PROBLEM: Passage: In the following months, NATO took a wide range of measures to respond to the threat of terrorism. On 22 November 2002, the member states of the Euro-Atlantic Partnership Council (EAPC) decided on a Partnership Action Plan against Terrorism, which explicitly states, "EAPC States are committed to the protection and promotion of fundamental freedoms and human rights, as well as the rule of law, in combating terrorism." NATO started naval operations in the Mediterranean Sea designed to prevent the movement of terrorists or weapons of mass destruction as well as to enhance the security of shipping in general called Operation Active Endeavour.

PROBLEM: Passage: The KU men's basketball team has fielded a team every year since 1898. The Jayhawks are a perennial national contender currently coached by Bill Self. The team has won five national titles, including three NCAA tournament championships in 1952, 1988, and 2008. The basketball program is currently the second winningest program in college basketball history with an overall record of 2,070–806 through the 2011–12 season. The team plays at Allen Fieldhouse. Perhaps its best recognized player was Wilt Chamberlain, who played in the 1950s. Kansas has counted among its coaches Dr. James Naismith (the inventor of basketball and only coach in Kansas history to have a losing record), Basketball Hall of Fame inductee Phog Allen ("the Father of basketball coaching"), Basketball Hall of Fame inductee Roy Williams of the University of North Carolina at Chapel Hill, and Basketball Hall of Fame inductee and former NBA Champion Detroit Pistons coach Larry Brown. In addition, legendary University of Kentucky coach and Basketball Hall of Fame inductee Adolph Rupp played for KU's 1922 and 1923 Helms National Championship teams, and NCAA Hall of Fame inductee and University of North Carolina Coach Dean Smith played for KU's 1952 NCAA Championship team. Both Rupp and Smith played under Phog Allen. Allen also coached Hall of Fame coaches Dutch Lonborg and Ralph Miller. Allen founded the National Association of Basketball Coaches (NABC), which started what is now the NCAA Tournament. The Tournament began in 1939 under the NABC and the next year was handed off to the newly formed NCAA.

SOLUTION: What was the last year in which a men's team played basketball at the University of Kansas?
