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.

Passage: In pre-contact times, natives traveling up Mauna Kea were probably guided more by landscape than by existing trails, as no evidence of trails has been found. It is possible that natural ridges and water sources were followed instead. Individuals likely took trips up Mauna Kea's slopes to visit family-maintained shrines near its summit, and traditions related to ascending the mountain exist to this day. However, very few natives reached the summit, because of the strict kapu placed on it.In the early 19th century, the earliest notable recorded ascents of Mauna Kea included the following:
On August 26, 1823, Joseph F. Goodrich, an American missionary, made the first recorded ascent in a single day; however, a small arrangement of stones he observed suggested he was not the first human on the summit. He recorded four ecosystems as he travelled from base to summit, and also visited Lake Waiau.
On June 17, 1825, an expedition from HMS Blonde, led by botanist James Macrae, reached the summit of Mauna Kea. Macrae was the first person to record the Mauna Kea silversword (Argyroxiphium sandwicense), saying: "The last mile was destitute of vegetation except one plant of the Sygenisia tribe, in growth much like a Yucca, with sharp pointed silver coloured leaves and green upright spike of three or four feet producing pendulous branches with brown flowers, truly superb, and almost worth the journey of coming here to see it on purpose."
In January 1834, David Douglas climbed the mountain and described extensively the division of plant species by altitude. On a second climb in July, he was found dead in a pit intended to catch wild cattle. Although murder was suspected, it was probably an accidental fall. The site, Ka lua kauka  19°53′17″N 155°20′17″W, is marked by the Douglas fir trees named for him.
In 1881, Queen Emma traveled to the peak to bathe in the waters of Lake Waiau during competition for the role of ruling chief of the Kingdom of Hawaii.
On August 6, 1889, E.D. Baldwin left Hilo and followed cattle trails to the summit.In the late 19th and early 20th centuries trails were formed, often by the movement of game herds, that could be traveled on horseback. However, vehicular access to the summit was practically impossible until the construction of a road in 1964, and it continues to be restricted. Today, multiple trails to the summit exist, in various states of use. 
Question: What is the full name of the person who was found dead in a pit intended to catch wild cattle?
David Douglas.

Passage: Massenet was a prolific composer; he put this down to his way of working, rising early and composing from four o'clock in the morning until midday, a practice he maintained all his life. In general he worked fluently, seldom revising, although Le roi de Lahore, his nearest approach to a traditional grand opera, took him several years to complete to his own satisfaction. It was finished in 1877 and was one of the first new works to be staged at the Palais Garnier, opened two years previously. The opera, with a story taken from the Mahabharata, was an immense success and was quickly taken up by the opera houses of eight Italian cities. It was also performed at the Hungarian State Opera House, the Bavarian State Opera, the Semperoper, Dresden, the Teatro Real in Madrid, and the Royal Opera House, Covent Garden, in London. After the first Covent Garden performance, The Times summed the piece up in a way that was frequently to be applied to the composer's operas: "M. Massenet's opera, although not a work of genius proper, is one of more than common merit, and contains all the elements of at least temporary success."This period was an early high point in Massenet's career. He had been made a chevalier of the Legion of Honour in 1876, and in 1878 he was appointed professor of counterpoint, fugue and composition at the Conservatoire under Thomas, who was now the director. In the same year he was elected to the Institut de France, a prestigious honour, rare for a man in his thirties. Camille Saint-Saëns, whom Massenet beat in the election for the vacancy, was resentful at being passed over for a younger composer. When the result of the election was announced, Massenet sent Saint-Saëns a courteous telegram: "My dear colleague: the Institut has just committed a great injustice". Saint-Saëns cabled back, "I quite agree." He was elected three years later, but his relations with Massenet remained cool.Massenet was a popular and respected teacher at the Conservatoire. His pupils included Bruneau, Charpentier, Chausson, Hahn, Leroux, Pierné, Rabaud and Vidal. He was known for the care he took in drawing out his pupils' ideas, never trying to impose his own. One of his last students, Charles Koechlin, recalled Massenet as a voluble professor, dispensing "a teaching active, living, vibrant, and moreover comprehensive". According to some writers, Massenet's influence extended beyond his own students. In the view of the critic Rodney Milnes, "In word-setting alone, all French musicians profited from the freedom he won from earlier restrictions." Romain Rolland and Francis Poulenc have both considered Massenet an influence on Debussy's Pelléas et Mélisande; Debussy was a student at the Conservatoire during Massenet's professorship but did not study under him. 
Question: What was the full name of one of Massenet's last students?
Charles Koechlin.

Passage: South Sister, also known as "Charity", is the tallest volcano of the trio, standing at 10,363 feet (3,159 m). The eruptive products range from basaltic andesite to rhyolite and rhyodacite. It is a predominantly rhyolitic stratovolcano overlying an older shield structure. Its modern structure is no more than 50,000 years old, and it last erupted about 2,000 years ago. Although its first eruptive events from 50,000 to 30,000 years ago were predominantly rhyolitic, between 38,000 and 32,000 years ago the volcano began to alternate between dacitic/rhyodacitic and rhyolitic eruptions. The volcano built a broad andesitic cone, forming a steep summit cone of andesite about 27,000 years ago. South Sister remained dormant for 15,000 years, after which its composition shifted from dacitic to more rhyolitic lava. An eruptive episode about 2,200 years ago, termed the Rock Mesa eruptive cycle, first spread volcanic ash from flank vents from the south and southwest flanks, followed by a thick rhyolite lava flow. Next, the Devils Hill eruptive cycle consisted of explosive ash eruptions followed by viscous rhyolitic lava flows. Unlike the previous eruptive period, it was caused by the intrusion of a dike of new silicic magma that erupted from 20 vents on the southeast side and from a smaller line on the north side. These eruptions generated pyroclastic flows and lava domes from vents on the northern, southern, eastern, and southeastern sides of the volcano. These relatively recent, postglacial eruptions suggest the presence of a silicic magma reservoir under South Sister, one that could perhaps lead to future eruptions.
Unlike its sister peaks, South Sister has an uneroded summit crater about 0.25 mi (0.40 km) in diameter that holds a small crater lake known as Teardrop Pool, the highest lake in Oregon. Its cone consists of basaltic andesite along with red scoria and tephra, with exposed black and red inner walls made of scoria. Hodge Crest, a false peak, formed between 28,000 and 24,000 years ago, roughly around the same time as the main cone.Despite its relatively young age, every part of South Sister other than its peak has undergone significant erosion due to Pleistocene and Holocene glaciation. Between 30,000 and 15,000 years ago, South Sister's southern flanks were covered with ice streams, and a small amount of ice extended below 3,600 feet (1,100 m). On the volcano's northern flank, below the summit peak, erosion from these glaciers exposed a headwall about 1,200 feet (370 m) high. During the Holocene, smaller glaciers formed, alternating between advance and retreat, depositing moraines and till between 7,000 and 9,000 feet (2,100 and 2,700 m) on the mountain. The Lewis and |Clark glaciers have cirques, or glacial valleys, that made the outer walls of the crater rim significantly steeper. The slopes of South Sister contain small glaciers, including the Lost Creek and Prouty glaciers. 
Question: What is the name of the cycle that generated pyroclastic flows and lava domes from vents on the northern, southern, eastern, and southeastern sides of the volcano?

Devils Hill eruptive cycle.
