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: What material was the item woven for Athena every four years made of? Passage 1:For 2011, Leimer moved to the Rapax team alongside Julián Leal. He finished fifth overall in the Asia series, and then proceeded to take his second category win in the main series. As was the case the previous year, the victory came in the sprint race at the Catalunya circuit, and he again set the fastest lap in the process, although on this occasion he owed his reverse-grid pole position to Romain Grosjean's disqualification from the feature race. Another haul of points at Monza saw him improve to 14th position in the championship standings. He also won the feature race of the non-championship event held at the Yas Marina Circuit. Leimer switched to the Racing Engineering team for 2012, where he partnered Nathanaël Berthon. Despite failing to win a race during the season, his improved consistency, consisting of six podium finishes, saw him improve to seventh place in the drivers' championship. Leimer took the GP2 driver's championship title in 2013, with seven podium finishes and three wins.
 Passage 2:The Panathenaea (, "all-Athenian festival") was the most important festival for Athens and one of the grandest in the entire ancient Greek world. Except for slaves, all inhabitants of the polis could take part in the festival. This holiday of great antiquity is believed to have been the observance of Athena's birthday and honoured the goddess as the city's patron divinity, Athena Polias ('Athena of the city'). A procession assembled before dawn at the Dipylon gate in the northern sector of the city. The procession, led by the Kanephoros, made its way to the Areopagus and in front of the Temple of Athena Nike next to the Propylaea. Only Athenian citizens were allowed to pass through the Propylaea and enter the Acropolis. The procession passed the Parthenon and stopped at the great altar of Athena in front of the Erechtheum. Every four years a newly woven peplos was dedicated to Athena.
 Passage 3:Greenberg had expressed the wish that he should be cremated and his remains buried, without any religious ceremony, near Mount Scopus in Palestine. The casket containing his ashes arrived in Haifa in November 1931, but the Orthodox rabbinate in Jerusalem insisted that since Jewish law prohibits cremation, it could not be buried in consecrated ground. Letters flew back and forth between London and Palestine as his son Ivan tried to resolve the impasse. In January 1932, Joe Linton, one of Weizmann's aides, suggested burying the casket in Herbert Bentwich's private garden near Mount Scopus. This would have been a nice irony since the two men had loathed one another. In any event, this solution was over-ruled by the rabbinate. By May 1932, the casket was still in the customs office in Haifa, and officials threatened to throw it out if something was not done about it. Eventually, through the combined efforts of Moshe Sharett (later Foreign Minister and Prime Minister of Israel) and Chaim Arlosoroff, both high-ranking officials in the Jewish Agency, a resting place for Greenberg's remains was found at Kibbutz Degania by the shore of the Sea of Galilee.
