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: In what country did Harrison earn an MSc in plant pathology? Passage 1:M48s were also used with mixed results during the Six-Day War of 1967. On the Sinai battlefront, Israeli M48s upgunned with the then-advanced 105 mm L7 rifled tank gun were used with considerable success against Egyptian IS-3s, T-54s/T-55s, T-34/85s and SU-100s supplied by the Soviet Union during the 1950s and the 1960s (such as during the Second Battle of Abu-Ageila. However, on the West Bank war-front, Jordanian M48s (Jordan was also a user of the M48 Patton as was Israel at the same time-period) were often defeated by Israeli 105mm-armed Centurions and WWII-era upgraded M4 Shermans (M-51s upgunned with French-built 105 mm tank guns (not to be confused with the British L7 105mm tank gun)). In purely-technical terms, the Pattons were far superior to the much-older Shermans, with shots at more than 1,000 meters simply glancing off the M48's armor. However, the 105 mm main gun of the Israeli Shermans fired a HEAT round designed to defeat the Soviet T-62 tank, which was the USSR's response to the M48's successor in US service, the M60 Patton. The Jordanian Pattons' general failure on the West Bank could also be attributed to excellent Israeli air superiority. The Israeli Army captured about 100 Jordanian M48 and M48A1 tanks and pressed them into service in their own units after the war, as the same as were the Jordanian M113 APCs they seized during the war.
 Passage 2:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.
 Passage 3:On the song "The Kid Frankie", Khalifa raps over the English R&B band Loose Ends' No. 1 hit single, "Hangin' on a String" (1985). Khalifa stated that the song was inspired by the character Frankie from the film The Business (2005), who listens to Loose Ends while traveling around Spain. The song "Never Been" samples "Schala's Theme" from the soundtrack to the video game Chrono Trigger with its soundtrack composed by Yasunori Mitsuda. The song "Up", samples Tevin Campbell's "Could It Be". "In the Cut" samples "Let Go" by Frou Frou from the end credits of the film Garden State, the song "We're Done" samples the single "Our Time Is Here" by Demi Lovato from the Disney soundtrack Camp Rock. The song "Visions" contains a sample from "Huit Octobre 1971" by Cortex. "Spotlight" sampled "Theme from the Planets" by Dexter Wansel, from his album "Life on Mars" (1976) and "Still Blazin" samples Alborosie's song of the same name.
