Instructions: 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: Waters' lyrics to Wish You Were Here's "Have a Cigar" deal with a perceived lack of sincerity on the part of music industry representatives. The song illustrates a dysfunctional dynamic between the band and a record label executive who congratulates the group on their current sales success, implying that they are on the same team while revealing that he erroneously believes "Pink" is the name of one of the band members. According to author David Detmer, the album's lyrics deal with the "dehumanising aspects of the world of commerce", a situation the artist must endure to reach their audience.Absence as a lyrical theme is common in the music of Pink Floyd. Examples include the absence of Barrett after 1968, and that of Waters' father, who died during the Second World War. Waters' lyrics also explored unrealised political goals and unsuccessful endeavours. Their film score, Obscured by Clouds, dealt with the loss of youthful exuberance that sometimes comes with ageing. Longtime Pink Floyd album cover designer, Storm Thorgerson, described the lyrics of Wish You Were Here: "The idea of presence withheld, of the ways that people pretend to be present while their minds are really elsewhere, and the devices and motivations employed psychologically by people to suppress the full force of their presence, eventually boiled down to a single theme, absence: The absence of a person, the absence of a feeling." Waters commented: "it's about none of us really being there ... [it] should have been called Wish We Were Here".O'Neill Surber explored the lyrics of Pink Floyd and declared the issue of non-being a common theme in their music. Waters invoked non-being or non-existence in The Wall, with the lyrics to "Comfortably Numb": "I caught a fleeting glimpse, out of the corner of my eye. I turned to look, but it was gone, I cannot put my finger on it now, the child is grown, the dream is gone." Barrett referred to non-being in his final contribution to the band's catalogue, "Jugband Blues": "I'm most obliged to you for making it clear that I'm not here.".
Output:
What is the name of the song written by the man who lost a father in World War 2 that invoked non-being in the album "The Wall"?
