Problem: Given the question: The answer to the question: Who does the doctor brought in to help with the case fall in love with? is inside the article: 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., can you guess it ?

Problem: Given the question: The answer to the question: What was the name of the song that replaced Simmonds' song in 2006? is inside the article: SVT selects performers for the entries. Artists who perform the demo of a song automatically enter the competition; they must perform their songs if suitable alternate performers cannot be found. The artists' songs risk disqualification if they refuse. In the past, this rule led to the disqualification of, among others, Carola's "Nar loven faller" in 2003 and Stephen Simmonds's "So Good" in 2006. SVT may also give songs to other performers without considering the interests of the demo artist. This prevented the Brandsta City Slackers (in 2004) and Pernilla Wahlgren (in 2005) from performing the songs they had submitted. Replacements for disqualified songs fare unpredictably at the competition. In 2006, "Naughty Boy" by Hannah Graaf (the replacement for Simmonds' song) finished second to last in its semi-final. In 2002 and 2007, by contrast, the replacements performed by Jan Johansen and Mans Zelmerlow reached the final ten. The contestants that will perform the twenty-eight qualifiers from the preselection are announced in late November. Singer-songwriters are common. As such, artists often confirm that they will participate before the official announcement. The wildcard (joker) system was introduced in 2004 to diversify the music featured. Four artists, one in each semi-final, were invited by SVT to enter a song of their choice into the competition, provided it does not breach the rules. The wildcard songs and artists were announced in January. Since the wildcards' introduction, three have won the competition. In 2011 there were 15 wildcards. The wildcard system was discontinued in 2013., can you guess it ?

Problem: Given the question: The answer to the question: Who does the factory worker drive out of town? is inside the article: When passed over for promotion at work in favor of a foreign-born friend, Frank Taylor, a midwestern factory worker, joins the anti-immigrant Black Legion, a secret white vigilante organization portrayed as related to the Ku Klux Klan. Dressed in black robes and hoods, Taylor and the Legion mount a torchlight raid and burn down the friend's chicken farm, driving him out of town, so that Taylor can gain the job he believed was his. Soon, however, Taylor's recruiting activities with the Legion get in the way of his work, and he is demoted in favor of his Irish neighbor Mike Grogan. The Legion takes action again, attacking Grogan. Under the continued influence of the Legion, Taylor becomes a brutal racist, and alienates his wife. He starts drinking heavily and takes up with a loose woman. When his friend Ed Jackson tries to counsel him, a drunken Taylor tells about his Legion activities. Taylor reports the conversation to Cliff, a co-worker and fellow member of the Legion, who initiates a false rumor that Jackson is a woman-beater. On the pretext of punishing him for that offense, the Legion kidnaps Jackson, planning to flog him. Jackson tries to escape. As he is running away, Taylor shoots and kills him; breaking down afterward with guilt and remorse, he exclaims, "I didn't mean to shoot!"Taylor is arrested for the murder, and the Legion threatens his wife and son to prevent him from implicating the secret group in the crime. Taylor finally tells the truth, resulting in all the members of the Black Legion being convicted of murder and sentenced to life in prison., can you guess it ?
