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.

Example Input: 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 Academie 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 Ganymedeat the time thought to be by Titianin 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: What was easily the most accomplished entry in the competition?
Example Output: a copy of Damiano Mazza's The Rape of Ganymede.

Example Input: Passage: Throughout the early years of the July Monarchy, Alkan continued to teach and play at public concerts and in eminent social circles. He became a friend of many who were active in the world of the arts in Paris, including Franz Liszt (who had been based there since 1827), George Sand, and Victor Hugo. It is not clear exactly when he first met Frederic Chopin, who arrived in Paris in September 1831. In 1832 Alkan took the solo role in his first Concerto da camera for piano and strings at the Conservatoire. In the same year, aged 19, he was elected to the influential Societe Academique des Enfants d'Apollon (Society of the Children of Apollo), whose members included Luigi Cherubini, Fromental Halevy, the conductor Francois Habeneck, and Liszt, who had been elected in 1824 at the age of twelve. Between 1833 and 1836 Alkan participated at many of the Society's concerts. Alkan twice competed unsuccessfully for the Prix de Rome, in 1832 and again in 1834; the cantatas which he wrote for the competition, Hermann et Ketty and L'Entree en loge, have remained unpublished and unperformed.In 1834 Alkan began his friendship with the Spanish musician Santiago Masarnau, which was to result in an extended and often intimate correspondence which only came to light in 2009. Like virtually all of Alkan's correspondence, this exchange is now one-sided; all of his papers (including his manuscripts and his extensive library) were either destroyed by Alkan himself, as is clear from his will, or became lost after his death. Later in 1834 Alkan made a visit to England, where he gave recitals and where the second Concerto da camera was performed in Bath by its dedicatee Henry Ibbot Field; it was published in London together with some solo piano pieces. A letter to Masarnau and a notice in a French journal that Alkan played in London with Moscheles and Cramer, indicate that he returned to England in 1835. Later that year, Alkan, having found a place of retreat at Piscop outside Paris, completed his first truly original works for solo piano, the Twelve Caprices, published in 1837 as Opp. 12, 13, 15 and 16. Op. 16, the Trois scherzi de bravoure, is dedicated to Masarnau. In January 1836, Liszt recommended Alkan for the post of Professor at the Geneva Conservatoire, which Alkan declined, and in 1837 he wrote an enthusiastic review of Alkan's Op. 15 Caprices in the Revue et gazette musicale.
Question: Whose cantatas written for the competition, Hermann et Ketty and L'Entree en loge, have remained unpublished and unperformed?
Example Output: Alkan.

Example Input: Passage: Eons ago, Bor, father of Odin, clashes with the Dark Elf Malekith, who seeks to unleash a weapon known as the Aether on the nine realms. After conquering Malekith's forces, including enhanced warriors called the Kursed, on their home world of Svartalfheim, Bor safeguards the Aether within a stone column. Unknown to Bor, Malekith as well as his lieutenant Algrim and a handful of Dark Elves escape into suspended animation.
In present-day Asgard, Loki stands imprisoned for his war crimes on Earth. Meanwhile, Thor, alongside warriors Fandral, Volstagg, and Sif, repel marauders on Vanaheim, home of their comrade Hogun; it is the final battle in a war to pacify the Nine Realms following the reconstruction of the Bifrost, the "Rainbow Bridge" between realms, which had been destroyed two years earlier. The Asgardians soon learn that the Convergence, a rare alignment of the Nine Realms, is imminent; as the event approaches, portals linking the worlds appear at random.
In London, astrophysicist Dr. Jane Foster and her intern Darcy Lewis travel to an abandoned factory where such portals have appeared, disrupting the laws of physics around them. Separating from the group, Foster is teleported to another world, where she is infected by the Aether. Heimdall alerts Thor that Foster has moved beyond his near all-seeing vision, leading Thor to Earth. When Thor finds Foster, she inadvertently releases an unearthly force, and Thor returns with her to Asgard. Odin, recognizing the Aether, warns that the Aether will not only kill Foster but that its return heralds a catastrophic prophecy.
Question: Who initially safeguarded what later infects Jane Foster?
Example Output:
Bor.
