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.

Passage: In 1987, Trent Reznor played keyboard in a Cleveland, Ohio band called the Exotic Birds, then managed by John Malm Jr. Reznor and Malm became friends, and when Reznor left the Exotic Birds to work on music of his own, Malm informally became his manager. At the time, Reznor was employed as an assistant engineer and janitor at Right Track Studios,  in Cleveland; he asked studio owner Bart Koster for permission to record some demos of his own material for free during unused studio time. Koster agreed and allowed Reznor to use it whenever it was empty, commenting that it cost him "just a little wear on [his] tape heads". While completing the early recordings, Reznor was unable to find a band that could articulate the material as he desired. Instead, inspired by Prince, Reznor played all the instruments, except drums, himself. This role remains Reznor's on most of the band's studio recordings, though he has occasionally involved other musicians and assistants. Nine Inch Nails' debut was at the Phantasy Theater in Lakewood, Ohio on October 21, 1988 as part of the Pretty Hate Machine Tour Series. In 1988, after playing its first shows supporting Skinny Puppy, Reznor's ambition for Nine Inch Nails was to release one 12-inch single on a small European label. Several labels responded favorably to the demo material and Reznor signed with TVT Records. Nine selections from the Right Track demos recorded live in November 1988, collectively known as Purest Feeling, were later released in revised form on the band's first full-length studio release, Pretty Hate Machine (1989). The overall sound on Purest Feeling is lighter than that of Pretty Hate Machine; several songs contain more live drumming and guitar work throughout, as well as a heavier use of samples from films.Reznor coined the name "Nine Inch Nails" because it "abbreviated easily", rather than for "any literal meaning". Other rumored explanations have circulated, alleging that Reznor chose to reference Jesus' crucifixion with nine-inch spikes, or Freddy Krueger's nine-inch fingernails. The English letters NIN are also noted for their resemblance to the modern Hebrew characters of the Tetragrammaton.  The Nine Inch Nails' logo, which consists of the letters [NIИ] set inside a border, was designed by Reznor and Gary Talpas, and first appeared on the music video for Nine Inch Nails' debut single, "Down in It", and was inspired by Tibor Kalman's typography on the Talking Heads album Remain in Light. Talpas, a native of Cleveland, would continue to design Nine Inch Nails packaging art until 1997.

Passage: The first human presence in the region dates to 8,000 years ago when family groups camped where they could hunt or collect plants and seeds. About 2,000 years ago, some groups began growing corn and other crops, leading to an increasingly sedentary lifestyle. Later groups in this period built permanent villages called pueblos. Archaeologists call this the Archaic period and it lasted until c. 500. Baskets, cordage nets, and yucca fiber sandals have been found and dated to this period. The Archaic toolkits included flaked stone knives, drills, and stemmed dart points. The dart points were attached to wooden shafts and propelled by throwing devices called atlatls.By c. 300, some of the archaic groups developed into an early branch of seminomadic Anasazi, the Basketmakers. Basketmaker sites have grass- or stone-lined storage cists and shallow, partially underground dwellings called pithouses. They were hunters and gatherers who supplemented their diet with limited agriculture. Locally collected pine nuts were important for food and trade.

Who coined the term for the period that involved building permanent villages?

Passage: The Creed family—Louis, Rachel, and their children Ellie and Gage—move from Chicago to rural Ludlow, Maine, after Louis is offered a job as a doctor with the University of Maine. They befriend their elderly neighbor Jud Crandall, who takes them to an isolated pet cemetery (misspelled "sematary") in the forest behind the Creed's new home.
On his first day at work, Louis encounters Victor Pascow, a jogger who has been mortally injured after being hit by a truck. He warns Louis about the pet cemetery before he dies, calling Louis by name despite the fact they have not previously met. That night, Pascow comes to Louis as a ghost and leads him to the Pet Sematary, warning him not to cross the barrier because the ground beyond is "sour". Louis awakens, assuming it was a dream, but notices his feet are covered in dirt.
During Thanksgiving while the family is gone, Ellie's cat, Church, is run down on the highway. Realizing that Ellie will be devastated, Jud takes Louis beyond the cemetery and deep into the woods, where they reach an ancient Micmac burial ground. Jud instructs Louis to bury the cat and warns him not to tell anyone else about what they have done. The next day a reanimated Church returns to the house, a shell of what he was before; he stinks, moves sluggishly, and is vicious towards Louis. Jud explains that as a boy he himself revived his beloved pet dog in the Micmac ground, and that although the cat might be different, it will save Ellie the grief of losing her favorite pet.
Sometime later, the young Gage is killed by a truck along the same highway. The family is devastated, and Jud anticipates that Louis is considering burying his son in the Micmac ground, although Louis denies it. Jud believes that introducing Louis to the ritual ground aroused the malevolent forces present there, which caused Gage's death.

Ex Output:

In which city is the pet cemetery located?
