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: Inside ornament was far more generous, and could sometimes be overwhelming. The chimneypiece continued to be the usual main focus of rooms, and was now given a classical treatment, and increasingly topped by a painting or a mirror. Plasterwork ceilings, carved wood, and bold schemes of wallpaint formed a backdrop to increasingly rich collections of furniture, paintings, porcelain, mirrors, and objets d'art of all kinds. Wood-panelling, very common since about 1500, fell from favour around the mid-century, and wallpaper included very expensive imports from China. Question: What type of ceilings became commonplace?
Answer:
Plasterwork ceilings
