Input: Consider Input: Passage: By the late 1950s, Covent Garden was gradually abandoning its policy of productions in the vernacular; such singers as Maria Callas would not relearn their roles in English. This made it easier for Tucker to point up the difference between the two London opera companies. While Covent Garden engaged international stars, Sadler's Wells focused on young British and Commonwealth performers. Colin Davis was appointed musical director in succession to Gibson in 1961. The repertoire continued to mix familiar and unfamiliar operas. Novelties in Davis's time included Pizzetti's Murder in the Cathedral, Stravinsky's Oedipus rex, Richard Rodney Bennett's The Mines of Sulphur and more Janáček. Sadler's Wells's traditional policy of giving all operas in English continued, with only two exceptions: Oedipus rex, which was sung in Latin, and Monteverdi's L'Orfeo, sung in Italian, for reasons not clear to the press. In January 1962, the company gave its first Gilbert and Sullivan opera, Iolanthe, on the day on which the Savoy operas came out of copyright and the D'Oyly Carte monopoly ended.  The production was well received (it was successfully revived for many seasons until 1978) and was followed by a production of The Mikado in May of the same year.The Islington theatre was by now clearly too small to allow the company to achieve any further growth. A study conducted for the Arts Council reported that in the late 1960s the two Sadler's Wells companies comprised 278 salaried performers and 62 guest singers. The company had experience of playing in a large West End theatre, such as its 1958 sell-out production of The Merry Widow that had transferred to the 2,351-seat London Coliseum for a summer season. Ten years later, the lease of the Coliseum became available.  Stephen Arlen, who had succeeded Tucker as managing director, was the primary advocate for moving the company. After intense negotiations and fund-raising, a ten-year lease was signed in 1968.  One of the company's last productions at the Islington theatre was Wagner's The Mastersingers, conducted by Goodall in 1968, which 40 years later was described by Gramophone magazine as "legendary". The company left Sadler's Wells with a revival of the work with which it had re-opened the theatre in 1945, Peter Grimes. Its last performance at the Rosebery Avenue theatre was on 15 June 1968. 
Question: What are the names of the people that wrote the opera The Mikado?

Output: Gilbert.


Input: Consider Input: 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?

Output: Shirley.


Input: Consider Input: Passage: Toward the end of 1961, Kertész broke his contract to Condé Nast Publishing after a minor dispute, and started doing his own work again.  This later period of his life is often referred to as the "International period", when he gained worldwide recognition and his photos were exhibited in many countries. In 1962 his work was exhibited in Venice; in 1963, he was one of the invited artists of the IV Mostra Biennale Internazionale della Fotografia there and he was awarded a gold medal for his dedication to the photographic industry.  Later in 1963, his work was shown in Paris at the Bibliothèque nationale de France. He later visited Argentina to see his younger brother Jenő for the first time in years.  Kertész experimented with color photographs, but only produced a few.
In 1964, soon after John Szarkowski became the photography director at the Museum of Modern Art, he featured Kertész in a solo show. With his work critically acclaimed, Kertész gained recognition in the photographic world as an important artist. 
The work of Kertész was featured in numerous exhibitions throughout the world in his later life, even into his early nineties. Due to his newfound success, in 1965 Kertész was appointed as a member of the American Society of Media Photographers.
His awards rapidly accumulated: 
1974, Guggenheim Fellowship;
1974, Commander of the French Ordre des Arts et des Lettres;
1977, Mayor's Award of Honor for Arts and Culture in New York,
1980 the Medal of the City of Paris, and the first Annual Award of the Association of International Photography Art Dealers in New York; and
1981, honorary Doctorate of Fine Arts from Bard College, and the New York Mayor's Award of Honor for Arts and Culture that year.During this period, Kertész produced a number of new books.  He was able to recover some of the negatives he had left in France decades before.
Despite his successes, Kertész still felt unrecognised as a photographer. His last years were spent travelling to various locations around the globe for his exhibitions, especially Japan, and rekindling friendships with other artists. To deal with the loss of his wife in 1977, Kertész fell back on his new network of friends, often visiting them to talk. By this time, he was said to have learned basic English and talked in what his friends called "Kertészian", a mixture of Hungarian, English and French.In 1979, the Polaroid Corporation gave him one of their new SX-70 cameras, which he experimented with into the 1980s. Still growing in fame, Kertész was granted the National Grand Prize of Photography in Paris in 1982, as well as the 21st Annual George Washington Award from the American Hungarian Foundation the same year. 
Question: What is the name of the person to whom the Polaroid Corporation gave one of their new SX-70 cameras in 1979?


Output: Kertész.
