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: What is the current population of the town where Benton first began to practice after completing the bar in 1835? Passage 1:Duchenne muscular dystrophy (DMD) is caused when a mutation in the dystrophin gene changes the RNA so that it no longer codes for functional dystrophin protein. This usually happens due to a mutation that alters the reading frame of the RNA downstream of the mutation, so-called frameshift mutation. If an exon with an appropriate number of bases lies near the mutation, removing that exon can correct the downstream reading frame, restoring the production of partially functional dystrophin. This is the general strategy used in the design of exon-skipping oligonucleotides for DMD. As there are 79 exons in the longest splice form of the dystrophin transcript, many different oligonucleotides are needed to address the range of mutations present in the population of people with DMD.
Passage 2:Born in Fryeburg, Oxford County, Maine, Benton was the son of Dr. Joseph and Catherine Benton and the brother of Nathaniel S. Benton. He pursued preparatory studies before moving to Herkimer County, New York in 1824 to live with an elder brother. Later, he attended Lowville Academy at Lowville, New York. Benton also learned the tanner's trade, but left the trade and became the editor of the Mohawk Courier and the Little Falls Gazette from 1830 to 1832. During that time he also studied law and was admitted to the bar in 1835 and commenced practice at Little Falls, New York. He married Emeline Fuller in 1840 and they had one son, Linn Boyd Benton (named for his colleague Linn Boyd), who became an inventor and engineer, and co-founded the printing company American Type Founders. Linn Benton's son (and Charles's grandson), Morris Fuller Benton, would become one of the most prolific American type designers of his era through his work for ATF. He married again in 1853 to Elizabeth B. Reynolds and they also had one son, Charles R. Benton.
Passage 3:In February 2009, the band toured Europe; a number of the U.K. dates were part of a package tour sponsored by Metal Hammer dubbed "Defenders of the Faith" featuring Dimmu Borgir as co-headliners. The group then toured Australia through March as part of the Soundwave Festival, which was headlined by Nine Inch Nails and Alice in Chains. In April 2009, the group began a headlining North American tour, sponsored by No Fear Energy. The leg began in Phoenix, Arizona and wrapped up mid-May in North Myrtle Beach, South Carolina. In July 2009, during a European summer tour, guitarist Mark Morton exited the tour prior to the final six dates as he and his wife were expecting their first child. Morton was replaced by Buz McGrath of Unearth for the remaining summer dates, and Doc Coyle of God Forbid for.the first three weeks of a fall North American leg. Morton eventually rejoined the group in October in Tampa, Florida.

Example Input: Question: How old was the British Admiral when he took control of the Southeast Asia Command? Passage 1:Silvanus was born in Gaul, the son of Bonitus, a Laetic Frankish general who had supported Constantine I in the civil war against Licinius. Like so many other Franks of his times, and like his father before him, he was a loyal and thoroughly romanized "barbarian" in the military service of the Empire. By AD 351, he held the rank of tribune and was one of the senior officers who defected to Emperor Constantius II at the Battle of Mursa Major, after initially supporting the usurper Magnentius. An able soldier, Silvanus was eventually promoted to the rank of Magister militum per Gallias, a crucial post, then in AD 352-353, Constantius personally entrusted him with the difficult task of driving the Alamanni tribesmen raiding and looting in Gaul back beyond the Rhine, and restoring the fast eroding Roman authority in the province. This Silvanus fulfilled partly by bribing the Alamanni chieftains with the taxes he had collected, partly by defeating the Alamanni in battle and partly by suppressing the local bagaudae insurrections flaring up again in central and northern Gaul.
Passage 2:At the Potsdam Conference in July 1945, the Combined Chiefs of Staff decided that Indochina south of latitude 16 north was to be included in the Southeast Asia Command under British Admiral Mountbatten. Japanese forces located south of that line surrendered to him and those to the north surrendered to Generalissimo Chiang Kai-shek. In September 1945, Chinese forces entered Tonkin, and a small British task force landed at Saigon. The Chinese accepted the Vietnamese government under Ho Chi Minh, then in power in Hanoi. The British refused to do likewise in Saigon, and deferred to the French there from the outset, against the ostensible support of the Viet Minh authorities by American OSS representatives. On V-J Day, September 2, Ho Chi Minh had proclaimed in Hanoi the establishment of the Democratic Republic of Vietnam (DRV). The DRV ruled as the only civil government in all of Vietnam for a period of about 20 days, after the abdication of Emperor Bao ai, who had governed under Japanese rule. On 23 September 1945, with the knowledge of the British commander in Saigon, French forces overthrew the local DRV government, and declared French authority restored in Cochinchina. Guerrilla warfare began around Saigon immediately, but the French gradually retook control of the South and North of Indochina. Ho Chi Minh agreed to negotiate the future status of Vietnam, but the talks, held in France, failed to produce a solution. After over one year of latent conflict, all-out war broke out in December 1946 between French and Viet Minh forces as Ho Chi Minh and his government went underground. The French tried to stabilize Indochina by reorganizing it as a Federation of Associated States. In 1949, they put former Emperor Bao ai back in power, as the ruler of a newly established State of Vietnam.
Passage 3:Like the star Epsilon Draconis in the constellation of Draco, Beta Cephei is visible primarily in the northern hemisphere, given its extreme northern declination of 70 degrees and 34 minutes. It is nevertheless visible to most observers throughout the world reaching as far south as cities like Harare in Zimbabwe, Santa Cruz de la Sierra in Bolivia or other settlements north 19South latitude. It is circumpolar throughout all of Europe, northern Asia, and North American cities as far south as Guadalajara in west central Mexico. All other locations around the globe having a latitude greater than 20North will notice that the star is always visible in the night sky. Because Beta Cephei is a faint third magnitude star, it may be difficult to identify in most light polluted cities, though in rural locations the star should be easily observable.

Example Input: Question: In the 1909 novel written by Barclay, what is the name of the main character? Passage 1:In 1881, Florence Charlesworth married the Rev. Charles W. Barclay and honeymooned in the Holy Land, where, in Shechem, they reportedly discovered Jacob's Well, the place where, according to the Gospel of St John, Jesus met the woman of Samaria (). Florence Barclay and her husband settled in Hertford Heath, in Hertfordshire, where she fulfilled the duties of a rector's wife. She became the mother of eight children. In her early forties health problems left her bedridden for a time and she passed the hours by writing what became her first romance novel titled The Wheels of Time. Her next novel, The Rosary, a story of undying love, was published in 1909 and its success eventually resulted in its being translated into eight languages and made into five motion pictures, also in several languages. According to the New York Times, the novel was the No.1 bestselling novel of 1910 in the United States. The enduring popularity of the book was such that more than twenty-five years later, Sunday Circle magazine serialized the story and in 1926 the prominent French playwright Alexandre Bisson adapted the book as a three-act play for the Parisian stage.
Passage 2:After the D-Day invasion, was reassigned to IX Tactical Air Command (IX TAC) and directed to provide ground support for advancing United States First Army forces in France, attacking enemy targets initially in the Cotentin Peninsula, then supported Operation Cobra, the breakout of Normandy and attacked enemy forces in the Falaise-Argentan Gap. Wing headquarters and subordinate units operated primarily from liberated airfields and newly built temporary Advanced Landing Grounds in France, moved into north-central France, its groups attacking enemy targets near Paris then north-west into Belgium and the southern Netherlands. In December 1944/January 1945, engaged enemy targets on the north side of the Battle of the Bulge, then moved eastward into the Northern Rhineland as part of the Western Allied invasion of Germany.
Passage 3:The source of all daylight is the Sun. The proportion of direct to diffuse light impacts the amount and quality of daylight. "Direct sunlight" reaches a site without being scattered within Earth's atmosphere. Light that is scattered in the atmosphere is diffused daylight. Ground reflected light also contributes to the daylight. Each climate has different composition of these daylights and different cloud coverage, so daylighting strategies vary with site locations and climates. There is no direct sunlight on the polar-side wall (north-facing wall in the Northern Hemisphere and south-facing wall in the Southern Hemisphere) of a building from the autumnal equinox to the spring equinox at latitudes north of the Tropic of Cancer and south of the Tropic of Capricorn.
