QUES: The highest position in Islam, caliphate, was claimed by the sultans starting since Murad I, which was established as Ottoman Caliphate. The Ottoman sultan, pâdişâh 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 Enderûn, 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 (Devşirme).
What was the purpose of the palace educational system?

ANS: eliminating the unfit potential heirs, and establishing support among the ruling elite for a successor

QUES: Another common application is the control of the throttle of an internal combustion engine in conjunction with an electronic governor. In this usage, the motor works against a return spring to move the throttle in accordance with the output of the governor. The latter monitors engine speed by counting electrical pulses from the ignition system or from a magnetic pickup and, depending on the speed, makes small adjustments to the amount of current applied to the motor. If the engine starts to slow down relative to the desired speed, the current will be increased, the motor will develop more torque, pulling against the return spring and opening the throttle. Should the engine run too fast, the governor will reduce the current being applied to the motor, causing the return spring to pull back and close the throttle.
 What kinds of adjustments would a governor never make?

ANS: unanswerable

QUES: Unarmed fox hunting on horseback with hounds is the type of hunting most closely associated with the United Kingdom; in fact, "hunting" without qualification implies fox hunting. What in other countries is called "hunting" is called "shooting" (birds) or "stalking" (deer) in Britain. Originally a form of vermin control to protect livestock, fox hunting became a popular social activity for newly wealthy upper classes in Victorian times and a traditional rural activity for riders and foot followers alike. Similar to fox hunting in many ways is the chasing of hares with hounds. Pairs of Sight hounds (or long-dogs), such as greyhounds, may be used to pursue a hare in coursing, where the greyhounds are marked as to their skill in coursing the hare (but are not intended to actually catch it), or the hare may be pursued with scent hounds such as beagles or harriers. Other sorts of foxhounds may also be used for hunting stags (deer) or mink. Deer stalking with rifles is carried out on foot without hounds, using stealth.
How is deer stalking with rifles carried out?

ANS: on foot without hounds, using stealth

QUES: With this contribution of von Neumann, the axiomatic system of the theory of sets became fully satisfactory, and the next question was whether or not it was also definitive, and not subject to improvement. A strongly negative answer arrived in September 1930 at the historic mathematical Congress of Königsberg, in which Kurt Gödel announced his first theorem of incompleteness: the usual axiomatic systems are incomplete, in the sense that they cannot prove every truth which is expressible in their language. This result was sufficiently innovative as to confound the majority of mathematicians of the time.
In 1930 who gave a strongly negative answer to Von Neuman's approach to the axiomatic system of theory of sets?

ANS:
Kurt Gödel
