Problem: Despite odds of four to one, the III Corps launched a risky attack. The French were routed and the III Corps captured Vionville, blocking any further escape attempts to the west. Once blocked from retreat, the French in the fortress of Metz had no choice but to engage in a fight that would see the last major cavalry engagement in Western Europe. The battle soon erupted, and III Corps was shattered by incessant cavalry charges, losing over half its soldiers. The German Official History recorded 15,780 casualties and French casualties of 13,761 men.
What odds were at stake for the attack launched by the III Corps?
The answer is the following: four to one

Problem: Southampton as a Port and city has had a long history of administrative independence of the surrounding County; as far back as the reign of King John the town and its port were removed from the writ of the King's Sheriff in Hampshire and the rights of custom and toll were granted by the King to the burgesses of Southampton over the port of Southampton and the Port of Portsmouth; this tax farm was granted for an annual fee of 200 in the charter dated at Orival on 29 June 1199. The definition of the port of Southampton was apparently broader than today and embraced all of the area between Lymington and Langstone. The corporation had resident representatives in Newport, Lymington and Portsmouth. By a charter of Henry VI, granted on 9 March 1446/7 (25+26 Hen. VI, m. 32), the mayor, bailiffs and burgesses of the towns and ports of Southampton and Portsmouth became a County incorporate and separate from Hampshire.
What was the annual fee paid by the burgesses of Southampton for the rights of custom and toll laid out in the charter of 1199?
The answer is the following: 200

Problem: In most cases, the non-penalized team will have the option of declining the penalty; in which case the results of the previous play stand as if the penalty had not been called. One notable exception to this rule is if the kicking team on a 3rd down punt play is penalized before the kick occurs: the receiving team may not decline the penalty and take over on downs. After the kick is made, change of possession occurs and subsequent penalties are assessed against either the spot where the ball is caught, or the runback.
Who can decline a penalty?
The answer is the following: the non-penalized team

Problem: One of the most spectacular examples of obligate mutualism is between the siboglinid tube worms and symbiotic bacteria that live at hydrothermal vents and cold seeps. The worm has no digestive tract and is wholly reliant on its internal symbionts for nutrition. The bacteria oxidize either hydrogen sulfide or methane, which the host supplies to them. These worms were discovered in the late 1980s at the hydrothermal vents near the Galapagos Islands and have since been found at deep-sea hydrothermal vents and cold seeps in all of the world's oceans.
When were the worms found?
The answer is the following:
the late 1980s
