Eratosthenes (276-194 BC) was a Greek mathematician and astronomer who made an amazingly close calculation of the actual circumference of the earth.  He did it by noting the angle of shadows in two cities during the summer solstice, and then doing geometric calculations that factored in the distance between the cities.  

Oh, and besides math and astronomy, Eratosthenes was also a poet and music theorist, as well as pretty much inventing the field of study we call geography today.  He was what we would call a "polymath" (a person of knowledge of all sorts of things) -- or, what the Greeks called a <span>Πένταθλος (pentathlos).</span>

How are officers in the executive branch selected in Oklahoma?
viva [34]

In order to be elected governor, any gubernatorial candidate is required to obtain a statewide plurality of votes cast in their election. Given the dominance of the two-party system in Oklahoma (between the Democrats and the Republicans), the plurality is often a majority as well. However, in case the event that two or more candidates have an equal number of votes, the state legislature, by joint ballot, elects one of those candidates governor.

The constitution names the governor the state's chief magistrate and vested in him the supreme executive power. As a consequence, the governor is the preeminent figure in Oklahoma politics. Though he or she shares power with many other executive officers, in the event of a vacancy anywhere in the executive branch, he or she appoints their successor. The governor appoints the heads of state departments and agencies as well as the members of most state commissioners and boards. However, these appointments do require Senate approval. Some serve at his or her pleasure while others serve fixed terms.

Which steps did the Hoover administration take to fight the early challenges of the Great Depression?
liq [111]

Answer:

The correct answers are C, <em>calling for immediate federal funding to support financial institutions troubled by bank runs</em> and D, <em>creating a series of federal programs to provide employment on public works</em>.

Explanation:

Republican President Herbert Hoover (1874-1964) firmly believed the government should not intervene in the economic field. Because of this his administration only actively fought the economical crisis in early 1932, when unemployment was around 23%.

During that year Hoover's administration got Congress to approve the creation of the Reconstruction Finance Corporation (RFC), an institution to financially support states' governments and financial institutions. RFC saved a few banks but not enough to ease the crisis.

In mid-1932 Hoover signed the Emergency Relief and Construction Act that liberated public funds for public works to provide employment.

Options A, B and E are wrong:

When the government worked on the housing field for low-income individuals it was not through tax cuts; (A)

it did not urge private agencies to organize relief efforts, only to not cut wages during the beginning of the crisis; (B)

on the contrary, Hoover established a moratorium on foreign debts related to World War I (1914-1918) to stop the European crisis caused by the American crisis aiming to help both economies. (E)
