Question: The Aleutian Islands are still home to the Aleut people's seafaring society, although they were the first Native Alaskans to be exploited by Russians. Western and Southwestern Alaska are home to the Yup'ik, while their cousins the Alutiiq ~ Sugpiaq lived in what is now Southcentral Alaska. The Gwich'in people of the northern Interior region are Athabaskan and primarily known today for their dependence on the caribou within the much-contested Arctic National Wildlife Refuge. The North Slope and Little Diomede Island are occupied by the widespread Inupiat people.
Is there an answer to this question: Which indigenous group is controversially unknown for hunting caribou on protected land?

Answer: unanswerable

Question: At the beginning of World War I, East Prussia became a theatre of war when the Russian Empire invaded the country. The Russian Army encountered at first little resistance because the bulk of the German Army had been directed towards the Western Front according to the Schlieffen Plan. Despite early success and the capture of the towns of Rastenburg and Gumbinnen, in the Battle of Tannenberg in 1914 and the Second Battle of the Masurian Lakes in 1915, the Russians were decisively defeated and forced to retreat. The Russians were followed by the German Army advancing into Russian territory.
Is there an answer to this question: In what year was the First Battle of the Masurian Lakes?

Answer: unanswerable

Question: The Arabian oryx, a species of large antelope, once inhabited much of the desert areas of the Middle East. However, the species' striking appearance made it (along with the closely related scimitar-horned oryx and addax) a popular quarry for sport hunters, especially foreign executives of oil companies working in the region.[citation needed] The use of automobiles and high-powered rifles destroyed their only advantage: speed, and they became extinct in the wild exclusively due to sport hunting in 1972. The scimitar-horned oryx followed suit, while the addax became critically endangered. However, the Arabian oryx has now made a comeback and been upgraded from "extinct in the wild" to "vulnerable" due to conservation efforts like captive breeding
Is there an answer to this question: What destroyed the Arabian oryx only advantage of speed.

Answer: automobiles and high-powered rifles

Question: In a switching circuit, the idea is to simulate, as near as possible, the ideal switch having the properties of open circuit when off, short circuit when on, and an instantaneous transition between the two states. Parameters are chosen such that the "off" output is limited to leakage currents too small to affect connected circuitry; the resistance of the transistor in the "on" state is too small to affect circuitry; and the transition between the two states is fast enough not to have a detrimental effect.
Is there an answer to this question: What is a switching circuit trying to simulate when on?

Answer:
short circuit
