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 is the closest nation to Lord Howe Island? Passage 1:The "three now cosmopolitan commensal rodent pest species" (the brown rat, the black rat and the house mouse) have been dispersed in association with humans, partly on sailing ships in the Age of Exploration, and with a fourth species in the Pacific, the Polynesian rat (Rattus exulans), have severely damaged island biotas around the world. For example, when the black rat reached Lord Howe Island in 1918, over 40 percent of the terrestrial bird species of the island, including the Lord Howe fantail, became extinct within ten years. Similar destruction has been seen on Midway Island (1943) and Big South Cape Island (1962). Conservation projects can with careful planning completely eradicate these pest rodents from islands using an anticoagulant rodenticide such as brodifacoum. This approach has been successful on the island of Lundy in the United Kingdom, where the eradication of an estimated 40,000 brown rats is giving populations of Manx shearwater and Atlantic puffin a chance to recover from near-extinction.
 Passage 2:He began his studies in Poland and continued his education at the University of Leuven. His considerable wealth enabled him to establish his own private army, which suppressed Cossack riots and Tatar raids in Ukraine. In 1635 he became the first voivode of the Czernihów Voivodship. In 1646 he was appointed Field Crown Hetman. During the Khmelnytsky Uprising, he was captured by the Tatars after the Battle of Korsun in 1648. He was a prisoner-of-war until 1650 when he was ransomed. On 12 May 1651 he commanded victorious Polish army in the Battle of Kopyczyńce between Poles and combined Cossack-Tatar forces under chief Asand Demko. In 1651, during the subsequent hostilities between the Commonwealth and Cossack-Tatar alliance, he was the nominal commander of the Polish army right wing at the great victorious Battle of Beresteczko (de facto commanded Jeremi Wiśniowiecki). Upon death of Grand Crown Hetman Mikołaj Potocki, who was his political and personal adversary, hetman Kalinowski commanded the choicest elements of the Commonwealth army and he had at the camp at Batoh about 10–12,000 soldiers and 10–15,000 servants and camp followers. This army was surprised by the combined Cossack-Tatar army, consequently defeated and then capture of Polish soldiers and servants resulted in a wholesale slaughter of the best elements of Commonwealth army and their retinues, the event known as Battle of Batoh. Hetman was killed on 2 June 1652, during the last day of the battle, when trying to escape from the Cossack-Tatars-filled burning Polish camp, in woods some 3 kilometers from the Polish camp. Hetman's severed head was carried around the Cossack-Tatar camps, allegedly by the Nuredin-Sultan himself.
 Passage 3:In the late 1950s, Dunstan became well known for his campaign against the death penalty being imposed on Max Stuart, who was convicted of rape and murder of a small girl. He harried Premier Thomas Playford IV aggressively over the matter, creating an uproar over what he saw as an unfair process. Playford eventually relented, and appeared shaken thereafter; the event was seen as a turning point in the Liberal and Country League's decline, and Labor gained momentum. During Labor's time in opposition, Dunstan was prominent in securing some reforms in Aboriginal rights, and was at the forefront of Labor abandoning the White Australia Policy. Labor conducted an extensive campaign in marginal LCL seats at the 1965 election, resulting in 21 of 39 seats, with Frank Walsh and the Labor Party taking power and Dunstan becoming Attorney-General. The LCL opposition changed leaders and installed the young Steele Hall, worrying Labor as the elderly Walsh appeared bumbling in contrast. This resulted in Labor replacing Walsh with Dunstan. Despite maintaining a much larger vote over the LCL, Labor lost two seats at the 1968 election, with the LCL forming government with support of an independent. Dunstan responded by increasing his attacks on the Playmander and was able to convincingly sustain Playmander attacks with the effect of convincing the LCL into watering down the malapportionment. Again with little change in Labor's vote but with the Playmander removed, Labor won 27 of 47 seats at the 1970 election. With a fairer seat and boundary system in place, Dunstan won three more elections, in 1973, 1975 and 1977.
