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.

Example Input: Passage: Joseph and Mary lived with their son Joseph, Jr. and his family in a small house while theirs was being built. Mary Priestley was primarily responsible for the design of the couple's new home and her family inheritance may have helped finance it, but she died before it was completed. By 1797, Joseph's laboratory was completed—the first part of the home to be finished. It was the first laboratory that "he had designed, built, and outfitted entirely himself" and was probably the first "scientifically-equipped laboratory" in the United States. Joseph continued his scientific and scholarly work in his new laboratory, identifying carbon monoxide (which he called "heavy inflammable air"). In 1798 Joseph Jr., his wife, and their children moved into the new house with Joseph Priestley. The house also held Priestley's library, which contained about 1600 volumes by his death in 1804 and was one of the largest in America at the time. The Priestley family held Unitarian church services in the drawing room and Joseph educated a group of young men until the local Northumberland Academy that he helped found was completed.The house proper was completed in 1798, with a Mr. Jones of Northumberland employed acting as master carpenter. Built in an 18th-century Georgian style, the "balance and symmetry" of the architecture signaled "subdued elegance". The house was accented with Federalist highlights, such as "the fanlights over the doors and the balustrades on the rooftop belvedere and main staircase", marking it as distinctly American. Douglas R. McMinn, in the National Register of Historic Places nomination for the Northumberland Historic District, calls it a "mansion" that is "probably the finest example of the Federal style in the region". As William N. Richardson, the site administrator for the Joseph Priestley House in the 1990s, notes, Priestley's American home did not resemble his "high-style Georgian town house" that was destroyed in Birmingham; rather, it was "plain" and built in the "American vernacular".The house has a two-and-half story central section, which is 48 feet (14.6 m) by 43 feet (13.1 m), and two one-story wings on the north and south sides that are each 22 feet (6.7 m) by 21 feet (6.4 m). The first and second floors have a total area of 5,052 square feet (469 m²). The north wing was the laboratory and the south wing (which had an attached woodshed) was the summer kitchen. The cellar, first, and second floors of the central section are each divided into four rooms, with a central hall on the first and second floors; the first floor also has an intersecting hall that leads to the laboratory. The attic has three rooms for servants and a larger room for storage. A paint analysis done in 1994 revealed that the house had no wall paper initially and that the walls and woodwork were painted "a brilliant white".
Example Output: What is the full, modern-day name of the house with a library that contained about 1600 volumes in 1804?

Example Input: Passage: Born in Germany, Isaac Oscherwitz was a butcher who emigrated to America in the 1880s because of oppression and poverty. When he arrived in Cincinnati, he started his own sausage factory, which created jobs and a delicious product for the city's surprisingly well-populated Jewish community. But the Oscherwitzes also established their public face to the community through a family-run storefront shop, where they sold their meats and other classic Jewish delicacies. Decades later, Isaac's five sons extended the business to Chicago, which had become the center of the meat packing industry, and today the Oscherwitz family is responsible for well-known brands such as Best Kosher, Shofar, and Sinai.
This familial intimacy extends beyond the immediate family members to the way they treat everyone involved in the business, from factory workers to customers. "I don't think my husband ever felt like his customers were his customers," one woman says, "they were his friends." Another man, who took a job with the Oscherwitzes after he lost everything to the Holocaust, speaks highly of his employers. "It was such a family feeling," he explaining how warm and welcoming his coworkers have been.
The appeal of a family-owned product helped make the Oscherwitz brand popular, but fiscal success also jeopardized the family-run nature of the business. Before the swell of success, business meetings between the Oscherwitz brothers were a literal yelling contest, where arguments were won by the most powerful voice and, despite all the screaming, everyone left on good terms. But a big business couldn't run in the same way. The documentary shares the Oscherwitzes' inside struggles to keep their booming business family-run and shows the effects on everyone when they were bought out by a subsidiary of the Sara Lee Corporation.
Example Output: What is the first name of the person who started their own sausage factory?

Example Input: Passage: Right before Berk's traditional winter holiday of Snoggletog, all the dragons of Berk unexpectedly depart, leaving everyone distraught - except for Toothless, who cannot fly by himself. Out of compassion, Hiccup builds him a new automatic prosthesis allowing him independent flight, thus gifting him his freedom; he then flies off too.
Three days later, Meatlug, Fishlegs's dragon whom he had secretly kept chained, escapes, inadvertently taking Hiccup with him. Meatlug flies to an island with hot springs, where all the dragons (except Toothless, whom is nowhere to be found) have been hatching their eggs. Meanwhile, on Berk, Astrid and the other youth discover dragon eggs in Meatlug's nest, which they scatter around Berk in hopes of lifting the villagers' spirits; this plan backfires because dragon eggs hatch explosively (normally underwater), devastating Berk.
On the dragons' island, Hiccup meets Stormfly (Astrid's dragon) and Hookfang (Snotlout's dragon) and their newly-hatched babies; in asking for a ride home, he inadvertently triggers the dragons' return migration. He quickly decides to use a nearby wrecked ship to carry the baby dragons who cannot yet fly all the way back to Berk. The Berkians are overjoyed at their dragons' return and the new babies; yet, Hiccup is still distraught at Toothless's absence. During the ensuing Snoggletog celebration, Toothless returns with Hiccup's lost helmet, which he had dropped into the sea earlier; the two enjoy a heartfelt reunion.
The next day, Toothless destroys his new tail, begging Hiccup to put the old tailfin on him and fly with him by controlling his fin manually as opposed to merely on him; in doing so, he gives Hiccup a "better gift" - his friendship and companionship.
Example Output:
What is on the island where Hiccup meets Stormfly and Hookfang?
