Problem: There are many styles of mandolin, but four are common, the Neapolitan or round-backed mandolin, the carved-top mandolin and the flat-backed mandolin. The round-back has a deep bottom, constructed of strips of wood, glued together into a bowl. The carved-top or arch-top mandolin has a much shallower, arched back, and an arched top—both carved out of wood. The flat-backed mandolin uses thin sheets of wood for the body, braced on the inside for strength in a similar manner to a guitar. Each style of instrument has its own sound quality and is associated with particular forms of music. Neapolitan mandolins feature prominently in European classical music and traditional music. Carved-top instruments are common in American folk music and bluegrass music. Flat-backed instruments are commonly used in Irish, British and Brazilian folk music. Some modern Brazilian instruments feature an extra fifth course tuned a fifth lower than the standard fourth course.
Which mandolin is commin in American Folk music and blue grass music?

Answer: Carved-top instruments


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Industrial Revolution in the Midlands and Northern England spelled the end for most of Somerset's cottage industries. Farming continued to flourish, however, and the Bath and West of England Society for the Encouragement of Agriculture, Arts, Manufactures and Commerce was founded in 1777 to improve farming methods. Despite this, 20 years later John Billingsley conducted a survey of the county's agriculture in 1795 and found that agricultural methods could still be improved. Coal mining was an important industry in north Somerset during the 18th and 19th centuries, and by 1800 it was prominent in Radstock. The Somerset Coalfield reached its peak production by the 1920s, but all the pits have now been closed, the last in 1973. Most of the surface buildings have been removed, and apart from a winding wheel outside Radstock Museum, little evidence of their former existence remains. Further west, the Brendon Hills were mined for iron ore in the late 19th century; this was taken by the West Somerset Mineral Railway to Watchet Harbour for shipment to the furnaces at Ebbw Vale.
In what year was the Somerset Coalfield established?
A: unanswerable


Context and question: According to Eurostat, Greece's largest port by tons of goods transported in 2010 is the port of Aghioi Theodoroi, with 17.38 million tons. The Port of Thessaloniki comes second with 15.8 million tons, followed by the Port of Piraeus, with 13.2 million tons, and the port of Eleusis, with 12.37 million tons. The total number of goods transported through Greece in 2010 amounted to 124.38 million tons, a considerable drop from the 164.3 million tons transported through the country in 2007.

In 2013, Piraeus was declared the fastest-growing port in the world.
What was the port of Piraeus declared to be in 2013?

Question: Soon after the passing of the 1931 Act, in the book published on the occasion of the Institute's centenary celebration in 1934, Harry Barnes, FRIBA, Chairman of the Registration Committee, mentioned that ARCUK could not be a rival of any architectural association, least of all the RIBA, given the way ARCUK was constituted. Barnes commented that the Act's purpose was not protecting the architectural profession, and that the legitimate interests of the profession were best served by the (then) architectural associations in which some 80 per cent of those practising architecture were to be found.
Is there an answer to this question: What specific institution did Barnes indicate could become a rival of the Royal Institute?

Answer: unanswerable
