Question: How many members did No. 11 Group have during the years of the Blitz? Passage 1:As a result of Hull finishing in fourth place in the Championship they qualified for the Football League play-offs. In the play-off semi finals Hull played against fifth placed team Derby County over two legs. The first leg was held on 14 May 2016 at Derby's Pride Park. Hull's top scorer Abel Hernández was the first to score with a strike from 25 yards after half an hour. This was followed 10 minutes later with a shot by Moses Odubajo deflected in by defender Jason Shackell. Andrew Robertson completed the scoring with a late stoppage time goal to give Hull a 3–0 advantage going into the second leg at the KC Stadium on 17 May 2016. Derby got off to a great start with a goal from close range by Johnny Russell after 7 minutes. Their lead was doubled when a sliced ball by Andrew Robertson went into his own net 30 minutes later. Derby continued to press but Hull hung on to deny them any further scores. The match ended 2–0 to Derby, but Hull progressed 3–2 on aggregate, much to the relief of manager Steve Bruce who was in charge for the 200th time. The final, on 28 May 2016 at Wembley Stadium, was a local derby against Sheffield Wednesday who beat Brighton & Hove Albion 3–1 on aggregate in the other semi-final. Hull beat Sheffield Wednesday 1–0 in the final with the only goal coming from a 25-yard wonder strike by Mohamed Diamé in the 72nd minute. The Tigers made an immediate return to the top flight and it was Bruce's fourth promotion to the Premier League as manager.
 Passage 2:Duli Pengiran Muda Mahkota Football Club (His Royal Highness the Crown Prince of Brunei Football Club in English, commonly known as DPMM FC) is a professional football club based in Bandar Seri Begawan, Brunei. The club played in the Brunei Premier League in the early 2000s, winning the league title in 2002 and 2004. The club then decided to play in Malaysia, and joined the Malaysian Premier League as a foreign-based team in for the 2005–06 season. They won promotion to the Malaysian Super League (the top tier of Malaysian football) at the end of their first season in Malaysian football, and then finished 3rd and 10th in the following two season in the Super League. The club then left the Malaysian league and joined Singapore's Singapore Premier League for the 2009 season. They won the Singapore League Cup, but were then forced to withdraw from the league competition five games before the end of the season after FIFA suspended the Football Association of Brunei Darussalam for government interference in its affairs, thus barring teams from Brunei from taking part in overseas competitions. All the club's league results for 2009 were therefore expunged. At the end of the suspension, they re-entered the S.League and won the title in 2015, just after a near-miss in 2014.
 Passage 3: the Second World War, the station was very active during the Battle of Britain and the Blitz in 1940–41 in No. 12 Group (controlled from RAF Watnall in Nottingham) as it was the main fighter station for a lot of the southern East Midlands, and fighters from the station would often patrol as far as Birmingham. During the Battle of Britain many squadrons were rotated through Wittering to spells in the south of England with No. 11 Group that was bearing the brunt of the battle. With many of the Luftwaffe raids during the Blitz taking part at night, Wittering-based squadrons were instrumental in the development of night combat techniques. These included the use of the Turbinlite aircraft which replaced the nose with a powerful searchlight insulated in the nose of Havocs and Bostons. In April 1943 No. 141 Squadron were moved in, operating de Havilland Mosquitoes. 1943 also saw the station host 2 USAAF squadrons, albeit temporarily: 63 Fighter Squadron USAAF with its P47s operated from Wittering between January and March before moving to RAF Horsham St Faith; 55 Fighter Squadron operated its P38s and P51s from Wittering between August and March 1944 before moving to nearby RAF Kingscliffe.

 Passage 2:The film begins with a narrated map showing the Confederate Army of Northern Virginia, commanded by Robert E. Lee, crossing the Potomac River to invade the North in June 1863, marching across Maryland and into Pennsylvania. On June 30, Confederate spy Henry Thomas Harrison reports to Lt. Gen. James Longstreet, commander of the First Corps, that the Union Army of the Potomac is moving in their direction, and that Union commander Joseph Hooker has been replaced by George Meade. Longstreet reports the information to General Lee, who is concerned that the army is moving "on the word of an actor", as opposed to that of his cavalry chief, J. E. B. Stuart. Nonetheless, Lee orders the army to concentrate near the town of Gettysburg. At the Union encampments near Union Mills, Maryland, Col. Joshua Lawrence Chamberlain of the 20th Maine is ordered to take in 120 men from the disbanded 2nd Maine who had resigned in protest, with permission to shoot any man who refuses to fight. Chamberlain speaks to the men, and is able to persuade all but six to take up arms.

Question: Who won the season of X factor that Cowell was a judge with newcomer Rita Ora? Passage 1:Hart began his architectural career in Denver, finding work in 1898 as a draftsman for the firm of Willis A. Marean and Albert J. Norton, who later designed the Colorado Governor's Mansion (1908). In 1900, he joined Frank E. Edbrooke & Company, who had designed the Brown Palace Hotel (1892). By 1902, he had moved to California, where he spent a year drafting plans for new campus building of Stanford University, where conservative Richardsonian Romanesque detail adorned newly evolving California Mission Revival Style architecture under the guidance of Boston-based Shepley, Rutan & Coolidge. At Stanford, he was also exposed to the landscape architecture of Frederick Law Olmsted. He then spent a year working for the young firm of Meyer and O'Brien before joining the firm of Bliss and Faville just in time to work on their most famous project, the St. Francis Hotel, and other major buildings arising from the ashes of the San Francisco earthquake of 1906, including the Neoclassical architecture of the Bank of California and the more Beaux-Arts style of the Union Savings Bank (1909), the Columbia (now Geary) Theater (1909), and the Masonic Temple (1912).
 Passage 2:In the United States, geologic maps are usually superimposed over a topographic map (and at times over other base maps) with the addition of a color mask with letter symbols to represent the kind of geologic unit. The color mask denotes the exposure of the immediate bedrock, even if obscured by soil or other cover. Each area of color denotes a geologic unit or particular rock formation (as more information is gathered new geologic units may be defined). However, in areas where the bedrock is overlain by a significantly thick unconsolidated burden of till, terrace sediments, loess deposits, or other important feature, these are shown instead. Stratigraphic contour lines, fault lines, strike and dip symbols, are represented with various symbols as indicated by the map key. Whereas topographic maps are produced by the United States Geological Survey in conjunction with the states, geologic maps are usually produced by the individual states. There are almost no geologic map resources for some states, while a few states, such as Kentucky and Georgia, are extensively mapped geologically.
 Passage 3:In October 2013, it was reported that Cowell may return to the UK version of The X Factor for series 11 in the place of Gary Barlow, and on 7 February 2014, his return was officially confirmed. This resulted in the cancellation of the US version after three seasons by Fox. He joined judges Louis Walsh, Cheryl Fernandez-Versini, and new judge, former Spice Girls member Mel B, who replaced Nicole Scherzinger. For his eighth series, he was given the Over 25s category. On 13 December, Ben Haenow and Fleur East reached the final two, which meant that Cowell was the winning mentor for the first time since series 3 in 2006, when he had both Leona Lewis and Ray Quinn in the final. Haenow became the eleventh winner on 14 December. In March 2015, it was announced that Cowell would return to the X Factor for its twelfth series along with veteran judge Cheryl Fernandez-Versini, and newcomers Rita Ora and BBC Radio 1 DJ Nick Grimshaw.
