In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Example: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Problem: Question: How old is the actor who played Missy's past incarnation now? 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: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.
 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.
