Passage: Dr. Frank Peralta is stabbed to death in his apartment one night. The detective on the case, Lt. Stevenson, quickly finds multiple witnesses putting Peralta's lover, Terry Collins, at the scene. However, when Stevenson finds Terry and questions her, she has an iron-clad alibi with multiple witnesses. It is revealed that Terry has an identical twin sister, Ruth, and the pair share the same job and routinely switch places for their own benefit. Stevenson and the district attorney are unable to prosecute, since the twins refuse to confirm which one of them has the alibi.
Unable to accept the "perfect crime", Lt. Stevenson asks Dr. Scott Elliot for help. Scott is an expert on twin study, and has been routinely encountering the Collins twins at their shared place of work, but does not know which one is which. As a front, Scott asks Terry and Ruth if he can study both of them individually as part of his research. The twins accept, though Ruth is worried that Scott might find out that Terry was at Peralta's apartment the night of the murder. However, Terry is attracted to Scott and insists that they can keep the secret for the sake of seeing him. She also comforts Ruth, reminding her that she was only at Peralta's apartment but didn't kill him.
From Scott's psychological tests and by spending time with them, he discovers that Ruth is kind and loving, while Terry is highly intelligent, insane, and has been manipulating Ruth almost their entire lives. Terry is jealous that people keep preferring Ruth over her, and is again enraged when Scott falls in love with Ruth instead of her. Terry starts methodically gaslighting Ruth, making her believe that she's hallucinating and going insane, in the hopes of pushing her to suicide. 
Question: What is the last name of the person whose murder the insane woman is suspected of committing?

Ex Output:
Peralta.

Passage: An unknown sniper positions himself at the Los Angeles Memorial Coliseum prior to a professional football championship dubbed as "Championship X" (Ten) between Baltimore and Los Angeles  similar to the Super Bowl. He is spotted by a Goodyear Blimp camera. Police and SWAT team are immediately called in by the stadium manager Sam McKeever.
Police Captain Peter Holly, working with SWAT team Sergeant Chris Button, devises a plan to capture the sniper before the conclusion of the game.
Many of the fans attending the game are introduced. They include Steve and Janet (David Janssen and Gena Rowlands), an argumentative middle-aged couple; Stu Sandman, a gambling addict; a Catholic priest, who is a friend of quarterback Charlie Tyler; young married couple Mike and Peggy Ramsay (Beau Bridges and Pamela Bellwood); an elderly pickpocket and his young accomplice (Juli Bridges, the then-wife of Beau Bridges); and football fan Al, who begins flirting with Lucy when he notices her date is more interested in the game than in her.
The stadium's maintenance director, named Paul, discovers the sniper's presence and attempts to confront him. The sniper strikes Paul with the butt of his rifle, and, undetected by fans, causes Paul to fall several stories, leaving him severely injured. SWAT team members position themselves on stadium light towers to take aim on the sniper's nest.
Mike Ramsay spots the sniper with his binoculars. He reports it to the police, but rather than thank him, they question him suspiciously and then physically overpower him.
Shortly after the game's two-minute warning, the SWAT team is given the green light to go after the sniper. Seeing that he is surrounded, the sniper opens fire, shooting randomly into the crowd. His shots cause a massive riot in which the panicked fans spill onto the field. 
Question: What is the full name of the person who is questioned after reporting the location of the sniper to the police?

Ex Output:
Mike Ramsay.

Passage: In January 1980, Michael Stipe met Peter Buck in Wuxtry Records, the Athens record store where Buck worked. The pair discovered that they shared similar tastes in music, particularly in punk rock and protopunk artists like Patti Smith, Television, and the Velvet Underground. Stipe said, "It turns out that I was buying all the records that [Buck] was saving for himself." Through mutual friend Kathleen O'Brien, Stipe and Buck then met fellow University of Georgia students Mike Mills and Bill Berry, who had played music together since high school and lived together in Georgia. The quartet agreed to collaborate on several songs; Stipe later commented that "there was never any grand plan behind any of it". Their still-unnamed band spent a few months rehearsing in a deconsecrated Episcopal church in Athens, and played its first show on April 5, 1980, supporting The Side Effects at O'Brien's birthday party held in the same church, performing a mix of originals and 1960s and 1970s covers. After considering Twisted Kites, Cans of Piss, and Negro Eyes, the band settled on "R.E.M." (which is an acronym for rapid eye movement, the dream stage of sleep), which Stipe selected at random from a dictionary.The band members eventually dropped out of school to focus on their developing group. They found a manager in Jefferson Holt, a record store clerk who was so impressed by an R.E.M. performance in his hometown of Chapel Hill, North Carolina, that he moved to Athens. R.E.M.'s success was almost immediate in Athens and surrounding areas; the band drew progressively larger crowds for shows, which caused some resentment in the Athens music scene. Over the next year and a half, R.E.M. toured throughout the Southern United States. Touring was arduous because a touring circuit for alternative rock bands did not then exist. The group toured in an old blue van driven by Holt, and lived on a food allowance of $2 each per day.During April 1981, R.E.M. recorded its first single, "Radio Free Europe", at producer Mitch Easter's Drive-In Studios in Winston-Salem, North Carolina. Initially distributing it as a four-track demo tape to clubs, record labels and magazines, the single was released in July 1981 on the local independent record label Hib-Tone with an initial pressing of 1,000 copies—600 of which were sent out as promotional copies. The single quickly sold out, and another 6,000 copies were pressed due to popular demand, despite the original pressing leaving off the record label's contact details. Despite its limited pressing, the single garnered critical acclaim, and was listed as one of the ten best singles of the year by The New York Times. 
Question: What are the full names of the four individuals in the quartet that agreed to collaborate on several songs?

Ex Output:

Michael Stipe.
