Problem: BeiDou Navigation Satellite System:

The second generation of the system, officially called the BeiDou Navigation Satellite System (BDS) and also known as COMPASS or BeiDou-2, will be a global satellite navigation system consisting of 35 satellites, and is under construction as of January 2015[update]. It became operational in China in December 2011, with 10 satellites in use, and began offering services to customers in the Asia-Pacific region in December 2012. It is planned to begin serving global customers upon its completion in 2020.

Problem: The debating societies discussed an extremely wide range of topics. Before the Enlightenment, most intellectual debates revolved around "confessional" that is, Catholic, Lutheran, Reformed (Calvinist), or Anglican issues, and the main aim of these debates was to establish which bloc of faith ought to have the "monopoly of truth and a God-given title to authority". After this date everything thus previously rooted in tradition was questioned and often replaced by new concepts in the light of philosophical reason. After the second half of the 17th century and during the 18th century, a "general process of rationalization and secularization set in," and confessional disputes were reduced to a secondary status in favor of the "escalating contest between faith and incredulity".
Catholic, Lutheran, Reformed (Calvinist), or Anglican issues were called what?

Answer: "confessional"

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The dates are generalizations, since the periods and eras overlap and the categories are somewhat arbitrary, to the point that some authorities reverse terminologies and refer to a common practice "era" comprising baroque, classical, and romantic "periods". For example, the use of counterpoint and fugue, which is considered characteristic of the Baroque era (or period), was continued by Haydn, who is classified as typical of the Classical era. Beethoven, who is often described as a founder of the Romantic era, and Brahms, who is classified as Romantic, also used counterpoint and fugue, but other characteristics of their music define their era.
Some authorities reverse terminologies to refer to the common practice period as a what?
A: era

Context and question: Federal law originates with the Constitution, which gives Congress the power to enact statutes for certain limited purposes like regulating interstate commerce. The United States Code is the official compilation and codification of the general and permanent federal statutes. Many statutes give executive branch agencies the power to create regulations, which are published in the Federal Register and codified into the Code of Federal Regulations. Regulations generally also carry the force of law under the Chevron doctrine. Many lawsuits turn on the meaning of a federal statute or regulation, and judicial interpretations of such meaning carry legal force under the principle of stare decisis.
Who do the statutes give the power of creating regulations?
Answer: executive branch agencies

Question: Thuringia generally accepted the Protestant Reformation, and Roman Catholicism was suppressed as early as 1520[citation needed]; priests who remained loyal to it were driven away and churches and monasteries were largely destroyed, especially during the German Peasants' War of 1525. In Muhlhausen and elsewhere, the Anabaptists found many adherents. Thomas Muntzer, a leader of some non-peaceful groups of this sect, was active in this city. Within the borders of modern Thuringia the Roman Catholic faith only survived in the Eichsfeld district, which was ruled by the Archbishop of Mainz, and to a small degree in Erfurt and its immediate vicinity.
Is there an answer to this question: When were most churches and monasteries protected?

Answer: unanswerable

Acute myocardial infarction refers to two subtypes of acute coronary syndrome, namely non-ST-elevated and ST-elevated MIs, which are most frequently (but not always) a manifestation of coronary artery disease. The most common triggering event is the disruption of an atherosclerotic plaque in an epicardial coronary artery, which leads to a clotting cascade, sometimes resulting in total occlusion of the artery. Atherosclerosis is the gradual buildup of cholesterol and fibrous tissue in plaques in the wall of arteries (in this case, the coronary arteries), typically over decades. Bloodstream column irregularities visible on angiography reflect artery lumen narrowing as a result of decades of advancing atherosclerosis. Plaques can become unstable, rupture, and additionally promote the formation of a blood clot that occludes the artery; this can occur in minutes. When a severe enough plaque rupture occurs in the coronary arteries, it leads to MI (necrosis of downstream myocardium). It is estimated that one billion cardiac cells are lost in a typical MI.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How long does an MI take?
Ah, so..
