Given the task definition, example input & output, solve the new input case.
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.

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

New input case for you: Question: Of the three people Asleep at the Wheel collaborated with in 2015, what is the birth date of the oldest? Passage 1:Pol became the second wife of John Paul Getty, Jr. on 10 December 1966. She was married in a white miniskirt, trimmed with mink. The Gettys became part of Swinging London's fashionable scene, becoming friends with, among others, singers Mick Jagger of the Rolling Stones and his girl-friend Marianne Faithfull. Faithfull has recounted her apprehension, through "ingrained agoraphobia", about an invitation to spend five weeks with the Gettys in Morocco ("but for Mick this is an essential part of his life") and how, after splitting from Jagger, she took up with Talitha Getty's lover, Count Jean de Breteuil, a young French aristocrat (1949–1971). Breteuil supplied drugs to musicians such as Jim Morrison of The Doors, Keith Richards, and Marianne Faithfull, who wrote that Breteuil "saw himself as dealer to the stars" and has claimed that he delivered the drugs that accidentally killed Morrison less than two weeks before Talitha's own death in 1971. For his part, Richards recalled that John Paul and Talitha Getty "had the best and finest opium".
 Passage 2:The seven athletes that were selected to compete in the London Games were Gerald Phiri in the men's 100 metres, Prince Mumba in the men's 800 metres and Chauzje Choosha in the women's 100 metres. Choosha qualified via a wildcard and replaced long-distance runner Tonny Wamulwa, who withdrew before the opening of the Games because of injuries sustained in a road traffic accident on 9 July. Swimmers Zane Jordan and Jade Ashleigh Howard qualified for the Games via a universality place awarded by FINA as their best times of 59.33 and one minute and 1.24 seconds were not within the standard entry time. Judo Boas Munyonga qualified for the men's 81 kg event after being awarded an additional place in the additional places category for the African continent by the International Judo Federation. Boxer Gilbert Choombe qualified for the men's light welterweight following the conclusion of the AIBA African Olympic Qualifying Event.
 Passage 3:And in any case, people in Texas came to identify with the song. The work of the Austin-based group Asleep at the Wheel helped to keep popular knowledge of Wills going, and they collaborated with Clint Black on a new version of "Bob Wills Is Still the King" on a 1999 tribute album Ride With Bob. Another recording of the song by Asleep at the Wheel, this time in collaboration with Waylon's son Shooter Jennings together with Randy Rogers and Reckless Kelly, appeared on the 2015 effort . The song itself is collected on several Jennings live sets, compilations, and box sets, including RCA Country Legends (2001 compilation, includes studio version),  Live from Austin, TX (recorded 1989, released 2006), and Nashville Rebel (2006 box set including studio version). Perhaps the most unexpected appearance was a performance by The Rolling Stones in Austin in 2006 during their A Bigger Bang Tour. Their arrangement featuring Ronnie Wood playing pedal steel guitar was captured on their 2007 The Biggest Bang concert DVD release.
