Problem: Extract the answer to the question from the following context. Question: Why are quadraphonic records named as such? Context: The development of quadraphonic records was announced in 1971. These recorded four separate sound signals. This was achieved on the two stereo channels by electronic matrixing, where the additional channels were combined into the main signal. When the records were played, phase-detection circuits in the amplifiers were able to decode the signals into four separate channels. There were two main systems of matrixed quadraphonic records produced, confusingly named SQ (by CBS) and QS (by Sansui). They proved commercially unsuccessful, but were an important precursor to later surround-sound systems, as seen in SACD and home cinema today.

A: four separate sound signals

Problem: Extract the answer to the question from the following context. Question: What are the origins of Drama? Context: Greek drama exemplifies the earliest form of drama of which we have substantial knowledge. Tragedy, as a dramatic genre, developed as a performance associated with religious and civic festivals, typically enacting or developing upon well-known historical or mythological themes. Tragedies generally presented very serious themes. With the advent of newer technologies, scripts written for non-stage media have been added to this form. War of the Worlds (radio) in 1938 saw the advent of literature written for radio broadcast, and many works of Drama have been adapted for film or television. Conversely, television, film, and radio literature have been adapted to printed or electronic media.

Problem: Extract the answer to the question from the following context. Question: What did West claim was widely misunderstood and not taken in the right context? Context: In September 2010, West wrote a series of apologetic tweets addressed to Swift including "Beyonce didn't need that. MTV didn't need that and Taylor and her family friends and fans definitely didn't want or need that" and concluding with "I'm sorry Taylor." He also revealed he had written a song for Swift and if she did not accept the song, he would perform it himself. However, on November 8, 2010, in an interview with a Minnesota radio station, he seemed to recant his past apologies by attempting to describe the act at the 2009 awards show as "selfless" and downgrade the perception of disrespect it created. In "Famous," a track from his 2016 album The Life of Pablo, West implies that this incident led to Swift's stardom, rapping, "I feel like me and Taylor might still have sex/ Why? I made that bitch famous." After some media backlash about the reference, West posted on Twitter "I did not diss Taylor Swift and I've never dissed her...First thing is I'm an artist and as an artist I will express how I feel with no censorship." He continued by adding that he had asked both Swift and his wife, Kim Kardashian, for permission to publish the line.

A:
downgrade the perception of disrespect it created
