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.
One example is below.
Q: 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.

Rationale: The question refers to the 704th unit and task about war which is decribed by Passage 1.
Q: Question: What year did Masashi win national amateur title at Senshu University? Passage 1:He is the brother and usurper of Numitor and son of Procas. He was said to have reigned 42 years before his death (794-752 BC). His brother had been king, but Amulius overthrew him, killed his son, and took the throne. He forced Rhea Silvia, Numitor's daughter, to become a Vestal Virgin, a priestess of Vesta, so that she would never bear any sons that might overthrow him. However, she was raped or seduced by the god Mars, resulting in the birth of the twins. Rhea was thrown into prison and her sons ordered to be thrown into the river Tiber. The twins washed up onto dry land and were found by a she-wolf who suckled them. Later their mother was saved by the river god Tiberinus who ended up marrying her. Romulus and Remus went on to found Rome and overthrow Amulius, reinstating their grandfather Numitor as king of Alba Longa.
 Passage 2:During construction of Unit 4, a cooling tower was commissioned by Cincinnati Gas and Electric (CG&E) (a forerunner of Duke Energy) in order to meet pollution control mandates set by the State of Ohio. Its four smokestacks were upgraded with electrostatic precipitators to prevent fly ash from being released into the atmosphere. Stuart was the test site for the Low- Cell Burner (LNCB) designed by Babcock & Wilcox. The LNCB project utilized Unit 4 over a duration of 53 months from 1990–1994. The test confirmed that a LNCB can reduce nitrogen oxide () emissions by more than 50%, but the carbon monoxide (CO) emissions were inconclusive. Each unit at Stuart were retrofitted with selective catalytic reduction (SCR) systems between 2003–2004 by Black & Veatch. The SCRs were installed to comply with the Clean Air Act's 1990 amendments and Ohio's State Implementation Plan (SIP). Flue-gas desulfurization (FGD) equipment, designed by Black & Veatch with assistance from the Chiyoda Corporation was installed at J.M. Stuart in 2008. The FGD equipment reduced 97% of the plant's sulfur dioxide () emissions. In order to support the FGD process, a smokestack was constructed.
 Passage 3:Oso was interested in sumo from a young age, as his father was the director of the Ibaraki Prefecture sumo association. He won national amateur titles at high school and at Senshu University, where he was a rival of Tosanoumi. He made his professional debut in January 1993 in the third makushita division, as due to his amateur achievements he had been given makushita tsukedashi status. He breezed through makushita undefeated with two consecutive 7–0 scores to earn promotion to the second jūryō division, whereupon he changed his shikona from Oso to Musōyama, meaning "twin warrior mountain." He made his debut in the top makuuchi division in September 1993. It took him only seven tournaments from his professional debut to make the san'yaku ranks, debuting at sekiwake in March 1994. In September he won his first eleven matches, finishing as runner up to Takanohana with a fine 13–2 record. Over the next few years he was regularly ranked at either sekiwake or komusubi, but was unable to make the next step up. He suffered a number of injuries, including a dislocated shoulder and a persistent problem with his left big toe which affected his speed of movement.
