Q: Extract the answer to the question from the following context. Question: What did Tom's Diner offer? Context: 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.
A: making it easier to hear imperfections in the compression format during playbacks

Q: Extract the answer to the question from the following context. Question: What is a peculiar name for one of the cities? Context: Homer uses the terms Achaeans and Danaans (Δαναοί) as a generic term for Greeks in Iliad, and they were probably a part of the Mycenean civilization. The names Achaioi and Danaoi seem to be pre-Dorian belonging to the people who were overthrown. They were forced to the region that later bore the name Achaea after the Dorian invasion. In the 5th century BC, they were redefined as contemporary speakers of Aeolic Greek which was spoken mainly in Thessaly, Boeotia and Lesbos. There are many controversial theories on the origin of the Achaeans. According to one view, the Achaeans were one of the fair-headed tribes of upper Europe, who pressed down over the Alps during the early Iron age (1300 BC) to southern Europe. Another theory suggests that the Peloponnesian Dorians were the Achaeans. These theories are rejected by other scholars who, based on linguistic criteria, suggest that the Achaeans were mainland pre-Dorian Greeks. There is also the theory that there was an Achaean ethnos that migrated from Asia minor to lower Thessaly prior to 2000 BC. Some Hittite texts mention a nation lying to the west called Ahhiyava or Ahhiya. Egyptian documents refer to Ekwesh, one of the groups of sea peoples who attached Egypt during the reign of Merneptah (1213-1203 BCE), who may have been Achaeans.
A: Lesbos
