[Q]: 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.

[Q]: Question: Who was president of Reed College the year John Backus graduated? Passage:John Backus was born and raised in Portland, Oregon, where he studied at Reed College, receiving a BA in 1932. He went on to graduate studies at the University of California, Berkeley, where he did research in nuclear physics at the Radiation Laboratory under Ernest Lawrence. He received an MA in 1936, and a PhD in 1940. In 1945 he was appointed Professor of Physics at the University of Southern California, a post he retained until his retirement in 1980. During the early part of his career, his research focussed on gaseous discharges in strong magnetic fields. He was also a musician, trained as a performer on piano, bassoon, clarinet and other woodwinds and received the degree of MMus in conducting from the University of Southern California in 1959. In his later career he turned increasingly to the study of musical acoustics, particularly those of wind instruments and organ pipes. In 1969 he published The Acoustical Foundations of Music, a book which became a standard text for introductory courses in musical acoustics. A second edition appeared in 1977. He received the Silver Medal of the Acoustical Society of America in 1986. Backus died in Los Angeles in 1988.
