Problem: Age of Enlightenment:

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".

During what time period did a "general process of rationalization and secularization set in"?

A: second half of the 17th century and during the 18th century

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
It was principally the widespread introduction of a single feature, the pointed arch, which was to bring about the change that separates Gothic from Romanesque. The technological change permitted a stylistic change which broke the tradition of massive masonry and solid walls penetrated by small openings, replacing it with a style where light appears to triumph over substance. With its use came the development of many other architectural devices, previously put to the test in scattered buildings and then called into service to meet the structural, aesthetic and ideological needs of the new style. These include the flying buttresses, pinnacles and traceried windows which typify Gothic ecclesiastical architecture. But while pointed arch is so strongly associated with the Gothic style, it was first used in Western architecture in buildings that were in other ways clearly Romanesque, notably Durham Cathedral in the north of England, Monreale Cathedral and Cathedral of Cefalu in Sicily, Autun Cathedral in France.
What is the name of the cathedral in Sicily that first displayed the use of the twisted arch?
A: unanswerable

Context and question: Each of these four dialects was associated with an independent kingdom on the island. Of these, Northumbria south of the Tyne, and most of Mercia, were overrun by the Vikings during the 9th century. The portion of Mercia that was successfully defended, and all of Kent, were then integrated into Wessex under Alfred the Great. From that time on, the West Saxon dialect (then in the form now known as Early West Saxon) became standardised as the language of government, and as the basis for the many works of literature and religious materials produced or translated from Latin in that period.
Along with the part of Mercia not conquered by the Vikings, what other kingdom was combined with Wessex by Alfred?
Answer: Kent

Question: The Ottoman Islamic legal system was set up differently from traditional European courts. Presiding over Islamic courts would be a Qadi, or judge. Since the closing of the ijtihad, or Gate of Interpretation, Qadis throughout the Ottoman Empire focused less on legal precedent, and more with local customs and traditions in the areas that they administered. However, the Ottoman court system lacked an appellate structure, leading to jurisdictional case strategies where plaintiffs could take their disputes from one court system to another until they achieved a ruling that was in their favor.
Is there an answer to this question: At what juncture did the Qadi focus less on precedent?

Answer: closing of the ijtihad, or Gate of Interpretation

QUES: Independent service is a special service mode found on most elevators. It is activated by a key switch either inside the elevator itself or on a centralized control panel in the lobby. When an elevator is placed on independent service, it will no longer respond to hall calls. (In a bank of elevators, traffic is rerouted to the other elevators, while in a single elevator, the hall buttons are disabled). The elevator will remain parked on a floor with its doors open until a floor is selected and the door close button is held until the elevator starts to travel. Independent service is useful when transporting large goods or moving groups of people between certain floors.

How is the special sercice mode enabled?
