Passage: A young American man arrives in Palermo by plane. A taxi driver at the airport immediately gets word to Frank Ginetta, who hides, armed with a gun, until he realizes that the visitor he's been warned about is actually his younger brother Vinnie.
Frank happily welcomes his brother and takes him home, catching up on old times. But his wife, Ida, reminds him that "they're going to send someone," suggesting that perhaps Vinnie is the one.
In a flashback, Frank recalls better times in New York City, beginning with Vinnie's homecoming from military service and subsequent marriage to Emma Bertolo. The father of the bride, Dominick Bertolo is a Mafia don, as is the groom's brother, Frank. And among those paying their respects as guests at the wedding are mob leaders like Egan, Rotherman and Levin, who are the equals of Frank and Dominick in the New York region's organized crime.
These capos within the Organization meet as a board to coordinate their business. The majority becomes increasingly unhappy with Frank's position, as he seems opposed to every new idea. Frank also dispenses justice on his own in the old Sicilian fashion, without seeking approval from the others. They, not being of Sicilian origin, are trying to leave behind the old traditional methods, such as when two of Frank's hit men kill a stool pigeon in the marshes and leave him tied to a chair with a canary stuffed in his mouth, as a warning to others who might talk too much.
Frank still fondly remembers his father, who also was a mafioso who was assassinated in a hit. Vinnie is more of a businessman, and takes sides with the other board members in ventures they intend to pursue without his brother. Frank resents this, striking Vinnie for defying him and insisting to the board that Vinnie will have no part in what they have planned. 
Question: What is the first name of the don's brother's wife?

Ex Output:
Emma.

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?

Ex Output:
Cosimo.

Passage: Brian Epstein managed the Beatles from 1962 until his death in 1967. He had no previous experience managing artists, but he had a strong influence on the group's dress code and attitude on stage. Lennon initially resisted his attempts to encourage the band to present a professional appearance, but eventually complied, saying, "I'll wear a bloody balloon if somebody's going to pay me." McCartney took over on bass after Sutcliffe decided to stay in Hamburg, and Best was replaced with drummer Ringo Starr; this completed the four-piece line-up that would remain until the group's break-up in 1970. The band's first single, "Love Me Do", was released in October 1962 and reached No. 17 on the British charts. They recorded their debut album, Please Please Me, in under 10 hours on 11 February 1963, a day when Lennon was suffering the effects of a cold, which is evident in the vocal on the last song to be recorded that day, "Twist and Shout". The Lennon–McCartney songwriting partnership yielded eight of its fourteen tracks. With a few exceptions, one being the album title itself, Lennon had yet to bring his love of wordplay to bear on his song lyrics, saying: "We were just writing songs ... pop songs with no more thought of them than that – to create a sound. And the words were almost irrelevant". In a 1987 interview, McCartney said that the other Beatles idolised Lennon: "He was like our own little Elvis ... We all looked up to John. He was older and he was very much the leader; he was the quickest wit and the smartest.". 
Question: What was the last name of the person that was like Elvis?

Ex Output:

Lennon.
