Instructions: 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.
Input: 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 planets—Mercury, Venus, Earth, Mars, Jupiter, and Saturn. By ordering the solids selectively—octahedron, icosahedron, dodecahedron, tetrahedron, cube—Kepler 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 Rosselló (1993–2000). 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 Héctor 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 Aníbal Acevedo Vilá. The Gasoducto del Sur pipeline would have transported natural gas from the EcoEléctrica facilities in Peñuelas to the power plant at Aguirre in Salinas. Acevedo Vilá 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 Fortuño 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$59 million 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.
