Question: The City Planning Commission, tasked with guiding growth and development of the city, has divided the city into 18 planning districts as part of the Philadelphia2035 physical development plan. Much of the city's 1980 zoning code was overhauled from 20072012 as part of a joint effort between former mayors John F. Street and Michael Nutter. The zoning changes were intended to rectify incorrect zoning mapping that would streamline future community preferences and development, which the city forecasts an additional 100,000 residents and 40,000 jobs to be added to Philadelphia in 2035.
Is there an answer to this question: How many planning districts make up Philadelphia?

Answer: 18

Question: A year before Alfonso III "the Great" of Asturias death, three of Alfonso's sons rose in rebellion and forced him to abdicate, partitioning the kingdom among them. The eldest son, Garcia, became king of Leon. The second son, Ordono, reigned in Galicia, while the third, Fruela, received Asturias with Oviedo as his capital. Alfonso died in Zamora, probably in 910. His former realm would be reunited when first Garcia died childless and Leon passed to Ordono. He in turn died when his children were too young to ascend; Fruela became king of a reunited crown. His death the next year initiated a series of internecine struggles that led to unstable succession for over a century. It continued under that name[clarification needed] until incorporated into the Kingdom of Castile in 1230, after Ferdinand III became joint king of the two kingdoms. This was done to avoid dynastic feuds and to maintain the Christian Kingdoms strong enough to prevent complete Muslim take over of the Iberian Peninsula and to further the Reconquista of Iberia by Christian armies.
Is there an answer to this question: In which year did Alfonso III likely die?

Answer: 910

Question: This situation prevailed until 1639, when most of Alsace was conquered by France so as to keep it out of the hands of the Spanish Habsburgs, who wanted a clear road to their valuable and rebellious possessions in the Spanish Netherlands. Beset by enemies and seeking to gain a free hand in Hungary, the Habsburgs sold their Sundgau territory (mostly in Upper Alsace) to France in 1646, which had occupied it, for the sum of 1.2 million Thalers. When hostilities were concluded in 1648 with the Treaty of Westphalia, most of Alsace was recognized as part of France, although some towns remained independent. The treaty stipulations regarding Alsace were complex; although the French king gained sovereignty, existing rights and customs of the inhabitants were largely preserved. France continued to maintain its customs border along the Vosges mountains where it had been, leaving Alsace more economically oriented to neighbouring German-speaking lands. The German language remained in use in local administration, in schools, and at the (Lutheran) University of Strasbourg, which continued to draw students from other German-speaking lands. The 1685 Edict of Fontainebleau, by which the French king ordered the suppression of French Protestantism, was not applied in Alsace. France did endeavour to promote Catholicism; Strasbourg Cathedral, for example, which had been Lutheran from 1524 to 1681, was returned to the Catholic Church. However, compared to the rest of France, Alsace enjoyed a climate of religious tolerance.
