Problem: I know that the answer to the question "How were successors chosen?" is in "The highest position in Islam, caliphate, was claimed by the sultans starting since Murad I, which was established as Ottoman Caliphate. The Ottoman sultan, padisah or "lord of kings", served as the Empire's sole regent and was considered to be the embodiment of its government, though he did not always exercise complete control. The Imperial Harem was one of the most important powers of the Ottoman court. It was ruled by the Valide Sultan. On occasion, the Valide Sultan would become involved in state politics. For a time, the women of the Harem effectively controlled the state in what was termed the "Sultanate of Women". New sultans were always chosen from the sons of the previous sultan. The strong educational system of the palace school was geared towards eliminating the unfit potential heirs, and establishing support among the ruling elite for a successor. The palace schools, which would also educate the future administrators of the state, were not a single track. First, the Madrasa (Ottoman Turkish: Medrese) was designated for the Muslims, and educated scholars and state officials according to Islamic tradition. The financial burden of the Medrese was supported by vakifs, allowing children of poor families to move to higher social levels and income. The second track was a free boarding school for the Christians, the Enderun, which recruited 3,000 students annually from Christian boys between eight and twenty years old from one in forty families among the communities settled in Rumelia or the Balkans, a process known as Devshirme (Devsirme).".

Problem: I know that the answer to the question "Which species never became fully extinct in the wild?" is in "The Arabian oryx, a species of large antelope, once inhabited much of the desert areas of the Middle East. However, the species' striking appearance made it (along with the closely related scimitar-horned oryx and addax) a popular quarry for sport hunters, especially foreign executives of oil companies working in the region.[citation needed] The use of automobiles and high-powered rifles destroyed their only advantage: speed, and they became extinct in the wild exclusively due to sport hunting in 1972. The scimitar-horned oryx followed suit, while the addax became critically endangered. However, the Arabian oryx has now made a comeback and been upgraded from "extinct in the wild" to "vulnerable" due to conservation efforts like captive breeding". Can you tell me what it is?

A: addax

Problem: I know that the answer to the question "The bushi took over the?" is in "A struggle for succession in the mid-twelfth century gave the Fujiwara an opportunity to regain their former power. Fujiwara no Yorinaga sided with the retired emperor in a violent battle in 1156 against the heir apparent, who was supported by the Taira and Minamoto (Hogen Rebellion). In the end, the Fujiwara were destroyed, the old system of government supplanted, and the insei system left powerless as bushi took control of court affairs, marking a turning point in Japanese history. In 1159, the Taira and Minamoto clashed (Heiji Rebellion), and a twenty-year period of Taira ascendancy began.". Can you tell me what it is?

Problem: I know that the answer to the question "what group was mentioned third?" is in "Nasser was known for his intimate relationship with ordinary Egyptians. His availability to the public, despite assassination attempts against him, was unparalleled among his successors. A skilled orator, Nasser gave 1,359 speeches between 1953 and 1970, a record for any Egyptian head of state. Historian Elie Podeh wrote that a constant theme of Nasser's image was "his ability to represent Egyptian authenticity, in triumph or defeat". The national press also helped to foster his popularity and profilemore so after the nationalization of state media. Historian Tarek Osman wrote:". Can you tell me what it is?
