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.

Question: 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.

Question: Question: How high is the gamma radiation from nuclear fuel? Passage:The nuclear fuel elements were made of refractory ceramic based on beryllium oxide, with enriched uranium dioxide as fuel and small amount of zirconium dioxide for structural stability. The fuel elements were hollow hexagonal tubes about long with distance between the outer parallel planes, with inside diameter of . They were manufactured by high-pressure extruding of the green compact, then sintering almost to its theoretical density. The core consisted of 465,000 individual elements stacked to form 27,000 airflow channels; the design with small unattached elements reduced problems related with thermal stresses. The elements were designed for average operation temperature of ; the autoignition temperature of the reactor base plates was only 150 °C higher. The neutron flux was calculated to be 9×10 neutrons/(cm·s) in the aft and 7×10 neutrons/(cm·s) in the nose. The gamma radiation level was fairly high due to the lack of shielding; radiation hardening for the guidance electronics had to be designed.

Question: Question: What team won the tournament that the third-choice keeper played in? Passage:After of the departure of Pinto to Mexican club Atlas, the club's corporation Azul Azul, informed that Conde will be the first keeper for the 2011 season, despite of the arrival of Nery Veloso and also of Carlos Alfaro, who would be the back–up keepers of Conde. However, on 24 January, Jhonny Herrera returned to the club after five years, playing at Audax Italiano the last season, in where achieved the recognition of be Chilean Primera División's best keeper of the season. Despite of Herrera's return, the things for Esteban were somewhat favorable, because Unión San Felipe signed to Nery Veloso and the third–choice keeper Carlos Alfaro made a poor South American Youth Championship at Peru under the coach César Vaccia. That left to the charrua as the second–choice keeper for the season. His first game in the season was recently on 30 June for the first week of the Torneo de Clausura, playing in a 3–0 home win over Deportes La Serena, failing to play in the Torneo de Apertura, because Jorge Sampaoli, not considered him during the season.
