Problem: British Isles:

Many globally popular sports had modern rules codified in the British Isles, including golf, association football, cricket, rugby, snooker and darts, as well as many minor sports such as croquet, bowls, pitch and putt, water polo and handball. A number of sports are popular throughout the British Isles, the most prominent of which is association football. While this is organised separately in different national associations, leagues and national teams, even within the UK, it is a common passion in all parts of the islands. Rugby union is also widely enjoyed across the islands with four national teams from England, Ireland, Scotland and Wales. The British and Irish Lions is a team chosen from each national team and undertakes tours of the southern hemisphere rugby playing nations every four years. Ireland play as a united team, represented by players from both Northern Ireland and the Republic. These national rugby teams play each other each year for the Triple Crown as part of the Six Nations Championship. Also since 2001 the professional club teams of Ireland, Scotland, Wales and Italy compete against each other in the RaboDirect Pro12.

Problem: Canadian football:

Before scrimmage, an official places the ball at the spot it was at the stop of clock, but no nearer than 24 yards from the sideline or 1 yard from the goal line. The line parallel to the goal line passing through the ball (line from sideline to sideline for the length of the ball) is referred to as the line of scrimmage. This line is similar to "no-man's land"; players must stay on their respective sides of this line until the play has begun again. For a scrimmage to be valid the team in possession of the football must have seven players, excluding the quarterback, within one yard of the line of scrimmage. The defending team must stay a yard or more back from the line of scrimmage.

How many yards must the possessing team place near the line of scrimmage?

A: unanswerable

Problem: Great power:

China, France, Russia, the United Kingdom and the United States are often referred to as great powers by academics due to "their political and economic dominance of the global arena". These five nations are the only states to have permanent seats with veto power on the UN Security Council. They are also the only recognized "Nuclear Weapons States" under the Nuclear Non-Proliferation Treaty, and maintain military expenditures which are among the largest in the world. However, there is no unanimous agreement among authorities as to the current status of these powers or what precisely defines a great power. For example, sources have at times referred to China, France, Russia and the United Kingdom as middle powers.

What treaty addresses global political and economic dominance?
