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: What type of ship was Eclipse? Passage 1:The 118th Infantry Regiment traces its lineage to the year 1846, when the 1st South Carolina Volunteer Infantry was organized for duty in the Mexican–American War. Company E, "Johnson's Rifles", lives on today as 4–118. During the American Civil War, the 1st South Carolina Volunteer Infantry was reorganized into units of the First Corps, Army of Northern Virginia, under General James Longstreet in 1861. The battalions of the South Carolina regiment first saw action at the First Battle of Bull Run, where the Union Army was defeated. They next fought in the Peninsula Campaign, and eventually had to retreat from General George B. McClellan's forces at the Battle of Williamsburg in mid-1862. Shortly after, the South Carolinians fought again at the Battle of Seven Pines, where the Union advance on Richmond, Virginia was stopped even though the Confederate forces did not deliver a decisive defeat. Longstreet's Corps recovered from the losses of the Peninsula Campaign and defeated the Union at the Battle of Gaines's Mill 26 days later, and followed the victory by decisively defeating the Union Army in the Second Battle of Bull Run. The battalions of the original 1st South Carolina took part on the Battle of Antietam on 17 September 1862, the bloodiest single-day battle in American history, with a combined tally of 22,717 dead, wounded, or missing.
 Passage 2:Robert Elwes travelled extensively in his twenties and thirties, but in 1848 he embarked on a journey that was to take him round the world. Robert Elwes, aged 28, left England on 20 March 1848 on board the Eclipse. This voyage around the world took two years and three months, sailing on 10 different ships. He painted and sketched many scenes on his journey. He arrived in Rio de Janeiro, Brazil, having crossed the Atlantic from Tenerife in 30 days. He explored a little of Brazil and then sailed to Buenos Aires, Argentina. He crossed the Pampas on horseback, a journey of 1,000 miles, crossing the Andes by mule and up the Pacific coast to Lima. He sailed across the Pacific to Honolulu and Tahiti and was shipwrecked off Tasmania in September 1849. Rescued by sealers and taken to Hobart with a cargo of 500 sheep, he then travelled overland across Tasmania to Launceston where he sailed (nervously) for Australia.
 Passage 3:Despite an emergency appendectomy that delayed his spring training and shortened his time to get in shape for the season, Hershiser had been named NL Baseball Pitcher of the Month in April and a participant in the 1988 All-Star Game, getting outs against all three batters. In the eight games he started between July 10 and August 14, Hershiser had a 3–4 win–loss record with a 4.76 earned run average (ERA), raising his season ERA from 2.46 to 3.06. Following his August 14 start in which he left the game after two innings (his shortest appearance since 1985) with the Dodgers behind the Giants 8–2, he pitched complete games on August 19 (a shutout) and August 24. Prior to the game, Hershiser trailed teammate Tim Leary in shutouts, six to three, and Leary also combined with other pitchers to record a shutout that was not counted in his individual total.

Example Input: Question: How large was the area Pleistarchus was put in command of? Passage 1:Pleistarchus or Plistarch (; lived 4th century BC) was son of Antipater and brother of Cassander, king of Macedonia. He is first mentioned in the year 313 BC, when he was left by his brother in the command of Chalcis, to make headway against Ptolemy, the general of Antigonus, when Cassander himself was recalled to the defence of Macedonia. Again, in 302 BC, when the general coalition was formed against Antigonus, Pleistarchus was sent forward by his brother, with an army 12,000 foot and 500 horse, to join Lysimachus in Asia. As the Hellespont and entrance of the Euxine was occupied by Demetrius, he endeavoured to transport his troops from Odessus direct to Heraclea, but lost by far the greater part on the passage, some having been captured by the enemy's ships, while others perished in a storm, in which Pleistarchus himself narrowly escaped shipwreck. Notwithstanding this misfortune, he seems to have rendered efficient service to the confederates, for which he was rewarded after the battle of Ipsus (301 BC) by obtaining the province of Cilicia, as an independent government. This, however, he did not long retain, being expelled from it in the following year by Demetrius, almost without opposition. Afterwards he is recorded in inscriptions as the ruler of Caria; he was apparently given this province after the battle of Ipsus, and ruled there for at least seven years. Pausanias mentions him as having been defeated by the Athenians in an action in which he commanded the cavalry and auxiliaries of Cassander; but the period at which this event took place is uncertain. It is perhaps to him that the medical writer, Diocles of Carystus, addressed his work, which is cited more than once by Athenaeus, as τα προς Πλεισταρχον Υγιεινα.
 Passage 2:During World War II he was a soldier of the Szare Szeregi and the Home Army. Arrested by the Gestapo in 1943, he was imprisoned in the infamous Pawiak prison and then sent to Auschwitz concentration camp. Transferred to Sachsenhausen-Oranienburg he was liberated by American forces on 3 May 1945. In September of that year he joined the Polish II Corps and briefly served in counter-intelligence in Northern Italy. In 1947 he moved to Bodney in the United Kingdom and then settled in London. Working for various BOC branches, he devoted most of his spare time to studies on Polish aviation history, notably the history of Polish armed forces during World War II. 
 Passage 3:He joined fellow Championship side Stoke City for a £225,000 fee in August 2006. He was made captain when Michael Duberry left in January 2007 and Stoke went on to narrowly miss out on a play-off place. With Stoke not being promoted Higginbotham again decided to hand in a transfer request to help force through a move to Sunderland. He spent one season at the Stadium of Light before returning to Stoke in 2008. He became a vital member of Tony Pulis' squad as Stoke established themselves in the Premier League. He scored the winning goal in the FA Cup quarter-final against West Ham United but missed out on both the semi-final and the final due to a knee injury. After his recovery he struggled to force his way back into the side and spent time out on loan to Nottingham Forest and Ipswich Town before joining Sheffield United on a free transfer in January 2013. After eight months at Bramall Lane, he left to join Conference Premier side Chester before ending his career with a short spell at Altrincham.

Example Input: Question: During what years was the Early Bronze Age? Passage 1:Topol began his acting career during his Israeli army service in the Nahal entertainment troupe, and later toured Israel with kibbutz theatre and satirical theatre companies. He was a co-founder of the Haifa Theatre. His breakthrough film role came in 1964 as the title character in Sallah Shabati, by Israeli writer Ephraim Kishon, for which he won a Golden Globe for Most Promising Newcomer—Male. Topol went on to appear in more than 30 films in Israel and the United States, including Galileo (1975), Flash Gordon (1980) and For Your Eyes Only (1981). He was described as Israel's only internationally recognized entertainer from the 1960s through 1980s. He won a Golden Globe for Best Actor and was nominated for an Academy Award for Best Actor for his 1971 film portrayal of Tevye, and was nominated for a Tony Award for Best Actor for a 1991 Broadway revival of Fiddler on the Roof.
 Passage 2:As a result of negotiations and the 1984 agreement between China and Britain, Hong Kong was returned to China and became its first Special Administrative Region on 1 July 1997, under the principle of "one country, two systems". Hong Kong has a different political system from mainland China. Hong Kong's independent judiciary functions under the common law framework. The Hong Kong Basic Law, the constitutional document drafted by the Chinese side before the handover based on the terms enshrined in the Joint Declaration, governs its political system, and stipulates that Hong Kong shall have a high degree of autonomy in all matters except foreign relations and military defence. The declaration stipulates that the region maintain its capitalist economic system and guarantees the rights and freedoms of its people for at least 50 years after the 1997 handover. The guarantees over the territory's autonomy and the individual rights and freedoms are enshrined in the Hong Kong Basic Law, which outlines the system of governance of the Hong Kong Special Administrative Region, but which is subject to the interpretation of the Standing Committee of the National People's Congress (NPCSC).
 Passage 3:Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 7000 BC. The south-western and western part of the Iranian Plateau participated in the traditional Ancient Near East with Elam, from the Early Bronze Age, and later with various other peoples, such as the Kassites, Mannaeans, and Gutians. Georg Wilhelm Friedrich Hegel calls the Persians the "first Historical People". The Medes unified Iran as a nation and empire in 625 BC. The Achaemenid Empire (550–330 BC), founded by Cyrus the Great, was the first true global superpower state and it ruled from the Balkans to North Africa and also Central Asia, spanning three continents, from their seat of power in Persis (Persepolis). It was the largest empire yet seen and the first world empire. The Achaemenid Empire was the only civilization in all of history to connect over 40% of the global population, accounting for approximately 49.4 million of the world's 112.4 million people in around 480 BC. They were succeeded by the Seleucid, Parthian, and Sasanian Empires, who successively governed Iran for almost 1,000 years and made Iran once again as a leading power in the world. Persia's arch-rival was the Roman Empire and its successor, the Byzantine Empire.
