Question: The answer to the question: What is the last name of the person who buys a jar of moisturizing cream? is inside the article: Detective Mike Hoolihan is investigating the murder of Jennifer Rockwell, an astrophysicist at an observatory in New Orleans. She had presented a talk on black holes in the evening, but was found dead in the morning by the manager of the observatory. She had been shot in the face, but there was no weapon. There is a sock and a jar of moisturizing cream found at the scene. The manager claims that he was out all night with an associate. The sock is traced to Jennifer's boyfriend, who claims he left hurriedly to work on a new theory. Jennifer's home is full of tchotchkes and other old nick-nacks. Mike passes out when she picks up a Florida snow globe, and imagines unique blue marbles similar to one that is on a string around her neck. When she comes to, she talks about the marble, and how she doesn't remember where it came from. She was an orphan, and has always had it. Her co-investigator and supervisor suggest that this looks like "The .38 Caliber Killer", who killed young women, but hadn't struck in many years. The murderer always exchanged nick nacks with his victims. While doing a more detailed search of the area, Mike finds a gun in a case, and a red scarf she had been having dreams about. The gun, a .38 revolver, is traced to the observatory manager, who admits he found it, and tried to dispose of it so he wouldn't be a suspect. Figuring from where the gun originally lay, Mike concludes that Jennifer had shot herself. The investigators agree. In photos of the crime scene, Mike realizes that there are no photos of the jar of moisturizing cream that she noted. When she buys a jar of the cream, she reacts as if memories come flooding back., can you guess it ?
Answer: Hoolihan

Question: The answer to the question: What is the full name of the person who has a miscarriage? is inside the article: A happy vacation along California's rocky coast for a pregnant Mandy Anthony, her husband Dick           (Arthur Franz) and her sister Kate Hazelton is ruined when Mandy has a seizure, loses consciousness and miscarries. Worse, when she awakens, she says that she is "Felicia" and calls Dick "Dickens." A stunned Dick tells an uncomprehending Kate that Felicia was his first wife and Dickens was her pet name for him - and that he's never told Mandy of his first marriage, Dickens or Felicia's death six years earlier! Felicia demands to visit the Bradleys, an elderly couple whom Dick says that Mandy doesn't know. They're Felicia's parents. She convinces them that she is indeed Felicia, back from the dead. Mrs. Bradley is delighted; Mr. Bradley is horrified. Dick, upset by the reunion, tells Kate that Mrs. Bradley "was a strange, evil woman - Felicia, too" and that he was a fool to not face the truth. Meanwhile, Mr. Bradley says to Mrs. Bradley, "God will punish you for this." Mrs. Bradley contemptuously replies, "You believe in your god. I'll believe in mine." Dick invites his friends John Mitchell and Molly Prentiss to the vacation house for cocktails. Afterwards, Felicia tries to gas Kate in her bedroom - Kate survives when Mandy's voice awakens her - then goes outside and kills their dog, Copper, who loved Mandy but hates Felicia. The next day, Kate is at John's house when neighbor Nancy Cordell drops by. She casually tells Kate that she and the Bradleys are members of Maître Renault's (Otto Reichow) devil cult, as was Felicia. Kate expresses an interest and Nancy arranges for Kate to meet Renault., can you guess it ?

Question: The answer to the question: What system pairs the eight songs off against each other? is inside the article: Prior to the introduction of the current format of semifinals (deltävlingar) in 2002, the competition was usually a single live show. Under the current system, four semifinals are broadcast at 20:00 CET on consecutive Saturday nights. The semi-finals begin in early February, and seven songs compete in each show. Unlike in the final, no juries are used; televoting decides the results. The songs are performed live with telephone lines open for the first round of voting; two songs with the fewest votes do not qualify to the second round. The top five battle for a place in the final and Andra chansen round – the 1st and 2nd placed songs qualifying to the final, and the 3rd and 4th placed songs progressing to Andra chansen. Both finalists reprise their entries at the end of the broadcast. The organisation of a semi-final system for Melodifestivalen popularised televised heats at national Eurovision selections. A similar system was adopted by the Eurovision itself in 2004. The Second Chance round (Andra chansen) is the fifth heat in which the remaining four entries to the final are chosen. The third- and fourth-placed songs from each semi-final (eight songs in total) compete in the event. The first Second Chance round in 2002 had a panel of former winners decide the two finalists. Between 2003 and 2006, the semi-final performances were re-broadcast, and a round of voting narrowed the songs to three or four. Another round then determined the two finalists. The programme was broadcast on the Sunday afternoon after the fourth semi-final. It was held in a smaller venue than those that would have hosted the semi-finals—such as Berns Salonger in Stockholm, which hosted the Second Chance round in 2005. In 2007, the Second Chance round became a full semi-final, taking place in a venue comparable in size to those hosting the others. The expanded Second Chance takes place on a Saturday night, adding an extra week to the event's timetable. The format of voting also changed with the introduction of a knock-out system. The..., can you guess it ?
Answer:
a knock-out system
