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 beginning of the war did Silatch secretly arrive in Kotka? Passage 1:The present-day Angels franchise began play as the Los Angeles Angels in . Owned by actor Gene Autry and his wife Jackie, they played their inaugural season at Wrigley Field in South Los Angeles (not to be confused with the Chicago stadium of the same name). They moved to Dodger Stadium the following season, becoming tenants of the National League's Los Angeles Dodgers for four seasons. During the season, Gene Autry struck a deal with the suburban city of Anaheim on a new stadium for the Angels. The team changed its name to California Angels late in the season, as they were the only American League team in the state at the time, and moved to the city-owned Anaheim Stadium in . They would play under this moniker for over 30 seasons.
 Passage 2:The road follows an embankment close to the edge of The Wash, and at Walpole Cross Keys it enters Norfolk and the district of King's Lynn and West Norfolk. The £3.14 million West of Kings Lynn - County Boundary section was opened on 14 December 1982 by Lynda Chalker, Baroness Chalker of Wallasey. In Terrington St Clement, there is a crossroads at Balsam Field, for Tilney High End to the right, at which there is the African Violet Centre with a cafe. From this point all the way to the A47 junction, the road is the parish boundary between Clenchwarton to the north, and Tilney All Saints to the south. The former route passed through Terrington St Clement, Clenchwarton and West Lynn. The improved follows the former Spalding to South Lynn, part of the Midland and Great Northern Joint Railway (M&GN), which closed on 2 March 1959. Whilst the A17 has a chequered accident record, not a single passenger was killed on this former railway. It meets the A47 at the start of the King's Lynn bypass at what’s known as the “Pullover Roundabout”.
 Passage 3:On 4 May 1918, in the aftermath of the Finnish Civil War, Silatch arrived secretly in Kotka, Finland, to evacuate remaining members of the Finnish Red Guard. However, she was confiscated by the Finns and joined the Finnish icebreaker fleet as Ilmarinen, after the legendary hero from Kalevala. In December 1919 she was sent to Koivisto to assist three Finnish torpedo boats, C1, C2 and C3 that had been surrounded by ice some thick. The 150-ton torpedo boats had participated in the British campaign in the Baltic, and Admiral Walter Cowan had demanded that the Finnish squadron patrolling the area had to stay until the British forces had withdrawn. Despite the efforts of Ilmarinen, the weak-hulled torpedo boats were crushed by the ice, and the newly founded Finnish Navy lost one fifth of its ships. After the winter of 1919 Ilmarinen was laid up until she was returned to the Soviet Union according to the Treaty of Tartu. In turn the Soviets gave back the Finnish icebreaker Avance. The name Ilmarinen was later given to a Finnish coastal defence ship launched in 1931.
