Problem: Background: Steven David "Steve" Levitt (born May 29, 1967) is an American economist known for his work in the field of crime, in particular on the link between legalized abortion and crime rates. Winner of the 2003 John Bates Clark Medal, he is currently the William B. Ogden Distinguished Service Professor of Economics at the University of Chicago, director of the Becker Center on Chicago Price Theory at the University of Chicago Booth School of Business. He was co-editor of the Journal of Political Economy published by the University of Chicago Press until December 2007. With journalist Stephen J. Dubner, he co-authored the best-selling book Freakonomics (2005) and its sequels SuperFreakonomics (2009)
Context: On April 10, 2006, John Lott filed suit for defamation against Steven Levitt and HarperCollins Publishers over the book Freakonomics and against Levitt over a series of emails to retired economist John B. McCall. In the book Freakonomics, Levitt and coauthor Stephen J. Dubner claimed that the results of Lott's research in More Guns, Less Crime had not been replicated by other academics. In the emails to McCall, who had pointed to a number of papers in different academic publications that had replicated Lott's work, Levitt wrote that the work by authors supporting Lott in a special 2001 issue of the Journal of Law and Economics had not been peer reviewed, alleged that Lott had paid the University of Chicago Press to publish the papers, and that papers with results opposite of Lott's had been blocked from publication in that issue.  A federal judge found that Levitt's replication claim in Freakonomics was not defamation but found merit in Lott's complaint over the email claims.  Levitt settled the second defamation claim by admitting in a letter to John B. McCall that he himself was a peer reviewer in the 2001 issue of the Journal of Law and Economics, that Lott had not engaged in bribery (paying for extra costs of printing and postage for a conference issue is customary), and that he knew that "scholars with varying opinions" (including Levitt himself) had been invited to participate. The Chronicle of Higher Education characterized Levitt's letter as offering "a doozy of a concession."  The dismissal of the first half of Lott's suit was unanimously upheld by The United States Court of Appeals for the Seventh Circuit on February 11, 2009.
Question: what was Lott's work that led to the suit
Answer: the book Freakonomics

Problem: Background: Danzig was born Glenn Allen Anzalone, the third of four sons born to a Protestant family of Italian, German, and Scottish heritage in Lodi, New Jersey. His father was a television repairman and a United States Marine Corps veteran of World War II and the Korean War. His mother worked at a record store. Danzig and his family also spent some time living in Revere, Massachusetts.
Context: Danzig has said he wishes to avoid extensive and exhaustive touring in the future, preferring instead to focus on his various music, film and comic book projects: "I don't really want to tour. My reason for not doing it is because I'm bored of it. I like being onstage, but I don't like sitting around all day doing nothing. I could be home, working." Danzig has started work on a third Black Aria album, and a covers album is set for release by the end of 2013. Danzig hopes to record a dark blues album involving Jerry Cantrell and Hank III. He is currently working on new Danzig material with Tommy Victor and Johnny Kelly.  In 2014, Danzig filed a lawsuit against Misfits bassist Jerry Only claiming Only registered trademarks for everything Misfits-related in 2000 behind Danzig's back, misappropriating exclusive ownership over the trademarks for himself, including the band's iconic "Fiend Skull" logo, violating a 1994 contract the two had. Danzig claims that after registering the trademarks, Only secretly entered into deals with various merchandisers and cut him out of any potential profits in the process. On August 6, 2014, a U.S. district judge in California dismissed Danzig's lawsuit.  On October 21, 2015 during an interview with Loudwire, Danzig stated his current tour with Superjoint could be his last.  On May 12, 2016 Danzig, Only, and Frankenstein announced they would perform together as the Misfits for the first time in 33 years in two headlining shows at the September 2016 Riot Fest in Chicago and Denver. He later noted that he would be "open to possibly doing some more shows". Danzig returned to the 2017 Riotfest with his band, Danzig.  The newest Danzig album Black Laden Crown was released on May 26, 2017.
Question: Did he ever go on tour?

Problem: Background: De Benneville "Bert" Bell (February 25, 1895 - October 11, 1959) was the National Football League (NFL) commissioner from 1945 until his death in 1959. As commissioner, he introduced competitive parity into the NFL to improve the league's commercial viability and promote its popularity, and he helped make the NFL the most financially sound sports enterprise and preeminent sports attraction in the United States (US). He was posthumously inducted into the charter class of the Pro Football Hall of Fame. Bell played football at the University of Pennsylvania, where as quarterback, he led his team to an appearance in the 1917 Rose Bowl.
Context: Bell entered Penn in the fall of 1914 as an English major and joined Phi Kappa Sigma. In a rare occurrence for a sophomore, he became the starting quarterback for Penn's coach George H. Brooke. On the team, he also was as a defender, punter, and punt returner. After the team's 3-0 start, Bell temporarily shared possession of his quarterbacking duties until he subsequently reclaimed them later in the season, as Penn finished with a record of 3-5-2.  Prior to Penn's 1916 season, his mother died while he was en route to her bedside. Nevertheless, he started the first game for the Quakers under new coach Bob Folwell, but mixed results left him platooned for the rest of the season. Penn finished with a record of 7-2-1. However, the Quakers secured an invitation to the 1917 Rose Bowl against the Oregon Ducks. Although the best offensive gain for Penn during their 20-14 loss to Oregon was a 20-yard run by Bell, he was replaced late in the game at quarterback after throwing an interception.  In the 1917 season, Bell led Penn to a 9-2 record. Afterwards, he registered with a Mobile Hospital Unit of the US Army for World War I and was deployed to France in May 1918. As a result of his unit participating in hazardous duty, it received a congratulatory letter for bravery from General John J. Pershing, and Bell was promoted to first sergeant. After the war, Bell returned to the United States in March 1919. He returned to Penn as captain of the team in the fall and again performed erratically. The Quakers finished 1919 with a 6-2-1 record. Academically, his aversion to attending classes forced him to withdraw from Penn without a degree in early 1920. His collegiate days ended with his having been a borderline All-American, but this period of his life had proven that he "possessed the qualities of a leader."
Question: what happened in 1914?
Answer:
Bell entered Penn in the fall of 1914
