Problem: The main exporter of rhodium is South Africa (approximately 80% in 2010) followed by Russia. The annual world production is 30 tonnes. The price of rhodium is highly variable. In 2007, rhodium cost approximately eight times more than gold, 450 times more than silver, and 27,250 times more than copper by weight. In 2008, the price briefly rose above $10,000 per ounce ($350,000 per kilogram). The economic slowdown of the 3rd quarter of 2008 pushed rhodium prices sharply back below $1,000 per ounce ($35,000 per kilogram); the price rebounded to $2,750 by early 2010 ($97,000 per kilogram) (more than twice the gold price), but in late 2013, the prices were less than $1000.

When was the price of rhodium the lowest?
Answer: 3rd quarter of 2008

Problem: In 1466, perhaps 40,000 people died of the plague in Paris. During the 16th and 17th centuries, the plague was present in Paris around 30 per cent of the time. The Black Death ravaged Europe for three years before it continued on into Russia, where the disease was present somewhere in the country 25 times between 1350 and 1490. Plague epidemics ravaged London in 1563, 1593, 1603, 1625, 1636, and 1665, reducing its population by 10 to 30% during those years. Over 10% of Amsterdams population died in 16231625, and again in 16351636, 1655, and 1664. Plague occurred in Venice 22 times between 1361 and 1528. The plague of 15761577 killed 50,000 in Venice, almost a third of the population. Late outbreaks in central Europe included the Italian Plague of 16291631, which is associated with troop movements during the Thirty Years War, and the Great Plague of Vienna in 1679. Over 60% of Norways population died in 13481350. The last plague outbreak ravaged Oslo in 1654.

How many percents did Amsterdam's population die?
Answer: 10

Problem: Hoping to rebound from their road loss to the Falcons, the Lions played their Week 2 home opener against their NFC North foe, the Green Bay Packers. In the first quarter, Detroit trailed as Packers QB Aaron Rodgers completed a 9-yard TD pass to WR James Jones. In the second quarter, the Lions continued to trail as Rodgers completed a 2-yard TD pass to WR Donald Driver and a 29-yard TD pass to WR Jordy Nelson. Detroit closed out the first half when kicker Jason Hanson nailed a 38-yard field goal. In the third quarter, the Lions continued to hack away at Green Bay's lead with Hanson kicking 49-yard and then 53-yard field goals. The Packers responded when kicker Mason Crosby nailed a 25-yard field goal. In the fourth quarter, Detroit clawed away at the Pack's lead when QB Jon Kitna completed a 38-yard TD pass to WR Calvin Johnson. The Lions closed in as the snap to Packers punter Derrick Frost was high, causing it to go through the back of his end zone, giving Detroit a safety. The Lions took the lead on Kitna's 47-yard TD pass to Calvin Johnson. However, Green Bay rebounded with Crosby's 39-yard field goal, RB Brandon Jackson's 19-yard TD run, CB Charles Woodson's 41-yard interception return for a touchdown, and safety Nick Collins' 42-yard interception return for a touchdown.

Problem: Hoping to break a two-game losing streak, the Broncos traveled to Arrowhead Stadium for a AFC West rivalry rematch against the Kansas City Chiefs. The Broncos trailed in the first quarter, as Chiefs' quarterback Matt Cassel threw a 2-yard touchdown pass to tight end Leonard Pope, in what would be the game's only touchdown. The Broncos responded in the second quarter, with placekicker Matt Prater nailing a 25-yard field goal, but the Chiefs countered, with a 47-yard field goal by placekicker Ryan Succop just before halftime. After a scoreless third quarter, the Broncos cut into the lead with a 41-yard field goal by Prater, but Kansas City's defense prevented anything else from happening. With the loss, not only were the Broncos officially eliminated from postseason contention, but they also exceeded their loss total from their previous two seasons.

How many yards combined are the top two longest field goals?
Answer:
88
