Question: Hayek's principal investigations in economics concerned capital, money, and the business cycle. Mises had earlier applied the concept of marginal utility to the value of money in his Theory of Money and Credit (1912), in which he also proposed an explanation for "industrial fluctuations" based on the ideas of the old British Currency School and of Swedish economist Knut Wicksell. Hayek used this body of work as a starting point for his own interpretation of the business cycle, elaborating what later became known as the "Austrian Theory of the Business Cycle". Hayek spelled out the Austrian approach in more detail in his book, published in 1929, an English translation of which appeared in 1933 as Monetary Theory and the Trade Cycle. There he argued for a monetary approach to the origins of the cycle. In his Prices and Production (1931), Hayek argued that the business cycle resulted from the central bank's inflationary credit expansion and its transmission over time, leading to a capital misallocation caused by the artificially low interest rates. Hayek claimed that "the past instability of the market economy is the consequence of the exclusion of the most important regulator of the market mechanism, money, from itself being regulated by the market process".
Is there an answer to this question: What is the name of Mises' 1912 book?

Question: State schools are generally seen as equivalent in quality of education to private-sector institutions. However, the value of a state high-school diploma is limited by the fact that the grades obtained account for only around 25% of the final grade for each topic, with the remaining 75% assigned by the teacher during the semester, in a minimally transparent way. Cypriot universities (like universities in Greece) ignore high school grades almost entirely for admissions purposes. While a high-school diploma is mandatory for university attendance, admissions are decided almost exclusively on the basis of scores at centrally administered university entrance examinations that all university candidates are required to take.
Is there an answer to this question: What is required for university attendance?

Answer: high-school diploma


Question: In May and June 1939, the King and Queen toured Canada and the United States. From Ottawa, the royal couple were accompanied throughout by Canadian Prime Minister William Lyon Mackenzie King, to present themselves in North America as King and Queen of Canada. George was the first reigning monarch of Canada to visit North America, although he had been to Canada previously as Prince Albert and as Duke of York. Both Governor General of Canada Lord Tweedsmuir and Mackenzie King hoped that the King's presence in Canada would demonstrate the principles of the Statute of Westminster 1931, which gave full sovereignty to the British Dominions. On 19 May, George VI personally accepted and approved the Letter of Credence of the new U.S. Ambassador to Canada, Daniel Calhoun Roper; gave Royal Assent to nine parliamentary bills; and ratified two international treaties with the Great Seal of Canada. The official royal tour historian, Gustave Lanctot, wrote "the Statute of Westminster had assumed full reality" and George gave a speech emphasising "the free and equal association of the nations of the Commonwealth".
Is there an answer to this question: Who was the prime minister of Canada in 1939?

Answer: William Lyon Mackenzie King


Question: One may claim that the judiciary has historically been the weakest of the three branches. In fact, its power to exercise judicial review—its sole meaningful check on the other two branches—is not explicitly granted by the U.S Constitution. The U.S. Supreme Court exercised its power to strike down congressional acts as unconstitutional only twice prior to the Civil War: in Marbury v. Madison (1803) and Dred Scott v. Sandford (1857). The Supreme Court has since then made more extensive use of judicial review.
Is there an answer to this question: Before the Civil War, the Marbury had exercised its power to strike down what type of acts only twice?

Answer:
unanswerable
