[EX Q]: Question: What country is it perceived that Marcos went on a diplomatic mission to in 1417? Passage 1:He first appears in Constantinople in 1401, qualified as an oikeios of the emperor. In 1417 he was possibly sent on a diplomatic mission to the Venetians in the Morea. In 1422 and again in 1429 he was sent by Emperor John VIII Palaiologos as an envoy to the Ottoman Sultan Murad II. At the time he had the relatively lowly rank of protovestiarites, but was quickly promoted to protostrator and then to the senior rank of megas stratopedarches, which he held already during his mission in 1430 to Pope Martin V. During his return from the mission to the Pope, on orders from the Emperor, he raised Thomas Palaiologos to the rank of Despot in the Morea. He led two more missions abroad, one in 1433 to Pope Eugene IV, and one in 1438 to Venice.
 Passage 2:Truman had acceded to the presidency in April 1945 after the death of Franklin D. Roosevelt. Defeating attempts to drop him from the ticket, Truman won the presidential nomination at the 1948 Democratic National Convention. The Democratic convention's civil rights plank caused a walk-out by several Southern delegates, who launched a third-party "Dixiecrat" ticket led by Governor Strom Thurmond of South Carolina. The Dixiecrats hoped to win enough electoral votes to force a contingent election in the House of Representatives, where they could extract concessions from either Dewey or Truman in exchange for their support. Truman also faced a challenge from the left in the form of former Vice President Henry A. Wallace, who launched the Progressive Party and challenged Truman's confrontational Cold War policies. Dewey, who was the leader of his party's moderate eastern wing and had been the 1944 Republican presidential nominee, defeated Senator Robert A. Taft and other challengers at the 1948 Republican National Convention.
 Passage 3:The 2nd World Water Forum held in The Hague in March 2000 raised some controversies that exposed the multilateral nature and imbalance the demand and supply management of freshwater. While donor organizations, private and government institutions backed by the World Bank, believe that freshwater should be governed as an economic good by appropriate pricing, NGOs however, held that freshwater resources should be seen as a social good. The concept of network governance where all stakeholders form partnerships and voluntarily share ideas towards forging a common vision can be used to resolve this clash of opinion in freshwater management. Also, the implementation of any common vision presents a new role for NGOs because of their unique capabilities in local community coordination, thus making them a valuable partner in network governance.

[EX Q]: Question: Where did Preston Bassett work the year his sister got married? Passage 1:Wasson was born Isabel Deming Bassett in Brooklyn, NY on January 11, 1897, daughter of urban planner Edward Bassett and Annie Preston Bassett, and sister of inventor and engineer Preston Bassett. Wasson graduated Phi Beta Kappa from Wellesley College in 1918, majoring in history so she could take a wide range of science courses. She took classes in geology after graduation at the University of Chicago and the Massachusetts Institute of Technology. She met her future husband, petroleum geologist Theron Wasson, whom she married in 1920, while working towards a master's degree in geology at Columbia University, which she finished in 1934. They had three children: Elizabeth W. Bergstrom, a biologist; Edward B. Wasson, a petroleum geologist; and Anne Harney Gallagher, an art historian. Wasson worked as a petroleum geologist in her husband's office at the Pure Oil Company from the early 1920s until 1928. She published two scholarly articles on geology, one co-authored with her husband about an oil field discovered by Pure Oil in 1914, and another by herself about the ages of rock formations in Ohio and new terminology for them; the latter was cited in a number of other papers and a recent book. After 1928 she spent over 50 years in River Forest, IL, teaching science in the local public schools, lecturing, bird watching (ornithology), and mentoring generations of young naturalists. She was quoted in this 1986 Chicago Tribune article as an expert on local geology at age 89. She was honored for her contributions to local history in 1982 when the Wasson Room was named after her in a local school to hold local history resources. Her interests included archaeology; she discovered a Native American religious mound in Thatcher Woods, near her house in River Forest, in the 1930s. An article about her discovery called her "the one who started the environmental education movement in America back in the 1920s and '30s." Theron and Isabel divorced in 1953 and she did not remarry. From 1953-1954, Wasson served as President of the Chicago Ornithological Society. Wasson also taught classes at the Morton Arboretum in Lisle, Illinois. She died in La Grange Park, IL, in 1994.

She also performed during the ceremony, entertaining the crowd with a medley of her songs "...Baby One More Time" and "(You Drive Me) Crazy". The Free Your Mind Award, which honours an individual or organisation for aiding in humanitarian efforts and fighting prejudice, was given to Bono for his world peace work. Puff Daddy performed "My Best Friend" backed by a full gospel choir, followed by Iggy Pop, who stagedived into the crowd during the track "Lust for Life". Whitney Houston sang a medley of "Get It Back" and "My Love Is Your Love", while Mariah Carey performed "Heartbreaker".

 Passage 3:Born in Bedford on 22 September 1780, John Hensman was educated at Bedford School and at Corpus Christi College, Cambridge, where he matriculated as an Exhibitioner in February 1797. He graduated as ninth Wrangler at the University of Cambridge in 1801 and was elected as a Fellow of Corpus Christi College, Cambridge. He was ordained in 1803, and was appointed as Curate of Wraxall, Somerset. In 1809 he was appointed as Curate of Clifton, Bristol. He was instrumental in the rebuilding of Clifton parish church, which was consecrated on 12 August 1822. He was then the moving force behind the building of the Church of Holy Trinity, Hotwells, which was consecrated on 10 November 1830. He held the incumbency of the church until 1844, when he was granted the perpetual curacy of Christ Church, Clifton Down, and he oversaw the rebuilding of that church. He was instituted to the living of Clifton, Bristol, in 1847, and oversaw the building of St Paul's Church, Clifton, Bristol, consecrated in 1853, and St Peter’s Church, Clifton, consecrated in 1855.

[EX Q]: Question: What was the total cost of The Nelson Monument overlooking Portsmouth and The Nelson Monument on Glasgow Green? Passage 1:Roger Federer won the Australian Open, beating Briton Andy Murray, whom he also beat in the final of the 2008 US Open. Federer played in eighteen tournaments in 2010, and won five. He made the semifinals of his opening tournament at the Qatar Open in Doha, losing to Nikolay Davydenko, and at the Estoril Open, which he had won in 2008, losing to defending and eventual champion Albert Montañés. Federer was runner-up in the Mutua Madrileña Madrid Open to Rafael Nadal. At the French Open, he faced his opponent in the previous year's final, Robin Söderling at the quarterfinals stage and lost. As defending champion at Wimbledon, he was defeated in the quarterfinals by Tomáš Berdych in four sets, thus ending his streak of seven consecutive Wimbledon finals also falling to world no. 3, his lowest ranking since 2003. During the summer hard-court season, Federer hired Paul Annacone to be his coach and revive his form. At the 2010 US Open, Federer advanced to his seventh straight semifinal appearance, but lost to Novak Djokovic in five sets, despite holding two match points in the final set. Federer's ranking slipped from no. 2 to no. 3 after the tournament, but he finished the year strong with victories in Stockholm, Basel, and the ATP Tour Finals to pass Djokovic in the rankings and finish the year at no. 2. By the end of 2010 Roger Federer became widely considered as the greatest male tennis player of all time.
 Passage 2:Sin Salida (2015) (Spanish for "No Escape"/"No Exit") was a major professional wrestling event produced by the Mexican Lucha Libre-promotion Consejo Mundial de Lucha Libre (CMLL) that took place on Friday night July 17, 2015, in CMLL's main venue, Arena México, nicknamed "the cathedral of Lucha Libre" in lieu of CMLL's normally scheduled Super Viernes ("Super Friday") show. The main event was a best two-out-of-three falls Lucha de Apuestas, or bet match where both Rey Escorpión and Último Guerrero "bet" their hair on the outcome of the match and the loser was forced to have all his hair shaved off afterwards as per Lucha Libre traditions. The show also hosted two first-round matches of CMLL's 2015 En Busca de un Ídolo ("In Search of an Idol") tournament where Esfinge wrestled Canelo Casas and Delta was supposed to face Blue Panther Jr., but wrestled Hechicero instead. The show contained four additional matches. Although it was not announced ahead of time, the first six matches of the show were broadcast live on the Terra Networks' home page for free.
 Passage 3:Nelson became – and remains – Britain's greatest naval war hero, and an inspiration to the Royal Navy, yet his unorthodox tactics were seldom emulated by later generations. The first monument to be erected in Britain to commemorate Nelson may be that raised on Glasgow Green in 1806, albeit possibly preceded by a monument at Taynuilt, near Oban in Scotland dated 1805, both also commemorating the many Scots crew and captains at the battle. The Nelson Monument on Glasgow Green was designed by David Hamilton and paid for by public subscription. Around the base are the names of his major victories: Aboukir (1798), Copenhagen (1801) and Trafalgar (1805). The Nelson Monument overlooking Portsmouth was built in 1807–08 with money subscribed by sailors and marines who served at Trafalgar. In 1808, Nelson's Pillar was erected by leading members of the Anglo-Irish aristocracy in Dublin to commemorate Nelson and his achievements (between 10% and 20% of the sailors at Trafalgar had been from Ireland), and remained until it was destroyed in a bombing by "Old IRA" members in 1966. Nelson's Monument in Edinburgh was built between 1807 and 1815 in the form of an upturned telescope, and in 1853 a time ball was added which still drops at noon GMT to give a time signal to ships in Leith and the Firth of Forth. In summer this coincides with the one o'clock gun being fired. The Britannia Monument in Great Yarmouth was raised by 1819. Nelson's Column, Montreal began public subscriptions soon after news of the victory at Trafalgar arrived; the column was completed in the autumn of 1809 and still stands in Place Jacques Cartier.
