Problem:Question: What age was Tony Backhouse the year that he cowrote "Some Day"? Passage 1:Jenny Morris was born in Tokoroa, New Zealand and grew up in Hamilton with three brothers (Alistair, Rhys and Tam) and four sisters (Maxine, Bronte, Joanne and Shanley). Morris wrote a poem on the Vietnam War when she was 12 and used her sister's guitar to put it to music. Morris has stated that her influences include Aretha Franklin and Dusty Springfield. Her first professional performance was at age fifteen, at Andersons Theatre Restaurant, in Hamilton. In 1976 she became a singer with How's Your Father, who were finalists in the 'National Battle of the Bands'. She began working as a Home Economics teacher for two years at a high school near Wellington. Late in 1978 Morris joined an all-girl group, Wide Mouthed Frogs in Wellington, performing lead vocals. Fellow members were Kate Brockie on lead vocals, Andrea Gilkison on guitar, Tina Matthews on bass guitar, Bronwyn Murray on keyboards and Sally Zwartz on drums. In 1979 they released the track, "Some Day" for the compilation album, Home Grown Volume One; "Some Day" was cowritten with Tony Backhouse, guitarist of fellow Wellington band, The Spats, which also had a track, "Young Ladies in Hot Cars", on the compilation.
 Passage 2:In 1990, Sega president Hayao Nakayama sought a flagship series to compete with Nintendo's Mario franchise along with a character to serve as a company mascot. Several character designs were submitted as part of a contest. Among the designs was an egg-shaped man wearing pajamas who resembled Theodore Roosevelt, drawn by Naoto Ohshima. According to Ohshima, the resemblance to Roosevelt was unintentional, saying he was influenced by a variety of characters. Retrospective sources have indicated Ohshima based the character on Humpty Dumpty and Mario. The Roosevelt lookalike did not win the contest; rather, another Ohshima character, a hedgehog named Mr. Needlemouse—later renamed Sonic—prevailed. As development of the Sega Genesis game Sonic the Hedgehog progressed, however, programmer Yuji Naka and the rest of Sonic Team thought the rejected design was excellent and deserved inclusion in the game. Since the character could not be the protagonist, the team retooled him into the game's main antagonist.
 Passage 3:On 28 July 2012, Jin won the gold medal in the men's 10 m air pistol at the 2012 Summer Olympics. On 5 August, he won the gold medal in the 50m, becoming the first man to successfully defend the 50-metre pistol Olympic title. By doing so, Jin also became the first man to win the 10 metre air pistol and 50 metre pistol gold medals at the same Olympics, and one of the five shooters to win two individual gold medals at one Olympics, being the first man to have done so since Otto Olsen of Norway at the 1920 Summer Olympics. He is one of three shooters to have won three Olympic individual gold medals, along with Ralf Schumann of Germany and Kim Rhode of the United States. He became the first Korean athlete to win three individual Olympic gold medals, to win four (and five) individual Olympic medals, to defend an individual title in the Summer Olympics (while Sim Kwon-Ho won Olympic gold medals for Greco-Roman wrestling in 1996 and 2000, he won two different weight divisions), to win two individual gold medals at one Summer Olympic Games and to win an individual medal for one event at three consecutive Olympic Games (Kim Soo-Nyung won individual gold, silver and bronze medals respectively for archery in the 1988, 1992 and 2000 but these Olympics were non-consecutive).
