Example Input: Question: In which country did McNab play professional ice hockey after he recovered from his back surgery? Passage:After playing junior hockey in Saskatoon, Saskatchewan, McNab played on the Omaha Knights of the USHL in the 1946–48 season before being called up to the Detroit Red Wings of the National Hockey League in 1947. He would play on and off with the Red Wings until 1951, playing on the team that won the Stanley Cup in 1950. He played for the Indianapolis Capitols of the American Hockey League in 1950–51. Before the 1951–52 season, he was traded by the Red Wings to the Chicago Black Hawks, but never played for the team. Back surgery kept him out of action in 1951–52 and McNab then joined the New Westminster Royals of the Western Hockey League, where he played for seven seasons, retiring in 1959. He was voted league MVP in 1955, scoring 32 goals and 81 points.

Example Input: Question: When did the dynasty that Ji was born during start? Passage:Jiang Ji (died 18 May 249), courtesy name Zitong, was an official and military general of the state of Cao Wei during the Three Kingdoms period of China. Born in the late Eastern Han dynasty, Jiang Ji started his career as a low-level official in his native Yang Province before becoming a subordinate of Cao Cao, the warlord who controlled the central government towards the end of the Eastern Han dynasty. After the end of the Eastern Han dynasty, he served in the state of Cao Wei through the reigns of the first three emperors – Cao Pi, Cao Rui and Cao Fang – and held various appointments in the military before rising to Grand Commandant, one of the top positions in the central government. During his service in Wei, he was known for being candid in giving advice to the emperor on various issues, including consolidating power, halting labour-intensive construction projects, and officials' abuses of power. In February 249, he joined the regent Sima Yi in staging a successful coup d'état against his co-regent Cao Shuang, but died from illness a few months later.

Example Output: Born in the late Eastern Han dynasty, Jiang Ji started his career as a low-level official in his native Yang Province before becoming a subordinate of Cao Cao, the warlord who controlled the central government towards the end of the Eastern Han dynasty

Example Input: Question: Is Prague the capital of a country? Passage:In the months following up to the September 11 attacks, officials at the Czech Interior Ministry asserted that Atta made a trip to Prague on April 8, 2001, to meet with an Iraqi intelligence agent named Ahmed Khalil Ibrahim Samir al-Ani. This piece of information was passed on to the FBI as "unevaluated raw intelligence". Intelligence officials have concluded that such a meeting did not occur. A Pakistani businessman named Mohammed Atta had come to Prague from Saudi Arabia on May 31, 2000, with this second Atta possibly contributing to confusion. The Egyptian Mohamed Atta arrived at the Florenc bus terminal in Prague, from Germany, on June 2, 2000. He left Prague the next day, flying on Czech Airlines to Newark, New Jersey, U.S. In the Czech Republic, some intelligence officials say the source of the purported meeting was an Arab informant who approached the Czech intelligence service with his sighting of Atta only after Atta's photograph had appeared in newspapers all over the world. United States and Czech intelligence officials have since concluded that the person seen with Ani was mistakenly identified as Atta, and the consensus of investigators has concluded that Atta never attended a meeting in Prague.

Example Output:
