Question: Passage: Most of the Alsatian population is Roman Catholic, but, largely because of the region's German heritage, a significant Protestant community also exists: today, the EPCAAL (a Lutheran church) is France's second largest Protestant church, also forming an administrative union (UEPAL) with the much smaller Calvinist EPRAL. Unlike the rest of France, the Local law in Alsace-Moselle still provides for to the Napoleonic Concordat of 1801 and the organic articles, which provides public subsidies to the Roman Catholic, Lutheran, and Calvinist churches, as well as to Jewish synagogues; religion classes in one of these faiths is compulsory in public schools. This divergence in policy from the French majority is due to the region having been part of Imperial Germany when the 1905 law separating the French church and state was instituted (for a more comprehensive history, see: Alsace-Lorraine). Controversy erupts periodically on the appropriateness of this legal disposition, as well as on the exclusion of other religions from this arrangement.

Answer: What is the name of the second largest Roman Catholic church?


Question: Passage: After the World Cup, the most important international football competitions are the continental championships, which are organised by each continental confederation and contested between national teams. These are the European Championship (UEFA), the Copa América (CONMEBOL), African Cup of Nations (CAF), the Asian Cup (AFC), the CONCACAF Gold Cup (CONCACAF) and the OFC Nations Cup (OFC). The FIFA Confederations Cup is contested by the winners of all six continental championships, the current FIFA World Cup champions and the country which is hosting the Confederations Cup. This is generally regarded as a warm-up tournament for the upcoming FIFA World Cup and does not carry the same prestige as the World Cup itself. The most prestigious competitions in club football are the respective continental championships, which are generally contested between national champions, for example the UEFA Champions League in Europe and the Copa Libertadores in South America. The winners of each continental competition contest the FIFA Club World Cup.

Answer: What does UEFA Stand against?


Question: Passage: In their attempt to ensure white supremacy decades after emancipation, in the early 20th century, most southern states created laws based on the one-drop rule, defining as black, persons with any known African ancestry. This was a stricter interpretation than what had prevailed in the 19th century; it ignored the many mixed families in the state and went against commonly accepted social rules of judging a person by appearance and association. Some courts called it "the traceable amount rule." Anthropologists called it an example of a hypodescent rule, meaning that racially mixed persons were assigned the status of the socially subordinate group.

Answer:
What did southern states do to stop white supremacy?
