Problem: New York City:

New York City has the largest European and non-Hispanic white population of any American city. At 2.7 million in 2012, New York's non-Hispanic white population is larger than the non-Hispanic white populations of Los Angeles (1.1 million), Chicago (865,000), and Houston (550,000) combined. The European diaspora residing in the city is very diverse. According to 2012 Census estimates, there were roughly 560,000 Italian Americans, 385,000 Irish Americans, 253,000 German Americans, 223,000 Russian Americans, 201,000 Polish Americans, and 137,000 English Americans. Additionally, Greek and French Americans numbered 65,000 each, with those of Hungarian descent estimated at 60,000 people. Ukrainian and Scottish Americans numbered 55,000 and 35,000, respectively. People identifying ancestry from Spain numbered 30,838 total in 2010. People of Norwegian and Swedish descent both stood at about 20,000 each, while people of Czech, Lithuanian, Portuguese, Scotch-Irish, and Welsh descent all numbered between 12,000–14,000 people. Arab Americans number over 160,000 in New York City, with the highest concentration in Brooklyn. Central Asians, primarily Uzbek Americans, are a rapidly growing segment of the city's non-Hispanic white population, enumerating over 30,000, and including over half of all Central Asian immigrants to the United States, most settling in Queens or Brooklyn. Albanian Americans are most highly concentrated in the Bronx.

Problem: The rural Plains have lost a third of their population since 1920. Several hundred thousand square miles (several hundred thousand square kilometers) of the Great Plains have fewer than 6 inhabitants per square mile (2.3 inhabitants per square kilometer)—the density standard Frederick Jackson Turner used to declare the American frontier "closed" in 1893. Many have fewer than 2 inhabitants per square mile (0.77 inhabitants per square kilometer). There are more than 6,000 ghost towns in the state of Kansas alone, according to Kansas historian Daniel Fitzgerald. This problem is often exacerbated by the consolidation of farms and the difficulty of attracting modern industry to the region. In addition, the smaller school-age population has forced the consolidation of school districts and the closure of high schools in some communities. The continuing population loss has led some to suggest that the current use of the drier parts of the Great Plains is not sustainable, and there has been a proposal - the "Buffalo Commons" - to return approximately 139,000 square miles (360,000 km2) of these drier parts to native prairie land.

Context and question: Old English was first written in runes, using the futhorc – a rune set derived from the Germanic 24-character elder futhark, extended by five more runes used to represent Anglo-Saxon vowel sounds, and sometimes by several more additional characters. From around the 9th century, the runic system came to be supplanted by a (minuscule) half-uncial script of the Latin alphabet introduced by Irish Christian missionaries. This was replaced by insular script, a cursive and pointed version of the half-uncial script. This was used until the end of the 12th century when continental Carolingian minuscule (also known as Caroline) replaced the insular.
How many Anglo-Saxon vowels were there?
Answer: unanswerable


Question: In its long history, Valencia has acquired many local traditions and festivals, among them the Falles, which were declared Celebrations of International Touristic Interest (Fiestas de Interés Turístico Internacional) on 25 January 1965, and the Water Tribunal of Valencia (Tribunal de las Aguas de Valencia), which was declared an intangible cultural heritage of humanity (Patrimonio Cultural Inmaterial de la Humanidad) in 2009. In addition to these Valencia has hosted world-class events that helped shape the city's reputation and put it in the international spotlight, e.g., the Regional Exhibition of 1909, the 32nd and the 33rd America's Cup competitions, the European Grand Prix of Formula One auto racing, the Valencia Open 500 tennis tournament, and the Global Champions Tour of equestrian sports.

Question: According to Der Spiegel, credits given to European governments were disguised as "swaps" and consequently did not get registered as debt because Eurostat at the time ignored statistics involving financial derivatives. A German derivatives dealer had commented to Der Spiegel that "The Maastricht rules can be circumvented quite legally through swaps," and "In previous years, Italy used a similar trick to mask its true debt with the help of a different US bank." These conditions had enabled Greek as well as many other European governments to spend beyond their means, while meeting the deficit targets of the European Union and the monetary union guidelines. In May 2010, the Greek government deficit was again revised and estimated to be 13.6% which was the second highest in the world relative to GDP with Iceland in first place at 15.7% and Great Britain third with 12.6%. Public debt was forecast, according to some estimates, to hit 120% of GDP during 2010.
Is there an answer to this question: What was again revised in May of 2010?

Answer:
Greek government deficit
