Problem: Please answer a question about the following article about Black people:
Being identified as either "black" or "white" in Australia during the 19th and early 20th centuries was critical in one's employment and social prospects. Various state-based Aboriginal Protection Boards were established which had virtually complete control over the lives of Indigenous Australians where they lived, their employment, marriage, education and included the power to separate children from their parents. Aborigines were not allowed to vote and were often confined to reserves and forced into low paid or effectively slave labour. The social position of mixed-race or "half-caste" individuals varied over time. A 1913 report by Sir Baldwin Spencer states that:

Problem: Please answer a question about the following article about John von Neumann:
along with two inequality systems expressing economic efficiency. In this model, the (transposed) probability vector p represents the prices of the goods while the probability vector q represents the "intensity" at which the production process would run. The unique solution represents the growth factor which is 1 plus the rate of growth of the economy; the rate of growth equals the interest rate. Proving the existence of a positive growth rate and proving that the growth rate equals the interest rate were remarkable achievements, even for von Neumann.
Was the economic model successful?
A: proving that the growth rate equals the interest rate were remarkable achievements, even for von Neumann

Problem: Please answer a question about the following article about Korean War:
The initial assault by North Korean KPA forces were aided by the use of Soviet T-34-85 tanks. A North Korean tank corps equipped with about 120 T-34s spearheaded the invasion. These drove against a ROK Army with few anti-tank weapons adequate to deal with the Soviet T-34s. Additional Soviet armor was added as the offensive progressed. The North Korean tanks had a good deal of early successes against South Korean infantry, elements of the 24th Infantry Division, and those United States built M24 Chaffee light tanks that they encountered. Interdiction by ground attack aircraft was the only means of slowing the advancing Korean armor. The tide turned in favour of the United Nations forces in August 1950 when the North Koreans suffered major tank losses during a series of battles in which the UN forces brought heavier equipment to bear, including M4A3 Sherman medium tanks backed by U.S. M26 heavy tanks, along with the British Centurion, Churchill, and Cromwell tanks.
What weapon did the the KPA use that was successful early in the Korean conflict?
A:
Soviet T-34-85 tanks
