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: In September 1930 Heseltine moved with Barbara Peache into a basement flat at 12a Tite Street in Chelsea. With no fresh creative inspiration, he worked in the British Museum to transcribe the music of English composer Cipriani Potter, and made a solo version of "Bethlehem Down" with organ accompaniment. On the evening of 16 December Heseltine met with Van Dieren and his wife for a drink and invited them home afterwards. According to Van Dieren, the visitors left at about 12:15 a.m. Neighbours later reported sounds of movement and of a piano in the early morning. When Peache, who had been away, returned early on 17 December, she found the doors and windows bolted, and smelled coal gas. The police broke into the flat and found Heseltine unconscious; he was declared dead shortly afterwards, apparently as the result of coal gas poisoning.An inquest was held on 22 December; the jury could not determine whether the death was accidental or suicide and an open verdict was returned. Most commentators have considered suicide the more likely cause; Heseltine's close friend Lionel Jellinek and Peache both recalled that he had previously threatened to take his life by gas and the outline of a new will was found among the papers in the flat. Much later, Nigel Heseltine introduced a new theory—that his father had been murdered by Van Dieren, the sole beneficiary of Heseltine's 1920 will, which stood to be revoked by the new one. This theory is not considered tenable by most commentators. The suicide theory is supported (arguably), by the (supposed, accepted) fact that Heseltine/Warlock had put his young cat outside the room before he had turned on the lethal gas.Philip Heseltine was buried alongside his father at Godalming cemetery on 20 December 1930. In late February 1931, a memorial concert of his music was held at the Wigmore Hall; a second such concert took place in the following December.In 2011 the art critic Brian Sewell published his memoirs, in which he claimed that he was Heseltine's illegitimate son, born in July 1931 seven months after the composer's death. Sewell's mother, unnamed, was an intermittent girlfriend, a Roman Catholic  who refused Heseltine's offer to pay for an abortion and subsequently blamed herself for his death. Sewell was unaware of his father's identity until 1986. 
Question: What is the last name of the person whose death could not be determined to be accident or suicide?
Example Output: Heseltine.

Example Input: Passage: Born at Podolskaya Street in Saint Petersburg, Russia, Shostakovich was the second of three children of Dmitri Boleslavovich Shostakovich and Sofiya Vasilievna Kokoulina. Shostakovich's paternal grandfather, originally surnamed Szostakowicz, was of Polish Roman Catholic descent (his family roots trace to the region of the town of Vileyka in today's Belarus), but his immediate forebears came from Siberia. A Polish revolutionary in the January Uprising of 1863–4, Bolesław Szostakowicz would be exiled to Narym (near Tomsk) in 1866 in the crackdown that followed Dmitri Karakozov's assassination attempt on Tsar Alexander II. When his term of exile ended, Szostakowicz decided to remain in Siberia. He eventually became a successful banker in Irkutsk and raised a large family. His son Dmitri Boleslavovich Shostakovich, the composer's father, was born in exile in Narim in 1875 and studied physics and mathematics in Saint Petersburg University, graduating in 1899. He then went to work as an engineer under Dmitri Mendeleev at the Bureau of Weights and Measures in Saint Petersburg. In 1903 he married another Siberian transplant to the capital, Sofiya Vasilievna Kokoulina, one of six children born to a Russian Siberian native.Their son, Dmitri Dmitriyevich Shostakovich, displayed significant musical talent after he began piano lessons with his mother at the age of nine. On several occasions he displayed a remarkable ability to remember what his mother had played at the previous lesson, and would get "caught in the act" of playing the previous lesson's music while pretending to read different music placed in front of him. In 1918 he wrote a funeral march in memory of two leaders of the Kadet party, murdered by Bolshevik sailors.In 1919, at the age of 13, he was admitted to the Petrograd Conservatory, then headed by Alexander Glazunov, who monitored Shostakovich's progress closely and promoted him. Shostakovich studied piano with Leonid Nikolayev after a year in the class of Elena Rozanova, composition with Maximilian Steinberg, and counterpoint and fugue with Nikolay Sokolov, with whom he became friends. Shostakovich also attended Alexander Ossovsky's music history classes. Steinberg tried to guide Shostakovich on the path of the great Russian composers, but was disappointed to see him 'wasting' his talent and imitating Igor Stravinsky and Sergei Prokofiev. Shostakovich also suffered for his perceived lack of political zeal, and initially failed his exam in Marxist methodology in 1926. His first major musical achievement was the First Symphony (premiered 1926), written as his graduation piece at the age of 19. This work brought him to the attention of Mikhail Tukhachevsky, who helped Shostakovich find accommodation and work in Moscow, and sent a driver around in "a very stylish automobile" to take him to a concert. 
Question: What is the full name of the person who was admitted to the Petrograd Conservatory at the age of 13?
Example Output: Dmitri Dmitriyevich Shostakovich.

Example Input: Passage: The one-act opera genre had become increasingly popular in Italy following the 1890 competition sponsored by publisher Edoardo Sonzogno for the best such work, which was won by the young Pietro Mascagni's Cavalleria rusticana. With Tosca essentially completed by November 1899, Puccini sought a new project. Among sources he considered, before proceeding with Madama Butterfly, were three works by French dramatist Alphonse Daudet that Puccini thought might be made into a trilogy of one-act operas.After Butterfly premiered in 1904, Puccini again had difficulty finding a new subject. He further considered the idea of composing three one-act operas to be performed together, but found his publisher, Giulio Ricordi, firmly opposed to such a project, convinced that it would be expensive to cast and produce. The composer then planned to work with his longtime librettist, Giuseppe Giacosa, on an opera about Marie Antoinette, a project frustrated by the librettist's illness. Puccini wrote in November 1905, "Will we go back to it? [Maria Antonietta] If I find three one-act works that suit me, I'll put off M.A."  Puccini pursued neither project, as Giacosa's illness led to his death in September 1906.In March 1907, Puccini wrote to Carlo Clausetti, Ricordi's representative in Naples, proposing three one-act operas based on scenes from stories by Russian novelist Maxim Gorky. By May the composer had set aside this proposal to concentrate on the project which became La fanciulla del West, although he did not wholly abandon the idea of a multiple-opera evening. His next idea in this vein, some years later, was for a two-opera bill, one tragic and one comic; he later expanded this to include a third opera with a mystic or religious tone. By November 1916 Puccini had completed the "tragic" element, which became Il tabarro, but he still lacked ideas for the other two works. He considered staging Il tabarro in combination with his own early work Le Villi, or with other two-act operas which might be used to round out the evening's entertainment. Finally, librettist Giovacchino Forzano presented the composer with two works of his own, which became Suor Angelica and Gianni Schicchi. The latter would be Puccini's first setting of a comic text; although his earlier operas, for example La bohème, contain comic episodes, these are merely ancillary to the drama to provide contrast.Forzano wrote to Tito Ricordi, Giulio's son, on 3 March 1917:
I sent the libretto of Suor Angelica to Maestro Puccini some days ago. He has declared himself – kind as he is – very satisfied ... I have also finished a brief outline of a plot based on Gianni Schicchi. You know the Maestro's opinion of this subject, which is rich in possibilities and whose comic nature is quite out of the ordinary. 
Question: What is the last name of the person whose publisher was Giulio ?
Example Output:
Puccini.
