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?

Ex Output:
Hoolihan.

Passage: Carmen (French pronunciation: [kamn]; Spanish: [kamen]) is an opera in four acts by French composer Georges Bizet. The libretto was written by Henri Meilhac and Ludovic Halevy, based on a novella of the same title by Prosper Merimee. The opera was first performed by the Opera-Comique in Paris on 3 March 1875, where its breaking of conventions shocked and scandalized its first audiences.
Bizet died suddenly after the 33rd performance, unaware that the work would achieve international acclaim within the following ten years. Carmen has since become one of the most popular and frequently performed operas in the classical canon; the "Habanera" from act 1 and the "Toreador Song" from act 2 are among the best known of all operatic arias.
The opera is written in the genre of opera comique with musical numbers separated by dialogue. It is set in southern Spain and tells the story of the downfall of Don Jose, a naive soldier who is seduced by the wiles of the fiery gypsy Carmen. Jose abandons his childhood sweetheart and deserts from his military duties, yet loses Carmen's love to the glamorous torero Escamillo, after which Jose kills her in a jealous rage. The depictions of proletarian life, immorality, and lawlessness, and the tragic death of the main character on stage, broke new ground in French opera and were highly controversial.
After the premiere, most reviews were critical, and the French public was generally indifferent. Carmen initially gained its reputation through a series of productions outside France, and was not revived in Paris until 1883. Thereafter, it rapidly acquired popularity at home and abroad. Later commentators have asserted that Carmen forms the bridge between the tradition of opera comique and the realism or verismo that characterised late 19th-century Italian opera.
The music of Carmen has since been widely acclaimed for brilliance of melody, harmony, atmosphere, and orchestration, and for the skill with which Bizet musically represented the emotions and suffering of his characters. After the composer's death, the score was subject to significant amendment, including the introduction of recitative in place of the original dialogue; there is no standard edition of the opera, and different views exist as to what versions best express Bizet's intentions. The opera has been recorded many times since the first acoustical recording in 1908, and the story has been the subject of many screen and stage adaptations.
Question: What year was the first acoustical recording of the opera that has been widely acclaimed for brilliance of melody?

Ex Output:
1908.

Passage: Superstitious New York gambler Joe Baldwin, owner of the thoroughbred racing horse Sarcasm, believes that luck can be bought with charitable deeds. Before the Kentucky Derby, to "buy luck," he finances an expensive trip to Europe for gold-digger Jean Jason, his "good luck charm," not knowing she is taking her lover with her, gigolo and sometime artist Paul Vinette. He also gives his old friend Frank Brent cash to save his cab business and visits an orphanage in Louisville with his sister, where he meets Betty McKay, a pretty teacher who scoffs at his philosophy.
She scolds him for wishing for rain on the day of the Derby to aid his horse, who runs best on a muddy track, because the orphans plan an outdoor party. Although it rains as wished, Sarcasm loses the Derby, and Joe is convinced that it was because the orphans were pulling against him. In an attempt to repair the damage before the Preakness, Joe throws the orphans a lavish party, hiring clowns and other entertainment. To Betty's surprise, Joe is as excited as the children, and they fall in love.
After Sarcasm wins the Preakness, Joe returns to New York, where Jean is back from Europe. Joe tells her that he will not be seeing her any more because he is going to marry Betty, and she cajoles $50,000 from him as a final "luck insurance" payment. Before Joe shows up with the check, however, Paul arrives at Jean's apartment. They argue when he sees that she plans to run out on him with the money. Jean threatens him with a gun, and during a scuffle, kills her.
Question: What is the name of the horse that runs the best on a muddy track?

Ex Output:
Sarcasm.
