Question: What was the name of Telfer's maternal grandfather? Passage: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.

Question: How old was the actor who took over the role of the eleventh doctor, at that time? Passage:The regeneration of the Ninth Doctor into the Tenth at the end of "The Parting of the Ways" (2005) used computer effects to morph Christopher Eccleston into David Tennant. In the episode of Doctor Who Confidential accompanying the episode "Utopia" (2007), where the same effect is used for the Master's regeneration, it is stated that the production team decided that this would be a common effect for all future Time Lord regenerations, rather than each regeneration being designed uniquely at the whim of the individual director. This style of transition is seen again in "The Stolen Earth"/"Journey's End" (2008) both when the Doctor undergoes an aborted regeneration, and when his hand spawns a clone in the second part; in The End of Time (2010) during which Matt Smith took over the role as the Eleventh Doctor; in "The Impossible Astronaut" when the Doctor is shot twice and seemingly killed; in "Day of the Moon" when a young girl regenerates; and in "Let's Kill Hitler" when Mels (Nina Toussaint-White) is shot and regenerates into River Song (Alex Kingston). "The Night of the Doctor" and "The Day of the Doctor" subsequently use the effect to show the Eighth Doctor and War Doctor's regenerations respectively. The Eighth Doctor's regeneration into the War Doctor uses steady beams of light as opposed to the flame effect used for other revived series regenerations. In the Series 10 episode "The Lie of the Land", the Twelfth Doctor fakes a regeneration as part of a plan to test if Bill still has free will. The effect used is consistent with the one used in the modern series, with the Doctor's hands glowing and emitting regeneration energy before he enters full regeneration. However, as the regeneration was not real, it did not use up a regeneration and the Doctor did not change bodies.

Question: How many members make up the Coodbeen Champions along with Greg Champion? Passage:Football humorists the Coodabeen Champions have written many songs about the sport since the Coodabeens Footy Show first aired in 1981. Greg Champion, the team's main songwriter, wrote the 1994 hit "That's the Thing About Football". Other titles include "VFL Park in the Dark", "Deep in Our Hearts Everyone Barracks for Fitzroy", "Matty Lloyd Throws Grass in the Air", "Knee Reconstruction" and "Dermott Brereton is a Hood". In 1994, actor Eric Bana released the album Out of Bounds in which he lampoons popular football identities. "Out of Bounds" is also a song by bawdy balladeer Kevin Bloody Wilson, parodying personalities on The Footy Show. In 1981, television's Ugly Dave Gray proposed a new club song with "Come on Fitzroy". Comedian Austen Tayshus released "Footyana" in 1999, a spoken-word single in the style of "Australiana" (1983). "Kicking the Footy with God" by The Bedroom Philosopher is about Gary Ablett, Sr. ("God"), released on his 2005 debut album In Bed with My Doona. Sidewinder's Nick Craft penned "It's a Draw" in response to the 2010 AFL Grand Final.
