Problem: 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.

How many more percentage points of the elephant population was lost in savannah populations in Cameroon and Somalia than African forest elephants?
Answer: 37

Problem: Trying to snap their three-game losing streak, the Lions flew to Gillette Stadium for a Week 13 fight with the New England Patriots. In the first quarter, Detroit trailed early as kicker Stephen Gostkowski nailed a 25-yard field goal for the only score of the period. In the second quarter, the Lions took the lead with QB Jon Kitna completing a 5-yard TD pass to WR Mike Furrey, while kicker Jason Hanson got a 29-yard field goal. However, New England would reclaim the lead with RB Corey Dillon's 6-yard TD run and Gostkowski's 27-yard field goal. In the third quarter, Detroit came right back with Hanson's 38-yard and 49-yard field goal, while DE Jared DeVries sacked Pats QB Tom Brady in his endzone for a safety. In the fourth quarter, Hanson would kick a 26-yard field goal. However, their lead would vanish for good, as Dillon got a 2-yard TD run, which was followed up with Brady successfully completing a 2-point conversion pass to WR Troy Brown. Dillon would then wrap the game up with a 4-yard TD run. With their fourth-straight loss, the Lions fell to 2-10.

Which player scored more field goals, Jason Hanson or Stephen Gostkowski?
Answer: Jason Hanson

Problem: After the loss to the Bengals, the Pittsburgh Steelers journeyed to Arrowhead Stadium for a match with the Chiefs. At the start of the first quarter Chiefs RB Jamaal Charles returned a kickoff from their own 3-yard line to the Steelers' endzone for a touchdown. In the second quarter Pittsburgh rallied as PK Jeff Reed made a 36-yard field goal, then QB Ben Roethlisberger made an 8-yard touchdown pass to WR Hines Ward, and then Roethlisberger passed to TE Heath Miller 10yards for a touchdown. In the third quarter the Chiefs tied the game when QB Matt Cassel made a 21-yard touchdown pass to TE Leonard Pope, and then kicker Ryan Succop made a 22-yard field goal. In the fourth quarter Pittsburgh took the lead as QB Ben Roethlisberger made an 8-yard touchdown pass to RB Rashard Mendenhall, until the Chiefs came back to tie the game as QB Matt Cassel made a two-yard touchdown pass to Jamaal Charles to put the game in overtime. Afterwards, it was Kansas City that took the win when kicker Ryan Succop made a 22-yard field goal.

How many points did the Chiefs have to win?
Answer: 27

Problem: British colonial rule in the region of modern-day Malawi, where the revolt occurred, began between 1899 and 1900, when the British sought to increase their formal control over the territory to preempt encroachment by German or Portuguese colonial empires. The region became a British protectorate in 1891 and in 1907, was named Nyasaland. Unlike many other parts of Africa, where British rule was dependent on the support of local factions, in Nyasaland British control rested on military superiority. During the 1890s the colonial authorities put down numerous rebellions by the local Yao, Ngoni and Cewa peoples. British rule in Nyasaland radically altered the local indigenous power structures. The early colonial period saw some immigration and settlement by white colonists, who bought large swathes of territory from local chiefs, often for token payments in beads or guns. Most of the land acquired, particularly in the Shire Highlands, was converted into white-owned plantations where tea, coffee, cotton and tobacco were grown. The enforcement of colonial institutions, such as the Hut Tax, compelled many indigenous people to find paid work and the demand for labour created by the plantations, led to their becoming a major employer. Once employed on the plantations, black workers found that they were frequently beaten and subject to racial discrimination. Increasingly, the plantations were also forced to rely on a system of forced labour or corvee, known locally at the thangata.

How many major crops were grown on white owned plantations?
Answer:
4
