Definition: 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.
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.
Output:
What is the first name of the person who started their own sausage factory?
