Passage: Josephine-Eleonore-Marie-Pauline de Galard de Brassac de Bearn (18251860) married Albert de Broglie on 18 June 1845, and they had five sons together. Although not high royalty, on the occasion of their marriage, they styled themselves Prince and Princesse respectively. Pauline was a highly intelligent and religious woman, who was well read and wrote a number of texts in her lifetime. Her shyness was well known; she was widely considered strikingly beautiful and charming, but those around her would often avoid eye contact so as not to embarrass her. Albert was devoted to his wife, and commissioned the painting after being impressed by Ingres' 1845 portrait of his sister, the Comtesse d'Haussonville.
Albert approached Ingres around 1850 to undertake the portrait. Ingres dined with the de Broglie family in January 1850, and according to one eye witness, "seemed to be very happy with his model."Although Ingres' main source of income came from portraiture, it distracted from his main interest in history painting, which early in his career, was far less lucrative. He found acclaim in the 1840s, when he became successful enough to no longer depend on commissions. This painting was Ingres' second-last female portrait, and final society portrait.Influenced by the working methods of Jacques-Louis David, Ingres began with a number of nude preparatory sketches, for which he employed professional models. He built up a picture of the sitter's underlying anatomical structure, as seen in the Musee Bonnat study, before deciding on how to build the lavish costume and accessories. Although there is no surviving record of the commissions, and the exact sequence of events is uncertain, the sketches can be dated from 1850, the year the style of her evening dress came into fashion. Ingres signed and dated the final picture at the left center "J. INGRES. pit 1853".Pauline died in 1860 aged 35 from tuberculosis. After her death, Albert published three volumes of her essays on religious history. Albert (who in 1873 became the 28th Prime Minister of France) lived until 1901, but was heartbroken and did not remarry. He kept her portrait for the remainder of his life draped in fabric and hidden behind a velvet curtain, only lending it to select exhibitions. After his own death, the painting passed within the family until 1958 when it was sold to the Metropolitan Museum of Art via the banker and art collector Robert Lehman, and is today held in the Lehman Wing. The family kept most of the jewelry and accessories seen in the painting, although the marabou feathers were sold to the Costume Institute of the Metropolitan Museum.
Question: What is the full name of the person who bought the portrait of the wife of the man who was heartbroken and did not remarry?
Robert Lehman.

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?
Hoolihan.

Passage: Following the release of The Final Cut, Waters embarked on a solo career. In 1984, he released his first solo album, The Pros and Cons of Hitch Hiking, a project about a man's dreams across one night that dealt with Waters' feelings about monogamy and family life versus "the call of the wild". In the end the character, Reg, chooses love and matrimony over promiscuity. The album featured guitarist Eric Clapton, jazz saxophonist David Sanborn, and artwork by Gerald Scarfe. Kurt Loder described The Pros And Cons of Hitch Hiking as a "strangely static, faintly hideous record". Rolling Stone rated the album a "rock bottom one star". Years later, Mike DeGagne of AllMusic praised the album for its "ingenious symbolism" and "brilliant use of stream of consciousness within a subconscious realm", rating it four out of five stars.Waters began touring in support of the album, aided by Clapton, a new band, new material, and a selection of Pink Floyd favourites. Waters debuted his tour in Stockholm on 16 June 1984. The tour suffered from poor ticket sales and some performances at larger venues were cancelled; Waters estimated that he lost 400,000 on the tour. In March 1985, Waters went to North America to play smaller venues with the Pros and Cons Plus Some Old Pink Floyd StuffNorth America Tour 1985. The Pros and Cons of Hitch Hiking has been certified Gold by the RIAA.In 1986, Waters contributed songs and a score to the soundtrack of the animated movie When the Wind Blows, based on the Raymond Briggs book of the same name. His backing band featuring Paul Carrack was credited as The Bleeding Heart Band. In 1987, Waters released Radio K.A.O.S., a concept album based on a mute man named Billy from an impoverished Welsh mining town who has the ability to physically tune into radio waves in his head. Billy first learns to communicate with a radio DJ, and eventually to control the world's computers. Angry at the state of the world in which he lives, he simulates a nuclear attack. Waters followed the release with a supporting tour also in 1987.
Question: What is the name of the mute man in the concept album released by the person who began a solo career in 1984?
Billy.
