Problem: Mandolin:

Mandolin has also been used in blues music, most notably by Ry Cooder, who performed outstanding covers on his very first recordings, Yank Rachell, Johnny "Man" Young, Carl Martin, and Gerry Hundt. Howard Armstrong, who is famous for blues violin, got his start with his father's mandolin and played in string bands similar to the other Tennessee string bands he came into contact with, with band makeup including "mandolins and fiddles and guitars and banjos. And once in a while they would ease a little ukulele in there and a bass fiddle." Other blues players from the era's string bands include Willie Black (Whistler And His Jug Band), Dink Brister, Jim Hill, Charles Johnson, Coley Jones (Dallas String Band), Bobby Leecan (Need More Band), Alfred Martin, Charlie McCoy (1909-1950), Al Miller, Matthew Prater, and Herb Quinn.

Problem: Popper coined the term "critical rationalism" to describe his philosophy. Concerning the method of science, the term indicates his rejection of classical empiricism, and the classical observationalist-inductivist account of science that had grown out of it. Popper argued strongly against the latter, holding that scientific theories are abstract in nature, and can be tested only indirectly, by reference to their implications. He also held that scientific theory, and human knowledge generally, is irreducibly conjectural or hypothetical, and is generated by the creative imagination to solve problems that have arisen in specific historico-cultural settings.
What did Popper think could be tested only directly?

A significant modification of Cubism between 1914 and 1916 was signaled by a shift towards a strong emphasis on large overlapping geometric planes and flat surface activity. This grouping of styles of painting and sculpture, especially significant between 1917 and 1920, was practiced by several artists; particularly those under contract with the art dealer and collector Léonce Rosenberg. The tightening of the compositions, the clarity and sense of order reflected in these works, led to its being referred to by the critic Maurice Raynal (fr) as 'crystal' Cubism. Considerations manifested by Cubists prior to the outset of World War I—such as the fourth dimension, dynamism of modern life, the occult, and Henri Bergson's concept of duration—had now been vacated, replaced by a purely formal frame of reference.
Whose concept of duration was not left behind for a for more concrete frame's of references?
A: unanswerable


Context and question: Sectional tensions had long existed between the states located north of the Mason–Dixon line and those south of it, primarily centered on the "peculiar institution" of slavery and the ability of states to overrule the decisions of the national government. During the 1840s and 1850s, conflicts between the two sides became progressively more violent. After the election of Abraham Lincoln in 1860 (who southerners thought would work to end slavery) states in the South seceded from the United States, beginning with South Carolina in late 1860. On April 12, 1861, forces of the South (known as the Confederate States of America or simply the Confederacy) opened fire on Fort Sumter, whose garrison was loyal to the Union.
What was the first state to formally secede?
Answer: South Carolina

Is there an answer to this question: What was most significant in architecture according to Ruskin?

Answer: the aesthetic

Child soldiers have and continue to play a major part in the Burmese Army as well as Burmese rebel movements. The Independent reported in June 2012 that "Children are being sold as conscripts into the Burmese military for as little as $40 and a bag of rice or a can of petrol." The UN's Special Representative of the Secretary-General for Children and Armed Conflict, Radhika Coomaraswamy, who stepped down from her position a week later, met representatives of the Government of Myanmar on 5 July 2012 and stated that she hoped the government's signing of an action plan would "signal a transformation." In September 2012, the Myanmar Armed Forces released 42 child soldiers and the International Labour Organization met with representatives of the government as well as the Kachin Independence Army to secure the release of more child soldiers. According to Samantha Power, a US delegation raised the issue of child soldiers with the government in October 2012. However, she did not comment on the government's progress towards reform in this area.
