Problem: 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.
How is the the decree of the Council of Trent is worded?
The answer is the following: mildly

Problem: Hydrostatic gauges (such as the mercury column manometer) consist of a vertical column of liquid in a tube whose ends are exposed to different pressures. The column will rise or fall until its weight is in equilibrium with the pressure differential between the two ends of the tube. The simplest design is a closed-end U-shaped tube, one side of which is connected to the region of interest. Any fluid can be used, but mercury is preferred for its high density and low vapour pressure. Simple hydrostatic gauges can measure pressures ranging from 1 torr (100 Pa) to above atmospheric. An important variation is the McLeod gauge which isolates a known volume of vacuum and compresses it to multiply the height variation of the liquid column. The McLeod gauge can measure vacuums as high as 10−6 torr (0.1 mPa), which is the lowest direct measurement of pressure that is possible with current technology. Other vacuum gauges can measure lower pressures, but only indirectly by measurement of other pressure-controlled properties. These indirect measurements must be calibrated via a direct measurement, most commonly a McLeod gauge.
Why is the McLeod gauge special?
The answer is the following: can measure vacuums as high as 10−6 torr

Problem: Mexico City remains the only Latin American city to host the Olympic Games, having held the Summer Olympics in 1968, winning bids against Buenos Aires, Lyon and Detroit. (This too will change thanks to Rio, 2016 Summer Games host). The city hosted the 1955 and 1975 Pan American Games, the last after Santiago and São Paulo withdrew. The ICF Flatwater Racing World Championships were hosted here in 1974 and 1994. Lucha libre is a Mexican style of wrestling, and is one of the more popular sports throughout the country. The main venues in the city are Arena México and Arena Coliseo.
Which American city did Mexico City defeat to host the 1968 olympics?
The answer is the following: Detroit

Problem: John initially adopted a defensive posture similar to that of 1199: avoiding open battle and carefully defending his key castles. John's operations became more chaotic as the campaign progressed, and Philip began to make steady progress in the east. John became aware in July that Arthur's forces were threatening his mother, Eleanor, at Mirebeau Castle. Accompanied by William de Roches, his seneschal in Anjou, he swung his mercenary army rapidly south to protect her. His forces caught Arthur by surprise and captured the entire rebel leadership at the battle of Mirebeau. With his southern flank weakening, Philip was forced to withdraw in the east and turn south himself to contain John's army.
Why was Philip forced to withdraw in the east?
The answer is the following:
southern flank weakening
