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 Input: Question: When did the state entitiy where Sakic was born dissolve?  Passage 1:Retford's officially designated BBC Local Radio station in terms of radio coverage is BBC Radio Sheffield. However, editorially, local news coverage is covered on BBC Radio Nottingham's radio and Internet outlets, despite Retford being outside the official coverage area of both BBC Radio Nottingham's FM and DAB signals. Trax FM also editorially covers the town of Retford, although its Ofcom designated FM coverage area only covers the Doncaster area, Worksop and rural areas west of Retford, Retford is covered on DAB via the Sheffield multiplex. Hallam FM's and Greatest Hits South Yorkshire's AM signals also cover the town of Retford. National analogue FM radio services from the BBC and Classic FM are broadcast from the Holme Moss transmitting station in West Yorkshire. Digital Radio services come primarily from the Clarborough transmitter outside of Retford for the Sheffield and Digital One multiplexes, Clifton transmitter near Doncaster for the BBC National DAB multiplex and the Belmont, High Hunsley (near Hull) and Tapton Hill (Sheffield), Waltham and Emley Moor transmitters for the Sound Digital multiplex.
 Passage 2:Dinko Šakić (8 September 1921 – 20 July 2008) was a Croatian fascist leader and war criminal who commanded the Jasenovac concentration camp in the Independent State of Croatia (NDH) from April to November 1944, during World War II. Born in the village of Studenci, near the town of Imotski in what was then the Kingdom of Serbs, Croats and Slovenes, he became a member of the fascist Ustaše at a young age. When the Axis powers occupied the Kingdom of Yugoslavia in April 1941, Šakić, aged 19, joined the administration in Jasenovac. He became the camp's assistant commander the following year, and married Nada Luburić, the half-sister of concentration camp commander Vjekoslav "Maks" Luburić, in 1943. This marriage, as well as his fanatic support for Ustaše leader Ante Pavelić, led to Šakić's appointment as commander of Jasenovac in April 1944. He was charged in the deaths of an estimated 2,000 people who died during his six months of command at the concentration camp.
 Passage 3:The Mustang's success left General Motors unprepared. Chrysler introduced the Plymouth Barracuda a few weeks before the Mustang, and although it was later redesigned as a distinct "pony car", it was initially a modified Plymouth Valiant. However, the "fish car" did not enjoy as strong a market demand as Ford's "pony". General Motors executives thought the rear-engined Chevrolet Corvair Monza would compete against the Mustang, but it also sold poorly by comparison. The Monza performed well, but lacked a V8 engine and its reputation was tarnished by Ralph Nader in his book Unsafe At Any Speed. It took GM until the 1967 model year to counter with the Chevrolet Camaro and Pontiac Firebird. Lincoln-Mercury joined the competition in 1966 with the Mercury Cougar, an "upmarket Mustang" and subsequent Motor Trend Car of the Year. In 1967, American Motors (AMC) introduced the Javelin, an image changing "standout" four-place pony car. In 1969, the Dodge Challenger, a version of the Plymouth Barracuda platform, was last to join the pony car race. This genre of small, sporty automobiles is often referred to as the "pony car" because of the Ford Mustang that established this market segment.

Example Input: Question: Which of the actors playing Qatermass and Paterson was younger? Passage 1:Born in Philadelphia, Day studied at the Jacobs School of Music at Indiana University and at the Curtis Institute of Music where she was a pupil of Margaret Harshaw. She placed third in the finals of the Metropolitan Opera National Council Auditions in 1973, which led to her debut performance at the Metropolitan Opera House on March 25, 1973 singing "Come scoglio" from Così fan tutte and "Song to the Moon" from Rusalka. She made her professional opera debut in 1972 with the Pennsylvania Opera Company as Violetta in La traviata. That same year she was the soprano soloist in Verdi's Requiem with the Mendelssohn Club. In 1973 she portrayed Mimi in La bohème and Violetta with the Little Lyric Opera Company in Philadelphia. In 1974 she made her debut with the Philadelphia Lyric Opera Company as Nella in Gianni Schicchi.
 Passage 2:Actor Jason Flemyng was cast as Quatermass, with long-time Kneale admirer Mark Gatiss as Paterson, Andrew Tiernan as Carroon, Indira Varma as his wife Judith, David Tennant as Briscoe, Adrian Bower as Fullalove and Adrian Dunbar as Lomax—now a Ministry of Defence official rather than a policeman. Isla Blair was cast as Home Secretary Margaret Blaker, a combination of parts of Lomax's character and two officials from the original serial, and she brought to rehearsals a photograph of her husband Julian Glover on the set of the 1967 film version of Quatermass and the Pit. Blair stated that she was delighted to be joining "the Quatermass club".
 Passage 3:The conflict emerged from the First Indochina War against the communist-led Viet Minh. Most of the funding for the French war effort was provided by the U.S. After the French quit Indochina in 1954, the US assumed financial and military support for the South Vietnamese state. The Việt Cộng, also known as or NLF (the National Liberation Front), a South Vietnamese common front under the direction of North Vietnam, initiated a guerrilla war in the south. North Vietnam had also invaded Laos in the mid-1950s in support of insurgents, establishing the Ho Chi Minh Trail to supply and reinforce the Việt Cộng. U.S. involvement escalated under President John F. Kennedy through the MAAG program from just under a thousand military advisors in 1959 to 16,000 in 1963. By 1963, the North Vietnamese had sent 40,000 soldiers to fight in South Vietnam. North Vietnam was heavily backed by the USSR and the People's Republic of China. China also sent hundreds of PLA servicemen to North Vietnam to serve in air-defense and support roles.

Example Input: Question: Is the racecourse where Roaring Riva began his racing career at and the location where he moved up in class for Group 1 Phoenix Stakes located in the same country? Passage 1:Emanuel Nobel was a very forward-looking businessman, just like his father, who had instigated the construction of Russia's first pipeline and the world's first oil tanker in 1878, as well as the world's first railway tank cars in 1883. On 16 February 1898 Emanuel signed a licence agreement in Berlin with Rudolf Diesel, after having heard Diesel describing his new engine in a public lecture. The agreement allowed Nobel to build the world's first diesel engine plant in St Petersburg, and the engines were used to propel Branobel's fleet of oil tankers. Emanuel led Baku to a dominating role in the global oil industry and Branobel activities soon developed throughout the Caspian Sea, operating also in Grozny and Dosser.
 Passage 2:Dean Clark took over as head coach shortly after James' resignation, and led the 1997–98 Hitmen to a remarkable turnaround. The team improved to a 40–28–4 record and first-place finish in the Central Division, qualifying for the playoffs for the first time in franchise history. They defeated the Saskatoon Blades and Swift Current Broncos to reach the Eastern Conference final before falling to the Brandon Wheat Kings. Clark was awarded the Dunc McCallum Memorial Trophy as the WHL's top coach, and also won the Canadian Hockey League's Brian Kilrea Coach of the Year Award. Calgary improved to 51–13–8 in 1998–99, finishing one point ahead of the Kamloops Blazers for the regular season title. Led by Brad Moran, Pavel Brendl and goaltender Alexandre Fomitchev, the Hitmen lost just five games in the playoffs en route to their first league championship. They won the title at home before a WHL playoff record crowd of 17,139. They became the first Calgary-based team to qualify for the Memorial Cup since the Calgary Canadians won the 1926 title.
 Passage 3:Roaring Riva began his racing career by winning a maiden race over five furlongs at Windsor Racecourse and then followed up by taking a minor event over six furlongs at the same track. In early July he was sent to York Racecourse to contest the Black Duck Stakes and finished second, beaten half a length by Nomination, a colt who went on to beat Green Desert in the Richmond Stakes. The colt was then sent to Ireland and moved up in class for the Group 1 Phoenix Stakes over six furlongs on soft ground at Phoenix Park Racecourse. Ridden by Ray Cochrane he started the 4/1 second favourite behind the highly regarded, but previously unraced Tate Gallery, with the best-fancied of the other eleven runners being the unbeaten filly Sherkraine, Devil's Run and Mr John. Roaring Riva was among the leaders from the start, went to the front two furlongs out and held off the challenge of the filly So Directed to win by three quarters of a length. Laing recalled that it was "quite a day. We had private planes, champagne, the lot!"
