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.

Problem: Question: From what university did the person McGeoch studied under at the University of Chicago graduate? Passage 1:McGeoch was born on October 9, 1897 in Argyle, New York. He received his bachelor's degree from Westminster College in 1918, and a master's degree from Colorado College in 1919. His master's thesis, titled "The Present Status of Psychology", is a review of the history of the field of psychology and how the role of psychology was viewed in the early 20th century. He then studied under Harvey A. Carr at the University of Chicago. He studied a variety of topics while at the University of Chicago, including suggestibility and intelligence in delinquents, time perception, neuropsychological and vocational testing, and the reliability and validity of the Pressey X-O test. His doctoral dissertation was titled "A study in the psychology of testimony." Following the completion of his dissertation, McGeoch’s work primarily focused on human learning and memory. Harvey Carr significantly influenced McGeoch’s work, and provided feedback on the McGeoch's introductory textbook on human learning, The Psychology of Human Learning, which was published after Carr’s death in 1943. McGeoch completed his PhD while he was a faculty member at the University of Washington. He accepted a full Professor position 2 years later at the University of Arkansas. In 1930 he moved to the University of Missouri where he became the chair of the department of psychology. He held this position for 5 years before moving to Wesleyan University, where he was also chair of the department from 1935–1939 and was awarded an honorary degree in recognition of his accomplishments as a lecturer and administrator. In 1939, McGeoch moved to the University of Iowa, where he also chaired the department. He died in Iowa City on March 3, 1942 from a cerebral hemorrhage.
 Passage 2:There was one driver change heading into the race. Having been in one of the Aguri cars since the first round of the season in Beijing, António Félix da Costa missed the ePrix because of a Deutsche Tourenwagen Masters commitment at the Red Bull Ring and was replaced by endurance racing driver René Rast. The deal was confirmed in the week before the race and was originally slated to be World Endurance Championship driver Adam Carroll but the agreement fell apart. It marked Rast's first participation in single-seater machinery since the Formula BMW ADAC in 2004 and practised on the team's simulator to familiarise himself with the car. Oliver Turvey was set to be replaced by the Formula Renault 3.5 driver Ben Hanley because of a Super GT commitment at the Autopolis circuit, but that race was postponed because of the Kumamoto earthquakes, and his Formula E seat was reinstated.

The New York Giants used the song as their entrance song in Super Bowl XLVI on 5 February 2012. It was also used in the closing ceremony of the London Olympic Games in August 2012. In May 2016, Tempah performed the song live in Wembley Stadium before the FA Cup final.
