[EX Q]: Question: How old was Cam Kirby's great grandfather when the American civil war ended? Passage:Born in Calgary. Kirby's great grandfather Charles Kirby (18051870) came to Canada as a soldier in a regiment from Yorkshire, England at the time of the Rebellion of 1837 in Upper Canada and settled in Whitby. His son Joseph Kirby (18441937) enlisted as mercenary in the 184th Regiment of New York State Infantry of the Union Army during the American Civil War and returned to Canada in 1865 and joined the Ashberminam Company of Volunteers during the Fenian Raids of 1866. In 1882 he applied for a homestead in the N.W.T. situated near what is now the town of Fleming (Sask.). Kirby's father William John Kirby (18661964) moved further west in 1885, initially as a lumberjack in Albert Canyon, worked as an agent for the Dominion Express in Vancouver, British Columbia, and later in Calgary where Cameron Kirby was born in 1909. In 1911 William Kirby set up as a merchant in Lochairn, later named at his instigation Rocky Mountain House after the Hudson's Bay Fort built nearby on the North Saskatchewan River in 1799. There he opened a dry goods store and became postmaster and eventually the town's Reeve. In 1917 when Cameron Kirby was eight years old his mother died and he was sent by his father to live with relatives. Kirby graduated from high school in Hanna, Alberta and then attended the University of British Columbia graduating with a Bachelor of Arts in 1930 before attending graduate school at the University of Alberta.

[EX A]: Kirby's great grandfather Charles Kirby (18051870) came to Canada as a soldier in a regiment from Yorkshire, England at the time of the Rebellion of 1837 in Upper Canada and settled in Whitby

[EX Q]: Question: What role did the actor who had played the ninth doctor take after his time on the show? 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.

[EX A]: 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
