Problem: Given the inaccessibility of much of the species range, particularly the central Amazon, estimating jaguar numbers is difficult. Researchers typically focus on particular bioregions, thus species-wide analysis is scant. In 1991, 600-1,000 (the highest total) were estimated to be living in Belize. A year earlier, 125-180 jaguars were estimated to be living in Mexicos 4,000-km2 (2400-mi2) Calakmul Biosphere Reserve, with another 350 in the state of Chiapas. The adjoining Maya Biosphere Reserve in Guatemala, with an area measuring 15,000 km2 (9,000 mi2), may have 465-550 animals. Work employing Global Positioning System telemetry in 2003 and 2004 found densities of only six to seven jaguars per 100 km2 in the critical Pantanal region, compared with 10 to 11 using traditional methods; this suggests the widely used sampling methods may inflate the actual numbers of cats.

How many more km2 is the Maya Biosphere Reserve in Guatemala than the Mexicos Calakmul Biosphere Reserve?
Answer: 11000

Problem: Trying to snap a four-game skid, the Lions went home for an NFC North rematch with the Minnesota Vikings. In the first quarter, the Lions trailed as Vikings RB Artose Pinner (a former Lion) got a 3-yard and a 4-yard TD run. In the second quarter, Detroit's struggles continued as Vikes QB Brad Johnson got a 3-yard TD run, yet the 2-point conversion failed. Afterwards, the Lions finally got on the board with DB Jamar Fletcher returning an interception 88 yards for a touchdown, while kicker Jason Hanson nailed a 53-yard field goal. In the third quarter, Detroit held Minnesota to a 30-yard field goal by kicker Ryan Longwell, while Hanson kicked a 45-yard field goal. In the fourth quarter, Pinner wrapped things up for the Vikings with a 1-yard TD run. Even though the Lions would get a touchdown, from QB Jon Kitna's 23-yard strike to RB Kevin Jones, Detroit was plagued with 6 turnovers. They pulled within 10 in the 4th qtr and had a fourth and goal with less than four minutes to play. Needing two scores, inexplicably the Lions went for a touchdown and failed, thus killing any hope for a last minute victory. With their fifth-straight loss, the Lions fell to 2-11.

How many field goals did Jason Hanson kick in the second quarter?
Answer: 1

Problem: Religious freedom is constitutionally provided for in Ireland. Christianity is the predominant religion, and while Ireland remains a predominantly Catholic country, the percentage of the population who identified as Catholic on the census has fallen sharply from 84.2 percent in the 2011 census to 78.3 percent in the most recent 2016 census. Other results from the 2016 census are: 4.2% Protestant, 1.3% as Muslim, and 9.8% as having no religion. According to a Georgetown University study, before 2000 the country had one of the highest rates of regular Mass attendance in the Western world.While daily attendance was 13% in 2006, there was a reduction in weekly attendance from 81% in 1990 to 48% in 2006, although the decline was reported as stabilising. In 2011, it was reported that weekly Mass attendance in Dublin was just 18%, with it being even lower among younger generations.

How many percent did the number of Catholics fall from the 2011 to the 2016 census?
Answer: 5.9
