Example Input: Question: Which of the two politicians that announced the Senate and Assembly committee investigating the Fort Lee lane closure scandal would merge into the bi-partisan joint New Jersey Legislative Select Committee on Investigation had the longest carreer? Passage:On January 21, 2014, Assemblyman John S. Wisniewski and State Senate majority leader Loretta Weinberg, whose district includes Fort Lee, announced that the Senate and Assembly committee investigating the matter would merge into the bi-partisan joint New Jersey Legislative Select Committee on Investigation, which they would co-chair and would have 12 members. While the committee initially focused on the Bridgegate scandal, it had the power to investigate other allegations against the Christie administration. On January 24, 2014 the members of the bi-partisan committee were announced; eight Assembly representatives, including five Democrats and three Republicans, and four Senators, including three Democrats and one Republican. At the time, 40% of the members of the New Jersey Legislature were Republican. Besides the two Democratic co-chairs, members included Assemblywoman Marlene Caride (D-Bergen), Assemblyman Michael Patrick Carroll (R-Morris), Senator Nia Gill (D-Essex), Senator Linda Greenstein (D-Middlesex), Assembly Majority Leader Louis Greenwald (D-Camden), Assemblywoman Amy Handlin (R-Monmouth), Assemblywoman Valerie Huttle (D-Bergen), Assemblywoman Holly Schepisi (R-Bergen), Assemblywoman Bonnie Watson Coleman (D-Mercer), and an unnamed Republican Senator. On January 27, both houses voted unanimously to combine the investigations, maintaining the partisan balance, and announced Kevin O'Toole's (R-Essex) inclusion despite his mention in a December 5 email from Wildstein to Michael Drewniak. Assemblyman Paul Moriarty (D-4th Legislative) District subsequently replaced Watson.

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: What position did Eziquiel Carrerra play for the Blue Jays? Passage:The Blue Jays opened the scoring in the third inning with five runs. Ezequiel Carrera walked with one out, moved to second on a wild pitch, then scored on Josh Donaldson's double. Back-to-back singles by Edwin Encarnacion and Jose Bautista made it 2–0. After Russell Martin walked to load the bases, Troy Tulowitzki cleared them with a triple. Rangers' starter Cole Hamels threw 42 pitches that inning, the most pitches in an inning he had ever thrown. Next inning, Melvin Upton Jr.'s leadoff home run made it 6–0. Rangers' shortstop Elvis Andrus's throwing error to first allowed Devon Travis to reach. He moved to second on a passed ball, then scored on Josh Donaldson's single to make it 7–0 and knock Hamels out of the game. The Rangers bullpen tossed 4 scoreless innings, but after back-to-back singles to lead off the ninth off Jake Diekman, Bautista hit a three-run home run amid boos from the Rangers crowd, giving the Blue Jays a 10–0 lead. Blue Jays' starter Marco Estrada went a strong 8 innings having given up only four hits and one earned run (in the ninth when Andrus hit a leadoff triple and scored on Shin-Soo Choo's groundout) on 98 pitches.
