Question: What was the founding date of the team Foster played against in the 2001 FA Trophy final? Passage:After a short period in Scotland, Foster returned to English football with Doncaster Rovers where his opportunities were limited, though he had a spell with Ilkeston Town on loan. In 2001, he signed for Forest Green Rovers in the Conference National. He made well over 100 appearances for the club and had a spell as captain. He also appeared for Forest Green in the 2001 FA Trophy final at Villa Park but was on the losing side in a 1-0 defeat to Canvey Island. He was highly regarded amongst the supporters at The Lawn and many were sad to see him leave when he departed for Halifax Town in 2004. He made just under 100 league appearances for Halifax at The Shay before a move in 2007 to Oxford United.

question:
Question: How long had Ferdinand I been in power the year Coimbra fell? Passage:The history of the county of Portugal is traditionally dated from the reconquest of Portus Cale (Porto) by Vímara Peres in 868. He was named a count and given control of the frontier region between the Limia and Douro rivers by Alfonso III of Asturias. South of the Douro, another border county would be formed decades later when what would become the County of Coimbra was conquered from the Moors by Hermenegildo Guterres. This moved the frontier away from the southern bounds of the county of Portugal, but it was still subject to repeated campaigns from the Caliphate of Córdoba. The recapture of Coimbra by Almanzor in 987 again placed the County of Portugal on the southern frontier of the Leonese state for most of the rest of the first county's existence. The regions to its south were only again conquered in the reign of Ferdinand I of León and Castile, with Lamego falling in 1057, Viseu in 1058 and finally Coimbra in 1064.

Question: How long had the party to which Fitch was awarded membership in 1951 been in operation at the time? Passage:In 1950, Fitch raced his Ford Flathead engined Fiat 1100, which he soon modified into the "Fitch Model B", and ended the year by driving a Jaguar XK120 in the Sebring Grand Prix of Endurance Six Hours. In 1951, in addition to campaigning in his Fitch-Whitmore, he boosted his early reputation by winning the Gran Premio de Eva Duarte Perón – Sport in his Allard-Cadillac J2. As a result of that win, Juan Perón generously awarded him membership in the Justicialist Party, whilst the trophy and a kiss were given by Eva Perón. He also clinched the support of Cunningham, whose financial clout allowed Fitch to race. He was drove a Cunningham C-2 for the Cunningham team at several races, including the 1951 24 Hours of Le Mans, scoring a number of impressive victories in the early ‘50s at then-fledgling road courses like Elkhart Lake and Watkins Glen, and was crowned the first SCCA National Sports Car Champion. In 1951, John raced an Effyh Formula Three car, winning at Bridgehampton and a class win at Giants Despair.
