PROBLEM: Passage: New Zealand has a strong hunting culture. The islands making up New Zealand originally had no land mammals apart from bats. However, once Europeans arrived, game animals were introduced by acclimatisation societies to provide New Zealanders with sport and a hunting resource. Deer, pigs, goats, rabbits, hare, tahr and chamois all adapted well to the New Zealand terrain, and with no natural predators, their population exploded. Government agencies view the animals as pests due to their effects on the natural environment and on agricultural production, but hunters view them as a resource.

SOLUTION: What mammal was the only one that existed originally in Europe?

PROBLEM: Passage: KU football dates from 1890, and has played in the Orange Bowl three times: 1948, 1968, and 2008. They are currently coached by David Beaty, who was hired in 2014. In 2008, under the leadership of Mark Mangino, the #7 Jayhawks emerged victorious in their first BCS bowl game, the FedEx Orange Bowl, with a 24–21 victory over the #3 Virginia Tech Hokies. This capstone victory marked the end of the most successful season in school history, in which the Jayhawks went 12–1 (.923). The team plays at Memorial Stadium, which recently underwent a $31 million renovation to add the Anderson Family Football Complex, adding a football practice facility adjacent to the stadium complete with indoor partial practice field, weight room, and new locker room.

SOLUTION:
When did KU stop fielding a football team?
