Question: Armenians have had a presence in the Armenian Highland for over four thousand years, since the time when Hayk, the legendary patriarch and founder of the first Armenian nation, led them to victory over Bel of Babylon. Today, with a population of 3.5 million, they not only constitute an overwhelming majority in Armenia, but also in the disputed region of Nagorno-Karabakh. Armenians in the diaspora informally refer to them as Hayastantsis (Հայաստանցի), meaning those that are from Armenia (that is, those born and raised in Armenia). They, as well as the Armenians of Iran and Russia speak the Eastern dialect of the Armenian language. The country itself is secular as a result of Soviet domination, but most of its citizens identify themselves as Apostolic Armenian Christian.
Is there an answer to this question: Who did Hayk defeat?

Answer: Bel of Babylon


Question: Chopin's disease and the cause of his death have since been a matter of discussion. His death certificate gave the cause as tuberculosis, and his physician, Jean Cruveilhier, was then the leading French authority on this disease. Other possibilities have been advanced including cystic fibrosis, cirrhosis and alpha 1-antitrypsin deficiency. However, the attribution of tuberculosis as principal cause of death has not been disproved. Permission for DNA testing, which could put the matter to rest, has been denied by the Polish government.
Is there an answer to this question: What has the Polish government not allowed to find true cause of death?

Answer: DNA testing


Question: While there is typically only one conceptual (or logical) and physical (or internal) view of the data, there can be any number of different external views. This allows users to see database information in a more business-related way rather than from a technical, processing viewpoint. For example, a financial department of a company needs the payment details of all employees as part of the company's expenses, but does not need details about employees that are the interest of the human resources department. Thus different departments need different views of the company's database.
Is there an answer to this question: Who is not allowed to see database information?

Answer: unanswerable


Question: Medieval writers divided history into periods such as the "Six Ages" or the "Four Empires", and considered their time to be the last before the end of the world. When referring to their own times, they spoke of them as being "modern". In the 1330s, the humanist and poet Petrarch referred to pre-Christian times as antiqua (or "ancient") and to the Christian period as nova (or "new"). Leonardo Bruni was the first historian to use tripartite periodisation in his History of the Florentine People (1442). Bruni and later historians argued that Italy had recovered since Petrarch's time, and therefore added a third period to Petrarch's two. The "Middle Ages" first appears in Latin in 1469 as media tempestas or "middle season". In early usage, there were many variants, including medium aevum, or "middle age", first recorded in 1604, and media saecula, or "middle ages", first recorded in 1625. The alternative term "medieval" (or occasionally "mediaeval") derives from medium aevum. Tripartite periodisation became standard after the German 17th century historian Christoph Cellarius divided history into three periods: Ancient, Medieval, and Modern.
Is there an answer to this question: Who wrote the History of the Florentine People?

Answer:
Leonardo Bruni
