PROBLEM: 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?

SOLUTION: Cosimo.

PROBLEM: Passage: New York City bouncer Frank "Tony Lip" Vallelonga is searching for new employment while the Copacabana nightclub, where he works, is closed for renovations. He is invited to an interview with Doctor Don Shirley, an eccentric African American pianist who is looking for a driver for his eight-week concert tour through the Midwest and Deep South. Don hires Tony on the strength of his references. They embark with plans to return to New York on Christmas Eve. Don's record label gives Tony a copy of the Green Book, a guide for African-American travelers to find motels, restaurants, and filling stations that would serve them.They begin the tour in the Midwest before eventually heading farther south. Tony and Don initially clash as  Don is disgusted by Tony's habits while Tony feels uncomfortable being asked to act with more refinement. As the tour progresses, Tony is impressed with Don's talent on the piano, and increasingly appalled by the discriminatory treatment that Don receives from his hosts and the general public when he is not on stage. A group of white men threatens Don's life in a bar and Tony rescues him. He instructs Don not to go out without him for the rest of the tour. 
Question: What is the last name of the person who Tony rescues?

SOLUTION: Shirley.

PROBLEM: Passage: Giovanni Battista Barbirolli was born in Southampton Row, Holborn, London, the second child and eldest son of an Italian father and a French mother. He was a British national from birth, and as Southampton Row is within the sound of Bow Bells, Barbirolli always regarded himself as a Cockney. His father, Lorenzo Barbirolli (1864–1929), was a Venetian violinist who had settled in London with his wife, Louise Marie, née Ribeyrol (1870–1962). Lorenzo and his father had played in the orchestra at La Scala, Milan, where they had taken part in the première of Otello in 1887. In London they played in West End theatre orchestras, principally that of the Empire, Leicester Square.
The young Barbirolli began to play the violin when he was four, but soon changed to the cello. He later said that this was at the instigation of his grandfather who, exasperated at the child's habit of wandering around while practising the violin, bought him a small cello to stop him from "getting in everybody's way". His education at St. Clement Danes Grammar School overlapped, from 1910, with a scholarship at Trinity College of Music. As a Trinity student, he made his concert debut in a cello concerto in the Queen's Hall in 1911. The following year he won a scholarship to the Royal Academy of Music, which he attended from 1912 to 1916, studying harmony, counterpoint and theory under Dr. J. B. McEwen and the cello with Herbert Walenn. In 1914 he was joint winner of the academy's Charles Rube Prize for ensemble playing, and in 1916 The Musical Times singled him out as "that excellent young 'cello player, Mr Giovanni Barbirolli." The principal of the Academy, Sir Alexander Mackenzie, had forbidden students to play the chamber music of Ravel, which he regarded as "a pernicious influence". Barbirolli was keenly interested in modern music, and he and three colleagues secretly rehearsed Ravel's String Quartet in the privacy of a men's lavatory in the Academy.From 1916 to 1918 Barbirolli was a freelance cellist in London. He recalled, "My first orchestral engagement was with the Queen's Hall Orchestra – I was probably the youngest orchestral musician ever, joining them in 1916. We had an enormous repertory – six concerts a week, three hours or more rehearsal a day. In those days we were happy if we began and finished together". While playing in the Queen's Hall Orchestra, Barbirolli also played in the opera pit for the Beecham and Carl Rosa opera companies, in recitals with the pianist Ethel Bartlett, with orchestras in theatres, cinemas, hotels and dance-halls, and, as he said, "everywhere except the street". During the last year of the First World War, Barbirolli enlisted in the army and became a lance-corporal in the Suffolk Regiment. Here he had his first opportunity to conduct, when an orchestra of volunteers was formed. He later described the experience:.

Ravel.
