Article: Some Estonians, unwilling to side directly with the Nazis, joined the Finnish Army (which was allied with the Nazis) to fight against the Soviet Union. The Finnish Infantry Regiment 200 (Estonian: soomepoisid) was formed out of Estonian volunteers in Finland. Although many Estonians were recruited into the German armed forces (including Estonian Waffen-SS), the majority of them did so only in 1944 when the threat of a new invasion of Estonia by the Red Army had become imminent. In January 1944 Estonia was again facing the prospect of invasion from the Red Army and the last legitimate prime minister of the Republic of Estonia (according to the Constitution of the Republic of Estonia) delivered a radio address asking all able-bodied men born from 1904 through 1923 to report for military service. The call resulted in around 38,000 new enlistments and several thousand Estonians who had joined the Finnish Army came back to join the newly formed Territorial Defense Force, assigned to defend Estonia against the Soviet advance. It was hoped[by whom?] that by engaging in such a war Estonia would be able to attract Western support for Estonian independence.

Question: Who did some Estonians join as an alternative to the Germans?
Ans: the Finnish Army


Article: Numerous modern mandolin makers build instruments that largely replicate the Gibson F-5 Artist models built in the early 1920s under the supervision of Gibson acoustician Lloyd Loar. Original Loar-signed instruments are sought after and extremely valuable. Other makers from the Loar period and earlier include Lyon and Healy, Vega and Larson Brothers. Some notable modern American carved mandolin manufacturers include, in addition to Kay, Gibson, Weber, Monteleone and Collings. Mandolins from other countries include The Loar (China), Santa, Rosa (China), Michael Kelly (Korea), Eastman (China), Kentucky (China), Heiden (Canada), Gilchrist (Australia) and Morgan Monroe (China).

Question: Who were notable modern American mandolin manufacturers? 
Ans: Kay, Gibson, Weber, Monteleone and Collings.


Article: The deliberate or accidental hybridising of two or more species of closely related animals through captive breeding is a human activity which has been in existence for millennia and has grown in recent times for economic purposes. The number of successful interspecific mammalian hybrids is relatively small, although it has come to be known that there is a significant number of naturally occurring hybrids between forms or regional varieties of a single species.[citation needed] These may form zones of gradation known as clines. Indeed, the distinction between some hitherto distinct species can become clouded once it can be shown that they may not only breed but produce fertile offspring. Some hybrid animals exhibit greater strength and resilience than either parent. This is known as hybrid vigor. The existence of the mule (donkey sire; horse dam) being used widely as a hardy draught animal throughout ancient and modern history is testament to this. Other well known examples are the lion/tiger hybrid, the liger, which is by far the largest big cat and sometimes used in circuses; and cattle hybrids such as between European and Indian domestic cattle or between domestic cattle and American bison, which are used in the meat industry and marketed as Beefalo. There is some speculation that the donkey itself may be the result of an ancient hybridisation between two wild ass species or sub-species. Hybrid animals are normally infertile partly because their parents usually have slightly different numbers of chromosomes, resulting in unpaired chromosomes in their cells, which prevents division of sex cells and the gonads from operating correctly, particularly in males. There are exceptions to this rule, especially if the speciation process was relatively recent or incomplete as is the case with many cattle and dog species. Normally behavior traits, natural hostility, natural ranges and breeding cycle differences maintain the separateness of closely related species and prevent natural hybridisation. However, the widespread disturbances to natural animal behaviours and range caused by human activity, cities, dumping grounds with food, agriculture, fencing, roads and so on do force animals together which would not normally breed. Clear examples exist between the various sub-species of grey wolf, coyote and domestic dog in North America. As many birds and mammals imprint on their mother and immediate family from infancy, a practice used by animal hybridizers is to foster a planned parent in a hybridization program with the same species as the one with which they are planned to mate.

Question: What is the marketed name given in the meat industry when you involve a european or indian domestic cattle mixed with an American bison?
Ans: Beefalo


Article: The Earth receives 174,000 terawatts (TW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet. Most people around the world live in areas with insolation levels of 150 to 300 watts per square meter or 3.5 to 7.0 kWh/m2 per day.

Question: What are the insolation levels of most populated areas?
Ans:
150 to 300 watts per square meter or 3.5 to 7.0 kWh/m2 per day
