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: How long had the civil war been underway when Gorges returned? Passage 1:His signature appears as a witness on a document dated 1629 claiming to be a deed for the sale of land by Indians to a group of settlers led by John Wheelwright on the south side of the Piscataqua River in what is now New Hampshire. This document was alleged to be a forgery by 19th century historian James Savage, based in part on evidence that Vines was in England at the time of the sale. In 1630 he was definitely involved in the establishment of settlements around Cape Elizabeth, Maine as part of Gorges' efforts to establish the proprietary Province of Maine. Gorges did not receive a royal charter for the land and a commission as governor until 1639, at which time Gorges appointed his cousin Thomas as deputy governor. Thomas Gorges established the government of the colony, and in 1642 he and Vines led an exploratory expedition into the interior that reached as far as the White Mountains. Gorges returned to England in 1643 to fight in the English Civil War. Government of the colony devolved to a council, which elected Vines deputy governor in 1644. Vines governed until 1645, during which time the colony was involved in conflicting land claims of the Lygonia territory administered by George Cleeve.
 Passage 2:Like the other princes of the imperial blood at the time, Prince Nashimoto Morimasa pursued a military career. Educated at the Central Military Preparatory School and the Imperial Japanese Army Academy, he received a commission as a second lieutenant in the IJA 39th Infantry Regiment in 1899. In 1903, he went to the École Spéciale Militaire de Saint-Cyr at St. Cyr, France, but returned to Japan the following year and served with his regiment as a captain under General Yasukata Oku in the Russo-Japanese War. Prince Nashimoto then returned to France in August 1906 and remained until July 1909. The Prince rose to the rank of major of the Infantry in 1906, lieutenant colonel in 1908, and colonel in 1910. He was promoted to lieutenant general and commander of the IJA 16th Division in August 1917.
 Passage 3:Born in Brighouse Farm Borgue near Kirkcudbright, Scotland, he arrived on Vancouver Island in 1860, where he helped to found the first sawmill in Port Alberni, British Columbia. On 24 July. 1863 he was made a justice of the peace for the Colony of Vancouver Island. When the sawmill burnt down in 1865, Sproat returned to England, but maintained his interest in the affairs of the colony, which was united with the mainland in 1866. Sproat's fascination with the First Nations people he encountered on Vancouver Island, led to his best remembered book, The Nootka:Scenes and studies of savage life, which appeared in 1868. In 1870 he wrote Education of the Rural Poor which argued for the extension of elementary education to all, including agricultural laborers. Following British Columbia's entry into Canadian Confederation in 1871, Sproat became the new province's agent general in London, a position he held from 1872 until his return to the province in 1876. Beginning in 1883, Sproat began travelling to the Interior of British Columbia, especially to the Kootenay region, where he held several regional offices. After 1898, Sproat returned to Victoria, where he spent the majority of his time writing. He died there on 4 June 1913. Sproat Lake and Sproat Lake Provincial Park on Vancouver Island are named in his honour by Robert Brown.
