Problem: United States dollar:

The United States Mint produces Proof Sets specifically for collectors and speculators. Silver Proofs tend to be the standard designs but with the dime, quarter, and half dollar containing 90% silver. Starting in 1983 and ending in 1997, the Mint also produced proof sets containing the year's commemorative coins alongside the regular coins. Another type of proof set is the Presidential Dollar Proof Set where four special $1 coins are minted each year featuring a president. Because of budget constraints and increasing stockpiles of these relatively unpopular coins, the production of new Presidential dollar coins for circulation was suspended on December 13, 2011, by U.S. Treasury Secretary Timothy F. Geithner. Future minting of such coins will be made solely for collectors.

When was the production of silver coins suspended?

Problem: New Haven was the subject of Who Governs? Democracy and Power in An American City, a very influential book in political science by preeminent Yale professor Robert A. Dahl, which includes an extensive history of the city and thorough description of its politics in the 1950s. New Haven's theocratic history is also mentioned several times by Alexis de Tocqueville in his classic volume on 19th-century American political life, Democracy in America. New Haven was the residence of conservative thinker William F. Buckley, Jr., in 1951, when he wrote his influential God and Man at Yale. William Lee Miller's The Fifteenth Ward and the Great Society (1966) similarly explores the relationship between local politics in New Haven and national political movements, focusing on Lyndon Johnson's Great Society and urban renewal.
What is the name of popular book discussing the politics of New Haven published in the 50s?

Context and question: In August 2005, Houston became a shelter to more than 150,000 people from New Orleans who evacuated from Hurricane Katrina. One month later, approximately 2.5 million Houston area residents evacuated when Hurricane Rita approached the Gulf Coast, leaving little damage to the Houston area. This was the largest urban evacuation in the history of the United States. In September 2008, Houston was hit by Hurricane Ike. As many as forty percent refused to leave Galveston Island because they feared the traffic problems that happened after Hurricane Rita.
When did Hurricane Ike hit the Houston area?

Question: Strange matter is a particular form of quark matter, usually thought of as a liquid of up, down, and strange quarks. It is contrasted with nuclear matter, which is a liquid of neutrons and protons (which themselves are built out of up and down quarks), and with non-strange quark matter, which is a quark liquid that contains only up and down quarks. At high enough density, strange matter is expected to be color superconducting. Strange matter is hypothesized to occur in the core of neutron stars, or, more speculatively, as isolated droplets that may vary in size from femtometers (strangelets) to kilometers (quark stars).
Is there an answer to this question: What is nuclear matter similar to?

Answer: unanswerable


Problem: Molotov%E2%80%93Ribbentrop Pact:

After the Baltic states were forced to accept treaties, Stalin turned his sights on Finland, confident that Finnish capitulation could be attained without great effort. The Soviets demanded territories on the Karelian Isthmus, the islands of the Gulf of Finland and a military base near the Finnish capital Helsinki, which Finland rejected. The Soviets staged the shelling of Mainila and used it as a pretext to withdraw from the non-aggression pact. The Red Army attacked in November 1939. Simultaneously, Stalin set up a puppet government in the Finnish Democratic Republic.[clarification needed] The leader of the Leningrad Military District Andrei Zhdanov commissioned a celebratory piece from Dmitri Shostakovich, entitled "Suite on Finnish Themes" to be performed as the marching bands of the Red Army would be parading through Helsinki. After Finnish defenses surprisingly held out for over three months while inflicting stiff losses on Soviet forces, the Soviets settled for an interim peace. Finland ceded southeastern areas of Karelia (10% of Finnish territory), which resulted in approximately 422,000 Karelians (12% of Finland's population) losing their homes. Soviet official casualty counts in the war exceeded 200,000, although Soviet Premier Nikita Khrushchev later claimed the casualties may have been one million.

The Soviets took over and setup a real government in what country?
