You will be given a definition of a task first, then some input of the task.
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.

Question: Who won the season of X factor that Cowell was a judge with newcomer Rita Ora? Passage 1:Hart began his architectural career in Denver, finding work in 1898 as a draftsman for the firm of Willis A. Marean and Albert J. Norton, who later designed the Colorado Governor's Mansion (1908). In 1900, he joined Frank E. Edbrooke & Company, who had designed the Brown Palace Hotel (1892). By 1902, he had moved to California, where he spent a year drafting plans for new campus building of Stanford University, where conservative Richardsonian Romanesque detail adorned newly evolving California Mission Revival Style architecture under the guidance of Boston-based Shepley, Rutan & Coolidge. At Stanford, he was also exposed to the landscape architecture of Frederick Law Olmsted. He then spent a year working for the young firm of Meyer and O'Brien before joining the firm of Bliss and Faville just in time to work on their most famous project, the St. Francis Hotel, and other major buildings arising from the ashes of the San Francisco earthquake of 1906, including the Neoclassical architecture of the Bank of California and the more Beaux-Arts style of the Union Savings Bank (1909), the Columbia (now Geary) Theater (1909), and the Masonic Temple (1912).
 Passage 2:In the United States, geologic maps are usually superimposed over a topographic map (and at times over other base maps) with the addition of a color mask with letter symbols to represent the kind of geologic unit. The color mask denotes the exposure of the immediate bedrock, even if obscured by soil or other cover. Each area of color denotes a geologic unit or particular rock formation (as more information is gathered new geologic units may be defined). However, in areas where the bedrock is overlain by a significantly thick unconsolidated burden of till, terrace sediments, loess deposits, or other important feature, these are shown instead. Stratigraphic contour lines, fault lines, strike and dip symbols, are represented with various symbols as indicated by the map key. Whereas topographic maps are produced by the United States Geological Survey in conjunction with the states, geologic maps are usually produced by the individual states. There are almost no geologic map resources for some states, while a few states, such as Kentucky and Georgia, are extensively mapped geologically.
 Passage 3:In October 2013, it was reported that Cowell may return to the UK version of The X Factor for series 11 in the place of Gary Barlow, and on 7 February 2014, his return was officially confirmed. This resulted in the cancellation of the US version after three seasons by Fox. He joined judges Louis Walsh, Cheryl Fernandez-Versini, and new judge, former Spice Girls member Mel B, who replaced Nicole Scherzinger. For his eighth series, he was given the Over 25s category. On 13 December, Ben Haenow and Fleur East reached the final two, which meant that Cowell was the winning mentor for the first time since series 3 in 2006, when he had both Leona Lewis and Ray Quinn in the final. Haenow became the eleventh winner on 14 December. In March 2015, it was announced that Cowell would return to the X Factor for its twelfth series along with veteran judge Cheryl Fernandez-Versini, and newcomers Rita Ora and BBC Radio 1 DJ Nick Grimshaw.
