Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

New input: Question: How old was the last Prince of Morgannwg when he died? Passage 1:Jenkins was born in Merthyr Tydfil, Glamorgan on 30 January 1828. His father, William David Jenkins, could allegedly trace his ancestry back to Iestyn ap Gwrgant, the last Prince of Morgannwg. After attending Taliesin Williams's school in Merthyr Tydfil and Cowbridge Grammar School, Jenkins studied at Oxford University, matriculating at Jesus College in 1846 with the benefit of the Sir Leoline Jenkins scholarship. He studied Literae Humaniores, obtaining a third-class BA degree in 1850. He subsequently obtained further degrees: M.A. in 1852, BD in 1859 and DD in 1871. He became a good classical and oriental scholar whilst at Oxford, developing a fluency in modern languages in later life. Whilst an undergraduate, he tried and failed on several occasions for the Pusey and Ellerton Hebrew Scholarship; after his final failure, Dr Pusey presented him with some books to acknowledge his abilities in Hebrew.
 Passage 2:The Sweden national football team has traditionally been a strong team in international football, with eleven World Cup appearances—collecting one silver and two bronze medals—and three medals in the Olympics, including one gold. Sweden played its first international game against Norway in 1908 and competed in an international tournament, the Summer Olympics, for the first time the same year. Since then, Sweden has regularly qualified for the World Cup and the Olympics as well as the European Championships. The best results in the World Cup are a second place (as hosts) in the 1958 and two third places in 1950 and 1994. In the Olympics, Sweden has won the gold medal in 1948 as well as two bronze medals in 1924 and 1952. The best result in the European Championship is a semi-final loss in 1992 as hosts of the tournament.
 Passage 3:In 1996 Guillermo Martinez began wrestling under the name "Bombero Infernal", complete with a mask and ring gear adorned in flames and diabolical images. He had only worked under that name for just over a year when he became involved in a storyline feud against El Pantera, the rivalry escalated to the point where both wrestlers agreed to put their masks on the line in a Lucha de Apuestas, or "bet match", the most prestigious match type in Lucha Libre. The match took place on December 7, 1997 in International Wrestling Revolution Group's (IWRG) Arena Naucalpan in Naucalpan, State of Mexico with Bombero Infernal losing the match, which forced him to unmask in the middle of the ring, state his birthname and how long he had been a wrestler. Oftentimes losing the mask means the end of a specific ring character, but Martinez stuck with the Bombero Infernal ring characters in the years after his loss. On January 10, 1999 Bombero Infernal won the IWRG Intercontinental Middleweight Championship from Mr. Niebla and held the championship for 146 days straight. The title change was part of a long running storyline between Bombero and Mr. Niebla that saw Mr. Niebla regain the championship on June 6, 1999 but ultimately lose it to Bombero Infernal once again on October 24, 1999. His second reign ended at the hands of Último Vampiro on December 16, 1999 when he defeated Bombero Infernal. In late 2000 Bombero Infernal teamed up with Cripta and El Enterrador to defeat the team of Super Caló, Alan Stone and Moto Cross to win the Distrito Federal Trios Championship. On November 19, 2000 Bombero Infernal regained the IWRG Intercontinental Middleweight Championship from Último Vampiro. Bombero's time as a double champion ended on February 11, 2001 when Los Oficiales (Guardia, Oficial and Virgilante) won the DF Trios Championship. A month later he also lost the Middleweight Championship to Black Dragon. Later that year Bombero Infernal defeated Último Vampiro to win the Middleweight Championship for a fourth time, at the time someone other than the previous Último Vampiro was playing the character. The match between the two ended in a controversial fashion, leading IWRG to take the championship away from Bombero Infernal only one week later. In 2002 Bombero Infernal rekindled his storyline with El Pantera, going so far as to put his hair on the line against Pantera's Middleweight Championship, in a match that saw Bombero victoriously claim his fifth IWRG Intercontinental Middleweight Championship. His fifth reign lasted 95 days in total before it coming to an end when Tony Rivera defeated him. On November 11, 2002 Bombero Infernal, El Hijo del Diablo and El Engendro defeated Dr. Cerebro, Cirujano and Paramedico to win the DF Trios Championship once again, a title they would quickly lose to a new group called Los Megas (Mega, Omega and Ultra Mega)
