P: African elephants were listed as Vulnerable species by the International Union for Conservation of Nature (IUCN) in 2008, with no independent assessment of the conservation status of the two forms. In 1979, Africa had an estimated minimum population of 1.3 million elephants, with a possible upper limit of 3.0 million. By 1989, the population was estimated to be 609,000; with 277,000 in Central Africa, 110,000 in East Africa, 204,000 in southern Africa, and 19,000 in West Africa. About 214,000 elephants were estimated to live in the rainforests, fewer than had previously been thought. From 1977 to 1989, elephant populations declined by 74% in East Africa. After 1987, losses in elephant numbers accelerated, and savannah populations from Cameroon to Somalia experienced a decline of 80%. African forest elephants had a total loss of 43%. Population trends in southern Africa were mixed, with anecdotal reports of losses in Zambia, Mozambique and Angola while populations grew in Botswana and Zimbabwe and were stable in South Africa. Conversely, studies in 2005 and 2007 found populations in eastern and southern Africa were increasing by an average annual rate of 4.0%. Due to the vast areas involved, assessing the total African elephant population remains difficult and involves an element of guesswork. The IUCN estimates a total of around 440,000 individuals for 2012.
Answer this: How many is the difference between the upper limit of elephants in Africa and the minimum?

A: 1.7
Problem: Coming off their win over the Cardinals the Chiefs flew to Qwest Field where they played their old division rival, the Seattle Seahawks.  In the first quarter, the Chiefs took the lead with QB Matt Cassel getting a 7-yard TD pass to WR Dwayne Bowe.  They had a problem maintaining this lead as Dustin Colquitt's punt was blocked and returned 10 yards for a touchdown by FS Earl Thomas.  They soon got the lead back as Shaun Smith got a 1-yard TD run, followed by Cassel finding Bowe again on a 36-yard TD pass.  The lead was narrowed when kicker Olindo Mare got a 43-yard field goal, followed by QB Matt Hasselbeck getting a 13-yard TD pass to TE Chris Baker. The Chiefs pulled ahead with RB Jamaal Charles getting a 3-yard TD run, followed by Cassel throwing to Bowe on a 9-yard TD pass.  The Seahawks responded as Hasselbeck completed an 87-yard TD pass to WR Ben Obomanu, but the Chiefs increased their lead as Cassel got a 6-yard TD pass to TE Tony Moeaki.

How many yards difference was Matt Hasselbeck’s touchdown pass to Chris Baker compared to Matt Cassel’s touchdown pass to Tony Moeaki?
Answer: 7
Q: Coming off their bye week, the Broncos went home for a Week 9 duel with the Miami Dolphins.  In the first quarter, Denver trailed early as Dolphins kicker Dan Carpenter got a 45-yard and a 47-yard field goal, along with CB Will Allen returning an interception 32 yards for a touchdown.  The Broncos would answer with QB Jay Cutler completing a 2-yard TD pass to rookie WR Eddie Royal.  In the second quarter, Miami answered with Carpenter getting a 23-yard field goal. In the third quarter, Denver tried to rally as kicker Matt Prater got a 50-yard field goal.  In the fourth quarter, the Dolphins replied with Carpenter nailing a 41-yard field goal.  The Broncos tried to come back as Cutler completed a 1-yard TD pass to rookie FB Peyton Hillis.  However, Miami pulled away as RB Ronnie Brown got a 2-yard TD run.
How many more field goals did Carpenter kick than Prater?
A: 3
Problem: Razin's parents were from the village of Usman Sobakina, 8 kilometres  outside of Voronezh. He was first noted by history in 1661, as part of a diplomatic mission from the Don Cossacks to the Kalmyks. That same year Razin went on a long-distance pilgrimage to the great Solovetsky Monastery on the White Sea for the benefit of his soul. After that, all trace of him was lost for six years, when he reappeared as the leader of a robber community established at Panshinskoye, among the marshes between the rivers Tishina and Ilovlya, from whence he levied tribute from all vessels passing up and down the Volga. A long war with Poland in 1654-1667 and Sweden in 1656-1658 put heavy demands upon the people of Russia. Taxes increased, as did conscription. Many peasants, hoping to escape these burdens, fled south and joined bands of Razin's marauding Cossacks. They were also joined by many others who were disaffected with the Russian government, including people of the lower classes, as well as representatives of non-Russian ethnic groups such as Kalmyks, that were being oppressed at the time. Razin's first considerable exploit was to destroy the great naval convoy consisting of the treasury barges and the barges of the Patriarch and the wealthy merchants of Moscow. Razin then sailed down the Volga with a fleet of 35 vessels, capturing the more important forts on his way and devastating the country. At the beginning of 1668, he defeated the voivode Yakov Bezobrazov, sent against him from Astrakhan, and in the spring embarked on a predatory expedition into Daghestan and Persia, which lasted for eighteen months.

P: Over one and half year after Super Bowl XLIX, the Seahawks were trying to get their revenge against the Patriots after the heartbreaking interception. They successfully got their revenge by stopping the Patriots from getting into the end zone, and won the game 31-24. The Seahawks were the only team to defeat the Patriots under Tom Brady during this season (their one other loss, against the Buffalo Bills in Week 4, happened during Brady's suspension for the Deflategate scandal). This also marks Pete Carroll's first return to Boston since 1999 after he got fired from the Patriots organization.
