[Q]: Extract the answer to the question from the following context. Question: What was the point of divergence of Presbyterian churches? Context: Presbyterians distinguish themselves from other denominations by doctrine, institutional organization (or "church order") and worship; often using a "Book of Order" to regulate common practice and order. The origins of the Presbyterian churches are in Calvinism. Many branches of Presbyterianism are remnants of previous splits from larger groups. Some of the splits have been due to doctrinal controversy, while some have been caused by disagreement concerning the degree to which those ordained to church office should be required to agree with the Westminster Confession of Faith, which historically serves as an important confessional document second only to the Bible, yet directing particularities in the standardization and translation of the Bible in Presbyterian churches.

[Q]: Extract the answer to the question from the following context. Question: what is the last time period mentioned? Context: In the Early Middle Ages, from the end of the 4th century, the western extent of modern-day Switzerland was part of the territory of the Kings of the Burgundians. The Alemanni settled the Swiss plateau in the 5th century and the valleys of the Alps in the 8th century, forming Alemannia. Modern-day Switzerland was therefore then divided between the kingdoms of Alemannia and Burgundy. The entire region became part of the expanding Frankish Empire in the 6th century, following Clovis I's victory over the Alemanni at Tolbiac in 504 AD, and later Frankish domination of the Burgundians.

[Q]: Extract the answer to the question from the following context. Question: Which building was completed first, the Palais Rohan or the Hotel de Klinglin? Context: The German Renaissance has bequeathed the city some noteworthy buildings (especially the current Chambre de commerce et d'industrie, former town hall, on Place Gutenberg), as did the French Baroque and Classicism with several hotels particuliers (i.e. palaces), among which the Palais Rohan (1742, now housing three museums) is the most spectacular. Other buildings of its kind are the "Hotel de Hanau" (1736, now the city hall), the Hotel de Klinglin (1736, now residence of the prefet), the Hotel des Deux-Ponts (1755, now residence of the military governor), the Hotel d'Andlau-Klinglin (1725, now seat of the administration of the Port autonome de Strasbourg) etc. The largest baroque building of Strasbourg though is the 150 m (490 ft) long 1720s main building of the Hopital civil. As for French Neo-classicism, it is the Opera House on Place Broglie that most prestigiously represents this style.

[Q]: Extract the answer to the question from the following context. Question: Backup files are tied to? Context: Sometimes it is desired to bring a database back to a previous state (for many reasons, e.g., cases when the database is found corrupted due to a software error, or if it has been updated with erroneous data). To achieve this a backup operation is done occasionally or continuously, where each desired database state (i.e., the values of its data and their embedding in database's data structures) is kept within dedicated backup files (many techniques exist to do this effectively). When this state is needed, i.e., when it is decided by a database administrator to bring the database back to this state (e.g., by specifying this state by a desired point in time when the database was in this state), these files are utilized to restore that state.
