Example Input: Question: Who founded the magazine that named Alan Webb the "High School athlete of the Year" in 2001? Passage:Webb attended South Lakes High School in Reston, Virginia. In 1999, he broke Jim Ryun's national sophomore mile record of 4:07.8 by running 4:06.94. During the fall season of his senior year, Webb placed second at the 2000 Foot Locker Cross Country Championships behind Dathan Ritzenhein. At the New Balance Games in January 2001, Webb's mile time of 3:59.86 at New York City's Armory made him the first American high schooler ever to run a sub-four minute mile indoors. Webb's time broke the previous American indoor high school record of Thom Hunt a 4:02.7 as well as Hunt's indoor HS AR in the 1500 m (3:46.6) as Webb came through the 1500 mark in 3:43.27. Webb's record was surpassed fifteen years later by Andrew Hunter from Loudoun Valley High School in Virginia with a time of 3:58.25 set on the same track. Four months later, at the age of 18 years, 4 months, and 14 days, on May 27, 2001 at the Prefontaine Classic, Webb ran a mile in 3:53.43 to shatter Ryun's 36-year-old national high school record of 3:55.3, which placed him first on the list of high school students who have run a four minute mile. En route Webb passed the 1500 mark in 3:38.26 to take down Ryun's 37-year-old high school AR of 3:39.0 set in 1964. He followed up his run at Prefontaine by winning the Virginia State High School 800 m title in 1:47.74 to become the fourth-fastest high schooler ever at that distance. He was Track and Field News "High School Athlete of the Year" in 2001.

Example Input: Question: The network does the Australian television series that features Stephanie Bendixsen and Steven O'donnell air on? Passage:Metroid: Other M received "generally favorable reviews", according to a review aggregator website Metacritic. GameSpot's Tom McShea praised the control scheme and combat system as "unique and responsive", and wrote that the search for secrets was "very rewarding". Craig Harris of IGN called the gameplay "a really impressive evolution of the old-school Metroid design", and GameTrailers described it as "a nice compromise between satisfying fans and opening up the series for a wider audience". In a review for an Australian television series Good Game, Stephanie Bendixsen enjoyed the game's atmosphere, while Steven O'Donnell remarked on how the developers "kept so simple, and yet it works so well." The writers from Famitsu also praised the game for the Sense Move technique and the switch between perspectives. The graphics were also well received. Christian Donlan of Eurogamer exclaimed that Other M bears graphical similarities to Metroid Prime which "tend to come across as nicely-built video game levels at best". Harris wrote that while the graphics are not being on par with the Prime series, it was still regarded as one of the best-looking games on the Wii. Tom Hoggins of The Daily Telegraph described the environments as "lush and detailed", and said they helped "capturing the ethos of old-school Metroid". Harris also praised the game's "storytelling with motion-captured acting and voice-over", and Wireds Chris Kohler applauded cutscenes "with slick graphic effects". The music was praised as atmospheric and faithful to the franchise, though McShea felt they were "more like outtakes from older entries than a moody new soundtrack".
