You will be given a definition of a task first, then some input of the task.
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.

Question: Was the Colonel who prepared his inexperienced garrison for combat older than the fortress they were at? Passage 1:Reg Keys was an ambulance paramedic for 19 years in Solihull before retiring to Llanuwchllyn, Bala in North Wales. In the 2005 UK general election, he stood against the then Prime Minister, Tony Blair, in the Sedgefield constituency. Keys declared at the outset of the campaign that he had been a Labour Party voter and was still basically socialist, but that he was seeking election as a candidate opposed to Blair's policy on the Iraq War. He claimed that by electing him, voters could keep the Labour Party in power but with Gordon Brown as the likely Prime Minister rather than Blair. Former Independent MP Martin Bell urged the other parties to withdraw their candidates as removing a supporter of the war from office would send a message to President Bush and other World Leaders who had supported him. During the campaign, UK newspaper The Guardian's Stuart Jeffries asked Keys, "Is it difficult to be a political candidate in these circumstances, when you are still clearly grieving?", to which he replied "Yes it is. […] I feel, though, that I have a responsibility to Tom. I keep going back to the words of a widow of a man who died on the Kursk […]. She said: 'If you betray your country you are a traitor and you will go to prison. But if your country betrays you, what can you do?' I think I have an answer to that: we can use our vote to get rid of those people who betrayed my son and other men like him. That's what I want the people of Sedgefield to do."
 Passage 2:Meanwhile, at Oscarsborg Fortress near Drøbak, Colonel Birger Eriksen prepares his undermanned and inexperienced garrison for combat, while receiving reports from the outlying fortresses of incoming German ships. Early on the morning of 9 April, Eriksen spots the German cruiser Blücher entering Drøbak Sound. Despite having received no instructions from Oslo to engage, Eriksen considers the German ship to be hostile and gives the order to fire, and the fortress's guns and torpedo battery sink the Blücher. Prime Minister Nygaardsvold telephones the King, informing him of the impending invasion, and advises him to flee Oslo. The Royal Family boards a train for Hamar, where the Norwegian Parliament convenes to discuss negotiations with Germany. Bräuer meets Oslo's police chief Kristian Welhaven, his intermediary with the Norwegian Cabinet, to reassure them of his desire to negotiate; at the same time, Pohlman receives orders from Berlin to send paratroopers to Hamar to capture the King and the Cabinet. Nasjonal Samling leader Vidkun Quisling proclaims himself Prime Minister over the national radio, and calls upon the Norwegian people to accept the German occupation forces. Bräuer receives instructions from Hitler himself to go directly to the King and convince him to recognise Quisling's government, though Bräuer is convinced that neither Haakon nor the Cabinet will accept this.
 Passage 3:Apart from major religious and national holidays, the bell was rung on some of the most significant moments in the history of Poland, including the German invasion of Poland on 1 September 1939, on the eve of Poland's entry into the European Union on 30 April 2004, on the occasion of each visit by Pope John Paul II, and after the plane crash which killed President Lech Kaczyński and dozens of other high-ranking officials on 10 April 2010. It also tolled during funerals or reburials of several great Poles, such as Adam Mickiewicz (1900), Marshal Józef Piłsudski (1935), General Władysław Sikorski (1993), Pope John Paul II (2005), and Lech Kaczyński with his wife (2010). It rung defiantly on Polish national holidays in the times of partitions (1795–1918) and under the communist regime (1945–1989), thus reinforcing its role as a national symbol
