Question: Passage: Relations between the people of Afghanistan and India traces to the Indus Valley Civilisation. Following Alexander the Great's brief occupation, the successor state of the Seleucid Empire controlled the region known today as Afghanistan. In 305 BCE, they ceded much of it to the Indian Maurya Empire as part of an alliance treaty. The Mauryans brought Buddhism from India and controlled the area south of the Hindu Kush. Their decline began 60 years after Ashoka's rule ended, leading to the Hellenistic reconquest of the region by the Greco-Bactrians. Much of it soon broke away from the Greco-Bactrians and became part of the Indo-Greek Kingdom. The Indo-Greeks had been defeated and expelled by the Indo-Scythians in the late 2nd century BCE. Much of Afghanistan has been influenced by Buddhist, Hindu and Zoroastrian cultures until the arrival of Islam in the 7th century. But despite many Afghans converting to Islam, the Muslims and Hindus lived side by side.

Question: 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?

Answer: Answer:  Tenth


Question: Passage: Thomson, a wing half, started his career with Thornton Rangers in his native Fife, before moving to Dundee, where he played for four years. In 1929 he moved to Everton. His Everton career had an inauspicious start, with the club suffering relegation in his first season. The following season, he gained a Second Division winners medal as Everton made an immediate return to the top flight, and then added a First Division medal in 1932 as Everton became champions. Later that year he made his international debut, representing Scotland in a 5–2 home international defeat against Wales, though this was to be his only international appearance. He played in the 1933 FA Cup Final, helping Everton to a 3–0 win against Manchester City. Later in his time at Everton first team appearances became more uncommon for Thomson as he was displaced from the team by Joe Mercer. Thomson retired from playing in 1938, having made 299 appearances for Everton, in which he scored five goals.
