[EX Q]: 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.
 Link Information: On 2 April 2004, it was announced that Eccleston was to play the ninth incarnation of the Doctor in the revival of the BBC science fiction television series Doctor Who, which began transmission on 26 March 2005.  Question: Did the ninth doctor or tenth doctor feature in more episodes?
[EX A]: Answer:  Tenth

[EX Q]: Passage: By the mid-1970s, Arafat and his Fatah movement found themselves in a tenuous position. Arafat increasingly called for diplomacy, perhaps best symbolized by his Ten Point Program and his support for a UN Security Council resolution proposed in 1976 calling for a two-state settlement on the pre-1967 borders. But the Rejectionist Front denounced the calls for diplomacy, and a diplomatic solution was vetoed by the United States. In 1975, the increasing tensions between Palestinian militants and Christian militias exploded into the Lebanese Civil War, involving all factions. On 20 January 1976, the PLO took part in the Damour massacre in retaliation to the Karantina massacre. The PLO and Lebanese National Movement attacked the Christian town of Damour, killing 684 civilians and forcing the remainder of the town's population to flee. In 1976 Syria joined the war by invading Lebanon, beginning the 29‑year Syrian occupation of Lebanon, and in 1978 Israel invaded South Lebanon in response to the Coastal Road Massacre, executed by Palestinian militants based in Lebanon.

[EX Q]: Passage: In June 1997, Spears was in talks with manager Lou Pearlman to join female pop group Innosense. Lynne asked family friend and entertainment lawyer Larry Rudolph for his opinion and submitted a tape of Spears singing over a Whitney Houston karaoke song along with some pictures. Rudolph decided to pitch her to record labels, which required a professional demo. He sent Spears an unused song from Toni Braxton; she rehearsed for a week and recorded in a studio with a sound engineer. Spears traveled to New York with the demo and met executives from four labels, returning to Kentwood the same day. Three rejected her, arguing audiences wanted pop bands such as the Backstreet Boys and the Spice Girls, and "there wasn't going to be another Madonna, another Debbie Gibson or another Tiffany." Two weeks later, executives from Jive Records returned calls to Rudolph. Senior vice president of A&R Jeff Fenster stated, "It's very rare to hear someone that age who can deliver emotional content and commercial appeal. [...] For any artist, the motivation—the 'eye of the tiger'— is extremely important. And Britney had that." They appointed her to work with producer Eric Foster White for a month, who reportedly shaped her voice from "lower and less poppy" delivery to "distinctively, unmistakably Britney." Spears recorded thirteen songs with White, including "Autumn Goodbye", "E-Mail My Heart", "From the Bottom of My Broken Heart", "I'm So Curious", "I Will Still Love You", "Luv The Hurt Away", "Let Me Take You There", "Soda Pop", "Thinkin' About You", "Nothing Less Than Real", "Wishing on a Falling Star" and "You Got It All". The singer also recorded a cover of Sonny & Cher's 1967 single "The Beat Goes On". White was responsible for the vocal recording and song production, while additional production was done by English electronic music group All Seeing I.
