The problem: Answer a question about this article:
All of the executions which have taken place since the 1936 hanging of Bethea in Owensboro have been conducted within a wall or enclosure. For example, Fred Adams was legally hanged in Kennett, Missouri, on April 2, 1937, within a 10-foot (3 m) wooden stockade. Roscoe "Red" Jackson was hanged within a stockade in Galena, Missouri, on May 26, 1937. Two Kentucky hangings were conducted after Galena in which numerous persons were present within a wooden stockade, that of John "Peter" Montjoy in Covington, Kentucky on December 17, 1937, and that of Harold Van Venison in Covington on June 3, 1938. An estimated 400 witnesses were present for the hanging of Lee Simpson in Ryegate, Montana, on December 30, 1939. The execution of Timothy McVeigh on June 11, 2001 was witnessed by some 300 people, some by closed-circuit television.
On what date was Fred Adams hanged?
****
The answer: April 2, 1937


Problem: Please answer a question about the following article about Dell:
Dell previously had its headquarters in the Arboretum complex in northern Austin, Texas. In 1989 Dell occupied 127,000 square feet (11,800 m2) in the Arboretum complex. In 1990, Dell had 1,200 employees in its headquarters. In 1993, Dell submitted a document to Round Rock officials, titled "Dell Computer Corporate Headquarters, Round Rock, Texas, May 1993 Schematic Design." Despite the filing, during that year the company said that it was not going to move its headquarters. In 1994, Dell announced that it was moving most of its employees out of the Arboretum, but that it was going to continue to occupy the top floor of the Arboretum and that the company's official headquarters address would continue to be the Arboretum. The top floor continued to hold Dell's board room, demonstration center, and visitor meeting room.

Problem: With the help of Charles Stearn, an expert on vacuum pumps, in 1878, Swan developed a method of processing that avoided the early bulb blackening. This received a British Patent in 1880.[dubious – discuss] On 18 December 1878, a lamp using a slender carbon rod was shown at a meeting of the Newcastle Chemical Society, and Swan gave a working demonstration at their meeting on 17 January 1879. It was also shown to 700 who attended a meeting of the Literary and Philosophical Society of Newcastle upon Tyne on 3 February 1879. These lamps used a carbon rod from an arc lamp rather than a slender filament. Thus they had low resistance and required very large conductors to supply the necessary current, so they were not commercially practical, although they did furnish a demonstration of the possibilities of incandescent lighting with relatively high vacuum, a carbon conductor, and platinum lead-in wires. Besides requiring too much current for a central station electric system to be practical, they had a very short lifetime. Swan turned his attention to producing a better carbon filament and the means of attaching its ends. He devised a method of treating cotton to produce 'parchmentised thread' and obtained British Patent 4933 in 1880. From this year he began installing light bulbs in homes and landmarks in England. His house was the first in the world to be lit by a lightbulb and also the first house in the world to be lit by hydroelectric power. In 1878 the home of Lord Armstrong at Cragside was also among the first houses to be lit by electricity. In the early 1880s he had started his company. In 1881, the Savoy Theatre in the City of Westminster, London was lit by Swan incandescent lightbulbs, which was the first theatre, and the first public building in the world, to be lit entirely by electricity.
When did Swan receive a patent for parchmentised thread?
The answer is the following: 1880


Input: Article: 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.

Now answer this question: Which form of music do Neapolitan mandolins feature? 

Output:
European classical music and traditional music.
