Question: How old was the actor who played the Ninth Doctor at the end of his run? Passage 1: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.
 Passage 2:In 1902 Vice President Theodore Roosevelt requested that Marshall Bond assist Roosevelt's cousin Leila's husband Edward Reeve Merritt, a Bond friend, to help a group of Boer refugees purchase ranchland and establish a colony in Mexico. Judge Hiram Bond's cattle dealing at Villa Park Ranch near Denver had included some previous experience with purchases from and sales to ranchers in Mexico. After Marshall Bond and Edward Reeve Merritt met and negotiated with José Yves Limantour and other federal officials in Mexico City and visited various potential sites, they bought a large ranch Hacienda Humboldt from Governor Luis Terrazas on the Rio Conchos in the municipality of Julimes near Delicias, Chihuahua. For more, see Creel-Terrazas Family. The Boers managed to farm there for about fifteen years, until they were displaced as farmers and managers by native Mexicans who were supported by populist labor agitators.
 Passage 3:Cross began his career at Walsall, who finished 12th in the Third Division in 1966–67 under the stewardship of Ray Shaw. New boss Ron Lewin then took the "Saddlers" to a seventh-place finish in 1967–68. After a 13th-place finish in 1968–69, Bill Moore returned to lead Walsall to 12th place in 1969–70. Cross played just 12 league games in his four years at Fellows Park. He joined Gordon Lee's Port Vale in July 1970. He made his debut on 5 September, in a 1–0 win over Preston North End at Vale Park. He played 42 Third Division games in the 1970–71 season, and scored his first goal in the Football League on 2 January, in a 2–1 win over Doncaster Rovers at Belle Vue. He was an ever-present in the 1971–72 season, playing all 46 league and five cup games. He made 40 appearances in the 1972–73 season, and ended a series of 134 consecutive appearances from his debut in March 1973 when he wrenched his left knee. He recovered from this injury to play just two games in the 1973–74 campaign, but then he injured his knee ligaments in October 1973 and was out of action for 17 months. He managed to play just two games in the 1974–75 season, and was handed a free transfer in May 1975 by new manager Roy Sproson. He went on to play for Southern League side Nuneaton Borough. Upon his retirement as a player, he became a School of Excellence coach at Stoke City. He later went on to become a teacher for 25 years.
