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: How old was Pleistarchus's brother when he sent Pleistarchus to make headway against Ptolemy? Passage:Pleistarchus or Plistarch (; lived 4th century BC) was son of Antipater and brother of Cassander, king of Macedonia. He is first mentioned in the year 313 BC, when he was left by his brother in the command of Chalcis, to make headway against Ptolemy, the general of Antigonus, when Cassander himself was recalled to the defence of Macedonia. Again, in 302 BC, when the general coalition was formed against Antigonus, Pleistarchus was sent forward by his brother, with an army 12,000 foot and 500 horse, to join Lysimachus in Asia. As the Hellespont and entrance of the Euxine was occupied by Demetrius, he endeavoured to transport his troops from Odessus direct to Heraclea, but lost by far the greater part on the passage, some having been captured by the enemy's ships, while others perished in a storm, in which Pleistarchus himself narrowly escaped shipwreck. Notwithstanding this misfortune, he seems to have rendered efficient service to the confederates, for which he was rewarded after the battle of Ipsus (301 BC) by obtaining the province of Cilicia, as an independent government. This, however, he did not long retain, being expelled from it in the following year by Demetrius, almost without opposition. Afterwards he is recorded in inscriptions as the ruler of Caria; he was apparently given this province after the battle of Ipsus, and ruled there for at least seven years. Pausanias mentions him as having been defeated by the Athenians in an action in which he commanded the cavalry and auxiliaries of Cassander; but the period at which this event took place is uncertain. It is perhaps to him that the medical writer, Diocles of Carystus, addressed his work, which is cited more than once by Athenaeus, as τα προς Πλεισταρχον Υγιεινα.

Example Input: Question: Who owned the Columbus Crew when the year they signed Armas to the team? Passage:In 1999, Armas signed for the Maryland Mania in the USL A-League. He began the 2000 season with the Raleigh Capital Express, playing four games. He also spent time with D.C. United. In June 2000, the Columbus Crew signed Armas as a Discovery Player. He played four regular season games with the Crew. He also played on 2000 Open Cup game for the Crew, coming on for John DeBrito in the 66th minute. He also went on loan to MLS Pro 40 for one game. The Crew waived him at the end of the season. In November 2000, the Tampa Bay Mutiny claimed Armas off waivers, but released him before the season. In 2001, John Dugan, who had coached the Express in 2000, became the new head coach of the Atlanta Silverbacks. He promptly signed Armas. On June 12, 2001, half way through the season, the Silverbacks traded Armas to the Minnesota Thunder in a three-way trade which sent Andrew Restrepo from the Rochester Rhinos to Atlanta and Stoian Mladenov to the Rhinos from Minnesota. In 2002, Armas played three games with the Cincinnati Riverhawks. In 2003, he played seventeen games for the Carolina Dynamo, scoring five goals and adding 16 assists as the Dynamo took the league title. Armas was selected as a first team All Star. He then moved to the Pittsburgh Riverhounds for the 2004 USL Second Division season and was back with Carolina for the 2005 season.
