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.

 Passage 2:Route 67 is mostly a two-lane surface road, with a divided four-lane section in Southbury. It begins in New Milford as a 0.5 mile concurrency with US 202 as the latter leaves a concurrency with US 7. After crossing the Housatonic River into the center of town, Route 67 breaks away to the southeast. In Bridgewater, it meets the northern end of Route 133. In Roxbury, it meets the southern end of Route 199 and the western end of Route 317. It then clips a corner of Woodbury before passing into New Haven County and the town of Southbury, where it passes the northern end of Route 172 before joining US 6 for a 4 lane divided 1.6 mile concurrency leading to a junction with I-84 at Exit 15. Here, US 6 joins I-84 West and Route 67 continues to the southeast becoming a 2-lane road once again. After intersecting Route 188, it enters Oxford, where it has a junction with the west end of Route 42. In Seymour, it passes the western end of Route 313 before crossing the Naugatuck River. On the east shore of the river, it meets the Route 8 expressway at Exits 21 & 22. It then passes the northern end of Route 115 before heading into Woodbridge, where Route 67 ends at Route 63. 
 Passage 3:Arsenal had finished the previous season as runners-up in the Premier League, overhauled by Manchester United in the final ten weeks of the season. The club did, however, retain the FA Cup, with a 1–0 win against Southampton. Such was Arsenal's effective start to the 2002–03 campaign, manager Arsène Wenger suggested his team could remain the whole season undefeated in all competitions:It's not impossible as A.C. Milan once did it but I can't see why it's so shocking to say it. Do you think Manchester United, Liverpool or Chelsea don't dream that as well? They're exactly the same. They just don't say it because they're scared to look ridiculous, but nobody is ridiculous in this job as we know anything can happen. The team lost to Everton a month after Wenger's proclamation; teenager Wayne Rooney scored the match winner, which ended a run of 30 league games without defeat. By February 2003, Arsenal moved five points clear of Manchester United at the top of the league table, but injuries to key players, not least captain Patrick Vieira, had destabilised the team. Draws in April, coupled with a defeat to Leeds United at home, mathematically ended Arsenal's chances of retaining the title. Wenger refuted opinions from the media that their season was a failure and said:

Question: Which railway company that had control of the Carluke railway station is the oldest? Passage 1:The first station to be named Carluke was a separate station near Bogside Farm, originally opened as Stirling Road station in 1845 by the Wishaw and Coltness Railway. The current station opened as part of the Caledonian Railway Main Line extension from Beattock on 15 February 1848. It was rebuilt by the Caledonian Railway around the start of the 20th century. It passed to the control of the London, Midland and Scottish Railway (LMS) upon its formation on 1 January 1923 under the terms of the Railways Act 1921 until the nationalisation of the "Big Four" on 1 January 1948 and the resultant creation of British Railways. Thereafter, control of the station, in common with all of those on the WCML north of Gretna, became the responsibility of BR's Scottish Region until the formation of the Greater Glasgow Passenger Transport Executive (GGPTE) on 1 June 1973. Under the terms of the Transport Act 1968, the specification of timetables, fares and quality standards for all rail services within the erstwhile Strathclyde region became the responsibility of the PTE, with trains and stations receiving their distinctive corporate colour scheme from 1985. However, in November 2005, these powers were transferred to the Scottish Executive and were subsequently passed to Transport Scotland upon its creation on 1 January 2006. Consequently, both the station and the rail services which call thereat are today operated by ScotRail.
 Passage 2:Hurling is administered by the Gaelic Athletic Association (GAA). It is played throughout the world, and is popular among members of the Irish diaspora in North America, Europe, Australia, New Zealand, South Africa, Argentina, and South Korea. In many parts of Ireland, however, hurling is a fixture of life. It has featured regularly in art forms such as film, music and literature. The final of the All-Ireland Senior Hurling Championship was listed in second place by CNN in its "10 sporting events you have to see live", after the Olympic Games and ahead of both the FIFA World Cup and UEFA European Football Championship. After covering the 1959 All-Ireland Senior Hurling Championship Final between Kilkenny and Waterford for BBC Television, English commentator Kenneth Wolstenholme was moved to describe hurling as his second favourite sport in the world after his first love, football. Alex Ferguson used footage of an All-Ireland Senior Hurling Championship final in an attempt to motivate his players during his time as manager of Premier League soccer outfit Manchester United; the players winced at the standard of physicality and intensity in which the hurlers were engaged. In 2007, Forbes magazine described the media attention and population multiplication of Thurles town ahead of one of the game's annual provincial hurling finals as being "the rough equivalent of 30 million Americans watching a regional lacrosse game".
 Passage 3:McGillivray returned to Montreal in 1793 and then took a trip to Scotland and England. He was now a partner in McTavish, Frobisher & Co., who controlled the NWC. With John Gregory, he was sent to manage the company's huge depot at Grand Portage, stirring jealousy among some of the other partners. When Joseph Frobisher retired in 1798, McGillivray took his place. He set up an agency at New York City to get around the East India Company's monopoly enabling them to trade with China. He was closely involved too with the firm of McTavish, Fraser & Co., at London, managed by another relation of his uncle's, John Fraser. In 1803, he helped organize the move of the NWC's main depot from Grand Portage to Thunder Bay. All this time he was dealing with relations with the Hudson's Bay Company and the splinter XY Company that had broken away from the NWC, led by John Richardson.
