Input: Consider Input: Karlheinz Brandenburg used a CD recording of Suzanne Vega's song "Tom's Diner" to assess and refine the MP3 compression algorithm. This song was chosen because of its nearly monophonic nature and wide spectral content, making it easier to hear imperfections in the compression format during playbacks. Some refer to Suzanne Vega as "The mother of MP3". This particular track has an interesting property in that the two channels are almost, but not completely, the same, leading to a case where Binaural Masking Level Depression causes spatial unmasking of noise artifacts unless the encoder properly recognizes the situation and applies corrections similar to those detailed in the MPEG-2 AAC psychoacoustic model. Some more critical audio excerpts (glockenspiel, triangle, accordion, etc.) were taken from the EBU V3/SQAM reference compact disc and have been used by professional sound engineers to assess the subjective quality of the MPEG Audio formats.

Output: What type of recording did Brandenburg use?


Input: Consider Input: The crisis deepened during the 17th century with the expulsion in 1609 of the Jews and the Moriscos, descendants of the Muslim population that converted to Christianity under threat of exile from Ferdinand and Isabella in 1502. From 1609 through 1614, the Spanish government systematically forced Moriscos to leave the kingdom for Muslim North Africa. They were concentrated in the former Kingdom of Aragon, where they constituted a fifth of the population, and the Valencia area specifically, where they were roughly a third of the total population. The expulsion caused the financial ruin of some of the nobility and the bankruptcy of the Taula de Canvi in 1613. The Crown endeavoured to compensate the nobles, who had lost much of their agricultural labour force; this harmed the economy of the city for generations to come. Later, during the so-called Catalan Revolt (1640–1652), Valencia contributed to the cause of Philip IV with militias and money, resulting in a period of further economic hardship exacerbated by the arrival of troops from other parts of Spain.

Output: What people group was descended from Muslim converts to Christianity?


Input: Consider Input: Others, such as Rep. Roger Sherman of Connecticut, believed the clause was unnecessary because the original Constitution only gave Congress stated powers, which did not include establishing a national religion. Anti-Federalists such as Rep. Thomas Tucker of South Carolina moved to strike the establishment clause completely because it could preempt the religious clauses in the state constitutions. However, the Anti-Federalists were unsuccessful in persuading the House of Representatives to drop the clause from the first amendment.


Output: Where was Representative Roger Sherman from?
