In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
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: How many songs on What To Do About Them had been previously unreleased? Passage 1:In 1992 the band signed to Taang! Records and released the eight-song mini-album What To Do About Them culled from a mix of previously available and unreleased home and studio recordings. Musician/cartoonist Ron Regé, Jr. contributed artwork to the album's cover as well as lo-fi recordings that were woven into the record's sequence. The band also set to work recording their first LP, around which time shifts in Swirlies' personnel began to occur. Ben Drucker only drummed on a third of the new album's studio tracks, and for the remaining songs his parts were handed over to a pair of session drummers. Andy Bernick departed to pursue ornithology for the academic year and Damon's former roommate Morgan Andrews filled in on bass guitar and other noises. It was this line-up that toured to support the new album, Blonder Tongue Audio Baton, and appeared in the video for its lead track, "Bell". Named for an obscure piece of vintage musical equipment, Blonder Tongue Audio Baton made use of Mellotron, Moog, and other analogue artifacts that the group had unearthed in the studio. During sequencing the band threw in numerous lo-fi compositions, soundbites, and rants, and collaged together an album jacket from arrays of found images and objects that matched the album's eclectic aesthetics. Hailed for melding "the high waters of shoegaze creativity and the mounting currents of indie rock", Blonder Tongue Audio Baton quickly rose to prominence in the American noise pop canon.
 Passage 2:Brock Pemberton (November 6, 1953 – February 17, 2016) was a Major League Baseball player, who played for the New York Mets in 1974 and 1975. He also played in the St. Louis Cardinals' organization. He played as a first baseman. Pemberton played high school baseball in Huntington Beach, California and was drafted by the Mets in the 6th round of the 1972 June Amateur Draft. After playing in the lower minor leagues in 1972 and 1973, he was promoted to AA level with the Victoria Toros of the Texas League in 1974. That year, he posted a .322 batting average in 134 games and 482 at bats for the Toros. He also had 8 home runs. This performance earned Pemberton a promotion to the Major League Mets late in the season. Pemberton made his debut with the Mets as a pinch hitter on September 10, 1974, against the Montreal Expos. The next day, the Mets and St. Louis Cardinals played a 25 inning game in which Pemberton got his first Major League hit, also as a pinch hitter. In all, he played 11 games for the Mets in 1974, with 4 hits in 22 at-bats and one run batted in. In four games as a first baseman he did not make an error.
 Passage 3:The 2002–03 season marked Watford Football Club's third consecutive season in the Football League First Division, following relegation from the Premier League in the 1999–2000 season. The club was managed by its former reserve team manager Ray Lewington, following the dismissal of Gianluca Vialli at the end of 2001–02. The club finished 13th in the First Division, reached the semi-final of the FA Cup, and were eliminated in the first round of the League Cup. Watford were operating under severe financial constraints following the collapse of ITV Digital, and at the end of the season were forced to offload several first team players, including Tommy Smith, Gifton Noel-Williams, Stephen Glass and the club's record signing at the time Allan Nielsen.
