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: After the World Cup, the most important international football competitions are the continental championships, which are organised by each continental confederation and contested between national teams. These are the European Championship (UEFA), the Copa America (CONMEBOL), African Cup of Nations (CAF), the Asian Cup (AFC), the CONCACAF Gold Cup (CONCACAF) and the OFC Nations Cup (OFC). The FIFA Confederations Cup is contested by the winners of all six continental championships, the current FIFA World Cup champions and the country which is hosting the Confederations Cup. This is generally regarded as a warm-up tournament for the upcoming FIFA World Cup and does not carry the same prestige as the World Cup itself. The most prestigious competitions in club football are the respective continental championships, which are generally contested between national champions, for example the UEFA Champions League in Europe and the Copa Libertadores in South America. The winners of each continental competition contest the FIFA Club World Cup.

A: What does UEFA Stand against?

Q: Passage: Other pre-modern Chinese names for Tibet include Wusiguo (Chinese: ; pinyin: Wusiguo; cf. Tibetan dbus, U, [wy]), Wusizang (Chinese: ; pinyin: wusizang, cf. Tibetan dbus-gtsang, U-Tsang), Tubote (Chinese: ; pinyin: Tubote), and Tanggute (Chinese: ; pinyin: Tanggute, cf. Tangut). American Tibetologist Elliot Sperling has argued in favor of a recent tendency by some authors writing in Chinese to revive the term Tubote (simplified Chinese: ; traditional Chinese: ; pinyin: Tubote) for modern use in place of Xizang, on the grounds that Tubote more clearly includes the entire Tibetan plateau rather than simply the Tibet Autonomous Region.[citation needed]

A:
Who was Sperling Elliot?
