Passage: The film begins at Heathrow Airport, where a Polish immigrant named Lena Malley is working a shift as a cleaner. While there, her colleague Birdie helps her to clean the toilets. The two begin to talk and Lena reveals that she lives alone and doesn't keep in touch with her family. Birdie introduces Lena to her adopted brother Elbie, who also works at the airport and is a mute. Lena tells Birdie that she doesn't get on with her family. While talking, Lena notices scars on Birdie's arm; Birdie explains that she used to have behavioral problems; but that she's better now. At the end of the shift Lena misses her bus so Birdie tells her that her dad will drive Lena home if they walk to Birdie's house.
Upon arriving at the house Lena is knocked out from behind and injected with a syringe. She wakes up tied to a chair to the sound of screaming coming from another room. Moments later Mum and Dad enter the room and introduce themselves. Mum tells Lena that if she does what she is told everything will be ok. Lena is unable to respond because of the injection she received earlier and Mum proceeds to inject her with a sedative. When she wakes up again Mum begins carving marks into her back. 
Lena is unable to speak, and Mum tells her to not try to talk. She gives Lena another injection, and Lena falls asleep. She wakes up later, tied to a frame. Mum tells her that she wanted another girl to come and live there. Mum then pierces Lena's skin with some metal and carves some marks into her back. Following this incident Lena is taken to see Dad who tells her that in his house she will follow his rules
At breakfast, the family are watching pornography. Lena makes an escape attempt but Dad grabs her and Elbie drags her back to the table.

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?

Ex Output:
David Douglas.

Passage: After the painter's death in 1528, the portraits were held by his brother, and then his brother's widow before they passed into the collection of Willibald Imhoff, a grandson of Dürer's friend Willibald Pirckheimer. Inventories from the Imhoff collection from 1573–74, 1580 and 1588 list both panels. The next surviving Imhoff inventory, of 1628, again lists the mother's portrait, but it disappears after mention in the 1633–58 account books of Hans Hieronymus Imhoff, after which its whereabouts became unknown. Dürer expert Matthias Mende described the missing portrait of Barbara Holper as "among the most severe losses in the Dürer oeuvre".
In 1977, art historian Lotte Brand Philip proposed that Unknown Woman in a Coif, held by the Germanisches Nationalmuseum in Nuremberg, was the original portrait of Barbara Holper. The Nuremberg panel was previously thought to have originated from a member of Wolgemut's workshop, a Franconian artist in his circle, or the anonymous Mainz painter Master W. B. Brand Philip's attribution was based on striking similarities in composition and its shared tone, theme and size with the father panel at the Uffizi. In both works the sitters are holding rosary beads, and Dürer attentively describes their hands. Both portraits show the sitter in the same pose, against a similarly coloured background. Both are lit from the upper left. The boards are identically cut in width and depth, although 3 cm was removed from the left edge of Barbara's panel. Brand Philip noted the similarities between the panel and Dürer's 1514 charcoal drawing Portrait of the Artist's Mother at the Age of 63. Fedja Anzelewsky agreed with the attribution, noting that both portraits bear, on their reverse, the catalogue number recorded in the Imhoff inventories, as well as "precisely the same design of masses of dark clouds".Anzelewsky speculated that the father's portrait, which was not listed in the 1628 Imhoff inventory, had been broken off and sold to Rudolph II of Austria. Hans Hieronymus Imhoff's lukewarm description of Barbara's portrait—"the mother of Albrecht Dürer in oil colors on wood, [but] there are many who do not believe it to be a work of Dürer"—led Brand Philip to conclude that Albrecht's panel was likely sold individually as the more accomplished and marketable of the two. The attribution is widely accepted today. In 2013 Stephan Kemperdick noted the sophistication of the Nuremberg portrait and that its three-dimensional modeling of the head displays a level of skill beyond Wolgemut and his circle.The two panels were reunited in 2012 during a Dürer exhibition in Nuremberg having been separated since sometime between 1588 and 1628. 
Question: What is the last name of the subject of the painting that Hans Hieronymus Imhoff gave a lukewarm description for?

Ex Output:

Holper.
