Question: Question: "Which of the following people is not female: Taylor, Kim Kardashian, or West?" 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." Answer:
Answer: West

[Q]: Question: "What is something that pleases only the lower-tiered members of NPOs?" Context: "Resource mismanagement is a particular problem with NPOs because the employees are not accountable to anybody with a direct stake in the organization. For example, an employee may start a new program without disclosing its complete liabilities. The employee may be rewarded for improving the NPO's reputation, making other employees happy, and attracting new donors. Liabilities promised on the full faith and credit of the organization but not recorded anywhere constitute accounting fraud. But even indirect liabilities negatively affect the financial sustainability of the NPO, and the NPO will have financial problems unless strict controls are instated. Some commentators have also argued that receiving significant funding from large for-profit corporations can ultimately alter the NPO's functions." Answer:
****
[A]: an employee may start a new program without disclosing its complete liabilities. The employee may be rewarded for improving the NPO's reputation, making other employees happy, and attracting new donors

Problem: Given the question: Question: "What are the things that are necessary for this process to function?" 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." Answer:
++++++++++++++++++++++++++++++++
The answer is:
phase-detection circuits in the amplifiers
