Question: The Chinese intervention in late October 1950 bolstered the Korean People's Air Force (KPAF) of North Korea with the MiG-15, one of the world's most advanced jet fighters. The fast, heavily armed MiG outflew first-generation UN jets such as the F-80 (United States Air Force) and Gloster Meteors (Royal Australian Air Force), posing a real threat to B-29 Superfortress bombers even under fighter escort. Fearful of confronting the United States directly, the Soviet Union denied involvement of their personnel in anything other than an advisory role, but air combat quickly resulted in Soviet pilots dropping their code signals and speaking over the wireless in Russian. This known direct Soviet participation was a casus belli that the UN Command deliberately overlooked, lest the war for the Korean peninsula expand to include the Soviet Union, and potentially escalate into atomic warfare.
Try to answer this question if possible: What may have occurred if the war was expanded to the Soviet Union?
Answer: atomic warfare
Question: The administration continues to follow the market reform plans of the previous one and indicated that it will diversify Iran's oil-reliant economy. Iran has also developed a biotechnology, nanotechnology, and pharmaceuticals industry. However, nationalized industries such as the bonyads have often been managed badly, making them ineffective and uncompetitive with years. Currently, the government is trying to privatize these industries, and, despite successes, there are still several problems to be overcome, such as the lagging corruption in the public sector and lack of competitiveness. In 2010, Iran was ranked 69, out of 139 nations, in the Global Competitiveness Report.
Try to answer this question if possible: What Iranian nationalized industry has been noncompetitive and managed badly? 
Answer: the bonyads
Question: Gaddafi remained a controversial and divisive figure on the world stage throughout his life and after death. Supporters praised Gaddafi's administration for the creation of an almost classless society through domestic reform. They stress the regime's achievements in combating homelessness and ensuring access to food and safe drinking water. Highlighting that under Gaddafi, all Libyans enjoyed free education to a university level, they point to the dramatic rise in literacy rates after the 1969 revolution. Supporters have also applauded achievements in medical care, praising the universal free healthcare provided under the Gaddafist administration, with diseases like cholera and typhoid being contained and life expectancy raised. Biographers Blundy and Lycett believed that under the first decade of Gaddafi's leadership, life for most Libyans "undoubtedly changed for the better" as material conditions and wealth drastically improved, while Libyan studies specialist Lillian Craig Harris remarked that in the early years of his administration, Libya's "national wealth and international influence soared, and its national standard of living has risen dramatically." Such high standards declined during the 1980s, as a result of economic stagnation. Gaddafi claimed that his Jamahiriya was a "concrete utopia", and that he had been appointed by "popular assent", with some Islamic supporters believing that he exhibited barakah. His opposition to Western governments earned him the respect of many in the Euro-American far right.
Try to answer this question if possible: What was the cost of primary and secondary education under Gaddafi?
Answer: free
Question: Although the PC market declined, Apple still managed to ship 2.8 million MacBooks in Q2 2012 (the majority of which are the MacBook Air) compared to 500,000 total Ultrabooks, although there were dozens of Ultrabooks from various manufacturers on the market while Apple only offered 11-inch and 13-inch models of the MacBook Air. The Air has been the best-selling ultra-portable in certain countries over Windows Ultrabooks, particularly the United States. While several Ultrabooks were able to claim individual distinctions such as being the lightest or thinnest, the Air was regarded by reviewers as the best all-around subnotebook/ultraportable in regard to "OS X experience, full keyboard, superior trackpad, Thunderbolt connector and the higher-quality, all-aluminum unibody construction". The Air was among the first to receive Intel's latest CPUs before other PC manufacturers, and OS X has gained market share on Windows in recent years. Through July 1, 2013, the MacBook Air took in 56 percent of all Ultrabook sales in the United States, although being one of the higher-priced competitors, though several Ultrabooks with better features were often more expensive than the MacBook Air. The competitive pricing of MacBooks was particularly effective when rivals charged more for seemingly equivalent Ultrabooks, as this contradicted the established "elitist aura" perception that Apple products cost more but were higher quality, which made these most expensive Ultrabooks seem exorbitant no matter how valid their higher prices were.
Try to answer this question if possible: When was the competetive pricing of MacBooks especially ineffective?
Answer:
unanswerable
