The necessity and inerrancy were well-established ideas, garnering little criticism, though they later came under debate from outside during the Enlightenment. The most contentious idea at the time though was the notion that anyone could simply pick up the Bible and learn enough to gain salvation. Though the reformers were concerned with ecclesiology (the doctrine of how the church as a body works), they had a different understanding of the process in which truths in scripture were applied to life of believers, compared to the Catholics' idea that certain people within the church, or ideas that were old enough, had a special status in giving understanding of the text.
What group believes that some in the church have a special status to understand the bible?
Catholics

Input: Database
Database transactions can be used to introduce some level of fault tolerance and data integrity after recovery from a crash. A database transaction is a unit of work, typically encapsulating a number of operations over a database (e.g., reading a database object, writing, acquiring lock, etc.), an abstraction supported in database and also other systems. Each transaction has well defined boundaries in terms of which program/code executions are included in that transaction (determined by the transaction's programmer via special transaction commands).

How can database transactions ensure accuracy after a crash?
Output: fault tolerance

Problem: Dutch dialects and regional languages are not spoken as often as they used to be. Recent research by Geert Driessen shows that the use of dialects and regional languages among both Dutch adults and youth is in heavy decline. In 1995, 27 percent of the Dutch adult population spoke a dialect or regional language on a regular basis, while in 2011 this was no more than 11 percent. In 1995, 12 percent of the primary school aged children spoke a dialect or regional language, while in 2011 this had declined to 4 percent. Of the three officially recognized regional languages Limburgish is spoken most (in 2011 among adults 54%, among children 31%) and Dutch Low Saxon least (adults 15%, children 1%); Frisian occupies a middle position (adults 44%, children 22%).
How many primary school aged children were found to speak a dialect or regional language by 2011?
The answer is the following:
4 percent
