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.

In 1422 and again in 1429 he was sent by Emperor John VIII Palaiologos as an envoy to the Ottoman Sultan Murad II. At the time he had the relatively lowly rank of protovestiarites, but was quickly promoted to protostrator and then to the senior rank of megas stratopedarches, which he held already during his mission in 1430 to Pope Martin V. During his return from the mission to the Pope, on orders from the Emperor, he raised Thomas Palaiologos to the rank of Despot in the Morea.

[EX Q]: Question: Was Oslo's police chief born in the city he protects? Passage 1:Reg Keys was an ambulance paramedic for 19 years in Solihull before retiring to Llanuwchllyn, Bala in North Wales. In the 2005 UK general election, he stood against the then Prime Minister, Tony Blair, in the Sedgefield constituency. Keys declared at the outset of the campaign that he had been a Labour Party voter and was still basically socialist, but that he was seeking election as a candidate opposed to Blair's policy on the Iraq War. He claimed that by electing him, voters could keep the Labour Party in power but with Gordon Brown as the likely Prime Minister rather than Blair. Former Independent MP Martin Bell urged the other parties to withdraw their candidates as removing a supporter of the war from office would send a message to President Bush and other World Leaders who had supported him. During the campaign, UK newspaper The Guardian's Stuart Jeffries asked Keys, "Is it difficult to be a political candidate in these circumstances, when you are still clearly grieving?", to which he replied "Yes it is. […] I feel, though, that I have a responsibility to Tom. I keep going back to the words of a widow of a man who died on the Kursk […]. She said: 'If you betray your country you are a traitor and you will go to prison. But if your country betrays you, what can you do?' I think I have an answer to that: we can use our vote to get rid of those people who betrayed my son and other men like him. That's what I want the people of Sedgefield to do."
 Passage 2:Meanwhile, at Oscarsborg Fortress near Drøbak, Colonel Birger Eriksen prepares his undermanned and inexperienced garrison for combat, while receiving reports from the outlying fortresses of incoming German ships. Early on the morning of 9 April, Eriksen spots the German cruiser Blücher entering Drøbak Sound. Despite having received no instructions from Oslo to engage, Eriksen considers the German ship to be hostile and gives the order to fire, and the fortress's guns and torpedo battery sink the Blücher. Prime Minister Nygaardsvold telephones the King, informing him of the impending invasion, and advises him to flee Oslo. The Royal Family boards a train for Hamar, where the Norwegian Parliament convenes to discuss negotiations with Germany. Bräuer meets Oslo's police chief Kristian Welhaven, his intermediary with the Norwegian Cabinet, to reassure them of his desire to negotiate; at the same time, Pohlman receives orders from Berlin to send paratroopers to Hamar to capture the King and the Cabinet. Nasjonal Samling leader Vidkun Quisling proclaims himself Prime Minister over the national radio, and calls upon the Norwegian people to accept the German occupation forces. Bräuer receives instructions from Hitler himself to go directly to the King and convince him to recognise Quisling's government, though Bräuer is convinced that neither Haakon nor the Cabinet will accept this.
 Passage 3:Apart from major religious and national holidays, the bell was rung on some of the most significant moments in the history of Poland, including the German invasion of Poland on 1 September 1939, on the eve of Poland's entry into the European Union on 30 April 2004, on the occasion of each visit by Pope John Paul II, and after the plane crash which killed President Lech Kaczyński and dozens of other high-ranking officials on 10 April 2010. It also tolled during funerals or reburials of several great Poles, such as Adam Mickiewicz (1900), Marshal Józef Piłsudski (1935), General Władysław Sikorski (1993), Pope John Paul II (2005), and Lech Kaczyński with his wife (2010). It rung defiantly on Polish national holidays in the times of partitions (1795–1918) and under the communist regime (1945–1989), thus reinforcing its role as a national symbol
