Example Input: Question: How long did the defending champion of the IWGP Junior Heavyweight Championship who defeated Richards in 2010 hold the title? Passage:In 2010 Richards was invited to take part in New Japan Pro Wrestling's Best of the Super Juniors tournament along with fellow North American and ROH wrestler, Kenny Omega. Richards entered the two-week-long tournament on May 30, but although he managed to win five out of his seven matches, he finished third in his block and narrowly missed advancing to the semifinals of the tournament. After the tournament Richards began working regularly for New Japan Pro Wrestling, joining the promotion's top heel stable Chaos, and no longer made appearances for Pro Wrestling Noah. In November 2010 Richards and Rocky Romero, reviving the No Remorse Corps name, made it to the finals of a five-day-long Super J Tag League tournament, before being defeated by their Chaos team mates Jado and Gedo. On December 11, 2010, Richards received a shot at the IWGP Junior Heavyweight Championship, but was defeated by the defending champion, Prince Devitt. On May 3, 2011, Richards and Romero unsuccessfully challenged Devitt and Ryusuke Taguchi, known collectively as Apollo 55, for the IWGP Junior Heavyweight Tag Team Championship. On May 26, Richards entered the 2011 Best of the Super Juniors tournament and after winning six out of his eight round robin stage matches, which included a win over the reigning IWGP Junior Heavyweight Champion Prince Devitt, Richards finished second in his block and advanced to the semifinals of the tournament. On June 10, Richards was eliminated from the tournament in the semifinals by the eventual winner of the entire tournament, Kota Ibushi. On October 10, 2011, at Destruction '11, Richards and Romero defeated Prince Devitt and Ryusuke Taguchi to win the IWGP Junior Heavyweight Tag Team Championship for the first time. Richards and Romero made their first successful title defense on November 12 at Power Struggle, defeating the team of Kushida and Tiger Mask. As a result of pinning Prince Devitt in the IWGP Junior Heavyweight Tag Team Championship match, Richards was granted another shot at his IWGP Junior Heavyweight Championship on December 4, but failed in his attempt to become a double champion. On January 4, 2012, at Wrestle Kingdom VI in Tokyo Dome, Richards and Romero lost the IWGP Junior Heavyweight Tag Team Championship back to Devitt and Taguchi. On February 12 at The New Beginning, the No Remorse Corps defeated Apollo 55 to regain the IWGP Junior Heavyweight Tag Team Championship. As a result, Richards received his third shot at the IWGP Junior Heavyweight Championship on March 10, but was yet again defeated by Prince Devitt. On May 2, Richards and Romero were stripped of the IWGP Junior Heavyweight Tag Team Championship, after a car accident forced Richards to miss his flight to Japan and the following day's Wrestling Dontaku 2012 event, where the two were scheduled to defend the title against Jushin Thunder Liger and Tiger Mask. Despite being able to wrestle in the United States, New Japan also pulled Richards from the 2012 Best of the Super Juniors tournament, citing doctor's orders.

Example Input: Question: How long had Christchurch been in existence for when Gould was born? Passage:Born in the Christchurch suburb of Fendalton on 19 October 1925, Gould came from a well-connected Canterbury family. His father was Derrick William Joseph Gould, a prominent businessman, racehorse owner and captain of the New Zealand polo team, and his mother was Elisabeth Mary Gould (nėe Elworthy). His paternal grandfather was George Gould, whose father, also called George Gould, was one of the founders in 1851 of the financial agents Gould Beaumont and Company that in 1919 amalgamated with two other firms to become Pyne Gould Guinness, one of New Zealand's largest stock and station agents. Other notable relatives on his father's side of the family include his father's cousin, the historian George Macdonald, and former British Labour MP Bryan Gould, who is a descendant of the elder George Gould. David's mother was a granddaughter of both Churchill Julius, the first Anglican Archbishop of New Zealand, and Edward Elworthy, an important landowner in South Canterbury. She was thus a first cousin of Charles Elworthy, Baron Elworthy, and niece of Sir George Julius and Awdry Julius.
