Article: Sapwood (or alburnum) is the younger, outermost wood; in the growing tree it is living wood, and its principal functions are to conduct water from the roots to the leaves and to store up and give back according to the season the reserves prepared in the leaves. However, by the time they become competent to conduct water, all xylem tracheids and vessels have lost their cytoplasm and the cells are therefore functionally dead. All wood in a tree is first formed as sapwood. The more leaves a tree bears and the more vigorous its growth, the larger the volume of sapwood required. Hence trees making rapid growth in the open have thicker sapwood for their size than trees of the same species growing in dense forests. Sometimes trees (of species that do form heartwood) grown in the open may become of considerable size, 30 cm or more in diameter, before any heartwood begins to form, for example, in second-growth hickory, or open-grown pines.

Question: What essential liquid is the sapwood tasked with carrying around a tree?
Ans: water

Article: The first newspaper in Namibia was the German-language Windhoeker Anzeiger, founded 1898. Radio was introduced in 1969, TV in 1981. During German rule, the newspapers mainly reflected the living reality and the view of the white German-speaking minority. The black majority was ignored or depicted as a threat. During South African rule, the white bias continued, with mentionable influence of the Pretoria government on the "South West African" media system. Independent newspapers were seen as a menace to the existing order, critical journalists threatened.

Question: What was the language in which the first Namibian newspaper was printed in?

Article: In 1636 George, Duke of Brunswick-Luneburg, ruler of the Brunswick-Luneburg principality of Calenberg, moved his residence to Hanover. The Dukes of Brunswick-Luneburg were elevated by the Holy Roman Emperor to the rank of Prince-Elector in 1692, and this elevation was confirmed by the Imperial Diet in 1708. Thus the principality was upgraded to the Electorate of Brunswick-Luneburg, colloquially known as the Electorate of Hanover after Calenberg's capital (see also: House of Hanover). Its electors would later become monarchs of Great Britain (and from 1801, of the United Kingdom of Great Britain and Ireland). The first of these was George I Louis, who acceded to the British throne in 1714. The last British monarch who ruled in Hanover was William IV. Semi-Salic law, which required succession by the male line if possible, forbade the accession of Queen Victoria in Hanover. As a male-line descendant of George I, Queen Victoria was herself a member of the House of Hanover. Her descendants, however, bore her husband's titular name of Saxe-Coburg-Gotha. Three kings of Great Britain, or the United Kingdom, were concurrently also Electoral Princes of Hanover.

Question: Where did the Duke of Brunswick-Luneburg move his residence to?
Ans: Hanover

Article: One wave of the population boom ended abruptly in the mid-1980s, as oil prices fell precipitously. The space industry also suffered in 1986 after the Space Shuttle Challenger disintegrated shortly after launch. There was a cutback in some activities for a period. In the late 1980s, the city's economy suffered from the nationwide recession. After the early 1990s recession, Houston made efforts to diversify its economy by focusing on aerospace and health care/biotechnology, and reduced its dependence on the petroleum industry. Since the increase of oil prices in the 2000s, the petroleum industry has again increased its share of the local economy.

Question: When did Houston begin to regain its dependence on the oil industry?
Ans:
2000s
