Example Input: Question: Which occured first, Ali's refusal to go to Vietnam or his being stripped of his championship? Passage:The fighters discuss their bouts against Muhammad Ali as well as their own lives and careers; Ali's fights against other opponents; his conversion to Islam and the assumption of the name Muhammad Ali; his relationship with the Nation of Islam organization (frequently referred to as the "black Muslims"), its leader, Elijah Muhammad (who bestowed Ali with his new name after he was briefly called Cassius X), and the Nation of Islam's most prominent minister, Malcolm X; Ali's refusal to be inducted into the United States Army to serve in the ongoing Vietnam War in 1967 on moral and religious grounds; the decision by the New York State Athletic Commission to strip him of his championship; his legal case and his reinstatement after the favorable June 28, 1970 decision by the Supreme Court of the United States. The Justices decided 8–0 (with Thurgood Marshall abstaining), that "... for the reasons stated, that the Department [of Justice] was simply wrong as a matter of law in advising that the petitioner's beliefs were not religiously based and were not sincerely held".

Example Input: Question: What is the population of the city where Wayne Russell is from? Passage:In July 2008, Kamloops MLA Claude Richmond announced he would not seek re-election in the May 2009 provincial election. Consequently, Lake announced that he would not stand for re-election as mayor but would instead seek to replace Richmond. With MLA Kevin Krueger moving to the new Kamloops-South Thompson riding, Lake was unopposed for BC Liberal nomination in the Kamloops-North Thompson. The election was expected to be close but Lake ultimately defeated the NDP candidate Doug Brown, student April Snowe for the Green Party, Clearwater resident Wayne Russell of the Refederation Party, and the Work Less Party's Keston Broughton. Lake's BC Liberals won the election and formed a majority government under Premier Gordon Campbell. In the first two sessions of the 39th Parliament Lake was appointed to the Select Standing Committee on Aboriginal Affairs and the Select Standing Committee on Health, however neither of those committees held any meetings. Premier Campbell did not include Lake in the cabinet but he was appointed as the Parliamentary Secretary for the Ranching Task Force under the Ministry of Agriculture and Lands. The Ranching Task Force began its work in July to review the province's role in the ranching industry, an industry which had been facing setbacks such as declining cattle prices and fewer exports following a Bovine spongiform encephalopathy outbreak and a strengthen currency value (relative to the US dollar). The task force's final report and recommendations were sent to the Minister of Agriculture and Lands in November 2009.

Example Input: Question: How many universities did Brooklyn have the year Wasson was born? Passage:Wasson was born Isabel Deming Bassett in Brooklyn, NY on January 11, 1897, daughter of urban planner Edward Bassett and Annie Preston Bassett, and sister of inventor and engineer Preston Bassett. Wasson graduated Phi Beta Kappa from Wellesley College in 1918, majoring in history so she could take a wide range of science courses. She took classes in geology after graduation at the University of Chicago and the Massachusetts Institute of Technology. She met her future husband, petroleum geologist Theron Wasson, whom she married in 1920, while working towards a master's degree in geology at Columbia University, which she finished in 1934. They had three children: Elizabeth W. Bergstrom, a biologist; Edward B. Wasson, a petroleum geologist; and Anne Harney Gallagher, an art historian. Wasson worked as a petroleum geologist in her husband's office at the Pure Oil Company from the early 1920s until 1928. She published two scholarly articles on geology, one co-authored with her husband about an oil field discovered by Pure Oil in 1914, and another by herself about the ages of rock formations in Ohio and new terminology for them; the latter was cited in a number of other papers and a recent book. After 1928 she spent over 50 years in River Forest, IL, teaching science in the local public schools, lecturing, bird watching (ornithology), and mentoring generations of young naturalists. She was quoted in this 1986 Chicago Tribune article as an expert on local geology at age 89. She was honored for her contributions to local history in 1982 when the Wasson Room was named after her in a local school to hold local history resources. Her interests included archaeology; she discovered a Native American religious mound in Thatcher Woods, near her house in River Forest, in the 1930s. An article about her discovery called her "the one who started the environmental education movement in America back in the 1920s and '30s." Theron and Isabel divorced in 1953 and she did not remarry. From 1953-1954, Wasson served as President of the Chicago Ornithological Society. Wasson also taught classes at the Morton Arboretum in Lisle, Illinois. She died in La Grange Park, IL, in 1994.
