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 195317N 1552017W, 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: Two impecunious English sisters, Ellen and Agnes Isit (Dulcie Gray and Margaret Johnston), unexpectedly inherit a Neapolitan villa from a deceased uncle and move to Italy to view and sell their property. A local man, Salvatore, has since a boy been employed by the deceased uncle becoming major domo and he now manages the villa and its vineyard. Exploring her late uncles' studio, Ellen uncovers a painting of a nude Salvatore as Bacchus.
Soon Ellen becomes drawn to the carefree life of the locals and the romantic charisma of Salvatore, while the prudish Agnes resists. During the raucous revelry of the grape-treading festival, Agnes succumbs to her suppressed desire. Rushing to the balcony she cries out for Salvatore who drops Ellen and climbs from the grape vat and to her bed. The pair are quickly married, and husband Salvatore now is master of the estate.
Soon, Ellen becomes aware of a change in Salvatore's behaviour towards Agnes. Not long after the marriage, Agnes' health begins to deteriorate and Ellen's suspicions are aroused. She expresses her concerns to a visiting English doctor, Benjamin Dench who is Agnes's former fiance'. Ellen is convinced that Agnes is being poisoned. She enlists Dench's help in trying to prove that Salvatore is slowly murdering her sister with arsenic. The villa once belonged to Salvatore's family and he has long been determined to regain ownership. Having poisoned his employer to inherit he had not anticipated the sisters arrival on the scene.
Question: What is the name of the person Salvatore may be poisoning with arsenic?
Agnes Isit.

Passage: "The Thing That Should Not Be" was inspired by the Cthulhu Mythos created by famed horror writer H.P. Lovecraft, with notable direct references to The Shadow Over Innsmouth and to Cthulhu himself, who is the subject matter of the song's chorus. It is considered the heaviest track on the album, with the main riff emulating a beast dragging itself into the sea. The Black Sabbath-influenced guitars are downtuned, creating slow and moody ambiance. "Welcome Home (Sanitarium)" was based on Ken Kesey's novel One Flew Over the Cuckoo's Nest and conveys the thoughts of a patient unjustly caged in a mental institution. The song opens with a section of clean single strings and harmonics. The clean, arpeggiated main riff is played in alternating 44 and 64 time signatures. The song is structured with alternating somber clean guitars in the verses, and distorted heavy riffing in the choruses, unfolding into an aggressive finale. This structure follows a pattern of power ballads Metallica set with "Fade to Black" on Ride the Lightning and would revisit with "One" on ...And Justice for All."Disposable Heroes" is an anti-war song about a young soldier whose fate is controlled by his superiors. With sections performed at 220 beats per minute, it is one of the most intense tracks on the record. The guitar passage at the end of each verse was Hammett's imitation of the sort of music he found in war films. The syncopated riffing of "Leper Messiah" challenges the hypocrisy of the televangelism that emerged in the 1980s. The song describes how people are willingly turned into blind religious followers who mindlessly do whatever they are told. The 136 beats per minute mid-tempo riffing of the verses culminates in a descending chromatic riff in the chorus; it increases to a galloping 184 beats per minute for the middle section that climaxes in a distorted scream of "Lie!". The title derives from the lyrics to the David Bowie song "Ziggy Stardust". "Orion" is a multipart instrumental highlighting Burton's bass playing. It opens with a fade-in bass section, heavily processed to resemble an orchestra. It continues with mid-tempo riffing, followed by a bass solo at half-tempo. The tempo accelerates during the latter part, and ends with music fading out. Burton arranged the middle section, which features its moody bass line and multipart guitar harmonies. "Damage, Inc." rants about senseless violence and reprisal at an unspecified target. It starts with a series of reversed bass chords based on the chorale prelude of Bach's "Come, Sweet Death". The song then jumps into a rapid rhythm with a pedal-point riff in E that Hammett says was influenced by Deep Purple.
Question: What song is structured with alternating somber clean guitars in the verses, and distorted heavy riffing in the choruses?
Welcome Home (Sanitarium).
