[EX Q]: Question: How well rated was the episode where the ninth doctor morphed into the tenth? Passage 1: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 2: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 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.

 Passage 2:"Lisa the Skeptic" is the eighth episode of The Simpsons' ninth season. It first aired on the Fox network in the United States on November 23, 1997. On an archaeological dig with her class, Lisa discovers a skeleton that resembles an angel. All of the townspeople believe that the skeleton actually came from an angel, but skeptical Lisa attempts to persuade them that there must be a rational scientific explanation. The episode's writer, David X. Cohen, developed the idea after visiting the American Museum of Natural History, and decided to loosely parallel themes from the Scopes Monkey Trial. The episode also makes allusions to actual hoaxes, such as the Cardiff Giant. 
 Passage 3:With the ascendance of Simeon I to the throne in 893, the long-lasting peace with the Byzantine Empire established by his father was about to end. A conflict arose when Byzantine Emperor Leo VI the Wise, acting under pressure from his wife Zoe Zaoutzaina and her father, Stylianos Zaoutzes, moved the marketplace for Bulgarian goods from Constantinople to Thessaloniki, where Bulgarian merchants were heavily taxed. Forced to take action, in the autumn of 894 Simeon invaded the Byzantine Empire from the north, meeting little opposition due to the concentration of most Byzantine forces in eastern Anatolia to counter Arab invasions. Informed of the Bulgarian offensive, the surprised Leo sent an army consisting of guardsmen and other military units from the capital to halt Simeon, but his troops were routed somewhere in the theme of Macedonia.The Magyars managed to defeat Simeon's army twice, but in 896 they were routed in the Battle of Southern Buh. The war ended in 896 with a great Bulgarian victory near Bulgarophygon in Eastern Thrace. The market was returned to Constantinople, and the Byzantine Emperor had to pay annual tribute to Bulgaria. More importantly, with help from the Pechenegs Simeon successfully fended off a Magyar invasion, which was coordinated with the Byzantines.
