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 plays Vera Juarez in The New World? Passage 1:Vera first appears in "The New World" when she is called upon to treat Rex Matheson (Mekhi Phifer), who has been impaled through the chest by a metal pole. Vera conveys news that Rex has survived to his colleague Esther (Alexa Havins) along with the news that no one has died in the past 24 hours, which she corroborates with accounts from other hospitals. In "Rendition" Vera realises that the hospitals cannot cope and suggests overriding the orthodox triage system so that in the wake of "Miracle Day" those with less severe illnesses are treated first. She later joins a series of medical panels; she engages the help of one to provide Rex with instructions to concoct emergency EDTA which when used as a chelating agent saves the life of a poisoned and now mortal Jack (John Barrowman). "Dead of Night" marks the beginning of a sexual relationship between Rex and Vera; he later enlists her to aid Torchwood's infiltration of a Phicorp conference. Unlike onlookers, she is disgusted by the battle for popularity between Oswald Danes and a rival spokesperson which occurs on the grounds of her hospital. In "The Categories of Life", when the Washington medical panels are abandoned in the wake of a new system of categorising life Vera allies herself with the Torchwood group, now based in Los Angeles. She goes undercover as an inspector of the San Pedro overflow camp against Rex's wishes. Appalled at the inhumane conditions and low management standards she tells camp manager Colin Maloney (Marc Vann) she wants him prosecuted. Maloney shoots Juarez twice and takes her to a 'module' within the camp. This is revealed to be a giant oven used to burn surplus but still alive people; Vera is incinerated whilst a horrified Rex watches on.
 Passage 2:No church at Tong is mentioned in Domesday Book. At that point Roger de Montgomery, Earl of Shrewsbury, held the manor both as tenant-in-chief and as manorial lord. The cartulary of Shrewsbury Abbey shows that Earl Roger granted it the advowson of the church at Tong and a pension of half a mark from its income, so the church must have been built between Domesday in 1087 and his death in 1094. After Robert of Bellême, 3rd Earl of Shrewsbury forfeited his family’s lands through revolt, Tong and nearby Donington were granted by Henry I to Richard de Belmeis I, his viceroy in Shropshire and the Welsh Marches, who also became Bishop of London, and who held the churches on both estates from Shrewsbury Abbey until his death in 1127. He ensured the two churches were restored to Shrewsbury Abbey on his death but his secular holdings went to his nephew Philip de Belmeis, one of the founders of Lilleshall Abbey.
 Passage 3:In Austria, Gmunden, Graz, Innsbruck, Linz and Vienna all have tramway systems. With 173.4 km of track, Vienna's network is one of the largest in the world. The cars have been constantly modernised over the years and many are now ultra low-floored. Many of the Austrian tramlines have been in constant operation since they were first opened. Vienna started with horse trams in 1865 and electrification followed in 1897. Graz had horse trams in 1878 and electric cars in 1898 while Linz goes back to 1880 with electrification in 1897. The Gmunden Tramway, only 2.3 km long, is currently one of the shortest in the world, and with gradients of up to 9.6%, it is also one of the steepest and has become a popular tourist attraction. Innsbruck, which traditionally used second-hand trams from other cities, replaced its whole fleet with 32 Bombardier low-floor cars in Summer 2009. The Pöstlingbergbahn, in Linz, an unusual "mountain tramway", has a gradient of 10.6%, which makes it one of the world's steepest gradients on a surviving adhesion-only railway. The tramway now reaches the city centre via the tracks of the urban tram system.
