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 Input: Question: How old was Alexander's wife when they got married? Passage 1:The Irish government under outgoing Taoiseach Enda Kenny expressed concerns that a parliamentary deal between a British government and the DUP could put the Northern Ireland peace process at risk, a view also expressed by Sinn Féin politicians Gerry Adams and Gerry Kelly, Labour MP Yvette Cooper and former Downing Street Director of Communications Alastair Campbell. This opinion was, however, rejected by the Conservative leadership and former Secretary of State for Northern Ireland, Theresa Villiers, as well as by former Labour minister Caroline Flint who suggested that Gordon Brown may have sought an agreement with the DUP in 2010. The Conservative peer and former UUP First Minister of Northern Ireland, David Trimble, described claims that an agreement would put the peace process at risk as "scaremongering". On 13 June former Conservative Prime Minister John Major publicly urged May to govern without DUP support and not pursue a deal, on the grounds that an agreement could "damage" the "fragile" Northern Ireland peace process, suggesting the government must remain 'impartial'. Major himself had an agreement with the Unionist MPs of the UUP when in power and during peace negotiations in Northern Ireland, though not with the more hardline and socially-conservative DUP. On 15 June Sinn Féin's Gerry Adams met with Theresa May, telling her that he thought she was in breach of the Good Friday Agreement. This has been disputed by one of the UUP's negotiators for the Belfast Agreement.
 Passage 2:He testified as an expert witness about Russian interference in the 2016 United States elections, in a March 30, 2017 hearing before the United States Senate Select Committee on Intelligence. His testimony before the Senate Intelligence Committee was well received, and made multiple headlines. Slate referred to him in a headline as: "Clint Watts, Testifier Extraordinaire", and "The star of March’s Senate Intelligence Committee hearing". CNN profiled him after the testimony in a piece "Russia investigation: Who is Clint Watts", where it was noted he gained knowledge in the field of Russian cyber hacking methods, after himself being a target in 2015 following his "Trolling for Trump" article; the FBI notified the Foreign Policy Research Institute of the attack. Salon compared his testimony "follow the trail of dead Russians" to John Dean's statement about "a cancer on the presidency". This phrase in testimony by Watts was highlighted by the media, including CBS News, The American Interest, and The Oregonian. U.S. Senator Ron Wyden found the comment important to his investigation. Mark Shields of PBS NewsHour found his testimony "compelling", and CNN called it "blistering". Jennifer Rubin wrote for The Washington Post that his testimony "laid out the most comprehensive look at the array of tools Russia used to influence our election". After his testimony, he appeared on NBC's Meet the Press and explained ways the U.S. can better respond to cyberwarfare.
 Passage 3:Ancient historians, as well as modern ones, have also written on Alexander's marriage to Roxana the beautiful [Persian]n woman. Robin Lane Fox writes, "Roxana was said by contemporaries to be the most beautiful lady in all Asia. She deserved her name of Roshanak, meaning 'little star', (probably rokhshana or roshana which means light and illuminating) in Persian. Marriage to a local noble's family made sound political sense, but contemporaries implied that Alexander, aged 28, also lost his heart. A wedding-feast for the two of them was arranged high on one of the Persian rocks. Alexander and his bride shared a loaf of bread, a custom still observed in Turkestan. Characteristically, Alexander sliced it with his sword. Ulrich Wilcken writes, "The fairest prize that fell to him was Roxana, the daughter of Oxyartes, in the first bloom of youth, and in the judgment of Alexander's companions, next to Stateira the wife of Darius, the most beautiful woman that they had seen in Asia. Alexander fell passionately in love with her and determined to raise her to the position of his consort."

Example Input: Question: Is the racecourse where Roaring Riva began his racing career at and the location where he moved up in class for Group 1 Phoenix Stakes located in the same country? Passage 1:Emanuel Nobel was a very forward-looking businessman, just like his father, who had instigated the construction of Russia's first pipeline and the world's first oil tanker in 1878, as well as the world's first railway tank cars in 1883. On 16 February 1898 Emanuel signed a licence agreement in Berlin with Rudolf Diesel, after having heard Diesel describing his new engine in a public lecture. The agreement allowed Nobel to build the world's first diesel engine plant in St Petersburg, and the engines were used to propel Branobel's fleet of oil tankers. Emanuel led Baku to a dominating role in the global oil industry and Branobel activities soon developed throughout the Caspian Sea, operating also in Grozny and Dosser.
 Passage 2:Dean Clark took over as head coach shortly after James' resignation, and led the 1997–98 Hitmen to a remarkable turnaround. The team improved to a 40–28–4 record and first-place finish in the Central Division, qualifying for the playoffs for the first time in franchise history. They defeated the Saskatoon Blades and Swift Current Broncos to reach the Eastern Conference final before falling to the Brandon Wheat Kings. Clark was awarded the Dunc McCallum Memorial Trophy as the WHL's top coach, and also won the Canadian Hockey League's Brian Kilrea Coach of the Year Award. Calgary improved to 51–13–8 in 1998–99, finishing one point ahead of the Kamloops Blazers for the regular season title. Led by Brad Moran, Pavel Brendl and goaltender Alexandre Fomitchev, the Hitmen lost just five games in the playoffs en route to their first league championship. They won the title at home before a WHL playoff record crowd of 17,139. They became the first Calgary-based team to qualify for the Memorial Cup since the Calgary Canadians won the 1926 title.
 Passage 3:Roaring Riva began his racing career by winning a maiden race over five furlongs at Windsor Racecourse and then followed up by taking a minor event over six furlongs at the same track. In early July he was sent to York Racecourse to contest the Black Duck Stakes and finished second, beaten half a length by Nomination, a colt who went on to beat Green Desert in the Richmond Stakes. The colt was then sent to Ireland and moved up in class for the Group 1 Phoenix Stakes over six furlongs on soft ground at Phoenix Park Racecourse. Ridden by Ray Cochrane he started the 4/1 second favourite behind the highly regarded, but previously unraced Tate Gallery, with the best-fancied of the other eleven runners being the unbeaten filly Sherkraine, Devil's Run and Mr John. Roaring Riva was among the leaders from the start, went to the front two furlongs out and held off the challenge of the filly So Directed to win by three quarters of a length. Laing recalled that it was "quite a day. We had private planes, champagne, the lot!"
