Q: Passage: Of Alaska's 2010 Census population figure of 710,231, 20,429 people, or 2.88% of the population, did not live in an incorporated city or census-designated place. Approximately three-quarters of that figure were people who live in urban and suburban neighborhoods on the outskirts of the city limits of Ketchikan, Kodiak, Palmer and Wasilla. CDPs have not been established for these areas by the United States Census Bureau, except that seven CDPs were established for the Ketchikan-area neighborhoods in the 1980 Census (Clover Pass, Herring Cove, Ketchikan East, Mountain Point, North Tongass Highway, Pennock Island and Saxman East), but have not been used since. The remaining population was scattered throughout Alaska, both within organized boroughs and in the Unorganized Borough, in largely remote areas.

A: In 2010, what percent of Alaska's population did not live in a city or CPD?

Q: Passage: Armenian literature dates back to 400 AD, when Mesrop Mashtots first invented the Armenian alphabet. This period of time is often viewed as the Golden Age of Armenian literature. Early Armenian literature was written by the "father of Armenian history", Moses of Chorene, who authored The History of Armenia. The book covers the time-frame from the formation of the Armenian people to the fifth century AD. The nineteenth century beheld a great literary movement that was to give rise to modern Armenian literature. This period of time, during which Armenian culture flourished, is known as the Revival period (Zartonki sherchan). The Revivalist authors of Constantinople and Tiflis, almost identical to the Romanticists of Europe, were interested in encouraging Armenian nationalism. Most of them adopted the newly created Eastern or Western variants of the Armenian language depending on the targeted audience, and preferred them over classical Armenian (grabar). This period ended after the Hamidian massacres, when Armenians experienced turbulent times. As Armenian history of the 1920s and of the Genocide came to be more openly discussed, writers like Paruyr Sevak, Gevork Emin, Silva Kaputikyan and Hovhannes Shiraz began a new era of literature.

A:
When did Gevork Emin invent the Armenian alphabet?
