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: When did the war begin that was ended by the Treaty of Lutatius? Passage 1:The son of Julian and Lady Caroline Faber, Faber comes from an aristocratic political family drawn from the Whig and latterly the Conservative traditions. His maternal grandfather Harold Macmillan was Prime Minister at the time of his birth. His grandmother, Lady Dorothy Cavendish, was descended from three Prime Ministers, the 4th Duke of Devonshire (1756–1757), the 2nd Earl of Shelburne (1782-1783) and the 3rd Duke of Portland (1783 and 1807–1809), related by marriage to President John F. Kennedy. Faber's great-great-great-granduncle was Lord Hartington and his great-grandfather Victor Cavendish, 9th Duke of Devonshire was also statesman. His cousin Andrew Cavendish, 11th Duke of Devonshire was married to Deborah Mitford. His uncle Maurice Macmillan was a leading figure of Edward Heath's 1970s government.
 Passage 2:All of SR 198 was added to the state highway system in the three bond issues floated to pay for the construction of the system. The first bond issue, approved by the state's voters in 1910, included the road from Visalia west to Hanford, connecting the two county seats with the central north–south highway (Route 4, now SR 99). As part of the 1916 bond issue, the route was extended west from Hanford through Coalinga to the coast trunk highway (Route 2, now US 101) near San Lucas, and assigned it the Route 10 designation. The third bond issue, passed in 1919, included a further extension east from Visalia to Sequoia National Park. The entire length of Route 10 was marked as Sign Route 198 in 1934, and this number was adopted legislatively in the 1964 renumbering. The portion east of Interstate 5 near Coalinga was added to the California Freeway and Expressway System in 1959, and parts of it have been built as such. The construction of the freeway east of Visalia to Road 192 was approved in January 1961, with the remainder of the freeway unplanned at that time as contingent on the routing of SR 65. The projected cost in 1958 of the entire freeway east of Visalia was $13 million (equivalent to $ in ) and was scheduled to be completed by 1964. The freeway through Visalia was completed by 1965, with an expressway connecting it to US 99. Also completed was the expressway heading west out of Hanford, with part of it access-controlled west of Lemoore.
 Passage 3:The Treaty of Lutatius officially ended the First Punic War. It received its name from Gaius Lutatius Catulus, the Roman consul and victor of the Battle of the Aegates Islands who negotiated it with a subordinate of Hamilcar Barca in 241 BC. According to the historian Polybius, the terms of the accord dictated that Carthage must evacuate Sicily, not make war upon Syracuse or its allies, hand over all prisoners taken during the war, and pay an indemnity of 2200 talents (66 tons) of silver in 20 annual installments. Originally rejected by the Roman people, these terms were eventually adopted with very little change under the authority of Quintus Lutatius Cerco, the brother of Gaius Lutatius Catulus. In the final agreement, Carthage was only given ten years to pay an indemnity of 3200 talents (96 tons), and had to evacuate the islands between Sicily and Italy (Ustica and the Aeolian Islands) and Aegadian Islands off western coast of Sicily.
