The Arena Football League (AFL) is the highest level of professional indoor American football in the United States. It was founded in 1987 by Jim Foster, making it the third longest-running professional football league in North America, after the Canadian Football League and the National Football League. It is played indoors on a 68-yard field (about half the distance of an NFL field), resulting in a faster-paced and higher-scoring game. The sport was invented in the early 1980s and patented by Foster, a former executive of the United States Football League and the National Football League.
Where does the Arena Football League rank amongst professional football leagues in North America by longevity?
A: third

Other cities with a concentration of secular Gothic include Bruges and Siena. Most surviving small secular buildings are relatively plain and straightforward; most windows are flat-topped with mullions, with pointed arches and vaulted ceilings often only found at a few focal points. The country-houses of the nobility were slow to abandon the appearance of being a castle, even in parts of Europe, like England, where defence had ceased to be a real concern. The living and working parts of many monastic buildings survive, for example at Mont Saint-Michel.
Where are pointed arches and vaulted ceilings found on most secular Gothic structures?
A: a few focal points

The referee may punish a player's or substitute's misconduct by a caution (yellow card) or dismissal (red card). A second yellow card at the same game leads to a red card, and therefore to a dismissal. A player given a yellow card is said to have been "booked", the referee writing the player's name in his official notebook. If a player has been dismissed, no substitute can be brought on in their place. Misconduct may occur at any time, and while the offences that constitute misconduct are listed, the definitions are broad. In particular, the offence of "unsporting behaviour" may be used to deal with most events that violate the spirit of the game, even if they are not listed as specific offences. A referee can show a yellow or red card to a player, substitute or substituted player. Non-players such as managers and support staff cannot be shown the yellow or red card, but may be expelled from the technical area if they fail to conduct themselves in a responsible manner.
How many yellow cards lead to a blue card?
A: unanswerable

Ireland, the United Kingdom and the three Crown Dependencies are all parliamentary democracies, with their own separate parliaments. All parts of the United Kingdom return members to parliament in London. In addition to this, voters in Scotland, Wales and Northern Ireland return members to a parliament in Edinburgh and to assemblies in Cardiff and Belfast respectively. Governance in the norm is by majority rule, however, Northern Ireland uses a system of power sharing whereby unionists and nationalists share executive posts proportionately and where the assent of both groups are required for the Northern Ireland Assembly to make certain decisions. (In the context of Northern Ireland, unionists are those who want Northern Ireland to remain a part of the United Kingdom and nationalists are those who want Northern Ireland join with the rest of Ireland.) The British monarch is the head of state for all parts of the isles except for the Republic of Ireland, where the head of state is the President of Ireland.
What type of system does Southern Ireland use to make decisions?
A:
unanswerable
