Dust Bowl

The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s; severe drought and a failure to apply dryland farming methods to prevent  the aeolian processes (wind erosion) caused the phenomenon.[1][2] The drought came in three waves, 1934, 1936, and 1939–1940, but some regions of the high plains experienced drought conditions for as many as eight years.[3] With insufficient understanding of the ecology of the plains, farmers had conducted extensive deep plowing of the virgin topsoil of the Great Plains during the previous decade; this had displaced the native, deep-rooted grasses that normally trapped soil and moisture even during periods of drought and high winds.  The rapid mechanization of farm equipment, especially small gasoline tractors, and widespread use of the combine harvester contributed to farmers' decisions to convert arid grassland (much of which received no more than 10inches (~250mm) of precipitation per year) to cultivated cropland.[4]

Question: What caused the Dust Bowl?
Answer: severe drought and a failure to apply dryland farming methods to prevent  the aeolian processes (wind erosion)

Rough Riders

The Rough Riders was a nickname given to the 1st United States Volunteer Cavalry, one of three such regiments raised in 1898 for the Spanish–American War and the only one to see action. The United States Army was small and understaffed in comparison to its status during the American Civil War roughly thirty years prior. As a measure towards rectifying this situation President William McKinley called upon 125,000 volunteers to assist in the war efforts.[1] The regiment was also called "Wood's Weary Walkers" in honor of its first commander, Colonel Leonard Wood. This nickname served to acknowledge that despite being a cavalry unit they ended up fighting on foot as infantry.

History of Portuguese

The Portuguese language developed in the Western Iberian Peninsula from Latin spoken by Roman soldiers and colonists starting in the 3rd century BC. Old Portuguese, also known as Galician-Portuguese, began to diverge from other Romance languages after the fall of the Western Roman Empire and the Germanic invasions, also known as barbarian invasions in the 5th century and started appearing in written documents around the 9th century. By the 13th century, Galician-Portuguese had become a mature language with its own literature and began to split into two languages. However, the debate of whether Galician and Portuguese are nowadays varieties of the same language, much like American English or British English, is still present. In all aspects—phonology, morphology, lexicon and syntax—Portuguese is essentially the result of an organic evolution of Vulgar Latin with some influences from other languages, namely the native Gallaecian and Lusitanian languages spoken prior to the Roman domination.

Question: When did the Portuguese language develop?
Answer: 3rd century BC

Lux

The lux (symbol: lx) is the SI derived unit of illuminance and luminous emittance, measuring luminous flux per unit area.[1] It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watt per square metre, but with the power at each wavelength weighted according to the luminosity function, a standardized model of human visual brightness perception. In English, "lux" is used as both the singular and plural form.[2]

Question: What is the unit of measurement for light brightness?
Answer: lux

Fibromyalgia

The cause of fibromyalgia is unknown; however, it is believed to involve a combination of genetic and environmental factors, with each playing a substantial role.[4][5] The condition runs in families and many genes are believed to be involved.[8] Environmental factors may include psychological stress, trauma and certain infections.[4] The pain appears to result from processes in the central nervous system and the condition is referred to as a "central sensitization syndrome".[3][4] Fibromyalgia is recognized as a disorder by the US National Institutes of Health and the American College of Rheumatology.[5][9] There is no specific diagnostic test.[5] Diagnosis involves first ruling out other potential causes and verifying that a set number of symptoms are present.[4][5]

Question: How is Fibromyalgia caused?
Answer: unknown
Julius Caesar Chappelle

Julius Caesar Chappelle was born into slavery in 1852 at Chappelle's Landing, a plantation near Edgefield, Newberry County, South Carolina, to an enslaved mother. He was classified as a "mulatto," visibly of mixed race, with African-European ancestry.[5] Among his siblings were brothers Lewis and Mitchell. This upland area was developed for cotton cultivation in antebellum era after the invention of the cotton gin made short-staple cotton profitable. Edgefield also was known for its potteries. South Carolina has been documented as having some of the worst conditions for slaves during the time period of slavery in America, and its population was majority black from before the American Revolution into the early 20th century.  During slavery, it was often common for plantation owners to break up families and move them to different plantations of the same owner in order to stop possible uprisings.  There is evidence that during very early childhood Julius C. Chappelle and at least one of his brothers may have been moved from South Carolina to two other plantations in different states before being brought back to the South Carolina plantations in Newberry County, South Carolina.[6]

Question: On what plantation was Julius Caesar Chappelle a slave?
Answer: Chappelle's Landing

List of cloud types

The list of cloud types groups the tropospheric types as high (cirrus, cirrocumulus, cirrostratus), middle (altocumulus, altostratus), multi-level (nimbostratus, cumulus, cumulonimbus), and low (stratocumulus, stratus) according to the altitude level or levels at which each cloud is normally found. Small cumulus are commonly grouped with the low clouds because they do not show significant vertical extent. Of the multi-level genus-types, those with the greatest convective activity are often grouped separately as towering vertical.  The genus types all have Latin names.

Question: What are the types of clouds?
Answer: high (cirrus, cirrocumulus, cirrostratus), middle (altocumulus, altostratus), multi-level (nimbostratus, cumulus, cumulonimbus), and low (stratocumulus, stratus)
History of the Venezuelan oil industry

Despite the knowledge of the existence of oil reserves in Venezuela for centuries, the first oil wells of significance were not drilled until the early 1910s. In 1908, Juan Vicente Gómez replaced his ailing predecessor, Cipriano Castro, as the president of Venezuela.  Over the next few years, Gómez granted several concessions to explore, produce, and refine oil.  Most of these oil concessions were granted to his closest friends, and they in turn passed them on to foreign oil companies that could actually develop them.[8]  One such concession was granted to Rafael Max Valladares who hired Caribbean Petroleum Company (later acquired by Royal Dutch Shell) to carry out his oil exploration project. On 15 April 1914, upon the completion of the Zumaque-I (now called MG-I) oil well, the first Venezuelan oilfield of importance, Mene Grande, was discovered by Caribbean Petroleum in the Maracaibo Basin.[7]  This major discovery encouraged a massive wave of foreign oil companies to Venezuela in an attempt to get a piece of the action.

Question: What was the first company to drill for oil in Venezuela?
Answer: Caribbean Petroleum Company
History of Nickelodeon

Nickelodeon's history dates back to December 1, 1977, when QUBE,[1] the first two-way major market interactive cable television system was launched in Columbus, Ohio by Warner Cable Corp. One of the ten "community" channels that were offered at no additional charge to QUBE subscribers was C-3, which exclusively carried Pinwheel each day from 7:00a.m. to 9:00p.m. Eastern Time.[2] Nickelodeon was developed by Dr. Vivian Horner, who worked as director of research on the PBS series The Electric Company and who had created Pinwheel for QUBE (one of Nickelodeon's earliest series, which spun off from the C-3 service), along with Warner Cable CEO Gus Hauser. Nickelodeon was originally used as a loss leader for then-parent company Warner Cable.[3] As the company saw it, having a commercial-free children's channel would prove useful in franchising its cable systems across the country, with that advantage putting them over rival companies such as HBO.

Question: When did Nickelodeon network start?
Answer: December 1, 1977
Montana Vigilantes
