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.
One example is below.
Q: 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.

Rationale: The question refers to the 704th unit and task about war which is decribed by Passage 1.
Q: Question: When was Cohen born? Passage 1:Collard made his debut for Cambridgeshire in the 1971 Minor Counties Championship against Bedfordshire. Collard played Minor counties cricket for Cambridgeshire from 1971 to 1992, including 108 Minor Counties Championship matches and 14 MCCA Knockout Trophy matches. In 1975, he made his List A debut against Northamptonshire in the Gillette Cup. He played four further List A matches for Cambridgeshire, the last coming against Worcestershire in the 1989 NatWest Trophy. In his five List A matches, he scored 17 runs at a batting average of 8.50, with a high score of 9. With the ball he took 5 wickets at a bowling average of 33.20, with best figures of 3/38.
 Passage 2:When the ultimate goal of plasma processing is a purified plasma component for injection or transfusion, the plasma component must be highly pure. The first practical large-scale method of blood plasma fractionation was developed by Edwin J. Cohn during World War II. It is known as the Cohn process (or Cohn method). This process is also known as cold ethanol fractionation as it involves gradually increasing the concentration of ethanol in the solution at 5C and 3C. The Cohn Process exploits differences in properties of the various plasma proteins, specifically, the high solubility and low pI of albumin. As the ethanol concentration is increased in stages from 0% to 40% the [pH] is lowered from neutral (pH ~ 7) to about 4.8, which is near the pI of albumin. At each stage certain proteins are precipitated out of the solution and removed. The final precipitate is purified albumin. Several variations to this process exist, including an adapted method by Nitschmann and Kistler that uses fewer steps and replaces centrifugation and bulk freezing with filtration and diafiltration.
 Passage 3:Roger Brito is listed in the Domesday Book of 1086 as holding land under the overlordship of the Church of Long Sutton in Somerset, in which county the family was later seated at Sampford Brett (alias Sandford-Bret). During the reign of King Henry I (1100–1135) Sampford Brett was held by Simon le Bret, from the feudal barony of Dunster by military service of half a knight's fee. He served in the household of Henry II's brother William, Count of Poitou and was a near neighbour of the FitzUrse family of Williton in Somerset, a member of which family was another of the assassins of Thomas Becket. Simon le Bret had two sons: Richard Brito, one of the assassins of Thomas Becket and Edmund le Bret, who adopted the surname de Sandford from his seat. William the Conqueror granted a manor in the eastern part of the parish of Great Stamford Bridge in Essex and another in Sanford in Somerset to a Norman named Auvrai Le Breton following the Norman conquest of England. A later relative, Simon Le Breton, had two sons, Richard and Edmund, who inherited their share of Sanford and Great Master Bridge. Both were part of the royal court of King Henry II; in particular Richard Le Breton was a close friend of the king's brother, Prince William.
