Problem: The principle of the modern computer was first described by mathematician and pioneering computer scientist Alan Turing, who set out the idea in his seminal 1936 paper, On Computable Numbers. Turing reformulated Kurt Godel's 1931 results on the limits of proof and computation, replacing Godel's universal arithmetic-based formal language with the formal and simple hypothetical devices that became known as Turing machines. He proved that some such machine would be capable of performing any conceivable mathematical computation if it were representable as an algorithm. He went on to prove that there was no solution to the Entscheidungsproblem by first showing that the halting problem for Turing machines is undecidable: in general, it is not possible to decide algorithmically whether a given Turing machine will ever halt.
Who did Turing revise the results on the limits of proof and computation in 1931?
The answer is the following: Kurt Godel

Problem: The Muslim population of the region consisted mainly of native Iberian converts to Islam (the so-called Muwallad or Muladi) and to a lesser extent Berbers and Arabs. The Arabs were principally noblemen from Oman; and though few in numbers, they constituted the elite of the population. The Berbers were originally from the Atlas mountains and Rif mountains of North Africa and were essentially nomads. In Portugal, the Muslim population (or "Moors"), relatively small in numbers, stayed in the Algarve region, and south of the Tagus. Today, there are approximately 800 words in the Portuguese language of Arabic origin. The Muslims were expelled from Portugal 300 years earlier than in neighbouring Spain, which is reflected both in Portuguese culture and the language, which is mostly Celtiberian and Vulgar Latin.
Who did the Arabs principally consist of?
The answer is the following: noblemen from Oman

Problem: France and the UK, the largest shareholders in the Suez Canal Company, saw its nationalization as yet another hostile measure aimed at them by the Egyptian government. Nasser was aware that the canal's nationalization would instigate an international crisis and believed the prospect of military intervention by the two countries was 80 per cent likely. He believed, however, that the UK would not be able to intervene militarily for at least two months after the announcement, and dismissed Israeli action as "impossible". In early October, the UN Security Council met on the matter of the canal's nationalization and adopted a resolution recognizing Egypt's right to control the canal as long as it continued to allow passage through it for foreign ships. According to Heikal, after this agreement, "Nasser estimated that the danger of invasion had dropped to 10 per cent". Shortly thereafter, however, the UK, France, and Israel made a secret agreement to take over the Suez Canal, occupy the Suez Canal zone, and topple Nasser.
What nation did Nasser judge impossible to become militarially involved?
The answer is the following: Israel

Problem: Affirmative action in the United States tends to focus on issues such as education and employment, specifically granting special consideration to racial minorities, Native Americans, and women who have been historically excluded groups in America. Reports have shown that minorities and women have faced discrimination in schools and businesses for many years and this discrimination produced unfair advantages for whites and males in education and employment. The impetus toward affirmative action is redressing the disadvantages associated with past and present discrimination. Further impetus is a desire to ensure public institutions, such as universities, hospitals, and police forces, are more representative of the populations they serve.
Outside of employment, what is the other main issue that affirmative action focuses on?
The answer is the following:
education
