then imprisoned on Johnson's Island, Ohio. On March 22, 1865, he was released on parole but never switched sides during the war. On his return home he was elected to the state legislature from 1865 to 1867. Later that year he ran for Congress and lost. Not letting that defeat end his political career, he moved to Wilson, North Carolina, where he became mayor and was elected North Carolina Attorney General, serving from 1877 to 1885. In May 1868 he married Miss Sallie Dortch, but they had no children; Sallie died in 1916.

[EX Q]: Question: How many years did the Great Depression last? Passage 1:M48s were also used with mixed results during the Six-Day War of 1967. On the Sinai battlefront, Israeli M48s upgunned with the then-advanced 105 mm L7 rifled tank gun were used with considerable success against Egyptian IS-3s, T-54s/T-55s, T-34/85s and SU-100s supplied by the Soviet Union during the 1950s and the 1960s (such as during the Second Battle of Abu-Ageila. However, on the West Bank war-front, Jordanian M48s (Jordan was also a user of the M48 Patton as was Israel at the same time-period) were often defeated by Israeli 105mm-armed Centurions and WWII-era upgraded M4 Shermans (M-51s upgunned with French-built 105 mm tank guns (not to be confused with the British L7 105mm tank gun)). In purely-technical terms, the Pattons were far superior to the much-older Shermans, with shots at more than 1,000 meters simply glancing off the M48's armor. However, the 105 mm main gun of the Israeli Shermans fired a HEAT round designed to defeat the Soviet T-62 tank, which was the USSR's response to the M48's successor in US service, the M60 Patton. The Jordanian Pattons' general failure on the West Bank could also be attributed to excellent Israeli air superiority. The Israeli Army captured about 100 Jordanian M48 and M48A1 tanks and pressed them into service in their own units after the war, as the same as were the Jordanian M113 APCs they seized during the war.
 Passage 2:On the song "The Kid Frankie", Khalifa raps over the English R&B band Loose Ends' No. 1 hit single, "Hangin' on a String" (1985). Khalifa stated that the song was inspired by the character Frankie from the film The Business (2005), who listens to Loose Ends while traveling around Spain. The song "Never Been" samples "Schala's Theme" from the soundtrack to the video game Chrono Trigger with its soundtrack composed by Yasunori Mitsuda. The song "Up", samples Tevin Campbell's "Could It Be". "In the Cut" samples "Let Go" by Frou Frou from the end credits of the film Garden State, the song "We're Done" samples the single "Our Time Is Here" by Demi Lovato from the Disney soundtrack Camp Rock. The song "Visions" contains a sample from "Huit Octobre 1971" by Cortex. "Spotlight" sampled "Theme from the Planets" by Dexter Wansel, from his album "Life on Mars" (1976) and "Still Blazin" samples Alborosie's song of the same name.
 Passage 3:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.
