Part 1. Definition
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.
Part 2. 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.

Part 3. Exercise
Question: In what city or town was the French ornithologist who introduced the genus Vanga born in? Passage 1:In October 1991, Price left the group to perform solo production work, eventually forming his own label, Sun Text. The remaining members released a fourth album called Gorgeous, and after that, did some remix work for David Bowie, Soundgarden, and other performers, before returning with the album entitled Don Solaris in 1996. It featured contributions from James Dean Bradfield, who sung vocals on "Lopez", which reached number 20 in the UK Singles Chart. This song was remixed by Brian Eno. In 1997, they had remixed the Mansun track “Skin Up, Pin Up” for the Spawn soundtrack. The song "Bond" featured vocals by Mike Doughty from the band Soul Coughing and "Azura" featured Lou Rhodes from Lamb. They released a greatest hits compilation album,  in 1998. In 2000, Newbuild was re-released.
 Passage 2:Sub-nationally, the United Kingdom has three legal systems, each of which derives from a particular geographical area and for a variety of historical reasons: English law, Scots law, and Northern Ireland law. Since 2007, as a result of the passage of the Government of Wales Act 2006 by Parliament, there also exists purely Welsh law. However, unlike the other three laws, this is not a separate legal system per se, being merely the primary and secondary legislation generated by the National Assembly for Wales, interpreted in accordance with the doctrines of English law, and not impacting upon English common law (except where such Welsh legislation ousts a common law rule by virtue of being a superior form of law). There is a substantial overlap between these three legal systems, and the three legal jurisdictions of the United Kingdom, these being England and Wales, Scotland, and Northern Ireland. Each legal system defaults to each jurisdiction, and court systems of each jurisdiction further the relevant system of law through jurisprudence. In private law it's possible for people in certain jurisdictions to use the law of other jurisdictions, for example a company in Edinburgh, Scotland and a company in Belfast, Northern Ireland are free to contract in English law. This is inapplicable in public law (for example, criminal law), where there are set rules of procedure in each jurisdiction. Overarching these systems is the law of the United Kingdom, also known as United Kingdom law or (more rarely) British law. British law arises where laws apply to the United Kingdom and/or its citizens as a whole, most obviously constitutional law, but also other areas, for instance tax law. 
 Passage 3:In 1760 the French zoologist Mathurin Jacques Brisson included a description of the hook-billed vanga in his Ornithologie based on a specimen collected on the island of Madagascar. He used the French name L'écorcheur de Madagascar and the Latin Collurio Madagascariensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the hook-billed vanga. Linnaeus included a brief description, coined the binomial name Lanius curvirostris and cited Brisson's work. It is now the only species placed in the genus Vanga that was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1816. The specific name curvirostris is from Latin curvus "curved" and -rostrum "billed". The word "vanga" is the Malagasy name for the species. Two subspecies are recognised.
