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 Input: Question: Who starred in the film considered to be one of the earliest slasher films? Passage 1:Chillag emigrated to Australia after the war, having found no surviving family back in Hungary and being unable to remake the family business following the arrival of communism. Marrying a British-born expatriate in 1950, he worked for the Australian Atomic Energy Commission between 1957 and 1963, living in Sydney. He moved to Leeds, England in 1962, to work in Boston Spa until retirement, whereupon he became a European Information Officer for Leeds Metropolitan University. His daughter, diagnosed with Down syndrome, prompted him to work voluntarily with Mencap, and he continued to give lectures on his experiences at the Imperial War Museum. In 2004, he published his memoirs, The Odyssey of John Chillag, a Hungarian Jew Born in Vienna 2006: From Győr in Hungary to Australia and England Via Auschwitz and Buchenwald.
 Passage 2:His work has proved very influential. Bava directed what is now regarded as the earliest of the Italian giallo films, The Girl Who Knew Too Much (1963) and Blood and Black Lace (1964). His 1965 sci-fi/ horror film Planet of the Vampires was a thematic precursor to Alien (1979). Although comic books had served as the basis for countless serials and children's films in Hollywood, Bava's  (1968) brought an adult perspective to the genre with its' Pop art influence of Andy Warhol and Roy Lichenstein. Many elements of his 1966 film Kill, Baby... Kill!, regarded by Martin Scorsese as Bava's masterpiece, also appear in the Asian strain of terror film known as J-horror. 1971's A Bay of Blood is considered one of the earliest slasher films, and was explicitly imitated in Friday the 13th Part 2.
 Passage 3:A member of the Aspietes family, of noble Armenian origin, Constantine was probably a close relative of his contemporary Michael Aspietes, a distinguished general killed in 1176. Like his relative, Constantine too had earned distinction during Manuel I Komnenos' campaign against the Hungarians in 1167. The historian John Kinnamos records that he held the rank of sebastos. He is next recorded as being active in 1190/1, during the Byzantine efforts to suppress the Bulgarian–Vlach rebellion of the brothers Peter and Ivan Asen. The historian Niketas Choniates records that, in an effort to sustain the troops and bolster their morale, Aspietes decided to distribute to them their delayed annual salaries. This act, however, enraged Emperor Isaac II Angelos, who saw in it almost an attempt to bribe the army to support Aspietes in overthrowing him. The emperor had Aspietes arrested and blinded, after which nothing further is known of him. He possibly died in the early years of the 13th century.

Example Input: Question: Which war occured first, the Seven Years' war or the Napoleonic Wars? Passage 1:France–United Kingdom relations are the relations between the governments of the French Republic and the United Kingdom of Great Britain and Northern Ireland (UK). The historical ties between France and the UK, and the countries preceding them, are long and complex, including conquest, wars, and alliances at various points in history. The Roman era saw both areas, except northern England and Scotland, conquered by Rome, whose fortifications exist in both countries to this day, and whose writing system introduced a common alphabet to both areas; however, the language barrier remained. The Norman conquest of England in 1066 decisively shaped English history, as well as the English language. In the medieval period, the countries were often bitter enemies, with both nations' monarchs claiming control over France. Some of the noteworthy conflicts include the Hundred Years' War and the French Revolutionary Wars which were French victories, and the Seven Years' War, Second Hundred Years’ War and Napoleonic Wars, from which Britain emerged victorious.
 Passage 2:It wasn't until the early 1970s when Cook won a prize in an important singing competition in Chicago, that she drew the attentiont of the opera world. She made her international opera debut in 1971 singing Zerbinetta in Richard Strauss's Ariadne auf Naxos touring with the Glyndebourne Festival Opera. In 1972 she joined the roster at the Theater Bremen as one of their principal sopranos, where she remained until 1975 and continued to perform as a guest until 1980. She appeared there and in other German opera houses in roles such as Adina in Donizetti's L'elisir d'amore, Constanze in Mozart's Die Entführung aus dem Serail, Despina in his Così fan tutte, the title role in Donizetti's Lucia di Lammermoor, Olympia in Offenbach's Les contes d'Hoffmann, Philine in Mignon by Ambroise Thomas, the Queen in Die Verurteilung des Lukullus, the Queen of the Night in Mozart's Die Zauberflöte, and Zerbinetta.

Example Input: Question: What is Probyn's Horse? 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.
