question:
Passage: Cultural and career issues in the U.S. Air Force have been cited as one of the reasons for the shortfall in needed UAV operators. In spite of an urgent need for UAVs or drones to provide round the clock coverage for American troops during the Iraq War, the USAF did not establish a new career field for piloting them until the last year of that war and in 2014 changed its RPA training syllabus again, in the face of large aircraft losses in training, and in response to a GAO report critical of handling of drone programs. Paul Scharre has reported that the cultural divide between the USAF and US Army has kept both services from adopting each other's drone handing innovations. Question: What is the reason for the shortage of UAV operators in the US Air Force?
answer:
Cultural and career issues


question:
Passage: 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. Question: Who feared engaging in direct conflict with the United States?
answer:
Soviet Union


question:
Passage: The publication of vernacular literature increased, with Dante (d. 1321), Petrarch (d. 1374) and Giovanni Boccaccio (d. 1375) in 14th-century Italy, Geoffrey Chaucer (d. 1400) and William Langland (d. c. 1386) in England, and François Villon (d. 1464) and Christine de Pizan (d. c. 1430) in France. Much literature remained religious in character, and although a great deal of it continued to be written in Latin, a new demand developed for saints' lives and other devotional tracts in the vernacular languages. This was fed by the growth of the Devotio Moderna movement, most prominently in the formation of the Brethren of the Common Life, but also in the works of German mystics such as Meister Eckhart and Johannes Tauler (d. 1361). Theatre also developed in the guise of miracle plays put on by the Church. At the end of the period, the development of the printing press in about 1450 led to the establishment of publishing houses throughout Europe by 1500. Question: In what language was most religious literature of this period written?
answer:

Latin
