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: What year did the Sacco and Vanzetti case occur? Passage 1:In 1962, when only 14, he was fascinated by the success of the Arab national and anti-colonial forces that defeated the French colonial armies in the Algerian War, gaining independence for their country. When attending a military college in Kętrzyn (Ger. Rastenburg) in 1966-1969, he actively opposed the Polish communist regime during the 1968 Polish political crisis, and as a result was expelled from the Officer School, and became a political prisoner for the first time. He continued his studies at the University of Silesia in Katowice, and after graduation was employed there as a lecturer,adiunct and researcher. In 1980-81, when Poland was swept by a wave of anti-communist strikes, and around ten million joined the anti-communist Solidarity trade union, Kopański co-founded a branch of this broad grassroots social movement at the University of Silesia.
 Passage 2:Included in the BPL's research collection are more than 1.7 million rare books and manuscripts. It possesses wide-ranging and important holdings, including medieval manuscripts and incunabula, early editions of William Shakespeare (among which are a number of Shakespeare quartos and the First Folio), the George Ticknor collection of Spanish literature, a major collection of Daniel Defoe, records of colonial Boston, the 3,800 volume personal library of John Adams, the mathematical and astronomical library of Nathaniel Bowditch, important manuscript archives on abolitionism, including the papers of William Lloyd Garrison, and a major collection of materials on the Sacco and Vanzetti case. There are large collections of prints, photographs, postcards, and maps. The library, for example, holds one of the major collections of watercolors and drawings by Thomas Rowlandson. The library has a special strength in music, and holds the archives of the Handel and Haydn Society, scores from the estate of Serge Koussevitzky, and the papers of the important American composer Walter Piston.
 Passage 3:The policy change faced legal challenges. Following a challenge in the U.S. District Court for the District of Columbia, on October 30, 2017, Judge Colleen Kollar-Kotelly blocked enforcement of the ban, writing that as far as could be seen, "all of the reasons proffered by the president for excluding transgender individuals from the military in this case were not merely unsupported, but were actually contradicted by the studies, conclusions and judgment of the military itself". In March 2018, Trump announced a new policy on transgender service members, namely a ban on those with a diagnosis of gender dysphoria, which would effectively be a ban on most transgender service members. The new policy was challenged in the U.S. District Court for the Western District of Washington. On April 13, 2018 Judge Marsha J. Pechman blocked enforcement of the policy, ruling that the administration's updated policy essentially repeated the same issues as its predecessor order from 2017, and that transgender service members (and transgender individuals as a class) were a protected class entitled to strict scrutiny of adverse laws (or at worst, a quasi-suspect class), and ordered that matter continue to a full trial hearing on the legality of the proposed policy. On January 21, 2019, the Supreme Court — with Chief Justice John Roberts and Justices Samuel Alito, Neil Gorsuch, Brett Kavanaugh and Clarence Thomas forming the majority for the 5-4 opinion — allowed Trump's policy to go into effect while challenges in lower courts are adjudicated. On March 12, 2019, acting Deputy Defense Secretary David Norquist signed a directive to allow Trump's policy to take effect in 30 days.
