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.

Question: Did the highest scoring fighter ace have any siblings? Passage:After a short rest, the 90th continued across the Moselle River to take Mainz, 22 March, and crossed the rivers Rhine, the Main, and the Werra in rapid succession. Pursuit continued to the Czech border, 18 April 1945, and into the Sudetes mountain range. The division was en route to Prague when they came upon the remaining 1500 emaciated prisoners left behind by the SS at Flossenbürg concentration camp. Today, a memorial wall at the former camp honors the 90th as the liberators of Flossenbürg concentration camp. A week later, word came that the war in Europe ended on 8 May 1945. On that same day, Erich Hartmann, the highest-scoring fighter ace in history, along with a squadron of the elite Jagdgeschwader 52 fighter wing (the highest-scoring fighter wing in history), surrendered to the 90th.

Question: What are the name of the band members that Cornell McFadden played with in The Insect Trust before he joined Archie Turner's band? Passage:After graduating from high school in 1964, Archie studied at Memphis State College while continuing to play with the Impalas, and occasionally made recordings as a session musician. He dropped out of college, and in 1968 was drafted into the US Army, initially forming a band at Fort Polk, Louisiana with his cousin, Donny Mitchell. He was transported to Vietnam as a member of an infantry unit, eventually forming a band there. He was recognized in Stars and Stripes magazine as 1969 Entertainer of the Year in Vietnam. Returning to Memphis in 1970, he restarted his degree but changed his major to Psychology. He also formed a new rock band, Blackrock, with Cornell McFadden (drums – previously a member of The Insect Trust), Kirk Dudley (bass), and Willie Pettis (guitar). They recorded one single, "Blackrock, Yeah, Yeah", for the local Select-O-Hits label, and – with Pettis replaced by Larry Lee – traveled to California where they auditioned for Bill Graham, though nothing came of the session and the band split up in 1971. "Blackrock, Yeah, Yeah", co-written by Turner, was sampled on the 2014 album ...And Then You Shoot Your Cousin by The Roots.
