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: According to Gould, Beatles for Sale, the Beatles' fourth studio LP, evidenced a growing conflict between the commercial pressures of their global success and their creative ambitions. They had intended the album, recorded between August and October 1964, to continue the format established by A Hard Day's Night which, unlike their first two LPs, contained only original songs. They had nearly exhausted their backlog of songs on the previous album, however, and given the challenges constant international touring posed to their songwriting efforts, Lennon admitted, "Material's becoming a hell of a problem". As a result, six covers from their extensive repertoire were chosen to complete the album. Released in early December, its eight original compositions stood out, demonstrating the growing maturity of the Lennon–McCartney songwriting partnership.In early 1965, following a dinner with Lennon, Harrison and their wives, Harrison's dentist John Riley secretly added LSD to their coffee. Lennon described the experience: "It was just terrifying, but it was fantastic. I was pretty stunned for a month or two." He and Harrison subsequently became regular users of the drug, joined by Starr on at least one occasion. Harrison's use of psychedelic drugs encouraged his path to meditation and Hinduism. He commented: "For me, it was like a flash. The first time I had acid, it just opened up something in my head that was inside of me, and I realized a lot of things. I didn't learn them because I already knew them, but that happened to be the key that opened the door to reveal them. From the moment I had that, I wanted to have it all the time – these thoughts about the yogis and the Himalayas, and Ravi's music." McCartney was initially reluctant to try it, but eventually did so in late 1966. He became the first Beatle to discuss LSD publicly, declaring in a magazine interview that "it opened my eyes" and "made me a better, more honest, more tolerant member of society".
