Question: What was the first flight with Charlesworth as the flight director to involve extravehicular activity? Passage 1:Clifford Eugene Charlesworth was born on November 29, 1931, in Red Wing, Minnesota, and grew up in Mississippi. He completed his education at Mississippi College with a bachelor's degree in physics in 1958. After a time as a civil servant with the United States Navy and the Pershing missile program of the United States Army, he joined NASA in 1962. He worked at the Manned Spacecraft Center in Houston, Texas, until 1970. He served as the Flight Director on Gemini 11 and Gemini 12, and as one of the Flight Directors on Apollo 8, the first mission to orbit the Moon; Apollo 11, the first mission to land on the Moon; and Apollo 12, the second Moon landing mission. From 1970 to 1972 he was manager of the Earth observation satellite program. He then worked as Deputy Head of the Payload Section of the Space Shuttle program, as Deputy Director of the Johnson Space Center, and as Director of Space Operations before he retired in 1988.
 Passage 2:Merivale was the second son of John Herman Merivale (1770–1844) and Louisa Heath Drury, daughter of Joseph Drury, headmaster of Harrow. He was educated at Harrow School under George Butler from 1818 to 1824, where his chief schoolfriends were Charles Wordsworth and Richard Chenevix Trench. He took part in the Eton versus Harrow cricket match in 1824. In 1824 he was offered a post in the Indian civil service, and went for a short time to Haileybury College, where he did well in Oriental languages. Deciding against an Indian career, he went up to St John's College, Cambridge in 1826. Among other distinctions he came out as fourth classic in 1830, and in 1833 was elected fellow of St John's. He was a member of the Apostles' Club, his fellow-members including Tennyson, A. H. Hallam, Monckton Milnes, W. H. Thompson, Trench and James Spedding. Merivale was the main protagonist on the Cambridge side in instigating the Oxford and Cambridge Boat Race held at Henley on Thames in 1829. He rowed at number four in the Cambridge boat in the race which Oxford won.

Question: How old was Tony Benn the year that he beat Malcolm St. Clair in the London County Council elections, in Islington East? Passage 1:A major proponent of representative government was Itagaki Taisuke, a powerful leader of Tosa forces who had resigned from his Council of State position over the Korean affair in 1873. Itagaki sought peaceful rather than rebellious means to gain a voice in government. Such movements were called The Freedom and People's Rights Movement. He started a movement aimed at establishing a constitutional monarchy and a national assembly. Itagaki and others wrote the Tosa Memorial in 1874 criticizing the unbridled power of the oligarchy and calling for the immediate establishment of representative government. Dissatisfied with the pace of reform after having rejoined the Council of State in 1875, Itagaki organized his followers and other democratic proponents into the nationwide Aikokusha (Society of Patriots) to push for representative government in 1878. In 1881, in an action for which he is best known, Itagaki helped found the Jiyūtō (Liberal Party), which favored French political doctrines. In 1882 Ōkuma Shigenobu established the Rikken Kaishintō (Constitutional Progressive Party), which called for a British-style constitutional democracy. In response, government bureaucrats, local government officials, and other conservatives established the Rikken Teiseitō (Imperial Rule Party), a pro-government party, in 1882. Numerous political demonstrations followed, some of them violent, resulting in further government political restrictions. The restrictions hindered the political parties and led to divisiveness within and among them. The Jiyūtō, which had opposed the Kaishintō, was disbanded in 1884, and Ōkuma resigned as Kaishintō president.
 Passage 2:The Sex Pistols evolved from the Strand, a London band formed in 1972 with working-class teenagers Steve Jones on vocals, Paul Cook on drums and Wally Nightingale on guitar. According to a later account by Jones, both he and Cook played on instruments they had stolen. Early line-ups of the Strand—sometimes known as the Swankers—also included Jim Mackin on organ and Stephen Hayes (and later, briefly, Del Noones) on bass. The band members regularly hung out at two clothing shops on the King's Road in Chelsea, London: John Krivine and Steph Raynor's Acme Attractions (where Don Letts worked as manager) and Malcolm McLaren and Vivienne Westwood's Too Fast to Live, Too Young to Die. McLaren's and Westwood's shop had opened in 1971 as Let It Rock, with a 1950s revival Teddy Boy theme. It had been renamed in 1972 to focus on another revival trend, the rocker look associated with Marlon Brando. As John Lydon later observed, "Malcolm and Vivienne were really a pair of shysters: they would sell anything to any trend that they could grab onto." The shop became a focal point of the punk rock scene, bringing together participants such as the future Sid Vicious, Marco Pirroni, Gene October, and Mark Stewart, among many others. Jordan, the wildly styled shop assistant, is credited with "pretty well single-handedly paving the punk look".
 Passage 3:In 1955, he stood unsuccessfully as a Conservative candidate at the London County Council elections, in Islington East. At the 1959 general election he stood as Conservative candidate in Bristol South East, but he lost to the sitting Labour Member of Parliament Tony Benn (then known as Anthony Wedgwood Benn), whose majority was nearly 6,000 votes. However, in November 1960 Benn's father died and Benn inherited his peerage as Viscount Stansgate, with an automatic seat in the House of Lords. This disqualified Benn from sitting in the House of Commons, triggering a by-election on 4 May 1961. Benn, who wished to be allowed to disclaim his peerage, defied his inability to sit in the Commons by standing at the election, and he and St Clair were the only two candidates. St Clair's campaign displayed posters near every polling station warning voters that Benn was disqualified and that any votes for him would have no effect. Benn nevertheless won the election with nearly 70% of the votes and an increased majority of over 13,000. However, an Election Court considered what to do about the result, found that Benn was disqualified from being elected and that the voters were aware of this, and awarded the seat to St. Clair as the only duly qualified candidate. (At the time, St Clair was himself Master of Sinclair – heir presumptive (1957–1968) to his second cousin Charles St Clair, 17th Lord Sinclair, one of the representative peers for Scotland in the House of Lords.)

Question: What are the names of the other teams in the AFC North division? Passage 1:On October 13, 2000 El Oriental defeated Super Crazy to win the UWA World Welterweight Championship, his first AAA promoted championship ever. He held the title until early 2001 when he was forced to vacate the title after being injured during a match. After recovering from his injury El Oriental participated in the 2002 Rey de Reyes tournament, but was eliminated by Cibernético in the opening round. At Triplemania X he was one of six wrestlers who participated in the main event. Each of the six wrestlers bet the hair of a referee on the outcome of the match. El Oriental represented referee Hijo del Tirantes in the match, but was not involved in the finish of the match as Heavy Metal pinned Sangre Chicana. Between late 2002 and mid-2003 El Oriental suffered various injuries that kept him out of the ring for long stretches of time. At the 2003 Guerra de Titanes Cynthia Moreno, El Oriental, Mascarita Sagrada and Pimpinela Escarlata defeated Faby Apache, Gran Apache, Mini Abismo Negro and Polvo de Estrellas in a Relevos Atómicos de locura match (Spanish for "Eight-man madness match"), a match that featured two teams of four, each composed of a male wrestler, a female wrestler, an Exótico wrestler and a Mini-Estrella In the mid-2004 El Oriental's sister Cynthia started a storyline feud with the Apache family, primarily Faby Apache and Gran Apache that would last until 2009. On August 1, 2004 Cynthia and El Oriéntal unsuccessfully challenged for the AAA World Mixed Tag Team Championship, losing to Gran Apache and Faby Apache. The teams would subsequently clash on several occasions, with the Apaches managing to retain the mixed titles each time. In 2005 the Apaches were forced to vacate the Mixed tag team titles, after which AAA held a tournament to crown new champions. Cynthia and El Oriéntal defeated Gran Apache and Tiffany in the semi-final and then defeated Chessman and La Diabólica in a one night tournament at Verano de Escandalo to become the new AAA World Mixed Tag Team Champions. Over the next 779 days Cynthia and El Oriéntal would repeatedly defend the Mixed tag team titles, including defending them on various independent shows. Their reign would come to an end in November, 2007 when they were forced to vacate the championship when Cynthia suffered an injury and was unable to defend the titles. While Cynthia was recuperating from an injury Gran Apache and Mari Apache won the vacant title as well as turning técnicos (good guys) in the process. When Cynthia returned to the ring she and her brother turned rudo (bad guy) when they attacked Gran and Mari Apache after a successful title defense. At the 2008 Verano de Escandalo Oriental and Cynthia Apache regained the AAA World Mix Tag Team Championship from the Apaches, making them the only team to have held the title twice. The Dinastia Moreno's second reign with the tag team titles turned out to be as active as their first, in fact El Oriental once claimed they defended the titles around 150 times, although records do not support such a claim. In mid-2009 Cynthia began appearing less and less on AAA shows, leaving El Oriental free to team up with Kenzo Suzuki and Sugi San to form a trio called La Yakuza, after the Japanese Mafia. The team started out with a series of victories, but were defeated by Los Psycho Circus at the 2009 Verano de Escandalo. Following the event Sugi San left AAA and La Yakuza disbanded. In the fall of 2009 both Cynthia and El Oriéntal left AAA, losing the Mixed Tag Team title to Faby Apache and Aero Star as their last match for AAA.
 Passage 2:To create the hip-hop and rock fusions on the album, Jimmy Pop utilized the standard hip hop technique of sampling. The chorus for "Fire Water Burn" is taken from "The Roof Is on Fire" by Rock Master Scott & the Dynamic Three and also features the lyrics 'I am white like Frank Black is / So if man is five and the devil is six then that must make me seven / This honkey's gone to heaven,' a direct reference to the post-1993 stage name of Black Francis who wrote the Pixies song "Monkey Gone to Heaven" to which the lyrics allude. "Why's Everybody Always Pickin' On Me?" is built around a re-recorded sample of "Spooky", by Mike Sharpe as performed by Classics IV and also features a small lift from the Bill Cosby track "Greasy Kid Stuff." Finally, the track "Your Only Friends Are Make Believe" features a chorus melody lifted from the Duran Duran song "Hungry Like the Wolf." "Lift Your Head Up High (And Blow Your Brains Out)" is built around a sample from "Get Up and Boogie" by the Silver Convention.
 Passage 3:The Pittsburgh Steelers compete in the National Football League (NFL) as a member club of the American Football Conference (AFC) North division. Founded in 1933, the Steelers are the oldest franchise in the AFC; seven franchises in the National Football Conference (NFC) have longer tenures in the NFL. The team struggled to be competitive in its early history, posting winning records in just 8 of its first 39 seasons. Since the AFL–NFL merger in 1970, however, it has appeared in eight Super Bowls and one of only two teams, along with the New England Patriots have won the Super Bowl six times. The six championships place the Steelers fourth in the league in terms of total championships (including those prior to the first Super Bowl), trailing only the Green Bay Packers (13 championships), the Chicago Bears (9) and the New York Giants (8). The club's 15 AFC Championship Game appearances are second all-time, behind the Patriots (16). In addition, they have hosted the second-most conference championship games (11) than any franchise in either conference, and are tied for second with the Dallas Cowboys and Denver Broncos with eight Super Bowl appearances; the Patriots currently hold the record of eleven appearances, as of 2019.
