Example Input: Question: How many years had the Astor Hotel been in business the year that Ciampa scaled the exterior of it? Passage:A bricklayer by profession, Ciampa also worked in the entertainment business throughout the late 1940s and early 1950s, starring in Larry Sunbrock's Rodeo and Thrill Circus in New York City and then traveling with the circus to various U.S. and Canadian cities. Notably, his act did not include the typical, tightly choreographed feats of circus acrobatics such as trapeze swinging or trampolining, but rather improvised climbing and leaping stunts making use of scaffolding and circus rigging. Spectators were frequently alarmed by the apparently ad libbed and obviously dangerous nature of his performances. In 1947 Ciampa was arrested for having scaled the exterior of the Astor Hotel as a publicity stunt for the Sunbrock Circus, concerning onlookers who feared that he might have been attempting suicide.

Example Input: Question: How old was King Henry's eldest daughter when the search for a queen for James began? Passage:Forman and Bishop William Elphinstone of Aberdeen were the principal envoys who brokered a seven-year truce with King Henry VII of England at Aytoun in September 1497. They were assisted by the Spanish ambassador Pedro de Ayala, who recommended in May 1498 that diplomatic correspondence to Scotland should be copied to Forman, his influential friend. The search for a queen for James began in 1499 when negotiators were appointed to treat with King Henry for the marriage of his eldest daughter, Princess Margaret. Dispensation from the pope for the marriage was received as both James and Margaret were cousins, descended from John Beaufort, Marquess of Dorset. On 8 October 1501, Forman, now postulate to the see of Moray, was commissioned along with Robert Blackadder, Archbishop of Glasgow and Patrick Hepburn, 1st Earl of Bothwell to conclude the treaty of marriage. In that same year, King Henry, in gratitude for his services required that Thomas Savage, Archbishop of York institute Forman as Rector of the parish church of Cottingham. On 26 November 1501, Pope Alexander VI provided Forman to the bishopric of Moray and then only a few months later in 1502, Bishop Forman concluded the Treaty of Perpetual Peace with England at Richmond Palace. The formal proceedings that finally concluded the marriage terms of King James and Margaret Tudor were conducted in Glasgow Cathedral on 10 December 1502 where Forman was a signatory. He was then appointed as a commissioner to oversee the exchange of the ratified marriage treaties at the courts of Henry and James. James designated Forman to conduct Margaret to Scotland but while in England, gave King Henry an undertaking that the King of Scots would not renew the league with France unless Henry was first consulted. The procession to Scotland took them to Fast Castle near Berwick where they stayed with Forman's sister Isabel and her husband Alexander Oliphant of Kellie. In 1509, Forman became commendator of Dryburgh Abbey and tried unsuccessfully to obtain the commendatorship of the wealthy abbey of Kelso in 1511. The lands and possessions of the parson of Boleskin, south of Inverness were given to Forman (as bishop of Moray) in 1511 and then in 1512 he became the Keeper of the castle of Darnaway, near Forres, Chamberlain of Moray and Custumar north of the River Spey.

Example Input: Question: How many years were there between the completion of Westminster Abbey and the completion of the Cathedral of the Immaculate Conception? Passage:The construction of the cathedral was approved in 1894 by the Ministry of Internal Affairs under Tsarist Russia. Groundbreaking was in 1899; construction work began in 1901 and was completed ten years later. Three-aisled and built from red brick, the cathedral is based on a design by architect Tomasz Bohdanowicz-Dworzecki. The style was influenced by Westminster Abbey and Milan Cathedral. With the help of funds from Catholic parishes in Russia and its neighbouring states, the church was consecrated as a chapel for Moscow's Polish parish in 1911. In the aftermath of the Russian Revolution in 1917, the Provisional Government was overthrown by the Bolsheviks and Russia eventually became part of the Soviet Union in 1922. Because the promotion of state atheism was a part of Marxist–Leninist ideology, the government ordered many churches closed; the cathedral was closed in 1938. During World War II, it was threatened with demolition, and was used after the war for civil purposes, as a warehouse and then a hostel. Following the fall of communism in 1991, it returned to being a church in 1996. In 2002 it was elevated to the status of cathedral. Following an extensive and costly programme of reconstruction and refurbishment, the cathedral was reconsecrated in 2005.
