Q: 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: How many children did the builder of the Longleat House have? Passage 1:After the Arrow Cross Party's coup and the resignation of Horthy on October 16, 1944 Ferenc Szálasi was appointed "Leader of the Nation". He established a Regent Council of three members, all from the Hungarian Nazi party. After the Soviet occupation of Hungary a High National Council formed in 1945 which was the collective head of state until the declaration of the Second Hungarian Republic. Members of the first High National Council were Béla Zsedényi (Speaker of the Interim National Assembly), Béla Miklós (Prime Minister) and Ernő Gerő (from the Hungarian Communist Party, later replaced by József Révai, then by Mátyás Rákosi). But the real power was in the hands of the Allied Control Commission, led by Kliment Voroshilov.
 Passage 2:Members of this band had already released an album in 1968 as The Rockets, and had appeared on record twice with Neil Young as Crazy Horse. The core trio from the Rockets, Danny Whitten, Billy Talbot, and Ralph Molina, provided instrumental backing for Young's 1969 album Everybody Knows This Is Nowhere, and performed on some songs from Young's 1970 album After the Gold Rush. Producer/keyboardist Jack Nitzsche, who had been a member of Phil Spector's Wrecking Crew and played on records by The Rolling Stones, had worked with Young on his debut album and on tracks for Buffalo Springfield. He was drafted into Crazy Horse to back up Young on their short tour in early 1970. During sessions for Gold Rush, they met teenage guitar prodigy Nils Lofgren, who joined the band in time for this album, picking up a contract with Reprise Records after the exposure garnered from their association with Young.
 Passage 3:The Thynne family descends from the soldier and courtier Sir John Thynne (died 1580), who constructed Longleat House between 1567 and 1579. In 1641 his great-grandson Henry Frederick Thynne was created a Baronet, of Caus Castle, in the Baronetage of England (some sources claim that the territorial designation is "Kempsford in the County of Gloucester"). He was succeeded by his son, the second Baronet. He represented Oxford University and Tamworth in the House of Commons and also served as Envoy to Sweden. In 1682 he was raised to the Peerage of England as Baron Thynne, of Warminster in the County of Wilts, and Viscount Weymouth, in the County of Dorset, with remainder to his younger brothers James Thynne (who died unmarried) and Henry Frederick Thynne and the heirs male of their bodies.
