In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Example Input: Who is married to Kim?, 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.
Example Output: West

Example Input: What is a legal doctrine that obligates courts to follow historical cases when making a ruling on a similar case, Context: Federal law originates with the Constitution, which gives Congress the power to enact statutes for certain limited purposes like regulating interstate commerce. The United States Code is the official compilation and codification of the general and permanent federal statutes. Many statutes give executive branch agencies the power to create regulations, which are published in the Federal Register and codified into the Code of Federal Regulations. Regulations generally also carry the force of law under the Chevron doctrine. Many lawsuits turn on the meaning of a federal statute or regulation, and judicial interpretations of such meaning carry legal force under the principle of stare decisis.
Example Output: stare decisis
