Various theories for the decline of the Native American populations emphasize epidemic diseases, conflicts with Europeans, and conflicts among warring tribes. Scholars now believe that, among the various contributing factors, epidemic disease was the overwhelming cause of the population decline of the American natives. Some believe that after first contacts with Europeans and Africans, Old World diseases caused the death of 90 to 95% of the native population of the New World in the following 150 years. Smallpox killed up to one third of the native population of Hispaniola in 1518. By killing the Incan ruler Huayna Capac, smallpox caused the Inca Civil War. Smallpox was only the first epidemic. Typhus (probably) in 1546, influenza and smallpox together in 1558, smallpox again in 1589, diphtheria in 1614, measles in 1618all ravaged the remains of Inca culture.
How did smallpox cause the Inca Civil War?
****
The answer: By killing the Incan ruler Huayna Capac

There were two main techniques in Greco-Roman mosaic: opus vermiculatum used tiny tesserae, typically cubes of 4 millimeters or less, and was produced in workshops in relatively small panels which were transported to the site glued to some temporary support. The tiny tesserae allowed very fine detail, and an approach to the illusionism of painting. Often small panels called emblemata were inserted into walls or as the highlights of larger floor-mosaics in coarser work. The normal technique was opus tessellatum, using larger tesserae, which was laid on site. There was a distinct native Italian style using black on a white background, which was no doubt cheaper than fully coloured work.
What were small panel mosaics known as?
****
The answer: emblemata

The inevitable march to civil war and the combat in Madrid resulted in the removal of the capital of the Republic to Valencia. On 6 November 1936 the city became the capital of Republican Spain under the control of the prime minister Manuel Azana; the government moved to the Palau de Benicarlo, its ministries occupying various other buildings. The city was heavily bombarded by air and sea, necessitating the construction of over two hundred bomb shelters to protect the population. On 13 January 1937 the city was first shelled by a vessel of the Fascist Italian Navy, which was blockading the port by the order of Benito Mussolini. The bombardment intensified and inflicted massive destruction on several occasions; by the end of the war the city had survived 442 bombardments, leaving 2,831 dead and 847 wounded, although it is estimated that the death toll was higher, as the data given are those recognised by Francisco Franco's government. The Republican government passed to Juan Negrin on 17 May 1937 and on 31 October of that year moved to Barcelona. On 30 March 1939 Valencia surrendered and the Nationalist troops entered the city. The postwar years were a time of hardship for Valencians. During Franco's regime speaking or teaching Valencian was prohibited; in a significant reversal it is now compulsory for every schoolchild in Valencia.
Where did the government relocate to in 1937?
****
The answer: Barcelona

Agriculture accounted for less than 20% of both net material product and total employment before the dissolution of the Soviet Union in 1991. After independence, the importance of agriculture in the economy increased markedly, its share at the end of the 1990s rising to more than 30% of GDP and more than 40% of total employment. This increase in the importance of agriculture was attributable to food security needs of the population in the face of uncertainty during the first phases of transition and the collapse of the non-agricultural sectors of the economy in the early 1990s. As the economic situation stabilized and growth resumed, the share of agriculture in GDP dropped to slightly over 20% (2006 data), although the share of agriculture in employment remained more than 40%.
Was agriculture more important before or after Armenia left the Soviet Union?
****
The answer:
After
