instruction:
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: There are over 40 species of mammals in the Pine Creek Gorge. Leonard Harrison State Park's extensive forest cover makes it a habitat for "big woods" wildlife, including white-tailed deer, black bear, wild turkey, red and gray squirrels. Less common creatures include bobcats, coyote, fishers, river otters, and timber rattlesnakes. There are over 26 species of fish in Pine Creek, including trout, suckers, fallfish, and rock bass. Other aquatic species include crayfish and frogs.Several species have been reintroduced to the gorge. White-tailed deer were imported from Michigan and released throughout Pennsylvania to reestablish what had once been a thriving population. The current population of deer in Pennsylvania are descended from the original stock introduced beginning in 1906, after the lumberman had moved out of the area. The deer population has grown so much that today they exceed their carrying capacity in many areas. River otters were successfully reintroduced in 1983 and now breed in the gorge. Despite the fears of anglers, their diet is only 5 percent trout.Fishers, medium-sized weasels, were reintroduced to Pine Creek Gorge as part of an effort to establish a healthy population of fishers in Pennsylvania. Prior to the lumber era, fishers were numerous throughout the forests of Pennsylvania. They are generalized predators and will hunt any smaller creatures in their territory, including porcupines. Elk have been reintroduced west of the gorge in Clinton County and occasionally wander near the west rim of the canyon. Coyotes have come back on their own. Invasive insect species in the gorge include gypsy moths, which eat all the leaves off trees, especially oaks, and hemlock woolly adelgids, which weaken and kill hemlocks. Invasive plant species include purple loosestrife and Japanese knotweed.
answer:
What is the full name of the place that have had several species reintroduced?


question:
Passage: A remix album, titled Year Zero Remixed, was released in November 2007. Due to the expiration of his contract with Interscope Records, the album's release, marketing, and promotion were completely in Reznor's control. The album features remixes from artists including The Faint, Ladytron, Bill Laswell, Saul Williams, Olof Dreijer of The Knife, and Sam Fogarino of Interpol. Reznor himself strongly supports fan-made remixes of songs from the album, as evidenced by his decision to upload every song in multi-track form to the then-newly launched Nine Inch Nails remix website.  Instrumental versions of the songs on Year Zero are available at the site for download in multiple formats, including MP3, WAV, GarageBand, and Ableton Live formats.
A planned film adaption of Year Zero became a television project in 2007. Reznor met with various writers and pitched the idea to television networks. The 2007–08 Writers Guild of America strike affected the pre-production stage. Nevertheless, Reznor commented in 2008 that the project is "still churning along", and that he had begun working with American film producer Lawrence Bender. In 2010, Reznor started developing the Year Zero miniseries with HBO and BBC Worldwide Productions. Reznor and Bender collaborated with Carnivàle writer Daniel Knauf to create the science fiction epic. When asked about the miniseries during an "Ask Me Anything" session on Reddit on November 13, 2012, Reznor said it was "currently in a holding state" and explained, "We [Reznor and Sheridan] didn't find the right match with a writer, and really have been avoiding doing what we should have done from the beginning: write it ourselves. [...] This project means a lot to me and will see the light of day in one form or another." In 2017, during an interview promoting new Nine Inch Nails EP Add Violence, Reznor said that "They got so far as hiring a writer for it, but then it fell to shit because we never had the right writer. I should have just done it [myself].".
answer:
What is the last name of the person whose contract expired?


question:
Passage: In 1823, a year after independence, slaves made up 29% of the population of Brazil, a figure which fell throughout the lifetime of the Empire: from 24% in 1854, to 15.2% in 1872, and finally to less than 5% in 1887—the year before slavery was completely abolished. Slaves were mostly adult males from southwestern Africa. Slaves brought to Brazil differed ethnically, religiously and linguistically, each identifying primarily with his or her own nation of origin, rather than by a shared African ethnicity. Some of the slaves brought to the Americas had been captured while fighting intertribal wars in Africa and had then been sold to slave dealers.Slaves and their descendants were usually found in regions devoted to producing exports for foreign markets. Sugarcane plantations on the eastern coast of the northeast region during the 16th and 17th centuries are typical of economic activities dependent on slave labor. In northern Maranhão province, slave labor was used in cotton and rice production in the 18th century. In this period, slaves were also exploited in Minas Gerais province where gold was extracted. Slavery was also common in Rio de Janeiro and São Paulo during the 19th century for the cultivation of coffee which became vital to the national economy. The prevalence of slavery was not geographically uniform across Brazil. Around 1870 only five provinces (Rio de Janeiro with 30%, Bahia with 15%, Minas Gerais with 14%, São Paulo with 7% and Rio Grande do Sul also with 7%) held 73% of the nation's total slave population. These were followed by Pernambuco (with 6%) and Alagoas (with 4%). Among the remaining 13 provinces none individually had even 3%.Most slaves worked as plantation laborers. Relatively few Brazilians owned slaves and most small and medium-sized farms employed free workers. Slaves could be found scattered throughout society in other capacities: some were used as house servants, farmers, miners, prostitutes, gardeners and in many other roles. Many emancipated slaves went on to acquire slaves and there were even cases of slaves who had their own slaves. While slaves were usually black or mulatto there were reported cases of slaves who appeared to be of European descent—the product of generations of inter-ethnic sexual relations between male slave owners and their female mulatto slaves. Even the harshest slave owners adhered to a long-established practice of selling slaves along with their families, taking care not to separate individuals. Slaves were regarded by law as properties. The ones who were freed immediately became citizens with all civil rights guaranteed—the only exception being that, until 1881, freed slaves were barred from voting in elections, although their children and descendants could vote.
answer:
What were used as used as house servants, farmers, miners, prostitutes, and gardeners?
