Problem: United States dollar:

The value of the U.S. dollar declined significantly during wartime, especially during the American Civil War, World War I, and World War II. The Federal Reserve, which was established in 1913, was designed to furnish an "elastic" currency subject to "substantial changes of quantity over short periods", which differed significantly from previous forms of high-powered money such as gold, national bank notes, and silver coins. Over the very long run, the prior gold standard kept prices stablefor instance, the price level and the value of the U.S. dollar in 1914 was not very different from the price level in the 1880s. The Federal Reserve initially succeeded in maintaining the value of the U.S. dollar and price stability, reversing the inflation caused by the First World War and stabilizing the value of the dollar during the 1920s, before presiding over a 30% deflation in U.S. prices in the 1930s.

During which times does the value of the dollar typically maintain value?

Problem: There are a variety of watersports in Cork, including rowing and sailing. There are five rowing clubs training on the river Lee, including Shandon BC, UCC RC, Pres RC, Lee RC, and Cork BC. Naomhoga Chorcai is a rowing club whose members row traditional naomhoga on the Lee in occasional competitions. The "Ocean to City" race has been held annually since 2005, and attracts teams and boats from local and visiting clubs who row the 24 kilometres (15 mi) from Crosshaven into Cork city centre. The decision to move the National Rowing Center to Inniscarra has boosted numbers involved in the sport.[citation needed] Cork's maritime sailing heritage is maintained through its sailing clubs. The Royal Cork Yacht Club located in Crosshaven (outside the city) is the world's oldest yacht club, and "Cork Week" is a notable sailing event.

Context and question: From about 1800 a fresh influx of Greek architectural examples, seen through the medium of etchings and engravings, gave a new impetus to neoclassicism, the Greek Revival. There was little to no direct knowledge of Greek civilization before the middle of the 18th century in Western Europe, when an expedition funded by the Society of Dilettanti in 1751 and led by James Stuart and Nicholas Revett began serious archaeological enquiry. Stuart was commissioned after his return from Greece by George Lyttelton to produce the first Greek building in England, the garden temple at Hagley Hall (175859). A number of British architects in the second half of the century took up the expressive challenge of the Doric from their aristocratic patrons, including Joseph Bonomi and John Soane, but it was to remain the private enthusiasm of connoisseurs up to the first decade of the 19th century.
What was the first Greek building in Western Europe?
