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.

[Q]: 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?
[A]: Heseltine.


[Q]: Passage: Handel joined the Hamburg opera house when it was experiencing a period of considerable artistic success. This blossoming followed the arrival of Reinhard Keiser, who had become musical director at the Gänsemarkt in about 1697, and in 1703 succeeded Johann Kusser as the theatre's manager. Born in 1674, Keiser had studied under Johann Schelle and probably Johann Kuhnau at the Thomasschule zu Leipzig.  In 1694 he was employed as a court composer at Brunswick, where in three years he composed seven operas, at least one of which (Mahumeth) was performed in Hamburg. According to Handel's biographer Donald Burrows, Keiser was a good judge of popular taste, with a flair for writing Italian-style arias.  Between 1697 and 1703, prior to Handel's arrival, about a dozen more Keiser operas had been staged at the Gänsemarkt. Despite his on-stage successes, Keiser was an unreliable general manager, with expensive private tastes and little financial acumen, often at odds with his creditors.It is possible that Keiser, who had connections in the Halle area, had heard of Handel and was directly instrumental in securing the latter's post in the Gänsemarkt orchestra; certainly he was a considerable influence on the younger man in the three years that Handel spent in Hamburg. Another important Gänsemarkt colleague was the house composer and singer Johann Mattheson, who noted Handel's rapid progress in the orchestra from back-desk violinist to harpsichord soloist, a role in which, said Mattheson, "he showed himself a man—a thing which no one had before suspected, save I alone". Mattheson was less complimentary on Handel's early efforts at composition: "He composed very long, long arias, and really interminable cantatas", before, it seems, "the lofty schooling of opera ... trimmed him into other fashions". 
Question: What is the last name of the person who was employed as a court composer at Brunswick in 1694?
[A]: Keiser.


[Q]: Passage: The Rogue River begins at Boundary Springs on the border between Klamath and Douglas counties near the northern edge of Crater Lake National Park. Although it changes direction many times, it flows generally west for 215 miles (346 km) from the Cascade Range through the Rogue River – Siskiyou National Forest and the Klamath Mountains to the Pacific Ocean at Gold Beach. Communities along its course include Union Creek, Prospect, Trail, Shady Cove, Gold Hill and Rogue River, all in Jackson County; Grants Pass and Galice in Josephine County; and Agness, Wedderburn and Gold Beach in Curry County. Significant tributaries include the South Fork Rogue River, Elk Creek, Bear Creek, the Applegate River, and the Illinois River. Arising at 5,320 feet (1,622 m) above sea level, the river loses more than 1 mile (1.6 km) in elevation by the time it reaches the Pacific.
It was one of the original eight rivers named in the National Wild and Scenic Rivers Act of 1968, which included 84 miles (135 km) of the Rogue, from 7 miles (11.3 km) west of Grants Pass to 11 miles (18 km) east of the mouth at Gold Beach. In 1988, an additional 40 miles (64 km) of the Rogue between Crater Lake National Park and the unincorporated community of Prospect was named Wild and Scenic. Of the river's total length, 124 miles (200 km), about 58 percent is Wild and Scenic. The Rogue is one of only three rivers that start in or east of the Cascade Range in Oregon and reach the Pacific Ocean. The others are the Umpqua River and Klamath River. These three Southern Oregon rivers drain mountains south of the Willamette Valley; the Willamette River and its tributaries drain north along the Willamette Valley into the Columbia River, which starts in British Columbia rather than Oregon. 
Question: What state does the Rogue River start in?
[A]:
Oregon.
