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.
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-Lo 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 (18941973) 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.

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

Problem: Question: What is the differnce in mass of the two planets that Kepler claimed to have had an epiphany after demonstrating their periodic conjunction in the zodiac? Passage 1:Aquaman has guest starred in several episodes of the animated television series Justice League and Justice League Unlimited, where he was voiced by Scott Rummell. This version was based closely on the hot-headed antihero persona (the producers were aiming for "Conan underwater") of the 1994 and 2001 Aquaman comic book series, with the Viking-like appearance and hook prostheses. Here, he sacrificed his hand to save his infant son from being killed in a plot against his life by his evil brother Orm; Aquaman and his son were chained to a rock that was falling towards an underwater magma flow, and Aquaman only had time to free his right arm from his chains before cutting off his left hand to escape his remaining bonds. In the season two episode, "Hereafter", he is listed as a member of the Justice League on the Watchtower database after Superman was sent into the future. He later appeared in an homage episode alongside Superman, Batman, and Wonder Woman that pitted them against the Ultimen, modern pastiches of Samurai, Apache Chief, Black Vulcan, and the Wonder Twins from the Super Friends (Wind Dragon, Longshadow, Juice, Downpour, and Shifter, respectively). According to the website Television Without Pity, producers created Devil Ray and removed Aquaman and Black Manta from the series before the episode "To Another Shore" because the rights to Aquaman were no longer available due to an embargo on the characters because of the proposed and unaired Aquaman series.
Passage 2:Kepler's first major astronomical work, Mysterium Cosmographicum (The Cosmographic Mystery, 1596), was the first published defense of the Copernican system. Kepler claimed to have had an epiphany on July 19, 1595, while teaching in Graz, demonstrating the periodic conjunction of Saturn and Jupiter in the zodiac: he realized that regular polygons bound one inscribed and one circumscribed circle at definite ratios, which, he reasoned, might be the geometrical basis of the universe. After failing to find a unique arrangement of polygons that fit known astronomical observations (even with extra planets added to the system), Kepler began experimenting with 3-dimensional polyhedra. He found that each of the five Platonic solids could be inscribed and circumscribed by spherical orbs; nesting these solids, each encased in a sphere, within one another would produce six layers, corresponding to the six known planetsMercury, Venus, Earth, Mars, Jupiter, and Saturn. By ordering the solids selectivelyoctahedron, icosahedron, dodecahedron, tetrahedron, cubeKepler found that the spheres could be placed at intervals corresponding to the relative sizes of each planet's path, assuming the planets circle the Sun. Kepler also found a formula relating the size of each planet's orb to the length of its orbital period: from inner to outer planets, the ratio of increase in orbital period is twice the difference in orb radius. However, Kepler later rejected this formula, because it was not precise enough.
Passage 3:In 1993, the chairman of the Puerto Rico Electric Power Authority (AEE), Miguel Cordero, proposed a natural gas pipeline as part of the Government of Puerto Rico's plan to diversify Puerto Rico's energy sources. However, the proposal did not proceed during the administration of the Partido Nuevo Progresista (PNP) governor Pedro Rossello (19932000). In 2001, the Popular Democratic Party of Puerto Rico (PPD) won the gubernatorial elections, put Sila Calderon in La Fortaleza from 2001 to 2004, and appointed Hector Rosario as executive director of the AEE. The pipeline plan proposed by Cordero was shelved. In 2005, a natural gas pipeline project named Gasoducto del Sur (English: Southern Gas Pipeline) started construction under the PPD administration of Anibal Acevedo Vila. The Gasoducto del Sur pipeline would have transported natural gas from the EcoElectrica facilities in Penuelas to the power plant at Aguirre in Salinas. Acevedo Vila managed to complete about 25% of the Gasoducto del Sur project before being defeated by the opposing party, the PNP, in the 2008 elections. When the PNP took back La Fortaleza in 2009 via Luis Fortuno as governor, Miguel Cordero was reappointed executive director of the AEE, and the Gasoducto del Sur project, though a quarter of its way completed, was abruptly cancelled. The cancellation left the Government of Puerto Rico with a US$59million debt to the contractor, Skanska, and opened the way for the PNP's alternative project, Gasoducto del Norte. However, after strong environmental and popular opposition to the Gasoducto del Norte project, on 11 October 2012, the Puerto Rico Electric Power Authority (AEE) withdrew the entire Gasoducto del Norte Gsoducto del Norte permit application from the U.S. Army Corps of Engineers evaluation process, thereby stalling approval of the proposed pipeline indefinitely.
