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.

New input case for you: Question: Which organization that Robertson as a fellow of was founded first? Passage 1:In September she was part of the covering force for the Salerno landings, but by the end of the year had been transferred to the Bay of Biscay to carry out anti-blockade-runner patrols, as part of Operation Stonewall. However, she soon returned to the Mediterranean, this time for Operation Shingle, the Anzio landings, in January 1944. In June 1944 she covered the landings in Normandy as part of Force D off Sword Beach, then carried out offensive patrols of the Brittany coast in August to mop up the remnants of the German shipping in the area. Operating with destroyers, she sank Sperrbrecher 157 on 14/15 August and during the battle of Battle of Audierne Bay sank five Vorpostenboote on 22/23 August. After this she returned to the Home Fleet, covering the carrier raids along the Norwegian coast and making anti-shipping strikes. On the night of 27/28 January 1945, in company with the cruiser , she fought the Action of 28 January 1945 with German destroyers in which was badly damaged. Following this action she was refitted at Cammell-Laird's between February 1945 and March 1946.
 Passage 2:Robertson was born in Scotland, and attended King’s College in Auckland, New Zealand. where his father, the Scotsman, Charles Alexander Robertson had been Headmaster. After studying accountancy he went into business with Nello Porter and W. H Hemingway forming an accounting firm, publishing house and correspondence school specialising in accountancy and business courses. They later split the business, and following an expansion to Australia he set up permanently in Melbourne in 1913. Robertson built the Melbourne headquarters at Bank House in Bank Place, Collins Street and opened offices throughout Australia and later operations in North America and the United Kingdom. In Britain he was made Vice President of the Royal Institute of Commerce from 1929 to 1930, a Fellow of the Society of Incorporated Accountants and Auditors and a Fellow of the Royal Society of the Arts. Following his return to Australia, Robertson was embroiled in a landmark High Court tax case, which contested his income in Britain. Ironically, it was his close friend Justice Owen Dixon who fined Robertson, and arranged for him to help amend the loophole in the Commonwealth tax laws. Afterwards it is rumored Robertson was satirically made to play left-handed (his non-preferred) against Dixon in a round of golf, which being ambidextrous he still won. A keen speculator and prudent investor, Robertson had far reaching pecuniary interests and directorial roles in mining, wheat and wool, as well as educational links through his Hemingway Robertson Institute with the University of Melbourne. He was made president of the Stock Exchange of Melbourne from 1934 to 1936, managing the formation of the Australian Associated Stock Exchanges (AASE) which opened in 1937. In his later years and up until his death, Robertson was a Victorian representative, and first chairman of the Melbourne branch, of the Liberal Party of Australia, and a confidant of Robert Menzies. Robertson was an important figure in the 1949 Australian federal election, and defeat of Ben Chifley, where Menzies and the newly formed Liberal Party won power in a massive landslide, scoring a 48-seat swing—still the largest defeat of a sitting government at the federal level in Australia.
 Passage 3:Sachs joined the faculty at Case Western Reserve University in 1957 and was made a full professor in 1966. He left Case Western Reserve to become the section chief of neurochemistry at The Roche Institute of Molecular Biology. Through his research, Sachs discovered the relationship between neurophysin, an intracellular chaperone protein and vasopressin, the neurohormone that is critical for maintaining water balance in the body. He hypothesized that neurophysin and vasopressin are both part of a larger, inactive precursor protein, a prohormone, which is then enzymatically cleaved and processed within the secretory granule to produce and secrete both peptide products. Sachs' hypothesis preceded the discovery of proinsulin by 3 years, and his research laid the foundation for understanding the biosynthesis of all brain peptides and many proteins, which are major constituents involved in brain and neuroendocrine functions. Sachs showed that vasopressin was first synthesized as a prohormone in specialized nerve cells (called neurosecretory cells) in the hypothalamus and was then transported to the nerve terminals in the posterior pituitary where the vasopressin peptide was completely processed during axonal transport in secretory granules and ultimately secreted into the blood. He also showed that brain tissue could be kept intact and functional for two months in tissue culture, and contributed to the understanding of the interactions between the neuroendocrine neurons and neuroglial cells in the hypothalamal-neurohypophysial system (HNS).
