Problem:Question: How many years had David Hamilton been a professional when he designed 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: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.
 Passage 3: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.
