PROBLEM: Passage: On Christmas Eve in 19th-century London, Fred is sliding on ice on a sidewalk. He meets Peter and Tim Cratchit, sons of his uncle Ebenezer's clerk, Bob Cratchit. When Fred reveals who he is, the boys take off in terror. Fred soon arrives at the counting-house of his miserly maternal uncle, Ebenezer Scrooge. After declining an invitation from his nephew to dine with him on Christmas, Scrooge rejects two gentlemen collecting money for charity. That night, Scrooge reluctantly allows his employee Bob Cratchit to have Christmas off with pay but orders him back all the earlier the day after. Later Bob accidentally knocks off Scrooge's hat with a snowball. Scrooge dismisses Bob and withholds a week's pay to compensate for his ruined hat, also demanding a shilling to make up the difference. Bob spends the last of his wages on food for his family's Christmas dinner. 
In his house, Scrooge is confronted by the ghost of his deceased business partner, Jacob Marley, who warns Scrooge to repent his wicked ways or he will be condemned in the afterlife as Marley was. He tells Scrooge he will be haunted by three spirits.
At one o'clock, Scrooge is visited by the youthful Ghost of Christmas Past, who takes him back in time to his early life. Scrooge is shown his unhappiness when he was left to spend the holidays alone at school, and his joy when his sister, Fran, came to take him home for Christmas. The spirit reminds Scrooge that Fran, dead for some years, is the mother of his nephew. Scrooge is shown his early career in business and money lending as an employee under Fezziwig. 
Question: Who explains that there will be three spirits?

SOLUTION: Jacob Marley.

PROBLEM: Passage: 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. 
Question: What is the last name of the person who talks about the marble?

SOLUTION: Hoolihan.

PROBLEM: Passage: While Raff was able to offer "practical suggestions [in orchestration] which were of great value to Liszt", there may have been "a basic misunderstanding" of the nature of their collaboration. Liszt wanted to learn more about instrumentation and acknowledged Raff's greater expertise in this area. Hence, he gave Raff piano sketches to orchestrate, just as he had done earlier with Conradi—"so that he might rehearse them, reflect on them, and then, as his confidence in the orchestra grew, change them." Raff disagreed, having the impression that Liszt wanted him on equal terms as a full collaborator. While attending an 1850 rehearsal of Prometheus, he told Bernhard Cossmann, who sat next to him, "Listen to the instrumentation. It is by me."Raff continued making such claims about his role in Liszt's compositional process. Some of these accounts, published posthumously by Die Musik in 1902 and 1903, suggest that he was an equal collaborator with Liszt. Raff's assertions were supported by Joachim, who had been active in Weimar at approximately the same time as Raff. Walker writes that Joachim later recalled to Raff's widow "that he had seen Raff 'produce full orchestral scores from piano sketches.'" Joachim also told Raff's biographer Andreas Moser that "the E-flat-major Piano Concerto was orchestrated from beginning to end by Raff." Raff's and Joachim's statements effectively questioned the authorship of Liszt's orchestral music, especially the symphonic poems. This speculation was debased when composer and Liszt scholar Peter Raabe carefully compared all sketches then known of Liszt's orchestral works with the published versions of the same works. Raabe demonstrated that, regardless of the position with first drafts, or of how much assistance Liszt may have received from Raff or Conradi at that point, every note of the final versions represents Liszt's intentions. 
Question: What is the last name of the person who gave piano sketches to orchestrate to Conradi?

SOLUTION:
Liszt.
