In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Question: Passage: Located within the KlamathSiskiyou region, known for its high biodiversity, the monument supports 391 vascular plant species as well as many species of bryophyte, lichen, and macrofungi. Trees in the monument include Douglas fir, oak, white fir, and alder. Among the oldest trees is Big Tree, thought to be the widest Douglas fir in the state. It is 41 feet (12 m) in circumference near the base. Its age is estimated at 600 to 800 years, and it was described in the 1930s as 14 feet (4.3 m) in diameter. The monument contains no plants with special conservation status.Species lists for the park include about 50 mammals, 86 birds, 11 reptiles and amphibians, 8 bats, more than 200 arthropods, 8 snails and slugs, 75 butterflies, more than 55 moths, and 8 aquatic macroinvertebrates. Of these species, 160 are found inside the cave. Outside the cave, the black-tailed deer, Steller's jay, the common raven, and Townsend's chipmunk are among animals often seen in the park. Less commonly sighted are the black bear, cougar, northern flying squirrel, and Pacific giant salamander. Springs and other wet places support flatworms, frogs, and snails.Animal species in the park with special conservation status are the northern spotted owl, California mountain kingsnake, tailed frog, Del Norte salamander, northern goshawk, olive-sided flycatcher, little willow flycatcher, Siskiyou gazelle beetle, and Pacific fisher. Five at-risk bat species are found in the cave: Townsend's big-eared bat, and the long-eared, fringed, long-legged, and Yuma myotis.

Answer: What are the names of the at-risk bat species in the park with 50 mammals?

Question: Passage: Radiohead began work on their ninth studio album in September 2014, joined again by Godrich. In 2015 they resumed work in the La Fabrique studio near Saint-Remy-de-Provence, France. The sessions were marred by the death of Godrich's father, and Yorke's separation from his wife, Rachel Owen, who died of cancer several months after the album's completion. In the same year, Yorke contributed a soundtrack, Subterranea, to The Panic Office, an installation of Radiohead artwork in Sydney, Australia, and Junun, a collaboration between Greenwood, Godrich, Israeli composer Shye Ben Tzur and Indian musicians, was released, accompanied by a documentary directed by Anderson. On Christmas Day 2015, Radiohead released a new song, "Spectre", on the audio streaming site SoundCloud. It had been commissioned for the 2015 James Bond film Spectre, but was rejected by the film producers as "too dark".Radiohead's ninth studio album, A Moon Shaped Pool, was released in May 2016 on Radiohead's website and online music stores, followed by retail versions in June via XL Recordings. It was promoted with music videos for the singles "Burn the Witch" and "Daydreaming", the latter directed by Anderson. The album includes several songs written years earlier, including "True Love Waits", and strings and choral vocals arranged by Jonny Greenwood and performed the London Contemporary Orchestra. It was Radiohead's sixth UK number-one album and reached number three in the US. It was the fifth Radiohead album nominated for the Mercury Prize, making Radiohead the most shortlisted act in the award's history, and was nominated for Best Alternative Music Album and Best Rock Song (for "Burn the Witch") at the 59th Annual Grammy Awards. It appeared on several publications' lists of the best albums of the year.

Answer: What is the name of the song that had a music video directed by Anderson?

Question: Passage: While on a hunting trip on Loyalsock Creek north of the park in 1850, brothers Elijah and Clemuel Ricketts were frustrated at having to spend the night on a hotel's parlor floor. In 1851 or 1853 they bought 5,000 acres (2,000 ha), including what is now Lake Ganoga and some of the park, as their own hunting preserve, and built a stone house on the lake shore by 1852 or 1855. The stone house served as their lodge and as a tavern; it was known as "Ricketts Folly" for its isolated location in the wilderness. Clemuel died in 1858 and Elijah bought his share of the land and house. The Ricketts family was not aware of the glens and their waterfalls until about 1865, when they were discovered by two guests from the stone house who went fishing and wandered down Kitchen Creek.Elijah's son Robert Bruce Ricketts, for whom the park is named, joined the Union Army as a private at the outbreak of the American Civil War and rose through the ranks to become a colonel in the artillery. After the war, R. Bruce Ricketts returned to Pennsylvania and in 1869 began purchasing the land around the lake from his father. By 1873 he controlled or owned 66,000 acres (27,000 ha), and eventually this grew to more than 80,000 acres (32,000 ha), including the glens and waterfalls and most of the park.While the stone house had served as a home and inn since its construction, in 1872 R. Bruce Ricketts built a three-story wooden addition north of the house. The addition used lumber from a sawmill Ricketts and his partners operated from 1872 to 1875, about 0.5 miles (0.8 km) southeast of the stone house. The North Mountain House hotel opened in 1873; Ricketts' brother Frank, for whom a park waterfall is named, managed it from then until 1898. Many of the hotel's guests were Ricketts' friends and relations, who arrived after school let out in June and stayed all summer until school resumed in September. In 1876 and 1877, Ricketts ran the first summer school in the United States at his house and hotel; one of the teachers was Joseph Rothrock, later known as the "Father of Forestry" in Pennsylvania.

Answer:
What is the last name of the person who died in 1858?
