Teacher: Now, understand the problem? Solve this instance: Question: On what day did the episode where Nardole goes on an adventure with the Doctor and Bill air? Passage 1:The church is constructed in punch-dressed sandstone ashlar, and has slate roofs with inserted skylight windows. Its architectural style is Early English. The plan consists of a four-bay nave without aisles, a two-bay chancel with a north chapel and a south vestry, and a west tower. The tower is in three stages, with clasping buttresses, and contains paired west doorways, a clock face in a diamond-shaped surround, and pairs of louvred bell openings. At the top of the tower is an embattled parapet with octagonal corner pinnacles, and there are more pinnacles at the angles of the nave. The bays of the nave are separated by buttresses, and each bay contains a corbel-table and a pair of lancet windows. The sides of the chancel also contain paired lancet windows, and the east window consists of a triple stepped lancet in a blank arch. The north chapel is gabled, and contains a wheel window. The interior has been remodelled, but originally it contained a three-sided gallery on cast iron columns.
 Passage 2: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.
 Passage 3:Robert Riabhach ("Grizzled") Duncanson, 4th Chief of Clann Dhònnchaidh, was a strong supporter of King James I (1406–1437) and was incensed by his murder at the Blackfriars Dominican Friary in Perth. He tracked down and captured two of the regicides, Sir Robert Graham and the King's uncle Walter Stewart, Earl of Atholl, as they hid above Invervack in Atholl, and turned them over to the Crown. They were tortured to death in the Grassmarket in Edinburgh on the orders of the Regent, James I's widow, Joan Beaufort (d. 1445). The Collins Scottish Clan & Family Encyclopedia states that they were put to death with considerable savagery. The Robertson crest badge of a right hand upholding an imperial crown was awarded by James II (1437–60) to the 4th chief on 15 August 1451 as a reward for capturing his father's assassins. The highly unusual third supporter (below the shield) on the Robertson coat of arms, of a "savage man in chains" is in reference to the capture of Graham. It is in honour of Robert Riabhach that his descendants took the name Robertson. James II also erected the clan lands into the Barony of Struan, which formerly took in extensive lands in Highland Perthshire, notably in Glen Errochty, the north and south banks of Loch Tay and the area surrounding Loch Rannoch. None of these lands are any longer in the possession of the clan.
