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: Who was younger the year Grace accidentally cut her finger off, Christopher Hobbs or Mark Ferguson? Passage 1:The Egyptian collection consists of about fifty itens, including some objects which stand out in the context of Brazilian museums, due to their quality and rarity. Since these objects are not related to official archeological excavations, their exact place of origin remains largely unknown. The collection includes a number of large pharaonic statuary, in which a head of a Pharaoh in a nemes headdress is the centerpiece. Among the funerary itens, there is a coffin mask with encrusted glass eyes dating back to the 17th Dynasty, and other pieces which reflect the importance of animals in Egyptian rituals, such as a coffin of a mummified cat from the Ptolemaic period. The collection also includes reliefs and fragments of architectural decoration, such as a prominent temple bas-relief of a goddess with the body of a woman and the head of a lioness, dating back to the 3rd Intermediate Period.
 Passage 2:With the Treaty of Pozvol, concluded in 1557, the Livonian Confederation had turned to Poland-Lithuania for protection, triggering Ivan IV of Russia's intervention in what was to become the Livonian War. In 1558, Ivan IV had conquered the Dorpat (Tartu) area, annihilating the Bishopric of Dorpat. With the Treaty of Vilnius of 31 August 1559, Gotthard von Kettler, Grand Master of the Livonian Order, had put the order's lands under protection of Polish king and Grand Duke of Lithuania, Sigismund II Augustus. The order ceded about one seventh of its territory, allowed Sigismund to garrison its most important castles, and agreed to share with him any conquests made from Ivan IV. The alliance was intended to neutralize the imminent threat of annexation of the order's lands by Russia, yet despite earning military support from Polish-Lithuanian chancellor Mikołaj "the Black" Radziwiłł, Kettler was defeated in Ergeme (Ermes, 1560) and unable to prevent the occupation of most of Livonia by Russian forces. After the treaty, the disintegrating order agreed to secularization if necessary, and since Sigismund was reluctant to support it militarily, continued its search for a protector at the courts of Denmark-Norway and the Holy Roman Emperor.
 Passage 3:Following the departure of Simon Hilton-Jones (John Wraight) from Shortland Street clinic, Chief Executive Officer Michael McKenna (Paul Gittins) decided to poach Grace from his rival Sir. Bruce Warner's (Ken Blackburn) clinic. Bruce was devastated to hear Grace was leaving and made a hugely public announcement of his love for her in the Kennedy's bar, to which she rejected him. Grace began work at Shortland Street though her naturally flirtatious manner led many to believe she was having an affair with both Bruce and Michael - even Michael's wife Alex (Liddy Holloway). Grace dated Darryl Neilson (Mark Ferguson) but soon came to realize he was stealing her eggs and selling them off, leading to a break up. She subsequently had a brief relationship with Zac Smith (Mike Edward) but ended up deciding to flee Ferndale after reconciling with Darryl. However Darryl's dead body was found in the Auckland harbor. The following year Grace fell in love with Lionel Skeggins (John Leigh) but instead took up with Minnie's (Katrina Devine) father, Ryan Birch (Robert Harte). However she soon came to realize Ryan had in fact raped her best friend Ellen (Robyn Malcolm) several years beforehand and they broke up. Grace finally got together with Lionel but the romance was short lived and she moved onto Frank Malone (Christopher Hobbs). In 1997 whilst cooking, Grace accidentally severed her finger however luckily managed to reattach it. Shortly after, Grace got a job in Australia and departed Ferndale. The following year, Ellen visited Grace and returned with the news that she had become a mother to two twin boys. Grace returned to Ferndale in October 2013 to audit the hospital following the CEO, Chris Warner's (Michael Galvin) health concerns. It soon transpired that Grace had been through a devastating break up and was in desperate need to be a mother. She made an agreement with Chris that would see the two have sex without complications so as to have a child. Grace then realise that she has feelings for Chris and then tried to stop his wedding to Rachel McKenna. She then leave Ferndale after Chris couldn't return her feelings and she leaves after she lied that she had a miscarriage.
