Question: How long did Aulus Plautius live after capturing the lands south of the River Trent? Passage 1:The general outline of the Roman conquest of Britain during the 1st century AD is recorded by historical sources; for the involvement of specific forts historians depend on archaeological excavations. This part of Britain was occupied by a tribe known as the Cornovii. In AD 46–47 the Roman Army led by governor Aulus Plautius had probably occupied the lands to the south of the River Trent. Late in 47 the new governor of Britain, Ostorius Scapula, began a campaign against the tribes of the western mountains (modern Wales). Caratacus, their leader, was defeated in battle in AD 50 and fled to the Brigantes who occupied the Pennines. Their queen, Cartimandua, came to terms with the Romans and handed Caratacus over to them. Ostorius died and was replaced by Aulus Gallus who brought the Welsh borders under control but did not move further north or west. It was at about this time that the fort at Strutt's Park was built. It probably lay not far south of the border between Roman territory and that held by the Brigantes, who were now an allied or subject kingdom.
 Passage 2:In 1854 Klindworth went to London, where he remained for fourteen years, studying, teaching and occasionally appearing in public. From London Klindworth went to Moscow in 1868, following Nikolai Rubinstein's invitation to take up the position of professor of pianoforte at the Moscow Conservatory, where he first met Pyotr Ilyich Tchaikovsky as professor of harmony. While in Russia he completed his pianoforte arrangements for Wagner's Der Ring des Nibelungen, which he had commenced during Wagner's visit to England in 1855, Beethoven's sonatas and also his critical edition of Frédéric Chopin's works. He then became conductor of the Berlin Philharmonic in 1882, in association with Joseph Joachim and Franz Wüllner, being also the conductor of the Berlin Wagner Society. At this time, he established the Klindworths Musikschule, which later became the Klindworth-Scharwenka Conservatory.
 Passage 3:Kevin Francis (born June 5, 1993) is a professional Canadian football linebacker for the Ottawa Redblacks of the Canadian Football League (CFL). After going undrafted in the 2016 NFL draft, Francis declared eligible for the 2016 CFL Supplemental Draft after informing the league that he was born in Toronto, Ontario. He was drafted by the Roughriders on May 26, 2016, who forfeited a third round selection in the 2017 CFL Draft to acquire his rights. Upon entering 2016 training camp, Francis switched to the defensive side of the ball after playing as a tight end during his college football career with the North Carolina A&T Aggies. He made his CFL debut on June 30, 2016 against the Toronto Argonauts, registering his first defensive tackle. Francis finished his rookie season leading the team in special team tackles, also being ranked 7 on the CFL rising sophomore list

Question: Who was the older of the two - Joe Airey, or the original member of the radar team that Airey joined? Passage 1:This was the first World Series game ever played in Colorado. At 4 hours 19 minutes, it became the longest nine-inning game in World Series history until game five of 2017. Game 3 was also the 600th World Series game ever played. Starting pitcher Daisuke Matsuzaka pitched five innings of scoreless ball and left in the sixth with no runs allowed. The Red Sox struck first with a six-run third inning. Rookie Jacoby Ellsbury hit a leadoff double, moved to third on Dustin Pedroia's single, and scored on David Ortiz's double. After Manny Ramirez was intentionally walked, Mike Lowell's single scored two more runs. J. D. Drew popped out before Ramirez was thrown out at home on Jason Varitek's single with Lowell advancing to third. After Julio Lugo walked to load the bases, Matsuzaka hit a two-run single for his first base hit and RBI in the Major Leagues. Ellsbury capped the scoring with his second double of the inning to knock Colorado starter Josh Fogg out of the game. The Rockies' bats came to life in the sixth and seventh innings against a normally-solid but now-shaky Boston bullpen. After Matsuzaka walked two straight in the sixth with one out, reliever Javier López allowed back-to-back RBI singles to Brad Hawpe and Yorvit Torrealba. Mike Timlin allowed two straight leadoff singles in the seventh before NLCS MVP Matt Holliday brought the Rockies to within one run with a three-run home run off Hideki Okajima. Brian Fuentes gave back those runs in the eighth by walking Lugo with one out and allowing a subsequent single to Coco Crisp before Ellsbury and Dustin Pedroia, who had four and three hits, respectively, on the night (the first time in World Series history two rookies had at least three hits in a game) hit back-to-back RBI doubles, raising Boston's lead to 9–5. Jonathan Papelbon came on for a four-out save, getting Holliday to fly out on one pitch, leaving runners on first and second. Jason Varitek would tack on Boston's tenth run in the top of the ninth off of LaTroy Hawkins with a sacrifice fly, scoring Mike Lowell who, not generally considered a stolen base threat, had just stolen third base—the first time a Red Sox baserunner stole third base in the World Series since 1975—after hitting a leadoff single and moving to second on a sacrifice bunt. Papelbon came back out in the bottom of the ninth to complete the save, getting the first two outs before surrendering a two-out triple to Brad Hawpe, then finishing the game with a groundout from Yorvit Torrealba. The Red Sox took Game 3 by a final score of 10–5.
 Passage 2:Airey was born in Oldham, Lancashire on 25 August 1894. He joined Robert Watson-Watt in 1924, and was an original member of the radar team, responsible for masts and support equipment. He was Senior Technical Officer at Telecommunications Research Establishment. Alongside Arnold Wilkins, Airey is credited with having discovered Bawdsey Manor, Ordfordnessas a site for the Air Ministry department that was significant in the history of radar. In his book "Three Steps to Victory" Robert Watson-Watt proclaims Joe Airey's greatest constructional achievement as the installation of a mast atop the Great Pyramid at Cheops. During World War I, Airey was a member of the Dunsterforce in the Persia and the Middle East. By the time of his retirement, he was Station Engineer at the Royal Radar Establishment. He was appointed a Member of the Order of the British Empire (MBE) for his services by King George VI in his Birthday Honours on 14 June 1945. Airey died in Poole Dorset on 10 February 1976.
 Passage 3:The Venom entered service with the Royal Air Force (RAF), where it was used as a single-seat fighter-bomber and two-seat night fighter. A dedicated model for aerial reconnaissance was also operated by the Swiss Air Force. The Venom functioned as an interim stage between the first generation of British jet fighters – straight-wing aircraft powered by centrifugal flow engines such as the Gloster Meteor and the Vampire – and later swept wing, axial flow-engined combat aircraft, such as the Hawker Hunter and de Havilland Sea Vixen. Accordingly, the type had a relatively short service life in the RAF, being withdrawn from frontline operations by the service in 1962 as a result of the introduction of more capable designs. However, it was used in combat during the Suez Crisis, the Malayan Emergency, and the Aden Emergency.

Question: How many leaders run the priestly class? Passage 1:At the 1988 King of the Ring tournament, Bass qualified for the final after beating a young Shawn Michaels but was paid by Ted DiBiase to fake an injury. Bass began a feud with Beefcake in August 1988, gouging Beefcake's head open with his spurs ("Bret" and "Bart") on an episode of Superstars of Wrestling; the attack caused Beefcake to miss his scheduled Intercontinental championship match against the Honky Tonk Man at the first SummerSlam event on August 29. Bass and Honky co-captained a five-man contingent against a team captained by Beefcake and the Ultimate Warrior at the second Survivor Series in November. Bass and teammate Greg Valentine were eliminated by Warrior in succession in the final minute of the match. On the January 7, 1989 Saturday Night's Main Event XIX, Bass lost to Beefcake via sleeperhold in a hair vs. hair match. He competed in the 1989 Royal Rumble (sans hair), Bass' feud with Beefcake was scrapped, and he was used mainly as a preliminary wrestler and left the WWF shortly thereafter.
 Passage 2:Traditional African religions like the Serer religion (A ƭat Roog) are adhered to by devout worshippers of Roog – the supreme deity in Serer religion. The Serer ethnic group who adhere to the tenets of Serer religion (including those Senegalese who syncretize) honour the Serer pangool and have ancient rituals and festivals devoted to them. The religious affairs of Serer religion devotees are usually headed by the Saltigue (the Serer priestly class) which in ancient times was the preoccupation of the Serer lamanic class. Some of these religious festivals or ceremonies include the Ndut (rite of passage), Xooy (divination festival once a year in Fatick), and the Raan festival. Senegalese hold several ancient beliefs, such as small efforts of 'thanks' or demands, such as protection from water. They also place great importance on the Baobab tree, which is known as the "House of the Spirits." The baobab tree along with other sacred trees figure prominently in the Serer creation narrative. Among the Jola people, some religious festivals include the Samay, Kumpo and the Niasse.
 Passage 3:In humans C. hepatica causes Hepatic capillariasis, a serious liver disorder. The Nematode wanders through the host liver causing loss of liver cells and thereby loss of function. However, as the adult C. hepatica begin to die in the liver tissue, their decomposition accelerates the immune response of the host. This response leads to chronic inflammation and Encapsulation of the dead worms in collagen fibers, and eventually to septal fibrosis (abnormal connective tissue growth) and cirrhosis of the liver. This leaves the eggs behind and they can become encased by Granulomatous tissue, with large sections of the Parenchyma becoming replaced by these egg masses. Capillaria hepatica can also cause Hepatomegaly. Infections of C. hepatica can present with several clinical symptoms including, abdominal pain in the liver area, weight loss, decreased appetite, fever and chills, hepatitis (liver inflammation), ascites (excess fluid in the peritoneal cavity) and hepatolithiasis (gallstones in the bile ducts).
