Problem: Please answer a question about the following article about Mandolin:
The transition from the mandolino to the mandolin began around 1744 with the designing of the metal-string mandolin by the Vinaccia family, 3 brass strings and one of gut, using friction tuning pegs on a fingerboard that sat "flush" with the sound table. The mandolin grew in popularity over the next 60 years, in the streets where it was used by young men courting and by street musicians, and in the concert hall. After the Napoleonic Wars of 1815, however, its popularity began to fall. The 19th century produced some prominent players, including Bartolomeo Bortolazzi of Venice and Pietro Vimercati. However, professional virtuosity was in decline, and the mandolin music changed as the mandolin became a folk instrument; "the large repertoire of notated instrumental music for the mandolino and the mandoline was completely forgotten". The export market for mandolins from Italy dried up around 1815, and when Carmine de Laurentiis wrote a mandolin method in 1874, the Music World magazine wrote that the mandolin was "out of date." Salvador Leonardi mentioned this decline in his 1921 book, Methode pour Banjoline ou Mandoline-Banjo, saying that the mandolin had been declining in popularity from previous times.
Who were two of the promiment players in the 19th century?
A: Bartolomeo Bortolazzi of Venice and Pietro Vimercati

Problem: Please answer a question about the following article about Carnival:
A major feature is the calypso competition. Calypso music, originating in Trinidad, uses syncopated rhythm and topical lyrics. It offers a medium in which to satirise local politics, amidst the general bacchanal. Calypso tents, also originating in Trinidad, feature cadres of musicians who perform biting social commentaries, political exposes or rousing exhortations to "wuk dah waistline" and "roll dat bumper". The groups compete for the Calypso Monarch Award, while the air is redolent with the smells of Bajan cooking during the Bridgetown Market Street Fair. The Cohobblopot Festival blends dance, drama and music with the crowning of the King and Queen of costume bands. Every evening the "Pic-o-de-Crop" Show is performed after the King of Calypso is finally crowned. The climax of the festival is Kadooment Day celebrated with a national holiday when costume bands fill the streets with pulsating Barbadian rhythms and fireworks.
