Question: How many years apart are Telfer's parents? Passage 1:The son of Margaret Mellis and Adrian Stokes, he was born in St Ives and studied at the Slade School of Fine Art. He pursued postgraduate studies at the Brooklyn Museum Art School after being awarded a Beckmann Fellowship. He taught at Reading Art School and the Bath Academy in Corsham and exhibited his paintings in London, including a show at the Serpentine Gallery. In 1971, Stokes founded publishing firm Weproductions, which produced artist's books; from 1974, he operated in partnership with Helen Douglas. In 2002, Stokes moved to East Anglia to care for his mother. He redirected his focus to sculpture, which he exhibited at the Kettle's Yard open house in 2008 and at shows in various galleries.
 Passage 2:Peter Jackson and partner/co-writer Fran Walsh conceived the idea for The Frighteners in 1992, during the script-writing phase of Heavenly Creatures. Together, they wrote a three-page film treatment and sent it to their talent agent in Hollywood. Robert Zemeckis viewed their treatment with the intention of directing The Frighteners as a spin-off film of the television series, Tales from the Crypt (which he helped produce). Zemeckis hired Jackson and Walsh to turn their treatment into a full-length screenplay in January 1993. The husband and wife duo completed their first draft for The Frighteners in early-January 1994. Zemeckis was so impressed with their script, he decided The Frighteners would work better directed by Jackson, executive produced by Zemeckis and funded/distributed by Universal Pictures. Universal green-lighted the film to commence pre-production on a $26 million budget in April 1994. The studio also granted Jackson and Zemeckis total artistic control and the right of final cut privilege.
 Passage 3:For the 2009 season the Phillies wore black, circular "HK" patches over their hearts in memory of broadcaster Harry Kalas, who died April 13, 2009, just before he was to broadcast a Phillies game in Washington, D.C. From Opening Day through July 26, 2009, the Phillies wore 2008 World Champions patches on the right sleeve of their home uniforms to celebrate their World Series victory the season prior. After the death of Hall of Fame pitcher Robin Roberts on May 6, 2010, the Phillies wore a black patch with a white "36" on the sleeves of their jerseys in memory of Roberts for the remainder of the 2010 season.
