Problem: Dominican Order:

The spiritual tradition of Dominic's Order is punctuated not only by charity, study and preaching, but also by instances of mystical union. The Dominican emphasis on learning and on charity distinguishes it from other monastic and mendicant orders. As the order first developed on the European continent, learning continued to be emphasized by these friars and their sisters in Christ.

Problem: Gothic architecture:

From the 10th to the 13th century, Romanesque architecture had become a pan-European style and manner of construction, affecting buildings in countries as far apart as Ireland, Croatia, Sweden and Sicily. The same wide geographic area was then affected by the development of Gothic architecture, but the acceptance of the Gothic style and methods of construction differed from place to place, as did the expressions of Gothic taste. The proximity of some regions meant that modern country borders do not define divisions of style. On the other hand, some regions such as England and Spain produced defining characteristics rarely seen elsewhere, except where they have been carried by itinerant craftsmen, or the transfer of bishops. Regional differences that are apparent in the great abbey churches and cathedrals of the Romanesque period often become even more apparent in the Gothic.

What is the only country in the geographic area that was affected by the development of the Gothic style of architecture?
---
A: unanswerable
