In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: How old was Ibrahim Pasha the year the conquest of the Sudan began? Passage:The reign of Farouk was characterized by ever increasing nationalist discontent over the British occupation, royal corruption and incompetence, and the disastrous 1948 Arab–Israeli War. All these factors served to terminally undermine Farouk's position and paved the way for the revolution of 1952. Farouk was forced to abdicate in favor of his infant son Ahmed-Fuad who became King Fuad II, while administration of the country passed to the Free Officers Movement under Muhammad Naguib and Gamal Abdel Nasser. The infant king's reign lasted less than a year and on June 18, 1953, the revolutionaries abolished the monarchy and declared Egypt a republic, ending a century and a half of the Muhammad Ali Dynasty's rule. Emerging victorious from a war-triangle (Ottomans, Mamluks, and his loyal troops), Mehmed Ali made good use of Albanian irregulars services as mercenaries and troops to bolster his reign. Albanian mercenaries, or Arnauts, presented the backbone of Ali's army and were known as elite and undisciplined soldiers of the Ottoman Empire armies. With the rise of Muhammad Ali in power, many of them would settle in Egypt and serve there. By 1815, the number of Albanian military was over 7000. Albanian troops partook in the war against the Wahhabi movement in Arabia (1811–18) and in the conquest of the Sudan (1820–24). The number of Albanian troops would diminish in 1823, when Ibrahim Pasha, Ali's son, would join the Ottoman armies in the Greek War of Independence along with circa 17,000 men, many of them Albanians. Ali's dynasty would continue to rule Egypt until 1952.

Example Input: Question: What attributes did the goddess whose birthday was being observed commonly have associated with her? Passage:The Panathenaea (, "all-Athenian festival") was the most important festival for Athens and one of the grandest in the entire ancient Greek world. Except for slaves, all inhabitants of the polis could take part in the festival. This holiday of great antiquity is believed to have been the observance of Athena's birthday and honoured the goddess as the city's patron divinity, Athena Polias ('Athena of the city'). A procession assembled before dawn at the Dipylon gate in the northern sector of the city. The procession, led by the Kanephoros, made its way to the Areopagus and in front of the Temple of Athena Nike next to the Propylaea. Only Athenian citizens were allowed to pass through the Propylaea and enter the Acropolis. The procession passed the Parthenon and stopped at the great altar of Athena in front of the Erechtheum. Every four years a newly woven peplos was dedicated to Athena.

Example Input: Question: What other indigenous Australians lived in the Goo-een area? Passage:Archaeological evidence suggests Indigenous Australians inhabited the area for more than ten thousand years before European settlement. The Indigenous tribe that lived in the area were known as the Kombumerri people and spoke the Yugambeh language. The Kombumerri people named the area Goo-een. In 1869, Richard Gardiner became the first European to settle in the area, which was known as Nerang Creek Heads at the time. Gardiner built a house and wharf on the river end of Queen Street which later led to the Loder family and several others following his lead and building in the area. The settlement was surveyed in 1874 and the area was renamed Southport because it was the southernmost port of the colony of Queensland and took inspiration from the English seaside town. In 1877 German immigrant Johan Meyer acquired James Beattie's land at Narrow Neck and started a private ferry service that transported Southport residents to the beachside area that was named Elston shortly after. Meyer's Ferry operated just south of Queen Street on Meyer's Ferry Road and would take travelers across the Nerang River to Elston's Meyer's Ferry Road. In 1878 Richard Gardner opened the Southport Hotel, the town's first pub.
