Problem: Westminster Abbey:

The abbey became the coronation site of Norman kings. None were buried there until Henry III, intensely devoted to the cult of the Confessor, rebuilt the abbey in Anglo-French Gothic style as a shrine to venerate King Edward the Confessor and as a suitably regal setting for Henry's own tomb, under the highest Gothic nave in England. The Confessor's shrine subsequently played a great part in his canonisation. The work continued between 1245 and 1517 and was largely finished by the architect Henry Yevele in the reign of Richard II. Henry III also commissioned unique Cosmati pavement in front of the High Altar (the pavement has recently undergone a major cleaning and conservation programme and was re-dedicated by the Dean at a service on 21 May 2010).

What played a small role in King Edward the Confessor's canonisation?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1993, the city passed a massive redevelopment package known as the Metropolitan Area Projects (MAPS), intended to rebuild the city's core with civic projects to establish more activities and life to downtown. The city added a new baseball park; central library; renovations to the civic center, convention center and fairgrounds; and a water canal in the Bricktown entertainment district. Water taxis transport passengers within the district, adding color and activity along the canal. MAPS has become one of the most successful public-private partnerships undertaken in the U.S., exceeding $3 billion in private investment as of 2010. As a result of MAPS, the population living in downtown housing has exponentially increased, together with demand for additional residential and retail amenities, such as grocery, services, and shops.
What is one thing that was added in this project?
A: baseball park


Context and question: Unlike the American GPS, Russian GLONASS, and European Galileo systems, which use medium Earth orbit satellites, BeiDou-1 uses satellites in geostationary orbit. This means that the system does not require a large constellation of satellites, but it also limits the coverage to areas on Earth where the satellites are visible. The area that can be serviced is from longitude 70°E to 140°E and from latitude 5°N to 55°N. A frequency of the system is 2491.75 MHz.
BeiDou-1, along with European Galileo systems, use which type of satellites? 
Answer: unanswerable


Question: The term "Moors" has been used in Europe in a broader, somewhat derogatory sense to refer to Muslims, especially those of Arab or Berber descent, whether living in North Africa or Iberia. Moors were not a distinct or self-defined people. Medieval and early modern Europeans applied the name to Muslim Arabs, Berbers, Black Africans and Europeans alike.
Is there an answer to this question: What does the term "Moors" refer to?

Question: A revolution in 1332 resulted in a broad-based city government with participation of the guilds, and Strasbourg declared itself a free republic. The deadly bubonic plague of 1348 was followed on 14 February 1349 by one of the first and worst pogroms in pre-modern history: over a thousand Jews were publicly burnt to death, with the remainder of the Jewish population being expelled from the city. Until the end of the 18th century, Jews were forbidden to remain in town after 10 pm. The time to leave the city was signalled by a municipal herald blowing the Grüselhorn (see below, Museums, Musée historique);. A special tax, the Pflastergeld (pavement money), was furthermore to be paid for any horse that a Jew would ride or bring into the city while allowed to.
Is there an answer to this question: How many Jewish people avoided being publicly burnt to death?

Answer:
unanswerable
