Question: Question: What city did Stevens complete a Ph.D. in? Passage:In 1980, Stevens joined the Army under their split option training program and conducted basic training at Fort Dix, New Jersey and advanced individual training at Fort Sam Houston, Texas. While engaged in his military service, Stevens entered the University of Southern Maine in the Computer Science program in 1981. However, an enthusiastic professor (John Ricci) converted him to the study of Chemistry. He spent two summers working as an intern at the Brookhaven National Laboratory in Long Island with Professor Ricci, and Drs. Thomas Koetzle and Dick McMullan, where he first learned how to determine the molecular structure of compounds by X-ray and neutron diffraction. While there he also met a University of Southern California research team led by Dr. Robert Bau; after he obtained a Bachelor of Science degree in Chemistry at USM, he entered the University of Southern California in pursuit of a Doctor of Philosophy degree in Chemistry working with Professor Robert Bau and Nobel Laureate Professor, George Olah. He completed his Ph.D. in 26 months, graduating in 1988.

Question: Question: Who is the current owner of the team founded by Art Rooney? Passage:The Arizona Cardinals National Football League (NFL) franchise is allegedly suffering a curse by the citizens of Pottsville, Pennsylvania for undeservedly claiming the 1925 NFL championship from the Pottsville Maroons who were stripped of their title by the NFL in one of the greatest controversies in sports history. The curse will supposedly only be lifted when the championship is returned to Pottsville and to the correct shade of red team; this can only be met by overturning the original ruling, as Pottsville no longer has an NFL team and is too small to ever receive another one (with a metropolitan area roughly half the population of Green Bay, the league's smallest), making it impossible for the long-defunct Maroons to win another title. The Cardinals team holds the record for the longest championship drought, with their most recent championship coming in 1947, which is also the longest drought in American professional sports; the 1947 team was notable for having two of its members die during their playing careers within a year of each other, with Jeff Burkett dying in a plane crash following appendix surgery during the season and Stan Mauldin dying of a heart attack after a game the following season. Arizona also lost Super Bowl XLIII to another Pennsylvania team: the Pittsburgh Steelers (whose founder Art Rooney supported Pottsville's claim to the title). The franchise also leads the NFL in the total number of losses (730 through the 2017 season).

Question: Question: Which of the candidates that Barron supported in the 2012 primaries ended up on the presidential ballot? Passage:Before the 2012 Republican primary, Barron helped organize the "Draft Cheney 2012" movement, which was to convince the former vice president Cheney to seek the Republican presidential nomination in 2012. Early in the 2012 Republican primary process, Barron endorsed Herman Cain for the 2012 U.S. presidential election. After Cain dropped out, Barron endorsed Republican and later Libertarian Party presidential candidate Gary Johnson for the 2012 U.S. presidential election. He was a delegate to the 2012 Libertarian National Convention. In the 2012 Republican primary in the District of Columbia, Barron voted for Ron Paul. In October 2012, however, he announced he had decided to support and vote for Mitt Romney for President, even while continuing to serve as a D.C. elector for Johnson.
