Article: The British had already arranged licence building of the Bofors 40 mm, and introduced these into service. These had the power to knock down aircraft of any size, yet were light enough to be mobile and easily swung. The gun became so important to the British war effort that they even produced a movie, The Gun, that encouraged workers on the assembly line to work harder. The Imperial measurement production drawings the British had developed were supplied to the Americans who produced their own (unlicensed) copy of the 40 mm at the start of the war, moving to licensed production in mid-1941.

Question: While light, the Bofors 40mm were powerful enough to take down what size aircraft?
Ans: aircraft of any size

Article: Traditionally, major college basketball teams began their seasons with a few exhibition games. They played travelling teams made up of former college players on teams such as Athletes in Action or a team sponsored by Marathon Oil. On occasion before 1992, when FIBA allowed professional players on foreign national teams, colleges played those teams in exhibitions. However, in 2003, the National Collegiate Athletic Association banned games with non-college teams. Some teams have begun scheduling exhibition games against teams in NCAA Division II and NCAA Division III, or even against colleges and universities located in Canada. Major college basketball teams still travel to other countries during the summer to play in exhibition games, although a college team is allowed one foreign tour every four years, and a maximum of ten games in each tour.

Question: When did the FIBA stop allowing pros on foreign national teams?
Ans: 1992

Article: Much of the medieval period was a time of power struggles between competing dynasties such as the House of Savoy, the Visconti in northern Italy and the House of Habsburg in Austria and Slovenia. In 1291 to protect themselves from incursions by the Habsburgs, four cantons in the middle of Switzerland drew up a charter that is considered to be a declaration of independence from neighboring kingdoms. After a series of battles fought in the 13th, 14th and 15th centuries, more cantons joined the confederacy and by the 16th century Switzerland was well-established as a separate state.

Question: Much of the medieval period was a time of what?
