Juscelino Kubitschek, President of Brazil from 1956 to 1961, ordered the construction of Brasilia, fulfilling the promise of the Constitution and his own political campaign promise. Building Brasilia was part of Juscelino's "fifty years of prosperity in five" plan. Lucio Costa won a contest and was the main urban planner in 1957, with 5550 people competing. Oscar Niemeyer, a close friend, was the chief architect of most public buildings and Roberto Burle Marx was the landscape designer. Brasilia was built in 41 months, from 1956 to April 21, 1960, when it was officially inaugurated.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): During what time period was Lucio Costa President of Brazil?
Ah, so.. unanswerable

From early Christian times, hunting has been forbidden to Roman Catholic Church clerics. Thus the Corpus Juris Canonici (C. ii, X, De cleric. venat.) says, "We forbid to all servants of God hunting and expeditions through the woods with hounds; and we also forbid them to keep hawks or falcons." The Fourth Council of the Lateran, held under Pope Innocent III, decreed (canon xv): "We interdict hunting or hawking to all clerics." The decree of the Council of Trent is worded more mildly: "Let clerics abstain from illicit hunting and hawking" (Sess. XXIV, De reform., c. xii), which seems to imply that not all hunting is illicit, and canonists generally make a distinction declaring noisy (clamorosa) hunting unlawful, but not quiet (quieta) hunting.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What kind of hunting was legal under the Corpus Juris Canonici?
Ah, so.. unanswerable

There have been modern studies that have supported the original autopsy finding. In a 2008 study, researchers analysed samples of Napoleon's hair from throughout his life, as well as samples from his family and other contemporaries. All samples had high levels of arsenic, approximately 100 times higher than the current average. According to these researchers, Napoleon's body was already heavily contaminated with arsenic as a boy, and the high arsenic concentration in his hair was not caused by intentional poisoning; people were constantly exposed to arsenic from glues and dyes throughout their lives.[note 7] Studies published in 2007 and 2008 dismissed evidence of arsenic poisoning, and confirmed evidence of peptic ulcer and gastric cancer as the cause of death.
