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 many people were employed by NASA the year Kepler was launched? Passage 1:The Kepler spacecraft is a NASA telescope equipped with photometric equipment. Launched in 2009, Kepler continuously watches 156,000 stars in a small area. A team of astronomers, hoping to learn more about hot jupiter planets and brown dwarfs, selected four F-type stars from the Kepler Input Catalog flagged as host to a Kepler Object of Interest (a transiting object that could possibly be a planet). Using three quarters of Kepler's data, the science team conducted a follow-up investigation in using the SOPHIE échelle spectrograph at the Haute-Provence Observatory in southern France, observing stars Kepler-40, Kepler-39, KOI-552 and KOI-410. Of these, conclusive evidence of a planet orbiting KOI-410 could not be found, and KOI-552 was found to be a binary star with an M-type companion. The Hot Jupiter KOI-428b was the first of these four to be confirmed.
 Passage 2:After publishing the plays Weekend (1968) and An Evening With Richard Nixon (1972) and the novel Two Sisters: A Novel in the Form of a Memoir (1970), Vidal concentrated upon the essay and developed two types of fiction. The first type is about American history, novels specifically about the nature of national politics. About those historical novels, the critic Harold Bloom said that "Vidal's imagination of American politics ... is so powerful as to compel awe". The historical novels formed the seven-book series, Narratives of Empire: (i) Burr (1973), (ii) 1876 (1976), (iii) Lincoln (1984), (iv) Empire (1987), (v) Hollywood (1990), (vi) Washington, D.C. (1967) and (vii) The Golden Age (2000). Besides U.S. history, Vidal also explored and analyzed the history of the ancient world, specifically the Axial Age (800–200 B.C.), with the novel Creation (1981). The novel was published without four chapters that were part of the manuscript he submitted to the publisher; years later, Vidal restored the chapters to the text and re-published the novel Creation in 2002.
 Passage 3:Born into the Bhatt family, she is the daughter of filmmaker Mahesh Bhatt and actress Soni Razdan. After making her acting debut as a child in the 1999 thriller Sangharsh, Bhatt played her first leading role in Karan Johar's teen drama Student of the Year (2012). She went on to establish herself with starring roles in several films produced by Johar's studio Dharma Productions, including the romances 2 States (2014), Humpty Sharma Ki Dulhania (2014), and Badrinath Ki Dulhania (2017); and the coming-of-age drama Dear Zindagi (2016). Bhatt won the Filmfare Critics Award for Best Actress for playing a kidnapping victim in the road drama Highway (2014), and two Best Actress awards at the ceremony for playing a Bihari migrant in the crime drama Udta Punjab (2016) and a spy in the thriller Raazi (2018). The latter emerged as one of Hindi cinema's biggest-earning female-led films, and her highest-grossing release came with the musical drama Gully Boy (2019).

Example Input: Question: Who was the MVP of the All-Star Game that Pearson played in? Passage 1:Pearson's trade to the New York Yankees was initially unpopular among fans, with Joe McCarthy receiving heavy criticism for dealing Allen—who had a 13–6 record in 1935—for Pearson. However, Pearson repaid his manager's faith in him by churning out the best statistical year in his career. His .731 winning percentage (19–7 record) was third best in the AL; he finished fifth in ERA (3.71) and strikeouts (118) and sixth in wins, though he also recorded the third-highest number of walks in the AL with 135. His performance during the first half of the season resulted in him being selected for the 1936 All-Star Game, though he did not pitch in it. In the postseason, the Yankees advanced to the World Series, where they defeated the New York Giants 4–2. In Game 4, Pearson—who insisted on being included in the rotation even after falling ill with pleurisy just before the Series—limited the Giants to just two runs while striking out seven in a complete game win. Offensively, he managed to get two hits, including a double. The 5–2 victory ended Carl Hubbell's streak of 17 consecutive regular and postseason wins.
 Passage 2:The North Irish Horse is a yeomanry unit of the British Territorial Army raised in the northern counties of Ireland in the aftermath of the Second Boer War. Raised and patronized by the nobility from its inception to the present day, it was one of the first non-regular units to be deployed to France and the Low Counties with the British Expeditionary Force in 1914 during World War I and fought with distinction both as mounted troops and later as a Cyclist Regiment, achieving 18 battle honours. The regiment was reduced to a single man in the inter war years and re-raised for World War II, when it achieved its greatest distinctions in the North African and Italian campaigns. Reduced again after the Cold War, the regiment's name still exists in B (North Irish Horse) Squadron, the Scottish and North Irish Yeomanry and 40 (North Irish Horse) Signal Squadron, part of 32 Signal Regiment.
 Passage 3:Timon of Phlius ( ; , , ; BC – c. 235 BC) was a Greek Pyrrhonist philosopher, a pupil of Pyrrho, and a celebrated writer of satirical poems called Silloi (). He was born in Phlius, moved to Megara, and then he returned home and married. He next went to Elis with his wife, and heard Pyrrho, whose tenets he adopted. He also lived on the Hellespont, and taught at Chalcedon, before moving to Athens, where he lived until his death. His writings were said to have been very numerous. He composed poetry, tragedies, satiric dramas, and comedies, of which very little remains. His most famous composition was his Silloi, a satirical account of famous philosophers, living and dead; a spoudaiogeloion in hexameter verse. The Silloi has not survived intact, but it is mentioned and quoted by several ancient authors.

Example Input: Question: Which drivers finished ahead of Fabio Leimer in the 2011 Asia series? 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: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.
 Passage 3:In the United States it is the State Tree of Maine (as of 1945) and Michigan (as of 1955). Its "pine cone and tassel" is also the State Flower of Maine. Sprigs of eastern white pine were worn as badges as a symbol of Vermont identity during the Vermont Republic and are depicted in a stained glass window in the Vermont State House, on the Flag of Vermont, and on the naval ensign of the Commonwealth of Massachusetts and the state of Maine. The 1901 Maine Flag prominently featured the tree during its brief tenure as Maine's state flag. The Maine State Guard also use the tree in their uniform badges.
