[EX Q]: 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.

[EX A]: Albanian troops partook in the war against the Wahhabi movement in Arabia (1811–18) and in the conquest of the Sudan (1820–24)

[EX Q]: Question: How old was the Ottoman commander during the siege when the Russian Army achieved victory at Uzunahmet? Passage:On 4 November 1877 the Russian army achieved a victory at Uzunahmet, having inflicted heavy casualties on the Turks, which included 3,000 killed and wounded, 1,000 prisoners and 42 artillery pieces left by the panicked gunners, with a loss of only 1,200 men. Although the Turkish troops ceased resistance and were fleeing in disarray, with 4,000 of them deserting the army, a part of their infantry maintained order and retreated to the well-fortified position in Erzurum with 14 guns. The Russians, being miles away and exhausted by the battle, did not chase them and therefore missed a chance to capture Erzurum on the heels of the fleeing enemy. Having developed a plan of assault on the stronghold, the Russian army advanced under the cover of night, but had difficulties of movement control in the dark. A part of their troops from the 153th Infantry Regiment mistook their direction and captured one of the redoubts, Azizieh, all by themselves, without help from the rest of the army, but had to leave it due to the lack of support. All the three Turkish battalions stationed in the Azizieh redoubt were routed, numbering 1,600, whereas the Russians lost 400 or 600 men in this battle. After the Russians left Azizieh, the Turks made an attempt to counterattack them, but were successfully driven back. As the works of Erzurum were too strong to be taken by assault, the siege park was needed at Kars and in the following days the weather set in with a snowstorm, the Russians decided to withdraw their army and instead attack Kars, which they succeeded in capturing. Ahmed Muhtar Pasha, the Ottoman commander during the siege, requested reinforcements from Istanbul and was receiving them all through November. After epidemics broke out, he withdrew his forces to Bayburt for the remainder of the war. Muhtar Pasha was awarded the title Ghazi for his role in the defence of Erzurum, Gedikler and Yahniler. The city of Erzurum would be captured by the Russians a few months later, on 8 February 1878.
