question:
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?
answer:
Peralta.

Passage: With the piece set to open on 26 December, Gilbert first read the libretto to the cast on 14 December, but Toole, who was playing the central role of Thespis, did not return from a tour of the British provinces until 18 December. He then appeared in nine performances at the Gaiety in the six days immediately after his return, and other actors had similar commitments. In addition, Hollingshead had committed the company to perform a pantomime at The Crystal Palace on 21 December, which included many of the performers who would be in Thespis. Lastly, Thespis was to play as the afterpiece to an H. J. Byron comedy, Dearer than Life, which shared many of its actors, including Toole and Fred Sullivan, and had to be rehearsed at the same time.Despite the short time available for rehearsals, Sullivan recalled that Gilbert insisted that the chorus play a major role, as it would do in their later Savoy operas:
Until Gilbert took the matter in hand choruses were dummy concerns, and were practically nothing more than a part of the stage setting. It was in 'Thespis' that Gilbert began to carry out his expressed determination to get the chorus to play its proper part in the performance. At this moment it seems difficult to realise that the idea of the chorus being anything more than a sort of stage audience was, at that time, a tremendous novelty. In consequence of this innovation, some of the incidents at the rehearsal of 'Thespis' were rather amusing. I remember that, on one occasion, one of the principals became quite indignant and said, 'Really, Mr. Gilbert, why should I stand here? I am not a chorus-girl!' to which Gilbert replied curtly, 'No, madam, your voice is not strong enough, or no doubt you would be.'. 
Question: What is the last name of the person who had an expressed determination to get the chorus to play its proper part in the performance?
answer:
Gilbert.
