Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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.

Solution: 1
Reason: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this instance: Question: When was the library who now own the detailed estates survey drawn by J W Poundley first open? Passage 1:In the Middle Ages Cilthriew was one of the townships in Kerry. The township is also referred to as Kilroith or Kilroyth. Richard Williams makes the claim that Cilthriew and the neighbouring house of Brynllywarch (which was also a township) were in the ownership of the Pugh (ap Hugh) family from at least 1500. A William Pugh of Kilroith is mentioned in 1632, when he purchased from Ann Foxe, widow of Somerset Foxe lands in Kilroith including Maes y Deynant William Pugh of ‘‘Kilthrew’’ was the Sheriff of Montgomeryshire in 1767 and his son William, who was also Sheriff of Montgomeryshire in 1813, became a very successful attorney and purchased the Caer Howell estate in Montgomery. His son was the notable William Pugh, an entrepreneur, who did much to develop trade and infrastructure in the Montgomeryshire Severn valley. He paid for the final extension of the Montgomery Canal from Berriew to Newtown, and for various road building schemes including a road from Abermule along the Mule valley. In Newtown he encouraged the growth of the textile industry and was responsible for the Flannel exchange, designed by Thomas Penson. In 1828 he sold the Caer Howell estate, using the proceeds to develop Brynllywarch. For this work he may have employed T G Newnham and J W Poundley as his architects and surveyors. His schemes were over ambitious and in June 1835 he fled to Caen in Normandy to escape his creditors. This resulted in the Brynllywarch and Cilthriew estates, which then consisted of 27 farms, being sold in 1839 to Richard Leyland (Bullin), a very wealthy banker from Liverpool. Leyland was to give these estates, together with the Leighton Hall Estates to his nephew John Naylor in 1846. The very detailed survey of the estates purchased by Leyland and later John Naylor, drawn up by J W Poundley, is now in the National Library of Wales. John Naylor died on13th July 1889 and the estates continued in the Naylor family ownership until about 1930, when the various farms including Cilthriew were sold.
 Passage 2:Cameron was born at Glasgow and received his early education in his native city. After having taught Greek in the university for twelve months, he removed to Bordeaux, where he was soon appointed a regent in the college of Bergerac. He did not remain long at Bordeaux, but accepted the offer of a chair of philosophy at the Academy of Sedan, where he passed two years. He then returned to Bordeaux, and in the beginning of 1604 he was nominated one of the students of divinity who were maintained, at the expense of the church, and who for the period of four years were at liberty to prosecute their studies in any Protestant seminary. During this period he acted as tutor to the two sons of the chancellor of Navarre. They spent one year at Paris, and two at Geneva, whence they removed to Heidelberg. In this university, on 4 April 1608, he gave a public proof of his ability by maintaining a series of theses, De triplici Dei cum Homine Foedere, which were printed among his works. The same year he was recalled to Bordeaux, where he was appointed the colleague of Dr Gilbert Primrose; and when Francis Gomarus was removed to Leiden, Cameron, in 1618, was appointed professor of divinity at the Academy of Saumur, the principal seminary of the French Protestants. 
 Passage 3:For the next three hundred years, Scotland was directly governed by the Parliament of Great Britain and the subsequent Parliament of the United Kingdom, both seated at Westminster, and the lack of a Parliament of Scotland remained an important element in Scottish national identity. Suggestions for a 'devolved' Parliament were made before 1914, but were shelved due to the outbreak of the First World War. A sharp rise in nationalism in Scotland during the late 1960s fuelled demands for some form of home rule or complete independence, and in 1969 prompted the incumbent Labour government of Harold Wilson to set up the Kilbrandon Commission to consider the British constitution. One of the principal objectives of the commission was to examine ways of enabling more self-government for Scotland, within the unitary state of the United Kingdom. Kilbrandon published his report in 1973 recommending the establishment of a directly elected Scottish Assembly to legislate for the majority of domestic Scottish affairs.
