Definition: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: Def Jam's distributor, Columbia Records, refused to distribute the album due to the song "Angel of Death", because of its setting and description of the Holocaust. Reign in Blood was eventually distributed by Geffen Records; however, due to the controversy it did not appear on Geffen's release schedule.For the album, Slayer decided to abandon much of the earlier Satanic themes explored on their previous album Hell Awaits, and write about issues that were more on a street level. Reign in Blood's lyrics include death, anti-religion, insanity, and murderering, while the lead track "Angel of Death" details human experiments conducted at the Auschwitz concentration camp by Josef Mengele, who was dubbed "the Angel of death" by inmates. The song led to accusations of Nazi sympathizing and racism, which have followed the band throughout their career.Hanneman was inspired to write "Angel of Death" after he read a number of books on Mengele during a Slayer tour. Hanneman has complained people usually misinterpret the lyrics, and clarified: "Nothing I put in the lyrics that says necessarily he was a bad man, because to me — well, isn't that obvious? I shouldn't have to tell you that." The band utilized the controversy to attract publicity, incorporating the Reichsadler into their logo (also the S in the band's name resembles the Sig runes used by the SS), and writing a song in Divine Intervention titled "SS-3", which mentions Reinhard Heydrich, the second in command in the Schutzstaffel.
Output:
What was the name of the writer of Angel of Death?
