Example Input: Question: How long did the Teutonic Knights control the Chelmno Land? Passage 1:At the beginning of the 13th century, a Prussian trade route developed that crossed over an isthmus between two large lakes, the Sicieńskie lake and the Zamkowe ("Castle lake"). A defensive wall was built at this spot, and later, a settlement was constructed there as well. The place is mentioned in a twelfth-century document regarding a battle in which Henry of Sandomierz was killed. Under the name "Wambresia" the town was mentioned in a 1251 Prussian Document issued at Chełmża. Bishop Heidenreich of Bishopric of Chełmno received the Chełmno Land from the pope. The Polish duke Konrad I of Masovia turned possession of the settlement over to the bishop of Chełmno. This created a problem because the Teutonic Knights were in control of the Chełmno Land, and a dispute began between the Bishop of Chełmno and the Knights. The Pope at the time, Innocent IV, was not keen to continue the dispute and installed the Bishop as the rightful ruler of the settlement. This disagreement was the first historical mention of the settlement. In 1251, a large church, St. Simon and Judah, was built in the city.
 Passage 2:During those two years Warner also played two games against John Heisman, another future coaching legend. Heisman was the head coach at Auburn University, and they faced each other in the 1895 and 1896 games of the "Deep South's Oldest Rivalry," an annual confrontation which has continued to the present day. In 1895, the Auburn Tigers defeated the Bulldogs 12–6. The Auburn team was led by quarterback Reynolds "Tick" Tichenor, known for his punt returns. Tichenor had executed the first "hidden-ball trick" in an earlier Auburn game against Vanderbilt, and used it again against Georgia. The next year, Tichenor faced Georgia's Richard Von Albade Gammon, a star quarterback in his first year under Warner. Both quarterbacks played well and, unlike the previous year, Warner's team won 16–6. The second touchdown came right after the first onside kick in the South.
 Passage 3:Stanford Talisman is a student a cappella group at Stanford University, dedicated to sharing stories through music. Started in 1990 by Stanford student Joseph Pigato, their roots are in music from South Africa and the African diaspora, but they have since broadened their horizons to include music from all over the world. They perform not only locally in the greater San Francisco Bay Area but also around the world. Their most recent tour was to Hawai'i in the spring of 2018. The group has also traveled to South Africa (2016) and the American Southwest (2017). The group won the 1997 ICCA competition and notable performances include the 1996 Olympic Games, the White House, with 10-time Grammy award winner Bobby McFerrin in 2005 and 2019, with Seal in 2009, with Joan Baez in 2019, annually at Stanford Graduation Baccalaureate, and their sold-out 25th Anniversary Show in Bing Concert Hall in 2015.

Example Input: Question: Did the man who founded the strong LDP faction and the man whose hands it later fell into both serve as Prime Minister of Japan? Passage 1:In 1922, Heitler began his study of physics at the Karlsruhe Technische Hochschule, in 1923 at the Humboldt University of Berlin, and in 1924 at the Ludwig Maximilian University of Munich (LMU), where he studied under both Arnold Sommerfeld and Karl Herzfeld. The latter was his thesis advisor when he obtained his doctorate in 1926; Herzfeld taught courses in theoretical physics and one in physical chemistry, and in Sommerfeld's absence often took over his classes. From 1926 to 1927, he was a Rockefeller Foundation Fellow for postgraduate research with Niels Bohr at the Institute for Theoretical Physics at the University of Copenhagen and with Erwin Schrödinger at the University of Zurich. He then became an assistant to Max Born at the Institute for Theoretical Physics at the University of Göttingen. Heitler completed his Habilitation, under Born, in 1929, and then remained as a Privatdozent until 1933. In that year, he was let go by the university because he was Jewish.
 Passage 2:Hashimoto became a key figure in the strong LDP faction founded by Kakuei Tanaka in the 1970s, which later fell into the hands of Noboru Takeshita, who then was tainted by the Recruit scandal of 1988. In 1991, the press had discovered that one of Hashimoto's secretaries had been involved in an illegal financial dealing. Hashimoto retired as Minister of Finance from the Second Kaifu Cabinet. Following the collapse of the bubble economy, the LDP momentarily lost power in 1993/94 during the Hosokawa and Hata anti-LDP coalition cabinets negotiated by LDP defector Ichirō Ozawa. Hashimoto was brought back to the cabinet when the LDP under Yōhei Kōno returned to power in 1994 by entering a ruling coalition with traditional archrival Japanese Socialist Party (JSP), giving the prime ministership to the junior partner, and the minor New Party Harbinger (NPH). Hashimoto became Minister of International Trade and Industry in the Murayama Cabinet of Tomiichi Murayama. As the chief of MITI, Hashimoto made himself known at meetings of APEC and at summit conferences.

 Passage 2: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.
