Example Input: Question: Who was the eldest of Liu's oath brothers? Passage:Liu Bei and his oath brothers Guan Yu and Zhang Fei swore allegiance to the Han Empire in the Oath of the Peach Garden and pledged to do their best for the people. However, their ambitions were not realised as they did not receive due recognition for helping to suppress the Yellow Turban Rebellion and participating in the campaign against Dong Zhuo. After Liu Bei succeeded Tao Qian as the governor of Xu Province, he offered shelter to Lü Bu, who had just been defeated by Cao Cao. However, Lü Bu betrayed his host, seized control of the province and attacked Liu Bei. Liu Bei combined forces with Cao Cao and defeated Lü Bu at the Battle of Xiapi. Liu Bei then followed Cao Cao back to the imperial capital, Xu, where Emperor Xian honoured him as his "Imperial Uncle". When Cao Cao showed signs that he wanted to usurp the throne, Emperor Xian wrote a secret decree in blood to his father-in-law, Dong Cheng, and ordered him to get rid of Cao. Dong Cheng secretly contacted Liu Bei and others and they planned to assassinate Cao Cao. However, the plot was leaked out and Cao Cao had Dong Cheng and the others arrested and executed along with their families.

Example Input: Question: How old is the person Smith got into an altercation with as a teenager? Passage:Smith was born and raised in Brooklyn, New York. He became a wrestling fan in the late 1950s. A childhood friend claimed that they were the first wrestling fans to bring signs to local World Wide Wrestling Federation house shows. Around 1971, Smith also co-founded an unofficial fan club for Freddie Blassie with members wearing homemade "Blassie's Army" T-shirts. As a teenager, Smith had an altercation with Kevin Sullivan while attending a live event at Sunnyside Gardens. Sullivan had been hit with an unknown object at the end of his bout against Davey O'Hannon. Smith, who often cheered for the "heel" wrestlers, had been heckling Sullivan (then a "babyface") throughout the night causing the wrestler to believe that Smith was responsible. The young wrestling fan was brought to the dressing room by building security after the match where he was confronted by Sullivan, Gorilla Monsoon and Arnold Skaaland. Smith denied any wrongdoing and was allowed to leave. Smith continued watching wrestling after moving to Knoxville, Tennessee in the mid-1970s. He eventually met Norvell Austin at a Southeastern Championship Wrestling. Austin later introduced Smith to Rick Conner who agreed to train him.

Example Input: Question: In what province is the North American city located where the Gazelle stopped after joining the Vineta for a cruise? Passage:Gazelle then joined Vineta for a cruise in North American waters that included a stop in Halifax, Nova Scotia; the ships then entered the Saint Lawrence River, steaming as far inland as Montreal, Canada. Gazelle arrived back in the Caribbean on 27 October, stopping in Saint Thomas. By the end of the year, Gazelle lay off Santo Domingo, the capital of the Dominican Republic; she had sent a landing party ashore to protect the German consulate owing to unrest in the country. She then moved to Port-au-Prince to send a detachment ashore there as well. Gazelle moved to Veracruz, Mexico in January 1904, where her commander made an official visit to the President of Mexico, Porfirio Díaz. The ship visited Belize in British Honduras and several islands in the area. She next returned to Newport News for maintenance, where she was visited by Theodore Roosevelt, the President of the United States. On 19 June, she was recalled to Germany, arriving back in Kiel on 18 July. She was decommissioned in Danzig on 3 August and taken into the Kaiserliche Werft (Imperial Shipyard) there for an overhaul. During the overhaul, her troublesome Niclausse boilers were replaced with navy-built models.
