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.

Reason: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this instance: Question: Which country won the most gold medals at the Olympics during which the Munich massacre took place? Passage 1:On 15 August 2018, a British political controversy was initiated when the Daily Mail claimed that, prior to becoming Labour Party Leader, Jeremy Corbyn had been present at a 2014 wreath-laying at a cemetery which contained the graves of many Palestinian activists including Salah Khalaf and Atef Bseiso, both of whom were members of the Black September Organization and were behind the Munich massacre of Israeli athletes at the 1972 Summer Olympics. The wreath-laying took place during a commemorative ceremony for victims of the 1985 Israeli air strikes on the PLO headquarters in Tunis, Tunisia, which had been widely condemned at the time, including by the U.S. Government. Corbyn and the Conservative peer Baron Sheikh had been in Tunisia to attend the International Conference on Monitoring the Palestinian Political and Legal Situation in the Light of Israeli Aggression. The controversy was considered to be part of a wider series of issues relating to claims of antisemitism in the Labour party and Corbyn's personal position on the Middle East, which have escalated since Corbyn became a front-runner for Labour Party leader in August 2015.
 Passage 2:In 1994, he was introduced to Erick Sermon of EPMD by his friend K-Solo. Sermon included Murray on his album No Pressure on the single "Hostile", with critics praising Murray's lyrical ability. His appearance on Hostile led to Murray being signed to Jive Records, and work began on his first album. Murray's debut single, The Most Beautifullest Thing in This World was released in 1994 and was a hit. The song was produced by Erick Sermon (who also provided background vocals) and peaked at number 50 on the Billboard 200 and number 3 on the Hot Rap Singles chart. Murray's debut album The Most Beautifullest Thing in This World, was named after the single and released in 1994 to widespread critical acclaim and commercial success, being certified Gold by the Recording Industry Association of America (RIAA) in August 1995. The album was also given 4 mics by The Source. Murray continued to enjoy a high media-profile by appearing on a Coca-Cola advertisement and as a featured guest on Mary J Blige’s Be Happy, Total’s Can’t You See, R Kelly's Home Alone and LL Cool J’s I Shot Ya.
 Passage 3:Yet again, Town's season was dominated by their FA Cup run. They reached their fifth and so far last FA Cup Final. After a win over Hull City in Round 3, they scraped past Notts County and Liverpool, they beat York City in the quarter-final in a replay, before beating the favourites Sunderland at Ewood Park in the semi-final, meaning they would play Preston North End in the final, a repeat of the 1922 FA Cup Final, the only one of Town's previous final appearances that they won. The final at Wembley was the first since moving to the London stadium to go into extra time. The result would be the opposite to the 1922 final, with Town conceding a penalty to lose the match 1–0.
