Article: 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.

Question: How do the Chinese refer to Tibetan people, language, and culture?
Ans: Zang

Article: The cultural role of copper has been important, particularly in currency. Romans in the 6th through 3rd centuries BC used copper lumps as money. At first, the copper itself was valued, but gradually the shape and look of the copper became more important. Julius Caesar had his own coins made from brass, while Octavianus Augustus Caesar's coins were made from Cu-Pb-Sn alloys. With an estimated annual output of around 15,000 t, Roman copper mining and smelting activities reached a scale unsurpassed until the time of the Industrial Revolution; the provinces most intensely mined were those of Hispania, Cyprus and in Central Europe.

Question: What became more important than the copper value for Roman coins?
Ans: the shape and look

Article: Heartwood (or duramen) is wood that as a result of a naturally occurring chemical transformation has become more resistant to decay. Heartwood formation occurs spontaneously (it is a genetically programmed process). Once heartwood formation is complete, the heartwood is dead. Some uncertainty still exists as to whether heartwood is truly dead, as it can still chemically react to decay organisms, but only once.

Question: How does heartwood formation occur due to its being genetically programmed?
Ans:
spontaneously
