PROBLEM: Passage: The spotted green pigeon or Liverpool pigeon (Caloenas maculata) is a species of pigeon which is most likely extinct. It was first mentioned and described in 1783 by John Latham, who had seen two specimens of unknown provenance and a drawing depicting the bird. The taxonomic relationships of the bird were long obscure, and early writers suggested many different possibilities, though the idea that it was related to the Nicobar pigeon (C. nicobarica) prevailed, and it was therefore placed in the same genus, Caloenas. Today, the species is only known from a specimen kept in World Museum, Liverpool. Overlooked for much of the 20th century, it was recognised as a valid extinct species by the IUCN Red List only in 2008. In 2014 a genetic study confirmed it as a distinct species related to the Nicobar pigeon, and showed that the two were the closest relatives of the extinct dodo and Rodrigues solitaire.
Link Information: The animal order Columbiformes is also constituted of pigeons and doves, and includes about 42 genera and 310 species.
Question: How many species of pigeons are there?

SOLUTION: Answer: 310

PROBLEM: Passage: The reign of Farouk was characterized by ever increasing nationalist discontent over the British occupation, royal corruption and incompetence, and the disastrous 1948 ArabIsraeli 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 (181118) and in the conquest of the Sudan (182024). 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.
