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: During the spring of 1990, Anjali Dutt was hired to replace Moulder, who had left to work with the bands Shakespears Sister and Ride. Dutt assisted in the recording of vocals and several guitar tracks. During this period, the band recorded in various studios, often spending a single day at a studio before deciding it was unsuitable. In May 1990, My Bloody Valentine settled on Protocol in Holloway as their primary location, and work began in earnest on the album, as well as a second EP titled Tremolo. Like Glider, Tremolo contained a song—"To Here Knows When"—that later appeared on Loveless. The band stopped recording during the summer of 1990 to tour in support of the release of Glider. When Moulder returned to the project in August, he was surprised by how little work had been completed. By that point, Creation was concerned by how much the album was costing. Moulder left again in March 1991 to work for the the Jesus and Mary Chain. In an interview with Select, Shields explained the stop-start nature of his recording, using "When You Sleep" as an example:We recorded the drums in September '89. The guitar was done in December. The bass was done in April. 1990 we're in, now. Then nothing happens for a year really." So it doesn't have vocals at this stage? "No." Does it have words? "No." Does it even have a title? "No. It has a song number. 'Song 12' it was called. And… I'm trying to remember… the melody line was done in '91. The vocals were '91. There were huge gaps though. Months and months of not touching songs. Years. I used to forget what tunings I'd used.
Output:
What band had Moulder left?
