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.

What are the four common styles of mandolins?
Answer: the Neapolitan or round-backed mandolin, the carved-top mandolin and the flat-backed mandolin.


Problem: Although Bell was, and still is, accused of stealing the telephone from Gray, Bell used Gray's water transmitter design only after Bell's patent had been granted, and only as a proof of concept scientific experiment, to prove to his own satisfaction that intelligible "articulate speech" (Bell's words) could be electrically transmitted. After March 1876, Bell focused on improving the electromagnetic telephone and never used Gray's liquid transmitter in public demonstrations or commercial use.
Bell used his own design in all public demonstrations and what?
The answer is the following: commercial use


Napoleon could be considered one of the founders of modern Germany. After dissolving the Holy Roman Empire, he reduced the number of German states from 300 to less than 50, paving the way to German Unification. A byproduct of the French occupation was a strong development in German nationalism. Napoleon also significantly aided the United States when he agreed to sell the territory of Louisiana for 15 million dollars during the presidency of Thomas Jefferson. That territory almost doubled the size of the United States, adding the equivalent of 13 states to the Union.
How many German states remained after Napoleon reduced their numbers?
less than 50


Input: Muammar Gaddafi
Libya began to turn towards socialism. In March 1978, the government issued guidelines for housing redistribution, attempting to ensure the population that every adult Libyan owned his own home and that nobody was enslaved to paying their rent. Most families were banned from owning more than one house, while former rental properties were seized and sold to the tenants at a heavily subsidized price. In September, Gaddafi called for the People's Committees to eliminate the "bureaucracy of the public sector" and the "dictatorship of the private sector"; the People's Committees took control of several hundred companies, converting them into worker cooperatives run by elected representatives.

In September of 1978, what bureaucracy did Gaddafi speak out against?
Output: public sector


Input: Article: Construction of the chapel, originally intended to be slightly over twice as long, with eighteen - or possibly seventeen - bays (there are eight today) was stopped when Henry VI was deposed. Only the Quire of the intended building was completed. Eton's first Headmaster, William Waynflete, founder of Magdalen College, Oxford and previously Head Master of Winchester College, built the ante-chapel that finishes the Chapel today. The important wall paintings in the Chapel and the brick north range of the present School Yard also date from the 1480s; the lower storeys of the cloister, including College Hall, had been built between 1441 and 1460.

Now answer this question: How many bays was the chapel originially intended to have?

Output: eighteen - or possibly seventeen
