In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

Example Input: Question: What was the name of father of the man who blew up part of the railroad? Passage:E11 was on her second tour when, on 6 August it successfully torpedoed the Turkish torpedo cruiser , causing serious damage. Two days later 8 August 1915 as a new British landing was underway at Suvla, E11 torpedoed the antiquated Turkish pre-dreadnought battleship off Bulair at the northern entrance to the Dardanelles. The ship sank with the loss of 21 officers and 237 men. Barbaros Hayreddin was one of two Ottoman battleships sunk during the campaign. Visiting Constantinople again, E11 sank a Black Sea collier Isfahan as it was preparing to unload — a significant blow as coal was the main fuel source and supplies were scarce. Moving into the Gulf of Izmir, on the night of 20 August, E11's first officer, Lieutenant Guy D'Oyly-Hughes, swam ashore and blew up a section of the Constantinople–Baghdad railway line, a feat for which he was awarded the Distinguished Service Cross (United Kingdom). Navigating Officer Lieutenant Robert Brown was also awarded the Distinguished Service Cross (United Kingdom). A reservist from the Merchant Navy, Brown had famously been born rounding the Cape Horn on the clipper John Gambles, the sister ship to the more famous Cutty Sark.

Example Input: Question: What main language was spoken by the tribe of which Khalid was a member? Passage:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828–832, briefly in 841 and again under Caliph al-Wathiq (r. 842–845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.

Example Input: Question: Was Lincolnshire overpopulated the year Piccaver was born? Passage:Piccaver was born on 5 February 1884 in the Lincolnshire town of Long Sutton to chemist Frederick Herman Piccaver (born 1864, died 17 February 1916) and his wife Sarah Ann Sissons. The Piccavers had been farm laborers, but there were also claims of Spanish ancestry dating back to the Spanish Armada. At a young age, Alfred emigrated with his family to the United States of America. The family resettled in Albany, NY and took American citizenship. Frederick Piccaver worked as head brewer of the Beverwyck Brewery. Alfred joined the choir of Albany's St. Peter's Episcopal Church as a boy soprano. He also became a soloist at the North Reformed Church in Watervliet. The young Piccaver went on to study voice with S. Graham Nobbes, who had been chief instructor of the Emma Willard Conservatory of Music and with Allan Lindsay, conductor of the Troy Conservatory of Music. Alfred later trained to be electrical engineer but he had a talent for singing and in 1905 he enrolled at the Metropolitan School of Opera. The school's director Heinrich Conried recognised his considerable vocal ability and in 1907 sent the young Alfred to Prague, where he studied with Ludmilla Prochazka-Neumann (1872–1954).
