Example input: 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.

Q: Question: Which city that Garden Grove borders has the largest population?  Passage 1:Smith began his managerial career with Bury in November 1973, taking over from Allan Brown. At the age of 29 he was the youngest manager in the Football League. He had initial success, guiding Bury to promotion from the Fourth Division in the fourth automatic place at the end of the 1973–74 season. He stabilised the Gigg Lane outfit in the Third Division in 1974–75 with a 14th-place finish. They went on to finish 13th in 1975–76, before finishing five points off the promotion places in 1976–77. He was sacked by Bury on 16 November 1977 after a poor start to the season. The "Shakers" finished the 1977–78 campaign in 15th place under the stewardship of Bob Stokoe.
 Passage 2:West Grove, officially recognized as the West Grove Business District by the City of Garden Grove, and sometimes called West Garden Grove, is a neighborhood in the city of Garden Grove, located in Orange County, California, United States. West Grove encompasses the pene-exclave western portion of the city of Garden Grove. It is bordered to the north by Cypress, to the west by Los Alamitos and Seal Beach, to the south by Westminster, and to the east by Stanton, and connected to the rest of Garden Grove by a narrow strip along Garden Grove Boulevard. It includes the entire 92845 ZIP Code, which is designated as the areas west of Knott Avenue to the Seal Beach and Los Alamitos city borders, and the industrial area east of Knott Avenue to the Stanton border. The community is more "affluent" than the rest of Garden Grove, with a median income $25,000 greater than the main body of the city. There is also less crime, a lower poverty rate, and the population density is lower compared to the rest of Garden Grove. As of the 2010 Census, 16,333 people reside in West Grove.
 Passage 3:Nirvana released its first single, a cover of Shocking Blue's "Love Buzz", in November 1988 on the Seattle independent record label Sub Pop. They did their first ever interview with John Robb in Sounds who also made the release single of the week. The following month, the band began recording its debut album, Bleach, with local producer Jack Endino. Bleach was highly influenced by the heavy dirge-rock of the Melvins and Mudhoney, 1980s punk rock, and the 1970s heavy metal of Black Sabbath. Novoselic said in a 2001 interview with Rolling Stone that the band had played a tape in their van while on tour that had an album by The Smithereens on one side and an album by the extreme metal band Celtic Frost on the other, and noted that the combination probably played an influence as well. The money for the recording sessions for Bleach, listed as $606.17 on the album sleeve, was supplied by Jason Everman, who was subsequently brought into the band as the second guitarist. Though Everman did not actually play on the album, he received a credit on Bleach because, according to Novoselic, they "wanted to make him feel more at home in the band". Just prior to the album's release, Nirvana insisted on signing an extended contract with Sub Pop, making the band the first to do so with the label.
