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.

Passage: A woman's dead body is shown in a cluster of lantana bushes. 
Leon, a police officer, and Jane, have sex in a motel room. They part ways, and Leon and his wife, Sonja, attend Latin dance classes that the recently separated Jane is also taking.
Leon does not enjoy the classes. He is seen savagely beating a drug dealer during a bust. He has emotional issues but refuses to confront or admit to them. Sonja sees a therapist, Valerie, who has just published a book on her own daughter's murder 18 months ago. She and her husband, John, are barely on speaking terms; he later refers to their marriage as held together by their grief. She feels threatened by another patient, Patrick Phelan, who is having an affair with a married man, which forces Valerie to confront her own issues in her marriage to John.
Hoping to see Leon again, Jane purposely bumps into him outside the police station, and they have sex again despite Leon's reservations. Nik is upset that she is seeing someone because he is friends with her estranged husband, Pete, who wants to return home. Jane pairs up with Sonja in the next salsa class, which angers Leon, who ends their arrangement, which upsets Jane. She invites Nik over for coffee at the behest of Paula, with whom she is friendly and offers him money as they are struggling. Paula now starts to dislike Jane.
Valerie is coming home late one night and drives off the road. She is stranded and makes several calls to John, who does not answer. Finally, she is seen approaching a car coming along the road but never makes it home. Leon is the investigating detective on the case and looks into her office and notes.  Surprised at seeing his wife's name and file, he takes an audio recording of their sessions.
Whose disappearance is Leon investigating when he finds tapes of his wife's therapy sessions?

Passage: Martin recalled that Sgt. Pepper "grew naturally out of Revolver", marking "an era of almost continuous technological experimentation". According to Geoff Emerick, the Beatles' recording engineer, the "major difference" between the two albums was that, with Sgt. Pepper, there was no absolute deadline for completion. Sessions began on 24 November 1966 in Studio Two at EMI Studios (subsequently Abbey Road Studios), marking the first time that the Beatles had come together since September. Afforded the luxury of a nearly limitless recording budget, the band booked open-ended sessions that started at 7 pm and allowed them to work as late as they wanted. They began with "Strawberry Fields Forever", followed by two other songs that were thematically linked to their childhoods: "When I'm Sixty-Four", the first session for which took place on 6 December, and "Penny Lane". "Strawberry Fields Forever" made prominent use of Mellotron, a keyboard instrument on which the keys triggered tape-recordings of a variety of instruments, enabling its user to play keyboard parts using those voices."Strawberry Fields Forever" and "Penny Lane" were subsequently released as a double A-side in February 1967 after EMI and Epstein pressured Martin for a single. When it failed to reach number one in the UK, British press agencies speculated that the group's run of success might have ended, with headlines such as "Beatles Fail to Reach the Top", "First Time in Four Years" and "Has the Bubble Burst?" In keeping with the band's approach to their previously issued singles, the songs were then excluded from Sgt. Pepper. Martin later described the decision to drop these two songs as "the biggest mistake of my professional life". In his judgment, "Strawberry Fields Forever", which he and the band spent an unprecedented 55 hours of studio time recording, "set the agenda for the whole album". He explained: "It was going to be a record ... [with songs that] couldn't be performed live: they were designed to be studio productions and that was the difference." McCartney declared: "Now our performance is that record.".
What is the name of the band that began Sgt. Pepper with "Strawberry Fields Forever," followed by two other songs that were thematically linked to their childhoods?

Passage: Impresario and author John Hollingshead, the lessee of London's Gaiety Theatre since 1868, had produced a number of successful musical burlesques and operettas there. Indeed, Hollingshead "boasted that he kept alight 'the sacred lamp of burlesque.'" Gilbert and Sullivan were each well acquainted with the Gaiety and its house artistes.  Gilbert's Robert the Devil (a burlesque of the opera Robert le Diable) had been on the programme on the theatre's opening night on 21 December 1868, with Nellie Farren in the title role, and played successfully for over 100 nights. Constance Loseby and Annie Tremaine (both of whom had roles in Thespis) were also in the cast of Robert, and Arthur Sullivan was in the audience on that opening night as one of Hollingshead's guests. It was a great success, "received with a storm of approbation". Less successfully, Gilbert had also written a play for the theatre in 1869 called An Old Score. Hollingshead would later say that the piece was "too true to nature". By late September or early October 1871, Gaiety programmes announced that "The Christmas Operatic Extravaganza will be written by W. S. Gilbert, with original music by Arthur Sullivan." There would be prominent roles for the popular comedian J. L. Toole, as well as Farren, the theatre's star "principal boy" in all of its burlesques.
How and when the pair came to collaborate on Thespis is uncertain. Gilbert was a logical choice for the assignment. With seven operas and plays premièring that year and over a dozen other burlesques, farces and extravaganzas under his belt, he was well known to London theatregoers as a comic dramatist. Sullivan, however, was at this point mainly known for his serious music. His completed music that year included the choral cantata On Shore and Sea, a suite of incidental music for Shakespeare's The Merchant of Venice, and numerous hymns, including "Onward, Christian Soldiers". He did have two comic operas to his credit, Cox and Box (1866) and The Contrabandista (1867), but the latter was four years in the past and had been unsuccessful. In September 1871, Sullivan had been engaged to conduct at The Royal National Opera, but it failed abruptly, leaving him unexpectedly without commitments. Hollingshead's offer of a role to his brother, Fred Sullivan, may have encouraged him to write the music for Thespis.The production "aroused a great deal of interest and speculation". Ironically, it had "probably the largest audience" of any Gilbert and Sullivan première, as the Gaiety was the largest of the five London theatres at which their joint works premièred.
What was the name of the unsuccessful comic opera by the man mainly known for his serious music?
