Question: Passage: The building was sold in 1549 by Buonaccorso Pitti, a descendant of Luca Pitti, to Eleonora di Toledo.  Raised at the luxurious court of Naples, Eleonora was the wife of Cosimo I de' Medici of Tuscany, later the Grand Duke.  On moving into the palace, Cosimo had Vasari enlarge the structure to fit his tastes; the palace was more than doubled by the addition of a new block along the rear.  Vasari also built the Vasari Corridor, an above-ground walkway from Cosimo's old palace and the seat of government, the Palazzo Vecchio, through the Uffizi, above the Ponte Vecchio to the Palazzo Pitti. This enabled the Grand Duke and his family to move easily and safely from their official residence to the Palazzo Pitti. Initially the Palazzo Pitti was used mostly for lodging official guests and for occasional functions of the court, while the Medicis' principal residence remained the Palazzo Vecchio. It was not until the reign of Eleonora's son Francesco I and his wife Johanna of Austria that the palazzo was occupied on a permanent basis and became home to the Medicis' art collection.Land on the Boboli hill at the rear of the palazzo was acquired in order to create a large formal park and gardens, today known as the Boboli Gardens. The landscape architect employed for this was the Medici court artist Niccolò Tribolo, who died the following year; he was quickly succeeded by Bartolommeo Ammanati. The original design of the gardens centred on an amphitheatre, behind the corps de logis of the palazzo. The first play recorded as performed there was Andria by Terence in 1476. It was followed by many classically inspired plays of Florentine playwrights such as Giovan Battista Cini. Performed for the amusement of the cultivated Medici court, they featured elaborate sets designed by the court architect Baldassarre Lanci. 
Question: What is the first name of the Grand Duke whose family was enabled to move easily and safely from their official residence?

Answer: Cosimo.


Question: Passage: Zappa's relationship with long-time manager Herb Cohen ended in 1976. Zappa sued Cohen for skimming more than he was allocated from DiscReet Records, as well as for signing acts of which Zappa did not approve. Cohen filed a lawsuit against Zappa in return, which froze the money Zappa and Cohen had gained from an out-of-court settlement with MGM over the rights of the early Mothers of Invention recordings. It also prevented Zappa having access to any of his previously recorded material during the trials. Zappa therefore took his personal master copies of the rock-oriented Zoot Allures (1976) directly to Warner Bros., thereby bypassing DiscReet.In the mid-1970s Zappa prepared material for Läther (pronounced "leather"), a four-LP project. Läther encapsulated all the aspects of Zappa's musical styles—rock tunes, orchestral works, complex instrumentals, and Zappa's own trademark distortion-drenched guitar solos. Wary of a quadruple-LP, Warner Bros. Records refused to release it. Zappa managed to get an agreement with Phonogram Inc., and test pressings were made targeted at a Halloween 1977 release, but Warner Bros. prevented the release by claiming rights over the material. Zappa responded by appearing on the Pasadena, California radio station KROQ, allowing them to broadcast Läther and encouraging listeners to make their own tape recordings. A lawsuit between Zappa and Warner Bros. followed, during which no Zappa material was released for more than a year. Eventually, Warner Bros. issued different versions of much of the Läther material in 1978 and 1979 as four individual albums (five full-length LPs) with limited promotion.Although Zappa eventually gained the rights to all his material created under the MGM and Warner Bros. contracts, the various lawsuits meant that for a period Zappa's only income came from touring, which he therefore did extensively in 1975–77 with relatively small, mainly rock-oriented, bands. Drummer Terry Bozzio became a regular band member, Napoleon Murphy Brock stayed on for a while, and original Mothers of Invention bassist Roy Estrada joined. Among other musicians were bassist Patrick O'Hearn, singer-guitarist Ray White and keyboardist/violinist Eddie Jobson. In December 1976, Zappa appeared as a featured musical guest on the NBC television show Saturday Night Live. Zappa's song "I'm the Slime" was performed with a voice-over by SNL booth announcer Don Pardo, who also introduced "Peaches En Regalia" on the same airing. In 1978, Zappa served both as host and musical act on the show, and as an actor in various sketches. The performances included an impromptu musical collaboration with cast member John Belushi during the instrumental piece "The Purple Lagoon". Belushi appeared as his Samurai Futaba character playing the tenor sax with Zappa conducting. 
Question: What is the first name of the person who prevented Zappa having access to any of his previously recorded material during the trials?

Answer: Herb.


Question: Passage: Spoiled playboy Bob Merrick's (Rock Hudson) reckless behaviour causes him to lose control of his speedboat. Rescuers send for the nearest resuscitator, located in Dr. Phillips's house across the lake. While the resuscitator is being used to save Merrick, Dr. Phillips suffers a heart attack and dies. Merrick ends up a patient at Dr. Phillips's clinic, where most of the doctors and nurses resent the fact that Merrick inadvertently caused Dr. Phillips's death. 
Helen Phillips, Dr. Phillips's widow, receives a flood of calls, letters, and visitors all offering to pay back loans that Dr. Phillips refused to accept repayment of during his life. Many claimed he refused by saying "it was already used up." Edward Randolph, a famous artist and Dr. Phillips's close friend, explains to Helen what that phrase means. This helps her to understand why her husband left little money, even though he had a very successful practice.
Merrick discovers why everyone dislikes him. He runs from the clinic but collapses in front of Helen's car and ends up back at the hospital, where she learns his true identity. After his discharge, Merrick leaves a party, drunk. Merrick runs off the road and ends up at the home of Edward Randolph, who recognizes him. Randolph explains the secret belief that powered his own art and Dr. Phillips's success.  Merrick decides to try out this new philosophy. His first attempt causes Helen to step into the path of a car while trying to run away from Merrick's advances. She is left blind as a result of this accident.
Merrick soberly commits to becoming a doctor, trying to fulfill Dr. Phillips's legacy. He also has fallen in love with Helen and secretly helps her adjust to her blindness under the guise of being simply a poor medical student, Robby. 
Question: What is the last name of the person who understands why her husband left little money?

Answer:
Phillips.
