PROBLEM: 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?

SOLUTION: Answer:  Tenth

PROBLEM: Passage: Culberson was signed by the Dodgers in November 2015 and invited to spring training, where he impressed new Dodgers manager Dave Roberts. After an injury to Howie Kendrick opened a spot for him, Culberson made the Dodgers 2016 Opening Day roster. He was designated for assignment in July and optioned to the Oklahoma City Dodgers, then recalled a month later. Culberson ended the big club's final home game of the season with a walk-off home run against former Rockies teammate Boone Logan, clinching the Dodgers' fourth consecutive National League West division title. He played in 34 games for Los Angeles, hitting .284 and in 70 games for Oklahoma City, hitting .260. He had no hits in seven at-bats with two strikeouts in the 2016 National League Division Series. He was outrighted to the minors and removed from the 40-man roster on December 9, 2016. He was assigned to Oklahoma City to begin the season. He remained in the minors for the conclusion of the AAA season, hitting .250 in 108 games and returned to the majors with the Dodgers on September 4. In 15 games for the Dodgers, he hit .154 with two hits in 13 at-bats. When starting shortstop Corey Seager was left off of the 2017 NLCS roster because of a back injury, Culberson was added to the post-season roster. He appeared in all five games of the series, with five hits in 11 at-bats for a .455 average. In the 2017 World Series, Culberson had three hits in five at-bats, including his first career post-season home run, which he hit off Chris Devenski of the Houston Astros in the 11th inning of Game Two.
 Link Information: The Los Angeles Angels of Anaheim selected Kendrick in the tenth round of the 2002 Major League Baseball draft. Question: Who had been playing professional ball longer by the year Culberson was signed by the Dodgers, Corey Seager or Howie Kendrick?

SOLUTION: Answer: Howie Kendrick

PROBLEM: Passage: In 1560 or 1561 Buchanan returned to Scotland, and by April 1562 was installed as tutor to the young Mary, Queen of Scots, who read Livy with him daily. Although he had remained Catholic throughout his support of the new learning and his strident criticism of the vices of the clergy, he now openly joined the Protestants Reformed Church and in 1566 was appointed principal of St Leonard's College, St Andrews, by the Earl of Moray. Two years before, he had received from the queen the gift of the revenues of Crossraguel Abbey. Though a layman, he was made Moderator of the General Assembly of the Church of Scotland in 1567. He had sat in the assemblies from 1563. He was the last lay person to be elected Moderator until Alison Elliot in 2004, the first female Moderator.
