[EX Q]: Question: How old was Adrian "King" Cole the year that headquarters RAAF Station Richmond was formed as a separate entity? Passage 1:The Indian Squads were announced on 13 February. Dhawal Kulkarni got his maiden call up to the national squad, having been selected for the test squad after a strong debut Ranji trophy season where he was the highest wicket taker. L Balaji made a return to the Test squad after a five-year hiatus having last played in a test in 2004. Balaji was dropped from the ODI squad after he played in a single match in the previous tour, he was replaced by the now fit Munaf Patel. In the test squad Balaji replaced Pragyan Ojha with the selectors opting for an extra seamer instead of an extra spinner for the tour. Ojha retained his place in the ODI and T20 squads. Subramaniam Badrinath was dropped from the test squad in favour of reserve Wicket-Keeper Dinesh Karthik after Karthik too had a strong Ranji trophy season. Karthik was selected for all three squads, replacing Jadeja in the ODI squad. Ravindra Jadeja's impressive ODI debut was rewarded with a call up to the Twenty20 squad but Jadeja will be replaced by Sachin Tendulkar for the subsequent ODI series. Munaf Patel made a return to all three squads after having to pull out midway through the previous tour of Sri Lanka due to injury. Harbhajan Singh also made a return to all three squads after having to pull out at the beginning of the previous tour to Sri Lanka due to injury.
 Passage 2:A military flying school was set up at the site of the present-day RAAF base on 28 August 1916, when the area was known as Ham Common. RAAF Station Richmond was established on 30 June 1925 as the fledgling service's first air base outside Victoria. Its initial flying unit was No. 3 (Army Cooperation) Squadron, operating Airco DH.9 light bombers and Royal Aircraft Factory S.E.5 fighters, and for the next decade the commanding officer of No. 3 Squadron was also in charge of the base. Among these were Squadron Leaders Frank Lukis (1925–30), Harry Cobby (1930–31), and Bill Bostock (1931–33). Headquarters RAAF Station Richmond was formed as a separate entity on 20 April 1936, under the command of Group Captain Adrian "King" Cole. Other units, including No. 22 Squadron flying Hawker Demons, and No. 2 Aircraft Depot, had been established in the preceding months. No. 4 (General Reconnaissance) Squadron was formed in May 1937, followed by No. 6 (General Reconnaissance) Squadron in March 1939. Two Fleet Cooperation units were also established, No. 5 Squadron in April 1936 and No. 9 Squadron in January 1939. No. 23 (General Purpose) Squadron formed in February 1939. As well as an Air Force base, in its pre-war days Richmond was used as a supplementary airport for Sydney; various aviation pioneers employed it in the 1930s, including Charles Kingsford Smith and Jean Batten.

[EX Q]: Question: What was the most popular movie the actor who played an Edwardian hunter in the Eternal Summer was in? Passage 1:Arthur Aloysius O'Leary was born on September 27, 1887, in Washington, D.C. His father was a worker on the Baltimore and Ohio Railroad. He was educated at Gonzaga College, and his parish was the adjacent St. Aloysius Church. He entered the Society of Jesus on August 14, 1903, and was sent to St. Andrew-on-Hudson in New York for his scholasticate. He then completed his studies at Woodstock College in Maryland, where he earned a Doctor of Philosophy. He went to Georgetown University in 1912, as a professor of philosophy, holding the position until 1916. At the same time, he was also spiritual director for the university. He was finally ordained a priest in 1919, becoming a member of the first class of priests ordained at Georgetown. He then returned to St. Andrew-on-Hudson, where he taught for several years.
 Passage 2:Vicelinus was called to Bremen to act as teacher and principal of the school, and was offered a canonry by Archbishop Frederick of the Archbishopric of Hamburg-Bremen. In 1122 he may have gone to Laon to complete his studies under Abelard. In 1126, Vicelinus decided to travel to Madgeburg, in order to see St. Norbert, who at that time was the archbishop. He hoped that St. Norbert would ordain him a priest and he could begin missionary work among the Slavs. For one reason or another this plan failed and so Vicelinus returned to Bremen, where Bishop Albero ordained him. Hamburg-Bremen's Archbishop Adalbero sent him among the Polabian Slavs, and in the fall of 1126 Henry, Prince of the Obotrites, gave him a church in Liubice, near the site of the later Lübeck. At the death of Henry (22 March 1127) Vicelinus returned to Bremen, and was appointed pastor at Wippenthorp. This gave him an opportunity to work among the Wagrians and neighbouring Obotrites.
 Passage 3:Chibnall suggested including a "bonkers" gang of characters picked from around time and space. He felt that Doctor Who could have "collisions of characters that no other show in the world can do", and that it was about finding a "disparate" group of characters who would "bounce" off each other. Nefertiti's decision not to return to her own time fits in with the historical record, as the date and cause of her death are unknown. Chibnall asked to introduce Rory's father, as Amy and Rory would be leaving in four episodes and Rory's family life had not been explored yet. Mark Williams who played Rory's father previously appeared in the Fifth Doctor audio adventure The Eternal Summer. Rupert Graves, who played an Edwardian hunter in this episode, previously worked with Moffat on the BBC series Sherlock. David Bradley's character, Solomon, was modelled on a "well-known nightclub owner with long hair". Chibnall described him as "half businessman, half Somali pirate". Bradley and Williams had previously worked together on the Harry Potter film franchise. Bradley was later cast as the First Doctor William Hartnell for the 50th anniversary documentary drama An Adventure in Space and Time. Comedy duo Mitchell and Webb provided the voices of Solomon's two robots; executive producer Caroline Skinner called the casting choice "perfect". Richard Hope, who played the Silurian Bleytal, previously appeared as Malohkeh in the episodes "The Hungry Earth", "Cold Blood" and "The Wedding of River Song".

[EX Q]: Question: How many women were employed at Eton College the year Hamilton left the Coldstream Guards? Passage 1:Hamilton followed his mother as a Christian Scientist, and attended Claremont Fan Court School and then Eton College. He did National Service in the Coldstream Guards from 1955 to 1958. His father had been wounded while serving with the same regiment in the Second World War. Hamilton then worked in the City of London as a gilts broker. He was a member of the London Stock Exchange from 1967 to 1980. He remained in the City for only a short period, leaving when he inherited two estates from his father's cousin. He married his wife, Corinna Dixon, in 1967, and they had four sons together. He succeeded his father as Baron Hamilton of Dalzell in 1990, inheriting land near and properties in the village of Betchworth in Surrey, and a Regency mansion.
 Passage 2:As a backbencher in Ralph Klein's Progressive Conservative caucus, Knight moved a number of government bills. The first was 2003's Electric Utilities Act, which made some changes to the government's deregulation of the province's electricity market. Much of the debate around the bill was about whether the government's deregulation had worked well to date. The bill was passed on a party line vote, with Knight's fellow Progressive Conservatives voting unanimously in favour and the opposition Liberals and New Democrats voting unanimously against. Knight also sponsored the Securities Amendment Acts, separate bills with the same name from different years, 2005 and 2006. The first of these was designed to harmonize the securities regulation with that of other provinces. It was supported by Liberals Rick Miller and Bill Bonko, who considered it a step in the right direction. New Democrats gave it a mixed reception, with Ray Martin agreeing that it did make some improvements, but with his colleague David Eggen trying to kill it on third reading, saying that what was needed was a supra-provincial securities regulator. The 2006 edition of the Securities Amendment Act implemented further harmonization, and passed with little debate. The Securities Transfer Act of the same year consolidated and harmonized the province's rules for transferring securities, and passed with all-party support.
 Passage 3:On January 13, UFC revealed this event was originally intended to take place at Arena da Baixada (a much larger venue) in Curitiba, Brazil, and feature a UFC Heavyweight Championship rematch between champion Fabrício Werdum and former two-time champion Cain Velasquez, with former UFC Middleweight Champion Anderson Silva in the co-main event slot, possibly against Michael Bisping. Due to a series of injuries, the company moved the heavyweight bout to a separate event scheduled for February 6, which at that time was . This change made the March 5 event a smaller draw, which led to the transition to the smaller venue in Rio de Janeiro. To maintain local interest, the company then considered booking the main event as a rematch between two Brazilian fighters, Silva and former UFC Light Heavyweight Champion Vitor Belfort. Belfort declined the bout, as he wished to wait for the result of the middleweight title fight at UFC 194. This final fall-through is what prompted the cancellation of the event in Brazil and relocation to Las Vegas. On January 27, it was revealed the Werdum-Velasquez bout (which had been moved to "UFC 196" scheduled for February 6, 2016) was cancelled entirely. This forced that event to alter into a "UFC Fight Night" card, and the originally scheduled "UFC 197" event was renamed UFC 196.
