Input: Question: How old was the person who escaped to Africa when Cleopatra ascended to the throne? Passage 1:Shields played first for Leicestershire in 1906 and became a regular player as wicketkeeper in 1907, thereafter playing fairly regularly until the end of the 1910 season. He succeeded Sir Arthur Hazlerigg as captain for the 1911 season with an extremely poor side: Vivian Crawford, a mainstay of the batting, had departed for Sri Lanka and fast bowler Thomas Jayes was able to play only two matches because of the tuberculosis that led to his early death; in addition, Ewart Astill, the other reliable bowler of previous years, lost form so badly that he lost his place in the team. Wisden Cricketers' Almanack noted that "no one but a sanguine man of happy disposition could have gone through the season at all complacently". In 24 first-class matches, Leicestershire lost 18 times and gained just a single victory, though they did not finish bottom of the County Championship because Somerset's record was even worse. The single victory was one of the sensational matches of the season: Yorkshire, in the match after Wilfred Rhodes' benefit match, were shot out for just 47 by John King's left-arm medium pace and Leicestershire won by an innings.
 Passage 2:Caesar crossed the Rubicon accompanied by the XIII Legion to take power from the senate in the same way that Sulla had done in the past. Formally declared an enemy of the state, Caesar pursued the Senatorial party, now led by Pompey, who abandoned the city to raise arms in Greece. Cato was sent to Sicily to secure control of the grain supply. After securing control of Italy, Caesar sent the praetor Curio with four legions to Sicily. Cato's garrison was insufficient to withstand a force of this magnitude, he abandoned the island and went to Greece to join Pompey. After first reducing Caesar's army at the siege battle of Dyrrhachium, where Cato commanded the port, the army led by Pompey was ultimately defeated by Caesar in the Battle of Pharsalus (Cato wasn't present during the battle, Pompey had left him in command of Dyrrhachium). Cato and Metellus Scipio, however, did not concede defeat and escaped to the province of Africa with fifteen cohorts to continue resistance from Utica. Caesar pursued Cato and Metellus Scipio after installing the queen Cleopatra VII on the throne of Egypt, and in February 46 BC the outnumbered Caesarian legions defeated the army led by Metellus Scipio at the Battle of Thapsus. Acting against his usual strategy of clemency, Caesar did not accept surrender of Scipio's troops, but had them all slaughtered.
 Passage 3:For the tenth series, which follows the two specials, Nardole remains the Doctor's assistant. When the series begins, with "The Pilot" (2017), the pair were based in a university in Bristol, where Nardole attempted to keep the Doctor to his oath to guard an alien vault beneath the university. He is concerned about the Doctor taking on Bill Potts (Pearl Mackie) as a new travelling companion, maintaining that it amounts to him abandoning his post. Nardole is ultimately dragged on an outer space adventure with the Doctor and Bill in "Oxygen". The subsequent episodes of "Extremis", "The Pyramid at the End of the World" and "The Lie of the Land", following a story arc over the three episodes, establish that Nardole came to assist the Doctor on instructions left by River Song before she died, and has taken it as his mission to keep the Doctor in line as the last request of River Song, to the point that he refers to himself as "the only person legally qualified to kick the Doctor's arse". He formally joined the Doctor after the Doctor took an oath to guard his Time Lord friend and arch-enemy Missy (Michelle Gomez) for a thousand years. In the same story, Nardole narrowly escapes a deadly bacterial infection due to his alien biology, and assists Bill and the Doctor in restoring free will to the Earth after history had been rewritten by the menacing alien "Monks". In several following episodes, Nardole repeatedly shows his resourcefulness and adaptability as he joins the Doctor and Bill on other trips, even once working with Missy to repair the TARDIS after it returns to Earth with Nardole inside it while leaving the Doctor and Bill on Mars in the Victorian era ("Empress of Mars"). In the series finale, "World Enough and Time"/"The Doctor Falls", the Doctor's crew and Missy react to a distress call on board a Mondasian ship, which results in Bill being shot through the heart and converted into a Cyberman, due to the machinations of Missy's past incarnation, the Master (John Simm). They escape the immediate clutches of the Cybermen due to Nardole commandeering a shuttle, which he pilots into higher levels of the colony ship. The ship is so large that several simulated countrysides exist within as solar farms, with dozens of villagers. In battle with the Cybermen, Nardole repeatedly proves his computer and combat talents, rigging powerful explosions throughout the countryside. When the Doctor realises that to defeat the Cybermen he must destroy a whole level of the ship, he instructs Nardole to take the villagers to safety on another floor. Nardole does so, unsure if he will ever see the Doctor again, and knowing that the Cybermen will one day return to convert the human population. Lucas reprises the role briefly in "Twice Upon a Time", playing an avatar of Nardole made from Nardole's memories at the time of his death. He hugs the Doctor and wishes him farewell before his pending regeneration. In Paul Cornell’s novelisation of the story, it is revealed that the Cybermen stopped being a threat not long after the Doctor left and Nardole lived to an old age with several wives and children.
