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: 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.

Passage: An Army-OSRD council on 25 June 1942 decided to build a pilot plant for plutonium production in Red Gate Woods southwest of Chicago. In July, Nichols arranged for a lease of 1,025 acres (415 ha) from the Cook County Forest Preserve District, and Captain James F. Grafton was appointed Chicago area engineer. It soon became apparent that the scale of operations was too great for the area, and it was decided to build the plant at Oak Ridge, and keep a research and testing facility in Chicago.Delays in establishing the plant in Red Gate Woods led Compton to authorize the Metallurgical Laboratory to construct the first nuclear reactor beneath the bleachers of Stagg Field at the University of Chicago. The reactor required an enormous amount of graphite blocks and uranium pellets. At the time, there was a limited source of pure uranium. Frank Spedding of Iowa State University were able to produce only two short tons of pure uranium. Additional three short tons of uranium metal was supplied by Westinghouse Lamp Plant which was produced in a rush with makeshift process. A large square balloon was constructed by Goodyear Tire to encase the reactor. On 2 December 1942, a team led by Enrico Fermi initiated the first artificial self-sustaining nuclear chain reaction in an experimental reactor known as Chicago Pile-1. The point at which a reaction becomes self-sustaining became known as "going critical". Compton reported the success to Conant in Washington, D.C., by a coded phone call, saying, "The Italian navigator [Fermi] has just landed in the new world."In January 1943, Grafton's successor, Major Arthur V. Peterson, ordered Chicago Pile-1 dismantled and reassembled at Red Gate Woods, as he regarded the operation of a reactor as too hazardous for a densely populated area. At the Argonne site, Chicago Pile-3, the first heavy water reactor, went critical on 15 May 1944. After the war, the operations that remained at Red Gate moved to the new site of the Argonne National Laboratory about 6 miles (9.7 km) away.

Passage: Bush's son, Bertie, featured prominently in the 2014 concert Before the Dawn. She previously had a long-term relationship with bassist and engineer Del Palmer from the late 1970s to the early 1990s.Bush is a former resident of Eltham, southeast London. In the 1990s, she moved to a canalside residence in Sulhamstead, Berkshire, and moved to Devon in 2004. Bush is a vegetarian. Raised a Roman Catholic, she said in 1999:
...I would never say I was a strict follower of Roman Catholic belief, but a lot of [powerful, beautiful and passionate images are in there.] There's a lot of suffering in Roman Catholicism. I think I'm looking for not necessarily religion, but ways of helping myself to become more understanding, more complete, a happier person [...] But I really don't think I've found a niche.
The length of time between albums has led to rumours concerning Bush's health or appearance. In 2011, she told BBC Radio 4 that the amount of time between albums was stressful: "It's very frustrating the albums take as long as they do ... I wish there weren't such big gaps between them". In the same interview, she denied that she was a perfectionist, saying: "I think it's important that things are flawed ... That's what makes a piece of art interesting sometimes – the bit that's wrong or the mistake you've made that's led onto an idea you wouldn't have had otherwise." She reiterated her prioritisation of her family life.Bush's nephew, Raven Bush is violinist in the English indie band Syd Arthur.In 2016, Maclean's reported that Bush supported Theresa May, the Conservative Prime Minister of the United Kingdom. It quoted Bush as saying: "I actually really like her and think she’s wonderful. I think it’s the best thing that’s happened to us in a long time ... It is great to have a woman in charge of the country. She’s very sensible and I think that’s a good thing at this point in time." In 2019, Bush published a statement on her website saying she had been quoted out of context and did not support the Conservative Party. She wrote: "My response to the interviewer was not meant to be political but rather was in the defence of women in power ... I said that we had a woman in charge of our country, and that I felt it was a good thing to have women in power … it could make it seem like I am a Tory supporter which I want to make clear I am not.".
