Question: Providing 25% of Namibia's revenue, mining is the single most important contributor to the economy. Namibia is the fourth largest exporter of non-fuel minerals in Africa and the world's fourth largest producer of uranium. There has been significant investment in uranium mining and Namibia is set to become the largest exporter of uranium by 2015. Rich alluvial diamond deposits make Namibia a primary source for gem-quality diamonds. While Namibia is known predominantly for its gem diamond and uranium deposits, a number of other minerals are extracted industrially such as lead, tungsten, gold, tin, fluorspar, manganese, marble, copper and zinc. There are offshore gas deposits in the Atlantic Ocean that are planned to be extracted in the future. According to "The Diamond Investigation", a book about the global diamond market, from 1978, De Beers, the largest diamond company, bought most of the Namibian diamonds, and would continue to do so, because "whatever government eventually comes to power they will need this revenue to survive".
Is there an answer to this question: How much revenue does mining provide Namibia?

Answer: 25%

Question: The word "police" was borrowed from French into the English language in the 18th century, but for a long time it applied only to French and continental European police forces. The word, and the concept of police itself, were "disliked as a symbol of foreign oppression" (according to Britannica 1911). Before the 19th century, the first use of the word "police" recorded in government documents in the United Kingdom was the appointment of Commissioners of Police for Scotland in 1714 and the creation of the Marine Police in 1798.
Is there an answer to this question: When did the French language adopt the word 'police'?

Answer: in the 18th century

Question: The population grew rapidly, from 800,000 in 1814 to 914,000 in 1830 and 1,067,000 in 1846. The combination of economic and demographic factors led to hunger, housing shortages and a lack of work for young people. Thus, it is not surprising that people left Alsace, not only for Paris where the Alsatian community grew in numbers, with famous members such as Baron Haussmann but also for more distant places like Russia and the Austrian Empire, to take advantage of the new opportunities offered there: Austria had conquered lands in Eastern Europe from the Ottoman Empire and offered generous terms to colonists as a way of consolidating its hold on the new territories. Many Alsatians also began to sail to the United States, settling in many areas from 1820 to 1850. In 1843 and 1844, sailing ships bringing immigrant families from Alsace arrived at the port of New York. Some settled in Illinois, many to farm or to seek success in commercial ventures: for example, the sailing ships Sully (in May 1843) and Iowa (in June 1844) brought families who set up homes in northern Illinois and northern Indiana. Some Alsatian immigrants were noted for their roles in 19th-century American economic development. Others ventured to Canada to settle in southwestern Ontario, notably Waterloo County.
Is there an answer to this question: Between what years did Alatians begin to sail towards the United States?

Answer: 1820 to 1850
