This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.

Let me give you an example: Passage: The French and Indian War (17541763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict. Question: When was the French and Indian War?
The answer to this example can be: 1754-1763
Here is why: It is a common convention to write (start year-end year) beside a historical event to understand when the event happened. We can observe a similar notation from the passage to conclude that the French and Indian War happened during 17541763. Therefore, the answer is 17541763.

OK. solve this:
Passage: In the 10th century the establishment of churches and monasteries led to the development of stone architecture that elaborated vernacular Roman forms, from which the term "Romanesque" is derived. Where available, Roman brick and stone buildings were recycled for their materials. From the tentative beginnings known as the First Romanesque, the style flourished and spread across Europe in a remarkably homogeneous form. Just before 1000 there was a great wave of building stone churches all over Europe. Romanesque buildings have massive stone walls, openings topped by semi-circular arches, small windows, and, particularly in France, arched stone vaults. The large portal with coloured sculpture in high relief became a central feature of facades, especially in France, and the capitals of columns were often carved with narrative scenes of imaginative monsters and animals. According to art historian C. R. Dodwell, "virtually all the churches in the West were decorated with wall-paintings", of which few survive. Simultaneous with the development in church architecture, the distinctive European form of the castle was developed, and became crucial to politics and warfare. Question: Who noted the prevalence of wall-paintings in Western churches of this era?
Answer:
C. R. Dodwell
