In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[EX Q]: Passage: Despite the grandeur of Florence, Etty was severely depressed, writing to his brother on 5 October that "I feel so lonely, it is impossible for me to be happy" and complaining of "the vermin in the bed, the dirt and the filth" which he considered "such as no Englishman can have any idea of, who has not witnessed it". His emotional state made it impossible for him to study, and within a month of his arrival in Italy, he began the journey back to England, stopping in Paris on 26 October 1816. There he enrolled in the atelier of Jean-Baptiste Regnault but found the atmosphere rowdy and the studio too full of Frenchmen, and he left after a week. While in Paris he also attended the Académie des Beaux-Arts, and amassed a large quantity of prints from the art shops of Paris. Still homesick, Etty left Paris, returning to London in November.Notwithstanding his unhappiness, Etty appears to have developed as a painter during his travels. For the first time, his two paintings exhibited at the 1817 Summer Exhibition (Bacchanalians: a Sketch and Cupid and Euphrosyne) attracted a favourable review in the press, in this case from William Paulet Carey writing in the Literary Gazette who considered Bacchanalians "a fine classical invention" and Cupid as showing "splendid promise". Carey was later to take great pride in being the first critic to recognise Etty's potential, and continued to champion him throughout his career. In 1818 Etty entered a copy of Damiano Mazza's The Rape of Ganymede—at the time thought to be by Titian—in one of the Royal Academy's painting competitions. Easily the most accomplished entry in the competition, Etty was due to win until two of the other contestants complained that he had technically breached RA rules by briefly removing the painting from Academy premises to work on it at home; they further complained that Etty was technically a professional artist and thus ineligible for the contest despite his still being a student. Etty was disqualified from the competition, but the high quality of his work further raised his prestige within the Academy. Although his income was still low and he was surviving on gifts from his brother, at some point by 1818 Etty hired an assistant, George Henry Franklin. 
Question: Where did Etty enroll in the atelier of Jean-Baptiste Regnault?
[EX A]: Paris.

[EX Q]: Passage: Ferrier gave her first London recital on 28 December 1942 at the National Gallery, in a lunch-time concert organised by Dame Myra Hess. Although she wrote "went off very well" in her diary, Ferrier was disappointed with her performance, and concluded that she needed further voice training. She approached the distinguished baritone Roy Henderson with whom, a week previously, she had sung in Mendelssohn's Elijah. Henderson agreed to teach her, and was her regular voice coach for the remainder of her life. He later explained that her "warm and spacious tone" was in part due to the size of the cavity at the back of her throat: "one could have shot a fair-sized apple right to the back of the throat without obstruction". However, this natural physical advantage was not in itself enough to ensure the quality of her voice; this was due, Henderson says, to "her hard work, artistry, sincerity, personality and above all her character".
Ferrier's performances in the Glyndebourne run, which began on 12 July 1946, earned her favourable reviews, although the opera itself was less well received. On the provincial tour which followed the festival it failed to attract the public and incurred heavy financial losses.
By contrast, when the opera reached Amsterdam it was greeted warmly by the Dutch audiences who showed particular enthusiasm for Ferrier's performance. This was Ferrier's first trip abroad, and she wrote an excited letter to her family: "The cleanest houses and windows you ever did see, and flowers in the fields all the way!" Following her success as Lucretia she agreed to return to Glyndebourne in 1947, to sing Orfeo in Gluck's opera Orfeo ed Euridice. She had often sung Orfeo's aria Che farò ("What is life") as a concert piece, and had recently recorded it with Decca. At Glyndebourne, Ferrier's limited acting abilities caused some difficulties in her relationship with the conductor, Fritz Stiedry; nevertheless her performance on the first night, 19 June 1947, attracted warm critical praise.Ferrier's association with Glyndebourne bore further fruit when Rudolf Bing, the festival's general manager, recommended her to Bruno Walter as the contralto soloist in a performance of Mahler's symphonic song cycle Das Lied von der Erde. This was planned for the 1947 Edinburgh International Festival. Walter was initially wary of working with a relatively new singer, but after her audition his fears were allayed; "I recognised with delight that here potentially was one of the greatest singers of our time", he later wrote. Das Lied von der Erde was at that time largely unknown in Britain, and some critics found it unappealing; nevertheless, the Edinburgh Evening News thought it "simply superb". In a later biographical sketch of Ferrier, Lord Harewood described the partnership between Walter and her, which endured until the singer's final illness, as "a rare match of music, voice and temperament.". 
Question: What is the last name of the person who sang with Roy in Mendelssohn's Elijah?
[EX A]: Ferrier.

[EX Q]: Passage: As an artist, Francis Bacon was a late starter. He painted sporadically and without commitment during the late 1920s and early 1930s, when he worked as an interior decorator and designer of furniture and rugs. He later admitted that his career was delayed because he had spent so long looking for a subject that would sustain his interest. He began to paint images based on the Crucifixion in 1933, when his then-patron Eric Hall commissioned a series of three paintings based on the subject. These abstract figurations contain formal elements typical of their time, including diaphanous forms, flat backgrounds, and surrealist props such as flowers and umbrellas. The art critic Wieland Schmied noted that while the early works are "aesthetically pleasing", they lack "a sense of urgency or inner necessity; they are beautiful, but lifeless". The sentiment is echoed by Hugh Davies, who wrote that Bacon's 1933 paintings "suggest an artist concentrating more on formal than on expressive concerns". Bacon admitted that his early works were not successful; they were merely decorative and lacking in substance. He was often harshly self-critical during this period, and would abandon or destroy canvasses before they were completed. He abandoned the Crucifixion theme, then largely withdrew from painting in frustration, instead immersing himself in love affairs, drinking and gambling.When he returned to the topic of the Crucifixion eleven years later, he retained some of the stylistic elements he had developed earlier, such as the elongated and dislocated organic forms that he now based on Oresteia. He continued to incorporate the spatial device he was to use many times throughout his career—three lines radiating from this central figure, which was first seen in Crucifixion, 1933. Three Studies was painted over the course of two weeks in 1944, when, Bacon recalled, "I was in a bad mood of drinking, and I did it under tremendous hangovers and drink; I sometimes hardly knew what I was doing. I think perhaps the drink helped me to be a bit freer." The painting was executed in a ground-floor flat at 7 Cromwell Place, South Kensington in London. A large back room in the building had been converted into a billiard room by its previous occupant, artist John Everett Millais. It was Bacon's studio by day; at night, abetted by Eric Hall and Bacon's childhood nanny Jessie Lightfoot, it functioned as an illicit casino.Although he had been painting for almost twenty years, Bacon steadfastly insisted that Three Studies was the fons et origo of his career. He destroyed many of his earlier canvasses, and tried to suppress those that had left his studio. Bacon was emphatic that no pre-1944 images be admitted into his canon, and most of the early art critics agreed with this position. The early publications of John Russell and David Sylvester open with the 1944 triptych, and Bacon insisted to his death that no retrospective should feature paintings pre-dating 1944. 
Question: What is the last name of the person who abandoned the Crucifixion theme then largely withdrew from painting in frustration?
[EX A]:
Bacon.
