PROBLEM: 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).

PROBLEM: Passage: Howard was born to Ossian Gregory Howard, a lawyer, and Lucy Denham Thurber on 11 June 1857. His relatives from his mother's side included the Harvard astronomer E.C. Pickering while other distant relatives included Senator J.M. Howard and President William Howard Taft. Shortly after his birth, the family moved from Rockford, to Ithaca, New York where his father worked with a law firm. Howard attended Ithaca Academy. An interest in insect collecting encouraged by his parents with the gift of The Butterfly Hunters by Mary Treat at the age of 10 followed by more books and at the age of 13, along with another collector friend, recorded the introduction of the European cabbage butterfly (Pieris rapae) in the Catskill region. Along with his friends, he founded the Ithaca Natural History Society to meet and discuss papers and insects. While out collecting one day, he met John Henry Comstock, who invited him to his lab at Cornell University. Howard enrolled in Cornell in September 1873, three years after the death of his father, and following the advice of his mother's friends, went to study civil engineering. Doing poorly in differential calculus made him drop engineering and he began to study other subjects including French, German, and Italian. He then joined Comstock's lab as the first research student and graduated in June 1877 with a thesis on respiration in the larva of Corydalis cornutus. He worked with Burt Green Wilder and Simon Henry Gage and received a masters at Cornell. In the 1880s, he also attended Columbian College (now George Washington University) for medicine, although he didn't complete it. He however received an honorary MD from the same university in 1911 for his contribution to medical entomology.
