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 input: 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.

Q: Question: What is the main characteristic of the feature bromus ciliatus does not have? Passage 1:Bromus ciliatus is a perennial grass that grows in tufts up to tall, and occasionally taller in the Great Plains. The grass lacks rhizomes but has a well developed root system. The sheaths are glabrous or bear minute hairs and have a narrow "V" shaped orifice. The sheaths are typically shorter than the internodes. The scabrous leaves often have sparse long hairs and measure wide. The open inflorescence bears many spikelets on stalks, the upper ones ascending and the lower nodding or drooping. This panicle is long. The flattened spikelets are long and wide. The spikelets are greenish and occasionally tinged with bronze or purple. The spikelets bear three to nine flowers and display their rachilla at maturity. The glumes are conduplicate, with the upper glume tapering at its base. The firm lemmas are also conduplicate, measuring broad with delicate nerves. The linear palea is typically enclosed by the folded lemma. The anthers are long. The caryopsis is lanceolate in shape.
Passage 2:After his graduation, he was elected as the chief judge of Ascoli, but he then settled in his native town, where he filled various responsible offices. Both father and son belonged to a confraternity suspected of meeting for the discussion of opinions hostile to the Roman church. The Inquisition was upon the track of the heretics, and Gentili, together with his father and one of his brothers, Scipione Gentili, were forced to leave Italy because of their Protestant beliefs. The three first went to Ljubljana (German: Laibach), now in Slovenia, the capital of the duchy of Carniola. From there, Alberico went on to the German university towns of Tubingen and Heidelberg. At their first halting place, Ljubljana, Matteo, doubtless through the influence of his brother-in-law, Nicolo Petrelli, a jurist high in favour with the court, was appointed chief physician for the duchy of Carniola. In the meantime, the papal authorities had excommunicated the fugitives and soon procured their expulsion from Austrian territory. Early in 1580, Alberico set out for England, preceded by a reputation that procured him offers of professorships at Heidelberg and at Tubingen, where Scipio was left to commence his university studies. Alberico reached London in August, with introductions to Giovanni Battista Castiglione, the Italian tutor to Queen Elizabeth I. Gentili soon became acquainted with Dr Tobia Matthew, the Archbishop of York. On 14 January 1581, Gentili was accordingly incorporated from Perugia as a D.C.L. giving Gentili the right of teaching law, which he first exercised in St John's College, Oxford. Subsequently, Gentili was appointed as the Regius professor of civil law at Oxford University by the Chancellor of Oxford University, Robert Dudley, 1st Earl of Leicester. He was commissioned to prepare a revised version of the statutory laws of his home town, a task which he completed in 1577. After a short stay in Wittenberg, Germany, he returned to Oxford.
Passage 3:On 1 May 1932, Stahlecker joined the Nazi Party (no. 3,219,015) as well as the SS (no. 73,041). On 29 May 1933, he was appointed deputy director of the Political Office of the Wurttemberg State Police. In 1934, he was appointed head of the Gestapo in the German state of Wurttemberg and soon assigned to the main office of the Sicherheitsdienst (SD). On 11 May 1937, he became head of the Gestapo in Breslau. After the incorporation of Austria in 1938, Stahlecker became SD chief of the Danube district (Vienna), a post he retained even after being promoted to SS-Standartenfuhrer. In the summer of 1938, Stahlecker became Inspector of the Security Police in Austria, succeeding Gestapo chief Heinrich Muller in that position. As of 20 August 1938, Stahlecker was the formal head of the Central Agency for Jewish Emigration in Vienna, though its de facto leader was Adolf Eichmann. Differences of opinion with Reinhard Heydrich motivated Stahlecker to move to the Auswartiges Amt (Foreign Office), after which he held posts as the commander of the Security Police and SD in the Protectorate of Bohemia and Moravia under SS-Brigadefuhrer Karl Hermann Frank. In mid-October 1939, Eichmann and Stahlecker decided to begin implementation of the Nisko Plan.
