Question: How long was Bill Hewitt the director? Passage:The Billy Bishop Regional Airport in the nearby Municipality of Meaford was named after him. His modest gravesite can be visited in the city's Greenwood Cemetery by those willing to take the time to locate the stone. His boyhood home is now a museum dedicated to his life and to Canada's aviation history. The town was also the home of National Hockey League (NHL) Hall of Fame goaltender Harry Lumley and the artist Tom Thomson (buried in the nearby village of Leith). Surgeon Norman Bethune, an avowed communist and pioneer of public medicine who gained notoriety in his innovative medical work with the Chinese army during the Second Sino-Japanese War, is an alumnus of the Owen Sound Collegiate and Vocational Institute. Legendary hockey broadcaster Bill Hewitt was once sports director of the local AM radio station, CFOS. Thomas William Holmes, another Victoria Cross winner, was also from Owen Sound, and the city's armoury bears his name.

Question: How many years were there between the death of Charlemagne and the first award of the Charlemagne Prize? Passage:The Charlemagne Prize (; full name originally Internationaler Karlspreis der Stadt Aachen, International Charlemagne Prize of the City of Aachen, since 1988 Internationaler Karlspreis zu Aachen, International Charlemagne Prize of Aachen) is a prize awarded for work done in the service of European unification. It has been awarded annually since 1950 by the German city of Aachen. It commemorates Charlemagne, ruler of the Frankish Empire and founder of what became the Holy Roman Empire, who resided and is buried in Aachen. Traditionally the award is given to the recipient on Ascension Day in a ceremony in the town hall of Aachen. In April 2008, the organisers of the Charlemagne Prize and the European Parliament jointly created a new European Charlemagne Youth Prize, which recognises contributions by young people towards the process of European integration. Patrons of the foundation are King Philippe of Belgium, King Felipe VI of Spain, and Henri, the Grand Duke of Luxembourg.

Question: Which races did Compton finish in the top 5 during his rookie year? Passage:In 1997, Compton signed up with a new team, Impact Motorsports, to run the No. 86 Ford F-150 for the NASCAR Craftsman Truck Series Rookie of the Year Award. During his initial Truck Series season, Compton had three Top 5 finishes and a 13th-place finish in points, but fell well short of the top rookie award. For the 1998 season, in the third race of the season held at Phoenix International Raceway, Compton won his first career pole position, and finished in third in the race. The next week at Portland Speedway, he led all but two laps and won his first career Truck Series race. He got another win later that season at Heartland Park Topeka. He finished seventh in the final points standings and was named the Most Popular Driver. Compton had high hopes for 1999 season as Impact switched to Dodge Rams and getting a teammate in Randy Tolsma, but he failed to go to victory lane that season, although he did finish fourth in the points. Late that season, Compton began competing in some Winston Cup races for Melling Racing. Soon afterwards, Melling announced that Compton would driver theirNo. 9 Ford Taurus in the Winston Cup Series in 2000 season.
