Input: Consider Input: Question: Who was the Han emperor when the Xianbei killed the Xiongnu chanyu Youliu? Passage 1:In 2010, in collaboration with the actor Enrico Lo Verso and the musician Gabriele Denaro, he created the work Sensibilità Sonore, dedicated to topics such as marginalization, poverty and childhood. The following year, he produced the documentary "Il rimorso" (the remorse), a video that narrates violence against the women. The project was being projected every year during national conferences in various Italian cities and received an award for the Social Communication. The journal Fatto Quotidiano considered it as "a virtuous example that denounces the wrong". It was previewed at the Camera dei deputati della regione Lazio (Chamber of Deputies of the Region of Lazio) and introduced the conference "Lui per Lei - un ponte fra Napoli e New York" at the city Partenopea and at the municipality of Fiumincino by the iniziative of the Assesorato alle politiche sociali (Department of social policies) as well as the event "Io non ci sto più" (I am non there anymore) dedicated to the memory Eligia Ardita, a victim of a femicide act. 2013 he directed the documentary "Streghe a Pachino: Un caso giornalistico irrisolto" (Witches at Pachino: An unsolved journalistic case), recovering after 50 years, a mysterious fact initially narrated by Beppe Ferrara in 1963 that burst a war between the media, the politics and the omertà. The same year he films three special documentaries about Mario Sesti, Sergio Donati and the musician Mauro Di Domenico. He carried out interviews with personalities from the show business, created web projects, such as the ObamaStay, a project that promotes and supports the election of the American president, which received the appreciation from the Woman for Obama and from the Electionpaper, concerning the Italian elections reported by the press agencies Agi and RAI. wrote for the Sindacato Nazionale di Critica (National Syndicate of Italian Film Critics).

From 2014 he is devoted actively for the promotion of the Patrimonio Verghiano, redeveloping the historical Cunziria, the original film location of the famous Cavalleria Rusticana, directed by Franco Zeffirelli and inspiration scenery of the homonymous novel of the writer Giovanni Verga. Muscoso eventually turned the ancient village into a stage denominating it Teatro Cunziria".
 Passage 2:The Xianbei (; ) were an ancient nomadic people that once resided in the eastern Eurasian steppes in what is today Mongolia, Inner Mongolia, and Northeastern China. They originated from the Donghu people who splintered into the Wuhuan and Xianbei when they were defeated by the Xiongnu at the end of the 3rd century BC. The Xianbei were largely subordinate to larger nomadic powers and the Han dynasty until they gained prominence in 87 AD by killing the Xiongnu chanyu Youliu. However unlike the Xiongnu, the Xianbei political structure lacked the organization to pose a concerted challenge to the Chinese for most of their time as a nomadic people. After suffering several defeats by the end of the Three Kingdoms period, the Xianbei migrated south and settled in close proximity to Chinese society and submitted as vassals, being granted the titles of Dukes. As the Xianbei Murong, Tuoba and Duan tribes were one of the Five Barbarians who were vassals of the Han Chinese Western Jin and Eastern Jin dynasties, they took part in the Uprising of the Five Barbarians as allies of the Han Chinese Eastern Jin against the other four barbarians, the Xiongnu, Jie, Di and Qiang. The Xianbei were at one point all defeated and conquered by the Di Former Qin empire before it fell apart at the Battle of Fei River at the hands of the Eastern Jin. The Xianbei later founded their own states and reunited northern China as the Northern Wei. These states opposed and promoted sinicization at one point or another but trended towards the latter and had merged with the general Chinese population by the Tang dynasty.
 Passage 3:For the rest of the 1970s, Schneider opted to star in small-budgeted, independent European productions, such as the little-seen Swiss period piece Violanta (1976, with a young Gérard Depardieu), and three consciously feministic works: the Italian production I Belong to Me (Io Sono Mia) (1978, with Stefania Sandrelli); the graphic, disturbing Memoirs of a French Whore (French title: La Dérobade) (1978, alongside Miou-Miou, and for which Schneider was nominated for Best Supporting Actress at the 1980 5th César Awards); and the lesbian Dutch drama A Woman Like Eve, directed by Nouchka van Brakel, where Schneider plays the bohemian love interest of conflicted Monique van de Ven who is married to and has children with Peter Faber.

Input: Consider Input: Question: What was the episode number where a doctor faked their regeneration? 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.

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.
