Problem: Background: Born in Selma, Alabama, Mia was the fourth of six children of Bill and Stephanie Hamm. She wore corrective shoes as a toddler after being born with a club foot. Hamm spent her childhood on various United States Air Force bases around the world with her family. While living in Florence, Italy, Hamm first played soccer, which was hugely popular there; her entire family quickly became involved in the sport.
Context: On May 22, 1999, Hamm broke the all-time international goal record with her 108th goal in a game against Brazil in Orlando, Florida. The following month, she led the national team at the 1999 FIFA Women's World Cup, hosted by the United States. During the team's first group stage match against Denmark, she scored her 110th international goal and served an assist to Julie Foudy as the U.S. won 3-0. Against Nigeria, Hamm's low free kick was knocked into the goal by a Nigerian midfielder. Within a minute, Hamm scored with a free kick. She later served an assist to Kristine Lilly before being substituted in the 57th minute. The U.S. won 7-1 and secured a berth in the quarter-finals. During the team's final group stage match, head coach Tony DiCicco rested a number of players, including Hamm, who was substituted at half-time. The U.S. defeated Korea 3-0 and finished Group A with nine points. In the quarter-finals, the U.S. defeated Germany 3-2. Playing Brazil in the semi-finals, Hamm was knocked down in the penalty area late in the second half; Michelle Akers converted the subsequent penalty and their team won 2-0. After 90 minutes of scoreless regulation time and 30 minutes of sudden death, the 1999 FIFA Women's World Cup Final was decided by a penalty shootout between the U.S. and China. The five American players to take penalty kicks, including Hamm, converted; China missed one attempt so that the home team won. The final surpassed the 1996 Atlanta Olympic final as the most-attended women's sports event, with more than 90,000 people filling the Rose Bowl in Pasadena, California. It held the record until 2014 for the largest U.S. television audience for a soccer match with 17,975,000 viewers. As of July 2015, it ranks third following the 2015 FIFA Women's World Cup (25,400,000 viewers) and 2014 FIFA World Cup group stage match between the U.S. men's team and Portugal (18,220,000 viewers). Immediately following the final, Hamm collapsed in the locker room from severe hydration. She was treated by medical staff with an intravenous drip and three liters of fluids. After 12 hours of sleep, she joined the team for magazine cover shoots, went to Disneyland for a celebration rally, and made numerous television appearances. A week later, the team met President Clinton at the White House and flew with Hillary and Chelsea Clinton on Air Force One to Cape Canaveral. Her leadership and performance at the 1999 World Cup cemented Hamm as a soccer icon.

Problem: Background: Vladimir Vladimirovich Nabokov (; Russian: Vladimir Vladimirovich Nabokov, pronounced [vla'djimjIr na'bok@f] ( listen), also known by the pen name Vladimir Sirin; 22 April [O.S. 10 April] 1899 - 2 July 1977) was a Russian-American novelist, translator and entomologist.
Context: Nabokov's interest in entomology had been inspired by books of Maria Sibylla Merian he had found in the attic of his family's country home in Vyra. Throughout an extensive career of collecting he never learned to drive a car, and he depended on his wife Vera to take him to collecting sites. During the 1940s, as a research fellow in zoology, he was responsible for organizing the butterfly collection of the Museum of Comparative Zoology at Harvard University. His writings in this area were highly technical. This, combined with his specialty in the relatively unspectacular tribe Polyommatini of the family Lycaenidae, has left this facet of his life little explored by most admirers of his literary works. He described the Karner blue. The genus Nabokovia was named after him in honor of this work, as were a number of butterfly and moth species (e.g. many species in the genera Madeleinea and Pseudolucia bear epithets alluding to Nabokov or names from his novels). In 1967, Nabokov commented: "The pleasures and rewards of literary inspiration are nothing beside the rapture of discovering a new organ under the microscope or an undescribed species on a mountainside in Iran or Peru. It is not improbable that had there been no revolution in Russia, I would have devoted myself entirely to lepidopterology and never written any novels at all." The palaeontologist and essayist Stephen Jay Gould discussed Nabokov's lepidoptery in his essay, "No Science Without Fancy, No Art Without Facts: The Lepidoptery of Vladimir Nabokov" (reprinted in I Have Landed). Gould notes that Nabokov was occasionally a scientific "stick-in-the-mud". For example, Nabokov never accepted that genetics or the counting of chromosomes could be a valid way to distinguish species of insects, and relied on the traditional (for lepidopterists) microscopic comparison of their genitalia. The Harvard Museum of Natural History, which now contains the Museum of Comparative Zoology, still possesses Nabokov's "genitalia cabinet", where the author stored his collection of male blue butterfly genitalia. "Nabokov was a serious taxonomist," says museum staff writer Nancy Pick, author of The Rarest of the Rare: Stories Behind the Treasures at the Harvard Museum of Natural History. "He actually did quite a good job at distinguishing species that you would not think were different--by looking at their genitalia under a microscope six hours a day, seven days a week, until his eyesight was permanently impaired." The rest of his collection, about 4,300 specimens, was given to the Lausanne's Museum of Zoology in Switzerland. Though his work was not taken seriously by professional lepidopterists during his life, new genetic research supports Nabokov's hypothesis that a group of butterfly species, called the Polyommatus blues, came to the New World over the Bering Strait in five waves, eventually reaching Chile. Many of Nabokov's fans have tried to ascribe literary value to his scientific papers, Gould notes. Conversely, others have claimed that his scientific work enriched his literary output. Gould advocates a third view, holding that the other two positions are examples of the post hoc ergo propter hoc fallacy. Rather than assuming that either side of Nabokov's work caused or stimulated the other, Gould proposes that both stemmed from Nabokov's love of detail, contemplation, and symmetry.
Question: Why was he interested in entomology?
Answer:
Nabokov's interest in entomology had been inspired by books of Maria Sibylla Merian he had found in the attic of his family's country home in Vyra.
