PROBLEM: Passage: Colour lies at the heart of Messiaen's music. He believed that terms such as "tonal", "modal" and "serial" are misleading analytical conveniences. For him there were no modal, tonal or serial compositions, only music with or without colour. He said that Claudio Monteverdi, Mozart, Chopin, Richard Wagner, Mussorgsky and Stravinsky all wrote strongly coloured music.In some of Messiaen's scores, he notated the colours in the music (notably in Couleurs de la cité céleste and Des canyons aux étoiles...)—the purpose being to aid the conductor in interpretation rather than to specify which colours the listener should experience. The importance of colour is linked to Messiaen's synaesthesia, which he said caused him to experience colours when he heard or imagined music (he said that he did not perceive the colours visually). In his multi-volume music theory treatise Traité de rythme, de couleur, et d'ornithologie ("Treatise of Rhythm, Colour and Birdsong"), Messiaen wrote descriptions of the colours of certain chords. His descriptions range from the simple ("gold and brown") to the highly detailed ("blue-violet rocks, speckled with little grey cubes, cobalt blue, deep Prussian blue, highlighted by a bit of violet-purple, gold, red, ruby, and stars of mauve, black and white. Blue-violet is dominant").When asked what Messiaen's main influence had been on composers, George Benjamin said, "I think the sheer ... colour has been so influential, ... rather than being a decorative element, [Messiaen showed that colour] could be a structural, a fundamental element, ... the fundamental material of the music itself.". 
Question: What is the name of the person who said Monteverdi, Mozart, Chopin, Wagner, Mussorgsky, and Stravinsky all wrote strongly coloured music?

SOLUTION: Messiaen.

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: As Pei, neared the end of his secondary education, he decided to study at a university. He was accepted to a number of schools, but decided to enroll at the University of Pennsylvania. Pei's choice had two roots. While studying in Shanghai, he had closely examined the catalogs for various institutions of higher learning around the world. The architectural program at the University of Pennsylvania stood out to him. The other major factor was Hollywood. Pei was fascinated by the representations of college life in the films of Bing Crosby, which differed tremendously from the academic atmosphere in China. "College life in the U.S. seemed to me to be mostly fun and games", he said in 2000. "Since I was too young to be serious, I wanted to be part of it ... You could get a feeling for it in Bing Crosby's movies. College life in America seemed very exciting to me. It's not real, we know that. Nevertheless, at that time it was very attractive to me. I decided that was the country for me."In 1935 Pei boarded a boat and sailed to San Francisco, then traveled by train to Philadelphia. What he found, however, differed vastly from his expectations. Professors at the University of Pennsylvania based their teaching in the Beaux-Arts style, rooted in the classical traditions of Greece and Rome. Pei was more intrigued by modern architecture, and also felt intimidated by the high level of drafting proficiency shown by other students. He decided to abandon architecture and transferred to the engineering program at Massachusetts Institute of Technology (MIT). Once he arrived, however, the dean of the architecture school commented on his eye for design and convinced Pei to return to his original major.MIT's architecture faculty was also focused on the Beaux-Arts school, and Pei found himself uninspired by the work. In the library he found three books by the Swiss-French architect Le Corbusier. Pei was inspired by the innovative designs of the new International style, characterized by simplified form and the use of glass and steel materials. Le Corbusier visited MIT in November 1935, an occasion which powerfully affected Pei: "The two days with Le Corbusier, or 'Corbu' as we used to call him, were probably the most important days in my architectural education." Pei was also influenced by the work of US architect Frank Lloyd Wright. In 1938 he drove to Spring Green, Wisconsin, to visit Wright's famous Taliesin building. After waiting for two hours, however, he left without meeting Wright. 
Question: What is the first name of the person whose house was in Spring Green, Wisconsin?

SOLUTION:
Frank.
