The modern Standard Chinese exonym for the ethnic Tibetan region is Zangqu (Chinese: ; pinyin: Zangqu), which derives by metonymy from the Tsang region around Shigatse plus the addition of a Chinese suffix, qu, which means "area, district, region, ward". Tibetan people, language, and culture, regardless of where they are from, are referred to as Zang (Chinese: ; pinyin: Zang) although the geographical term Xizang is often limited to the Tibet Autonomous Region. The term Xizang was coined during the Qing dynasty in the reign of the Jiaqing Emperor (17961820) through the addition of a prefix meaning "west" ( xi) to Zang.

Alaska (i/lsk/) is a U.S. state situated in the northwest extremity of the Americas. The Canadian administrative divisions of British Columbia and Yukon border the state to the east while Russia has a maritime border with the state to the west across the Bering Strait. To the north are the Chukchi and Beaufort Seas, the southern parts of the Arctic Ocean. To the south and southwest is the Pacific Ocean. Alaska is the largest state in the United States by area, the 3rd least populous and the least densely populated of the 50 United States. Approximately half of Alaska's residents (the total estimated at 738,432 by the Census Bureau in 2015) live within the Anchorage metropolitan area. Alaska's economy is dominated by the fishing, natural gas, and oil industries, resources which it has in abundance. Military bases and tourism are also a significant part of the economy.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many of Alaska's residents reside in the Anchorage area?
Ah, so.. Approximately half

The evolutionary relationships and heredity of a group of organisms is called its phylogeny. Phylogenetic studies attempt to discover phylogenies. The basic approach is to use similarities based on shared inheritance to determine relationships. As an example, species of Pereskia are trees or bushes with prominent leaves. They do not obviously resemble a typical leafless cactus such as an Echinocactus. However, both Pereskia and Echinocactus have spines produced from areoles (highly specialised pad-like structures) suggesting that the two genera are indeed related.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How are the relationships within the group determined?
Ah, so..
