Question: Write an article that answers the following question: How many more dollars was it to construct a ditch than a dam?
Article: Successful mining took time and capital, particularly once most of the timber around the Klondike had been cut down. A realistic mining operation required $1,500  for wood to be burned to melt the ground, along with around $1,000  to construct a dam, $1,500  for ditches and up to $600  for sluice boxes, a total of $4,600. The attraction of the Klondike to a prospector, however, was that when gold was found, it was often highly concentrated. Some of the creeks in the Klondike were fifteen times richer in gold than those in California, and richer still than those in South Africa. In just two years, for example, $230,000  worth of gold was brought up from claim 29 on the Eldorado Creek.

Question: Write an article that answers the following question: Who was Hong Kong under the protection of?
Article: During the Tang dynasty , a navy town, Tuen Mun Tsan  was established in Nantou, which lies across Deep Bay. Tuen Mun and the rest of Hong Kong were under its protection. A major clan, To , brought the name Tuen Mun to the area.  They migrated from Jiangxi on the Chinese mainland and established a village Tuen Mun Tsuen  late in the Yuan dynasty .  As more and more villages were established, the village was renamed Tuen Mun Tai Tsuen , which means "large village" in Chinese.  As yet more villages were established, a market town of Tuen Mun Hui   was established. This town lies where present-day Tuen Mun Kau Hui is situated. Tuen Mun remained an important town of coastal defence until the start of British rule in 1898. When the British took over the New Territories from the Qing government in this year, the area was renamed Castle Peak, and Tuen Mun Hui to Castle Peak Market  or Tsing Shan Hui. The name Tuen Mun, however, continued to be used by those living in the area. In 1965, "Castle Peak New Town" was planned. It was later renamed Tuen Mun New Town and constructed from 1970 onwards with many buildings on the reclamed land of the former Castle Peak Bay. The name was officially changed back to Tuen Mun in 1972. The first public housing estate built in the town was Castle Peak Estate, opened 1971.

Question: Write an article that answers the following question: How many financial crises had the Czech Republic faced since 1990?
Article: Growth continued in the first years of the EU membership. The credit portion of the Financial crisis of 2007-2010 did not affect the Czech Republic much, mostly due to its stable banking sector which has learned its lessons during a smaller crisis in the late 1990s and became much more cautious. As a fraction of the GDP, the Czech public debt is among the smallest ones in Central and Eastern Europe. Moreover, unlike many other post-communist countries, an overwhelming majority of the household debt - over 99% - is denominated in the local Czech currency. That's why the country wasn't affected by the shrunken money supply in the U.S. dollars. However, as a large exporter, the economy was sensitive to the decrease of the demand in Germany and other trading partners. In the middle of 2009, the annual drop of the GDP for 2009 was estimated around 3% or 4.3%, a relatively modest decrease. The impact of the economic crisis may have been limited by the existence of the national currency that temporarily weakened in H1 of 2009, simplifying the life of the exporters.

Question: Write an article that answers the following question: How many years did Theodor Philipsen live for?
Article: Painting has continued to be a prominent form of artistic expression in Danish culture, inspired by and also influencing major international trends in this area. These include impressionism and the modernist styles of expressionism, abstract painting and surrealism. While international co-operation and activity has almost always been essential to the Danish artistic community, influential art collectives with a firm Danish base includes De Tretten (1909–1912), Linien (1930s and 1940s), COBRA (avant-garde movement) (1948–51), Fluxus (1960s and 1970s), Junge Wilde (1980s) and more recently Superflex (founded in 1993). Most Danish painters of modern times have also been very active with other forms of artistic expressions, such as sculpting, ceramics, art installations, activism, film and experimental architecture. Notable Danish painters from modern times representing various art movements include Theodor Philipsen (1840–1920, impressionism and naturalism), Anna Klindt Sørensen (1899–1985, expressionism), Franciska Clausen (1899–1986, Neue Sachlichkeit, cubism, surrealism and others), Henry Heerup (1907–1993, naivism), Robert Jacobsen (1912–1993, abstract painting), Carl Henning Pedersen (1913–2007, abstract painting), Asger Jorn (1914–1973, Situationist, abstract painting), Bjørn Wiinblad (1918–2006, art deco, orientalism), Per Kirkeby (b. 1938, neo-expressionism, abstract painting), Per Arnoldi (b. 1941, pop art), Michael Kvium (b. 1955, neo-surrealism) and Simone Aaberg Kærn (b. 1969, superrealism).
