[EX Q]: Question: How long had the London Stock Exchange been in existence for by the year Hamilton quit his membership there? 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.

[EX Q]: Question: Was Forbes or the Guardian founded first? Passage 1:"The Lazy Song" has received generally mixed reviews from contemporary music critics. Eric Henderson of Slant Magazine noted that in song Mars "paints a portrait of Al Bundy as a young man" and Andy Gill of The Independent classified the song as a "laidback acoustic groove". Tim Sendra of AllMusic said it was one of the tracks from Doo-Wops & Hooligans that captured the laid-back groove. Scott Mervis of the Pittsburgh Post-Gazette described the song as a "Jason Mraz/Sugar Ray-style reggae." Sean Fennessey, a reviewer of The Washington Post, felt the song was written in a "quality that is both endearing and damning". A mixed review came from Digital Spy reviewer Lewis Corner, who commented that the song is a "summery ditty more head-boppable than a Churchill nodding dog, which, given his current state of mind, is probably about all he could muster", giving it three stars out of five. and from Blues & Soul magazine who called it "reggae tinged" and found it to be "somewhat of a filler but for the likes of Peter Andre" is great. Entertainment Weeklys Leah Greenblatt considered that "other modes suit him less well; The Lazy Song is perhaps better left to Jason Mraz". Alexis Petridis of The Guardian, gave the song a negative review, writing that "The Lazy Song" "gets no further than the second verse before Mars – nothing if not keen to keep his fans abreast of his every activity in a world of 360-degree connectivity – announces that he's planning on having a wank". Nick Messitte writing for Forbes criticized the single for copying the "happy-go-lucky meanderings of Jason Mraz's "I'm Yours", but also using the same pattern as Travie McCoy and Mars' "Billionaire" (2011).
 Passage 2:At a meeting between the council of Zaporozhian Cossacks and Vasiliy Buturlin, representative of Tsar Alexey I of the Tsardom of Russia, during the Khmelnytsky Uprising. The "Pereyaslav Council" (Pereyaslavs'ka Rada in Ukrainian) of Ukrainians took place on January 18; it was meant to act as the supreme Cossack council and demonstrate the unity and determination of the "Rus' nation". Military leaders and representatives of regiments, nobles and townspeople listened to the speech by the Cossack hetman Bohdan Khmelnytsky, who expounded the necessity of seeking the Russian protection. The audience responded with applause and consent. The treaty, initiated with Buturlin later on the same day, invoked only protection of the Cossack state by the Tsar and was intended as an act of official separation of Ukraine from the Polish–Lithuanian Commonwealth (Ukrainian independence had been informally declared earlier in the course of the Uprising by Khmelnytsky). Participants in the preparation of the treaty at Pereyaslav included, besides Khmelnytsky, Chief Scribe Ivan Vyhovsky and numerous other Cossack elders, as well as a large visiting contingent from Russia.
 Passage 3:In 1760 the French zoologist Mathurin Jacques Brisson included a description of the purple-throated sunbird in his Ornithologie based on a specimen collected in the Philippines. He used the French name Le grimpereau pourpré des Philippines and the Latin Certhia Philippensis Purpurea. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the purple-throated sunbird. Linnaeus included a brief description, coined the binomial name Certhia sperata and cited Brisson's work. Linnaeus specified the type location as the Philippines but this was subsequently restricted to Manila. The specific name sperata is Latin for "bride" or "betrothed". The species is now placed in the genus Leptocoma that was introduced by the German ornithologist Jean Cabanis in 1850.

[EX Q]: Question: Who commanded the 32nd Virginia Volunteer Infantry Regiment when Goggin joined the Confederacy? Passage 1:In 1861, Goggin moved back to Virginia, entering the Confederate States Army on July 1, 1861 as a major in the 32nd Virginia Volunteer Infantry Regiment where he was assigned to lead a battalion. Goggin and the 32nd Virginia Infantry served under Maj. Gen. John B. Magruder in 1861 and into 1862 during the Peninsula Campaign. Goggin joined the First Corps, Army of Northern Virginia in April 1862, serving on the staff of Maj. Gen. Lafayette McLaws as his assistant adjutant general. He served in this capacity during all of the First Corps' engagements, in both the Army of Northern Virginia and the Army of Tennessee, until the spring of 1864. During the Battle of Fort Sanders in November 1863, Goggin carried a message from McLaws to Lt. Gen. James Longstreet, informing him that the attack was beginning to fail and it was futile to carry in on. When McLaws was replaced with Maj. Gen. Joseph B. Kershaw in May 1864, Goggin served as his assistant adjutant general as well. His service in this post was highly praised by Goggin's superiors.

 Passage 3:Lake Minchin was a saltwater lake, which covered the basins of the Salar de Uyuni, Salar de Coipasa, Lake Poopo and Salar de Empexa, including the towns of Llica, Oruro and the Desaguadero River valley. The lake had an extension of in east-west direction and of in north-south direction. A sill at Ulloma separated Lake Minchin from Lake Titicaca. Water levels reached an altitude of above sea level, indicating a depth of above the Uyuni basin. In the Poopo basin, water levels may have reached . At Cerro Lipillipi terraces between are dated between 25,700 and 31,750 BP. Another estimate is . Earlier estimates of the altitude are , resulting in depths of . Such water heights exceed these of preceding lakes, and together with even higher water levels of the subsequent Lake Tauca they are part of a trend of increasing water levels in the southern Altiplano which contrasts with progressively decreasing lake levels in the northern Altiplano. Earlier research suggested an opposite trend of lowering water levels in both basins. The surface area of Lake Minchin may have been , or . A lake terrace at is also attributed to Lake Minchin. The highest lake terraces at and were later found to belong to Lake Tauca, making it the deeper of the two lakes. If Minchin reached a water level of it may have spilled into the Pilcomayo River, draining from there via the Rio de la Plata into the Atlantic Ocean. It is also possible that the lake temporarily drained into the Pacific Ocean through its southwesternmost sector at Salar de Ascotán; such an outlet would have existed for only a brief time, however, before it was obstructed by volcanism. San Agustin, San Cristobal and Colcha formed islands in the lake, which was separated into a Coipasa half and an Uyuni half by a peninsula of the Serranía Intersalar; straits at Llica and Salinas de Garci Mendoza connected the two halves. Bays developed close to Isluga, Empexa and Ollagüe.
