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: How long after the church was sacked during the Napoleonic Wars did the war begin when the church was still in military use? Passage 1:The incumbent President of the United States, Barack Obama, a Democrat and former U.S. Senator from Illinois, was first elected to the presidency in 2008, running with U.S. Senator Joe Biden of Delaware. Defeating the Republican nominee, Senator John McCain of Arizona, with 52.9% of the popular vote and 68% of the electoral vote, Obama succeeded two-term Republican President George W. Bush, the former Governor of Texas. Obama and Biden were reelected in the 2012 presidential election, defeating former Massachusetts Governor Mitt Romney with 51.1% of the popular vote and 61.7% of electoral votes. Although Barack Obama's approval rating in the RealClearPolitics poll tracking average remained between 40 and 50 percent for most of his second term, it has experienced a surge in early 2016 and reached its highest point since 2012 during June of that year. Analyst Nate Cohn has noted that a strong approval rating for President Obama would equate to a strong performance for the Democratic candidate, and vice versa.
 Passage 2:The church was founded by the Franciscan Order in 1304 but it was not consecrated until 1459, when Pope Pius II performed the ceremony. Suppressed in 1782, it was sacked in 1797, during the Napoleonic Wars, and turned into an arsenal in 1811. Still in military use when World War II began, it was devastated by bombardment during the war. The Cappella Gonzaga, with its frescoes depicting the life of St. Louis of Toulouse ( ), was saved and recently restored. These frescoes were supposed to have been painted by Serafino de' Serafini, an artist who was active in Modena during the 14th Century. The church was reconstructed in Romanesque and Gothic styles. Now visible are some of the original frescoes depicting St. Francis Receives the Stigmata by Stefano da Verona. Andrea Mantegna's work St. Bernardino of Siena between Two Angels was originally here but it is now at the Pinacoteca di Brera in Milan, Italy.
