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 1898 the RCM offered Holst a further year's scholarship, but he felt that he had learned as much as he could there and that it was time, as he put it, to "learn by doing". Some of his compositions were published and performed; the previous year The Times had praised his song "Light Leaves Whisper", "a moderately elaborate composition in six parts, treated with a good deal of expression and poetic feeling".Occasional successes notwithstanding, Holst found that "man cannot live by composition alone"; he took posts as organist at various London churches, and continued playing the trombone in theatre orchestras. In 1898 he was appointed first trombonist and répétiteur with the Carl Rosa Opera Company and toured with the Scottish Orchestra. Though a capable rather than a virtuoso player he won the praise of the leading conductor Hans Richter, for whom he played at Covent Garden. His salary was only just enough to live on, and he supplemented it by playing in a popular orchestra called the "White Viennese Band", conducted by Stanislas Wurm.Holst enjoyed playing for Wurm, and learned much from him about drawing rubato from players. Nevertheless, longing to devote his time to composing, Holst found the necessity of playing for "the Worm" or any other light orchestra "a wicked and loathsome waste of time". Vaughan Williams did not altogether agree with his friend about this; he admitted that some of the music was "trashy" but thought it had been useful to Holst nonetheless: "To start with, the very worst a trombonist has to put up with is as nothing compared to what a church organist has to endure; and secondly, Holst is above all an orchestral composer, and that sure touch which distinguishes his orchestral writing is due largely to the fact that he has been an orchestral player; he has learnt his art, both technically and in substance, not at second hand from text books and models, but from actual live experience."With a modest income secured, Holst was able to marry Isobel; the ceremony was at Fulham Register Office on 22 June 1901. Their marriage lasted until his death; there was one child, Imogen, born in 1907. In 1902 Dan Godfrey and the Bournemouth Municipal Orchestra premiered Holst's symphony The Cotswolds (Op. 8), the slow movement of which is a lament for William Morris who had died in October 1896, three years before Holst began work on the piece. In 1903 Adolph von Holst died, leaving a small legacy. Holst and his wife decided, as Imogen later put it, that "as they were always hard up the only thing to do was to spend it all at once on a holiday in Germany". 
Question: What is the name of the person whose orchestral writing, according to Vaughan Williams, is distinguished by a "sure touch" that is "due largely to the fact that he has been an orchestral player"?

A: Holst.

Q: Passage: De Long's party found no immediate sign at their landing-place of any human habitation, and had only a sketchy idea of where they were—Petermann's map provided few useful details. On September 19, having buried their non-essential possessions in a mound marked by a tent pole, they set out in search of settlements. Progress was hampered by the poor physical condition of the men, in particular Eriksen, who was badly affected by frostbite. On September 21 they halted at two empty huts, probably part of a hunting camp, where Alexey raised spirits by shooting a deer to replenish their dwindling food stocks. De Long allowed his exhausted party several days' rest before resuming the march.On September 28 the party found a large hut, with signs of recent occupation–edible food in the store, and moccasin tracks in the snow. When searches in the locality brought no sign of people, De Long decided to move on. By October 4, Eriksen could not continue; the party halted at another abandoned hut where, on October 6, Eriksen died. On October 9, with the condition of several men worsening, De Long decided to send two of the fittest in the group, Nindemann and Noros, to seek help. Ambler was offered the opportunity to go with them, but felt that his duty as a doctor required him to stay with the main body.For the next week De Long's party struggled on, sometimes making barely a mile a day. Although they jettisoned more of their possessions on the way, De Long insisted on carrying his maps and journals. His entry for October 10 recorded that there was "nothing for supper but a spoonful of glycerine". A few days later Alexey, the group's principal hunter, shot a ptarmigan which provided soup. But Alexey was weakening, and on October 17 he died.On October 20, trapped by the weather and without supplies, the party came to a final halt. Throughout the march De Long had written up his journal each day, but after October 20 his entries became intermittent, largely limited to terse statements of the dying and the dead. He noted the deaths of Kaak and Lee on October 21, Iverson on the 28th, Dressler on the 29th. His last entry, dated October 30, records the deaths of Boyd and Görtz and ends "Mr Collins dying". 
Question: What is the last name of the person who entry for October 10 recorded that there was "nothing for supper but a spoonful of glycerine?"?

A: De Long.

Q: Passage: The east–west trail begins at the Poughkeepsie Bridge, by Haviland Road. The 1.28-mile (2.06 km) Poughkeepsie Bridge was opened as a pedestrian walkway in 2009. The bridge is a National Recreation Trail, and connects to the Dutchess Rail Trail to the east, creating a contiguous 18.2-mile (29.3 km) rail trail system that spans both Ulster and Dutchess counties.The Hudson Valley trail continues 0.5 miles (0.80 km) west from the Poughkeepsie Bridge to a bridge over Mile Hill Road, then another 0.1 miles (0.16 km) to a crossing at US 9W. At the 1-mile (1.6 km) mark, the trail reaches a bridge over Vineyard Avenue. About 1.5 miles (2.4 km) from the bridge, the trail crosses under New Paltz Road. Almost 0.5 miles (0.80 km) from this road, the trail reaches the Black Creek Wetlands Complex. Black Creek is one of the two "principal streams" to run through Lloyd; it bisects the town as it flows north and pools in a pond. The wetlands complex itself is important for water drainage. Part of New York State Department of Environmental Conservation region 3, the complex contains Plutarch Swamp and one of the region's largest dwarf shrub bogs, hosting a variety of rare species. The complex also includes the Swarte Kill, Lloyd's second major waterway. The trail continues an additional 0.5-mile (0.80 km) past the beginning of the complex to Tony Williams Park.There are four parking areas along the trail, by Haviland Road, Commercial Avenue, the Rotary pavilion, and at Tony Williams Park. The trail is 12 feet (3.7 m) wide and 4 miles (6.4 km) long; it is paved with asphalt and suitable for hiking, bicycling, horseback riding, roller blading, and cross country skiing.In 2018, Hudson Valley law firm Mainetti & Mainetti, P.C. published an updated bicycle map that showed the proposed route of the Hudson Valley Rail Trail, and how it links the Walkill Valley Rail Trail and River-to-Ridge-Trail with the Dutchess County Rail Trail. 
Question: What is the total length in miles is the Hudson Valley Rail Trail?

A:
4 miles.
