Example Input: Question: The architectural style of which the church was built was a popular architectural style in the region for how many years? Passage 1:The church is constructed in punch-dressed sandstone ashlar, and has slate roofs with inserted skylight windows. Its architectural style is Early English. The plan consists of a four-bay nave without aisles, a two-bay chancel with a north chapel and a south vestry, and a west tower. The tower is in three stages, with clasping buttresses, and contains paired west doorways, a clock face in a diamond-shaped surround, and pairs of louvred bell openings. At the top of the tower is an embattled parapet with octagonal corner pinnacles, and there are more pinnacles at the angles of the nave. The bays of the nave are separated by buttresses, and each bay contains a corbel-table and a pair of lancet windows. The sides of the chancel also contain paired lancet windows, and the east window consists of a triple stepped lancet in a blank arch. The north chapel is gabled, and contains a wheel window. The interior has been remodelled, but originally it contained a three-sided gallery on cast iron columns.
 Passage 2:Robert Riabhach ("Grizzled") Duncanson, 4th Chief of Clann Dhònnchaidh, was a strong supporter of King James I (1406–1437) and was incensed by his murder at the Blackfriars Dominican Friary in Perth. He tracked down and captured two of the regicides, Sir Robert Graham and the King's uncle Walter Stewart, Earl of Atholl, as they hid above Invervack in Atholl, and turned them over to the Crown. They were tortured to death in the Grassmarket in Edinburgh on the orders of the Regent, James I's widow, Joan Beaufort (d. 1445). The Collins Scottish Clan & Family Encyclopedia states that they were put to death with considerable savagery. The Robertson crest badge of a right hand upholding an imperial crown was awarded by James II (1437–60) to the 4th chief on 15 August 1451 as a reward for capturing his father's assassins. The highly unusual third supporter (below the shield) on the Robertson coat of arms, of a "savage man in chains" is in reference to the capture of Graham. It is in honour of Robert Riabhach that his descendants took the name Robertson. James II also erected the clan lands into the Barony of Struan, which formerly took in extensive lands in Highland Perthshire, notably in Glen Errochty, the north and south banks of Loch Tay and the area surrounding Loch Rannoch. None of these lands are any longer in the possession of the clan.
 Passage 3:The rest of the matches for the show were announced on September 25, the day after Destruction in Kobe. Added were title matches for both of NJPW's junior heavyweight titles. In the IWGP Junior Heavyweight Championship match, Kushida would defend the title against Will Ospreay. After successfully defending the title against El Desperado on September 16 at Destruction in Hiroshima, Kushida was approached by Ospreay, who stated that he was being defined as the man who could not beat Kushida and wanting to change that perception, challenged him to a title match. This was followed by Hiromu Takahashi entering the ring, but before he could make his own challenge, he was knocked out by Ospreay. Ospreay had been defeated by Kushida in all four of their previous matches against each other, including the finals of the 2017 Best of the Super Juniors and What Culture Pro Wrestling's 2017 Pro Wrestling World Cup tournaments, as well as two IWGP Junior Heavyweight Championship matches, which took place on April 10, 2016, at Invasion Attack 2016 and June 19, 2016, at Dominion 6.19 in Osaka-jo Hall. In the IWGP Junior Heavyweight Tag Team Championship match, Funky Future (Ricochet and Ryusuke Taguchi) were set to defend the title against the mystery team known only as "Roppongi 3K". After dissolving his Roppongi Vice tag team with Beretta on September 16, Rocky Romero approached Ricochet and Taguchi after they had successfully defended the IWGP Junior Heavyweight Tag Team Championship against Taichi and Yoshinobu Kanemaru and announced he was bringing in a new team to challenge them for the title. Heading into the title match, the identities of Roppongi 3K were kept secret.

Example Input: Question: Which town was near the camp that, until May 1942, the Germans used it to mostly kill off Jews from Belgrade and other parts of Serbia? Passage 1:William Alfred Passavant was born in 1821 in Zelienople, Pennsylvania, the third and youngest son of Phillipe Louis Passavant and Fredericka Wilhelmina Basse (nicknamed "Zelie," hence the town's name). His grandfather, Baron Dettmar Basse, born in Iserlohn in the Ruhr Valley in what was then the Grand Duchy of Hesse and later became Germany, spent a decade in Paris as a diplomat and merchant before fleeing the Napoleonic Wars and emigrating to Philadelphia and then Pittsburgh in 1801. Drawn by the prospect of religious freedom and economic opportunity, the widower Baron bought 10,000 acres along Connoquenessing Creek in Butler County, Pennsylvania, began building a wood framed castle, and founded (with Christian Buhl) a new town complete with sawmill, brickyard, and an iron furnace. He also traveled and sent glowing letters back to Germany, persuading his daughter and her new husband (a French Huguenot who fled after repeal of the Edict of Nantes) to emigrate in 1807 from Frankfurt.
 Passage 2:The 1st King's Dragoon Guards was a cavalry regiment in the British Army. The regiment was raised by Sir John Lanier in 1685 as the 2nd Queen's Regiment of Horse, named in honour of Queen Mary, consort of King James II. It was renamed the 2nd King's Own Regiment of Horse in 1714 in honour of George I. The regiment attained the title 1st King's Dragoon Guards in 1751. The regiment served as horse cavalry until 1937 when it was mechanised with light tanks. The regiment became part of the Royal Armoured Corps in 1939. After service in the First World War and the Second World War, the regiment amalgamated with the 2nd Dragoon Guards (Queen's Bays) in 1959 to form the 1st The Queen's Dragoon Guards.
 Passage 3:After the April war of 1941 when Germany and its allies occupied and partitioned the Kingdom of Yugoslavia, entire Syrmia region (including the left bank of the Sava) became part of the Independent State of Croatia where they set the Ustaše regime. Nazi secret police, Gestapo, took over Sajmište. They encircled it with several rings of barbed wire turning it into what they referred to as "collection center" – a euphemism for a prison. It eventually became a concentration camp. Until May 1942 Germans used Sajmište concentration camp to mostly kill off Jews from Belgrade and other parts of Serbia. From April 1942 onwards, Serbian prisoners were transported in from Jasenovac and Stara Gradiška concentration camps run by ISC Croatian Ustaše. Partisans captured throughout Serbia were also sent to Sajmište. Detainees were also sent in from other parts of Yugoslavia, especially Serbs after major German offensives on briefly liberated territories. Executions of captured prisoners lasted as long as the camp existed. During their heavy “Easter bombing” of Belgrade, Allied aircraft bombed Sajmište on 17 April 1944, killing some 100 inmates and inflicting heavy damage on the camp itself, destroying all the buildings except for the Spasić pavilion and the Central tower..

Example Input: Question: Was the singer and actor who made "Footsteps" born prior to 1930? Passage 1:3DiTeams was developed in collaboration with Duke University Medical Center and used for medical education and team training. The game is intended for training and exercising of medical teams of practitioners of many levels of clinical expertise. The scope of practice of the tools in the game are geared toward care of a trauma patient and the interpersonal communications that surround the patient's care. The training is based on the United States Department of Defense Patient Safety Program and Agency for Healthcare Research and Quality's TeamSTEPPS curriculum. In 2006, the Telemedicine and Advanced Technology Research Center (TATRC), a division of the United States Army Medical Research and Materiel Command, funded a one-year $249,530 award to support the "3DiTeams: Gaming Environment for Training Healthcare Team Coordination Skills" study. The team was also awarded a 2-year $291,248 grant from the NIH Agency for Healthcare Research and Quality for their study on "Virtual Health Care Environments Versus Traditional Interactive Team Training."
 Passage 2:In February 2017 a diplomatic committee led by former driver Eliseo Salazar began discussions with Formula E CEO Alejandro Agag in Buenos Aires about the possibility of holding a race in the Chilean capital of Santiago. The ePrix was officially confirmed by the world governing body of motorsport, the Fédération Internationale de l'Automobile (FIA), in June, and was added to the 2017–18 Formula E calendar by the FIA World Motor Sport Council three months later. It was the fourth of twelve scheduled single seater electric car races of the season and took place on 3 February 2018. Prior to the event, a non-championship Formula One race won by Juan Manuel Fangio was held on the streets of Santiago in 1950. The press predicted the ePrix would be the largest sporting event in Chile since the 1962 FIFA World Cup, and organisers expected 20,000 people in attendance.
