Here is a question about this article: The first Armenian churches were built between the 4th and 7th century, beginning when Armenia converted to Christianity, and ending with the Arab invasion of Armenia. The early churches were mostly simple basilicas, but some with side apses. By the fifth century the typical cupola cone in the center had become widely used. By the seventh century, centrally planned churches had been built and a more complicated niched buttress and radiating Hrip'sime style had formed. By the time of the Arab invasion, most of what we now know as classical Armenian architecture had formed.
What is the answer to this question: When were Armenian churches built with niched buttresses?

Here is a question about this article: The Frankish kingdom in northern Gaul split into kingdoms called Austrasia, Neustria, and Burgundy during the 6th and 7th centuries, all of them ruled by the Merovingian dynasty, who were descended from Clovis. The 7th century was a tumultuous period of wars between Austrasia and Neustria. Such warfare was exploited by Pippin (d. 640), the Mayor of the Palace for Austrasia who became the power behind the Austrasian throne. Later members of his family inherited the office, acting as advisers and regents. One of his descendants, Charles Martel (d. 741), won the Battle of Poitiers in 732, halting the advance of Muslim armies across the Pyrenees.[K] Great Britain was divided into small states dominated by the kingdoms of Northumbria, Mercia, Wessex, and East Anglia, which were descended from the Anglo-Saxon invaders. Smaller kingdoms in present-day Wales and Scotland were still under the control of the native Britons and Picts. Ireland was divided into even smaller political units, usually known as tribal kingdoms, under the control of kings. There were perhaps as many as 150 local kings in Ireland, of varying importance.
What is the answer to this question: Along with Austrasia and Neustria, what kingdom was originally part of the Frankish kingdom?

So...
Burgundy
