Example Input: Question: Which national team that pull out of the Pacific Nations Cup has a longer history? Passage:The 2009 Pacific Nations Cup is a rugby union tournament held between five national sides on the Pacific Rim: Fiji, Japan, Samoa, Tonga and the Junior All Blacks. The New Zealand Māori team that won the tournament last year will no longer take part in this competition because of a decision taken by the New Zealand Rugby Union. Australia A has also decided to pull out due to a similar decision. The inaugural competition was held in 2006. This year the tournament will begin on June 12 and ends on July 3, 2009 and most of the matches will be hosted by Fiji. The awarding of the key international tournament to the Fiji Rugby Union represents a further boost to the continued development of rugby in the region. The two opening round matches will be played outside of Fiji with Samoa hosting the Junior All Blacks in Apia and Tonga entertaining the Fijians in Nukuʻalofa the following day before the tournament moves to Fiji for a 17-day festival of international rugby spread across three match venues: the ANZ National Stadium (Suva), Churchill Park (Lautoka) and Lawaqa Park (Sigatoka).

Example Input: Question: Which of the two teams Thomas was driving to Kansas City International Airport to see during has won the most Superbowls? Passage:On January 23, 2000, Thomas's 1999 Chevrolet Suburban went off Interstate 435 as he and two passengers were driving to Kansas City International Airport during a snowstorm for a flight to St. Louis to watch the between the St. Louis Rams and the Tampa Bay Buccaneers. Police reports indicated that Thomas, who was driving, was speeding at approximately 70 m.p.h. even though snow and ice were rapidly accumulating on the roadway. Thomas continued weaving erratically through traffic despite the weather. Thomas and one of the passengers were not wearing seat belts and both were thrown from the car; the passenger was killed instantly. The second passenger, who was wearing his safety belt, walked away from the scene uninjured. Thomas was left paralyzed from the chest down. By early February, Thomas was being treated at Miami's Jackson Memorial Hospital. The morning of February 8, 2000, while being transferred from his hospital bed to a wheelchair on his way to therapy, Thomas told his mother he was not feeling well. His eyes then rolled back, recalled Frank Eismont, an orthopedic surgeon at Jackson Memorial Hospital. Eismont said Thomas went into cardiorespiratory arrest and died as a result of a pulmonary embolism, a massive blood clot that developed in his legs and traveled to his lungs. Months later, Thomas' family sued General Motors for $73 million in damages stemming from the accident that Thomas caused. In 2004, a jury ruled that the family was not entitled to any money.
