Example: 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 case for you: Question: When was Joan Arches' son born? Passage 1:Maachi began his career as a youth player at Utrecht. He made his first team debut during the 2005–06 season and spent the following year on loan with Dordrecht. He joined Cambuur in 2008 and spent three seasons with the club before being transferred to Zwolle, initially on loan and then permanently during the summer of 2011. In summer 2012, Maachi joined technical director Kevin Hofland at Cypriot side AEK Larnaca. After an unsuccessful stint in Albania, Maachi moved to Birkirkara in January 2015. In the next two years he played in Cyprus for Pafos FC and Nea Salamina. On 18 June 2016, the newly promoted to Greek Super League club Apollon Smyrni officially announced the signing of the experienced Dutch-Moroccan forward on a free transfer. At the end of August 2018, Maachi joined VV DOVO which competes in the Derde Divisie. At the end of 2018 he left there again to return to Cyprus.
 Passage 2:The status of Jerusalem is disputed in both international law and diplomatic practice, with both the Israelis and Palestinians claiming Jerusalem as their capital city. The dispute has been described as "one of the most intractable issues in the Israel–Palestine conflict", with conflicting claims to sovereignty over the city or parts of it, and access to its holy sites. The main dispute revolves around the legal status of East Jerusalem and especially the Old City of Jerusalem, while broader agreement exists regarding future Israeli presence in West Jerusalem in accordance with Israel's internationally recognised borders. The majority of United Nations (UN) member states hold the view that the final status of Jerusalem should be resolved through negotiation, and have therefore favored locating their embassies in Tel Aviv prior to a final status agreement. However, in recent years the international consensus to abstain from expressing a viewpoint on the city's final status has shown signs of fragility, with Russia, the United States and Australia adopting new policy positions. Furthermore, the proposal that Jerusalem should be the future capital of both Israel and Palestine has also gained international support, with endorsements coming from both the United Nations and the European Union.
 Passage 3:By 1196 Hugh de Say, grandson of Hugh FitzOsbern, had transferred lordship of the manor of Souldern to his brother-in-law Thomas de Arderne. By 1279 the Ardernes were mesne lords, collecting rent from the de Lewknor family. By 1307 the de Lewknors had conveyed Souldern to the Abberbury family of Donnington, Berkshire. Sir Richard Abberbury, knight of the shire for Oxfordshire in 1373 and 1387, granted lands at Souldern to both Donnington Hospital and a house of Crutched Friars at Donnington. Sir Richard's nephew, another Richard Abberbury, inherited the remainder. The younger Richard seized the Crutched Friars' land at Souldern and granted it to William de la Pole, 1st Duke of Suffolk in 1448. The remainder of Richard's land at Souldern passed to his nephew Sir Richard Arches (d.1417), MP for Buckinghamshire in 1402, of Eythrope, Cranwell (both in the parish of Waddesdon) and Little Kimble, Buckinghamshire. Souldern was inherited by his daughter Joan Arches and her husband Sir John Dynham. When their son, John Dynham, 1st Baron Dynham, died in 1501, Souldern manor was divided into four parts which remained in separate hands until the 1590s.
