Input: Read this: On 11 April 2006, Brian May and Roger Taylor appeared on the American singing contest television show American Idol. Each contestant was required to sing a Queen song during that week of the competition. Songs which appeared on the show included "Bohemian Rhapsody", "Fat Bottomed Girls", "The Show Must Go On", "Who Wants to Live Forever", and "Innuendo". Brian May later criticised the show for editing specific scenes, one of which made the group's time with contestant Ace Young look negative, despite it being the opposite. Taylor and May again appeared on the American Idol season 8 finale in May 2009, performing "We Are the Champions" with finalists Adam Lambert and Kris Allen. On 15 November 2009, Brian May and Roger Taylor appeared on the singing contest television show X Factor in the UK.

Input: Read this: Meetings for worship and study are held at Kingdom Halls, which are typically functional in character, and do not contain religious symbols. Witnesses are assigned to a congregation in whose "territory" they usually reside and attend weekly services they refer to as "meetings" as scheduled by congregation elders. The meetings are largely devoted to study of Watch Tower Society literature and the Bible. The format of the meetings is established by the religion's headquarters, and the subject matter for most meetings is the same worldwide. Congregations meet for two sessions each week comprising five distinct meetings that total about three-and-a-half hours, typically gathering mid-week (three meetings) and on the weekend (two meetings). Prior to 2009, congregations met three times each week; these meetings were condensed, with the intention that members dedicate an evening for "family worship". Gatherings are opened and closed with kingdom songs (hymns) and brief prayers. Twice each year, Witnesses from a number of congregations that form a "circuit" gather for a one-day assembly. Larger groups of congregations meet once a year for a three-day "regional convention", usually at rented stadiums or auditoriums. Their most important and solemn event is the commemoration of the "Lord's Evening Meal", or "Memorial of Christ's Death" on the date of the Jewish Passover.
Question: How many "circuits" are there of Kingdom Halls?

Output: unanswerable


Input: Read this: Above the main portal there is generally a large window, like that at York Minster, or a group of windows such as those at Ripon Cathedral. In France there is generally a rose window like that at Reims Cathedral. Rose windows are also often found in the façades of churches of Spain and Italy, but are rarer elsewhere and are not found on the façades of any English Cathedrals. The gable is usually richly decorated with arcading or sculpture or, in the case of Italy, may be decorated with the rest of the façade, with polychrome marble and mosaic, as at Orvieto Cathedral.
Question: What type of window is often found above the main portal at cathedrals in Greece such as the Reims Cathedral?

Input: Read this: The NES can be emulated on many other systems, most notably the PC. The first emulator was the Japanese-only Pasofami. It was soon followed by iNES, which was available in English and was cross-platform, in 1996. It was described as being the first NES emulation software that could be used by a non-expert. NESticle, a popular MS-DOS emulator, was released on April 3, 1997. There have since been many other emulators. The Virtual Console for the Wii, Nintendo 3DS and Wii U also offers emulation of many NES games.
