Problem: United States dollar:

Dollar coins have not been very popular in the United States. Silver dollars were minted intermittently from 1794 through 1935; a copper-nickel dollar of the same large size, featuring President Dwight D. Eisenhower, was minted from 1971 through 1978. Gold dollars were also minted in the 19th century. The Susan B. Anthony dollar coin was introduced in 1979; these proved to be unpopular because they were often mistaken for quarters, due to their nearly equal size, their milled edge, and their similar color. Minting of these dollars for circulation was suspended in 1980 (collectors' pieces were struck in 1981), but, as with all past U.S. coins, they remain legal tender. As the number of Anthony dollars held by the Federal Reserve and dispensed primarily to make change in postal and transit vending machines had been virtually exhausted, additional Anthony dollars were struck in 1999. In 2000, a new $1 coin, featuring Sacagawea, (the Sacagawea dollar) was introduced, which corrected some of the problems of the Anthony dollar by having a smooth edge and a gold color, without requiring changes to vending machines that accept the Anthony dollar. However, this new coin has failed to achieve the popularity of the still-existing $1 bill and is rarely used in daily transactions. The failure to simultaneously withdraw the dollar bill and weak publicity efforts have been cited by coin proponents as primary reasons for the failure of the dollar coin to gain popular support.

Problem: Following the catastrophic events in Asia Minor, the monarchy was abolished via a referendum in 1924 and the Second Hellenic Republic was declared. Premier Georgios Kondylis took power in 1935 and effectively abolished the republic by bringing back the monarchy via a referendum in 1935. A coup d'etat followed in 1936 and installed Ioannis Metaxas as the head of a dictatorial regime known as the 4th of August Regime. Although a dictatorship, Greece remained on good terms with Britain and was not allied with the Axis.
The Greek monarchy was reestablished by who?

Canada allows nonprofits to be incorporated or unincorporated. Nonprofits may incorporate either federally, under Part II of the Canada Business Corporations Act or under provincial legislation. Many of the governing Acts for Canadian nonprofits date to the early 1900s, meaning that nonprofit legislation has not kept pace with legislation that governs for-profit corporations; particularly with regards to corporate governance. Federal, and in some provinces (such as Ontario), incorporation is by way of Letters Patent, and any change to the Letters Patent (even a simple name change) requires formal approval by the appropriate government, as do by-law changes. Other provinces (such as Alberta) permit incorporation as of right, by the filing of Articles of Incorporation or Articles of Association.
How is incorporation handled in Ontario?
A: Letters Patent

Question: The geographical regions in which Iranian languages were spoken were pushed back in several areas by newly neighbouring languages. Arabic spread into some parts of Western Iran (Khuzestan), and Turkic languages spread through much of Central Asia, displacing various Iranian languages such as Sogdian and Bactrian in parts of what is today Turkmenistan, Uzbekistan and Tajikistan. In Eastern Europe, mostly comprising the territory of modern-day Ukraine, southern European Russia, and parts of the Balkans, the core region of the native Scythians, Sarmatians, and Alans had been decisively been taken over as a result of absorption and assimilation (e.g. Slavicisation) by the various Proto-Slavic population of the region, by the 6th century AD. This resulted in the displacement and extinction of the once predominant Scythian languages of the region. Sogdian's close relative Yaghnobi barely survives in a small area of the Zarafshan valley east of Samarkand, and Saka as Ossetic in the Caucasus, which is the sole remnant of the once predominant Scythian languages in Eastern Europe proper and large parts of the North Caucasus. Various small Iranian languages in the Pamirs survive that are derived from Eastern Iranian.
Is there an answer to this question: What language writing to some parts of eastern Iran?

Answer: unanswerable
