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-Lo 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 (18941973) 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: What is Rubus fruticosus? Passage 1:At the Drive-In frontman Cedric Bixler-Zavala stated that "there would be no Relationship of Command without Drive Like Jehu." He declared: "I remember doing a lot of English press and people being like, 'We think you guys are exotic, the names of the songs and flannel and look is exotic.' I definitely knew what school we came from, and that people like Hot Snakes and Drive Like Jehu were our strongest influences, but they weren't exactly huge in Europe." Isaac Brock of the indie rock band Modest Mouse said in 2007: "I love [Drive Like] Jehu. Jehu is one of my favorite all-time bands actually." Deftones covered their song "Caress" on their 2011 cover album. Brian Cook, bassist for the metalcore band Botch, stated that "Drive Like Jehu was a huge influence on Botch; their writing approach definitely mirrored what we did in terms of banging things out till we had a song." British hardcore punk group Gallows were also inspired by them and Laurent Barnard singled out John Reis as one of his five favorite guitarists. The Blood Brothers vocalist Jordan Blilie described Rick Froberg's lyrics in the band as "equal parts perplexing and relatable" and called his voice "one of my all-time favorites". He added that the early guitar playing of his own group can be mostly traced back to Jehu. Other artists who have cited them as an influence or expressed admiration for their work are Thursday, Jim Adkins of Jimmy Eat World, Justin Pearson of The Locust, Ben Weinman of The Dillinger Escape Plan, Violent Soho, Unbroken, Akimbo and Sandrider, KEN Mode, METZ, Matthew Bajda of Funeral Diner, Bryan Giles of Red Fang, Steven Roche of Off Minor and Genghis Tron.
Passage 2:Most of the islands have dense cover of bramble Rubus fruticosus and bracken Pteridium aquilinum and grassland along the coastal fringes. Goldenrod (Solidago virgaurea) is locally abundant amongst the heath communities growing on the podzolic soils on the higher parts of the islands. The heaths are classified as a poor fit somewhere between H10 and H11 and the heather (Calluna vulgaris), bell heather (Erica cinerea) and bracken merge into pure bracken on the lower slopes. A feasibility study is needed to decide if the vegetation would benefit from grazing through a Higher Level Stewardship (HLS) agreement. With no resident botanist, together with the difficulty of recording on remote islands, there are not many plant records and the number of species for each of the Eastern Isles was finally published in 1971 from surveys carried out by J D Grose, Mr & Mrs J E Dallas and J E Lousley in 1938 and 1939. Lousley listed 111 species of higher plants in his 1971 Flora, and by 1999 further surveys recorded a similar number (114). Some of the islands have species that are only found on that island and not on the other Eastern Isles such as an oak tree found by Mr and Mrs Dallas on Great Gannick. Possible ancient woodland indicators such as butcher's-broom (Ruscus aculeatus), wood spurge (Euphorbia amygdaloides) and wood small-reed (Calamagrostis epigejos) have also been recorded on Great Gannick. The nationally rare orange bird's-foot (Ornithopus pinnatus) is found on the northern side of Great Ganilly.
Passage 3:Although Pilate is the best-attested governor of Judaea, few sources on his rule have survived. He appears to have belonged to the well-attested Pontii family, but nothing is known for certain about his life before he became governor of Judaea, nor of the circumstances that led to his appointment to the governorship. A single inscription from Pilate's governorship has survived, the so-called Pilate stone, as have coins that he minted. The Jewish historian Josephus and philosopher Philo of Alexandria both mention incidents of tension and violence between the Jewish population and Pilate's administration. Many of these involve Pilate acting in ways that offended the religious sensibilities of the Jews. The Christian Gospels record that Pilate ordered the crucifixion of Jesus at some point during his time in office; Josephus and the Roman historian Tacitus also appear to have recorded this information. According to Josephus, Pilate's removal from office occurred because he violently suppressed an armed Samaritan movement at Mount Gerizim. He was sent back to Rome by the legate of Syria to answer for this before Tiberius, who, however, had died before he arrived. Nothing is known for certain about what happened to him after this. On the basis of a mention in the second-century pagan philosopher Celsus and Christian apologist Origen, most modern historians believe that Pilate simply retired after his dismissal. Modern historians have differing assessments of Pilate as an effective ruler; while some believe he was a particularly brutal and ineffective governor, others argue that his long time in office means he must have been reasonably competent. According to one prominent post-war theory, Pilate was motivated by antisemitism in his treatment of the Jews, but this theory has been mostly abandoned.
