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.

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

Now, solve this instance: Question: Who was the perpetrator of the event that caused the capital to be in mourning? Passage 1:The combination of Guerrera's in ring skills, natural charisma and unique mask quickly landed him a regular job working for Empresa Mexicana de Lucha Libre (EMLL), Mexico's largest wrestling promotion. On September 25, 1981 Fuerza Guerrera made his first appearance at a major EMLL show as he wrestled and defeated Negro Casas on EMLL's 48th Anniversary show. On November 6, 1983 Guerrera defeated Aguila Venezolana in a tournament final to win the vacant Mexican National Lightweight Championship, the first professional wrestling championships of his career. In May, 1984 Guerrera vacated the title when he moved from the lightweight weight class (between and ) and into the Welterweight weight class (between and ). On December 3, 1985 Fuerza Guerrera captured the Mexican National Welterweight Championship when he defeated Javier Cruz. Guerrera held the title for approximately 240 days before vacating the title as he left EMLL to work for other wrestling promotions in Mexico. By late 1988 Guerrera had returned to EMLL and captured the NWA World Welterweight Championship on October 4, 1988 when he defeated Solar II and won the highest ranking title in the Welterweight division at the time. Guerrera would go on to make several successful title defenses until he lost to Águila Solitaria on June 2, 1980. Guerrera regained the title three days later and went on to have an 808-day reign that included successful title defenses against Pantera II, Americo Rocca, his trainer Gallo Tapado, Misterioso and Octagón. In 1989 Guerrera also began working part-time in the Tijuana, Baja California based World Wrestling Association promotion, winning the WWA Welterweight Championship twice in 1989 and 1990.
 Passage 2:On May 10, United States President Andrew Johnson had declared that the rebellion and armed resistance was virtually at an end, and had made plans with government authorities for a formal review to honor the troops. One of his side goals was to change the mood of the capital, which was still in mourning following the assassination of United States President Abraham Lincoln a month before at Ford's Theater. Three of the leading Federal armies were close enough to participate in the procession. The Army of the Tennessee arrived via train. The Army of Georgia, also under the command of William T. Sherman, had just completed its Carolinas Campaign and had accepted the surrender of the largest remaining Confederate army, that of Joseph E. Johnston. It arrived from North Carolina in mid-May and camped around the capital city in various locations, across the Potomac River from the Army of the Potomac, fresh off its victories over Robert E. Lee in Virginia. It had arrived in Washington on May 12. Officers in the three armies who had not seen each other for some time (in some cases since before the war) communed and renewed acquaintances, while at times, the common infantrymen engaged in verbal sparring (and sometimes fisticuffs) in the town's taverns and bars over which army was superior. Sherman, concerned that his Westerners would not present as polished an image as the eastern army, drilled his forces and insisted that uniforms be cleaned, buttons and brass shined, and that bayonets glistened.
 Passage 3:In the 1990s, Ingram's highest-profile team-up came again with Quincy Jones, on the song "The Secret Garden". This song also featured vocals by Barry White, El DeBarge, and Al B. Sure!. Soundtrack songs were popular for Ingram in the 1990s. From the movie Sarafina! came "One More Time", and from City Slickers came "Where Did My Heart Go?" In 1991, he and Melissa Manchester performed the song "The Brightest Star" in the animated Christmas film Precious Moments Timmy's Gift. In 1993, they performed the song again in the film's sequel Precious Moments Timmy's Special Delivery. Ingram's 1994 composition "The Day I Fall in Love", a duet with Dolly Parton, was the theme song for the movie Beethoven's 2nd and was nominated for an Academy Award for Best Original Song. Ingram and Parton performed the song live on the Oscar broadcast. In 1997, he and Carnie Wilson co-wrote the song "Our Time Has Come" and lent it to the animated film Cats Don't Dance.
