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.

Ex Input:
Passage: Doug is a flight instructor and owner of a pilot school. He, his wife Abby and their two daughters, Lindsay and Amanda face serious financial problems, as they are near financial ruin, and need $300,000 to expand the pilot school. 
Doug has to work hard and has hardly any time for his family, even arriving at home late on Christmas Eve. During the meal Doug receives a phone call from a lawyer who informs him that his parents are not his biological parents, but that he was adopted by an open adoption by them. The lawyer asks him to come to a meeting, where problems concerning his biological father are to be discussed.
The lawyer introduces him to his half sister, Delilah, who was disowned from their father. Her only interest is to have her father judged unfit in order to sell his property. The lawyer asks whether they want to look after the property and their father. If they would, they would also take responsibility of him. Doug decides to do so without asking Abby.

Ex Output:
What are the first names of the family that is facing serious financial problems?

Passage: When Thriller and "Billie Jean" were searching to reach their market demographic, MTV and cable TV had a smaller market share than the much larger reach of broadcast television stations in the United States. A national broadcast TV audience on ABC, NBC and CBS affiliate stations, as well as major independent TV stations, was desired by CBS/Epic Records to promote Thriller. The national broadcast TV premiere of the Thriller album's first video, "Billie Jean", was during the week of Halloween in October 1984 and was the idea of Video Concert Hall executive producers Charles Henderson and Jerry Crowe. Video Concert Hall, the first nationwide music video TV network, taped the one-hour special in Hollywood and Atlanta, where the TV studios of Video Concert Hall were located. The Thriller TV special was hosted by Thriller video co-star Vincent Price, distributed by Henderson-Crowe Syndications, Inc. and aired in the top 20 TV markets and much of the United States, including TV stations WNEW (New York), WFLD (Chicago), KTTV (Los Angeles), WPLG (Miami), WQTV (Boston) and WXIA (Atlanta), for a total of 150 TV stations.From the moment Thriller was released, it set the standard for the music industry: artists, record labels, producers, marketers and even choreographers. The music video was ahead of its time and it is considered a monumental one—not only in Jackson's career, but also in the history of pop music. Epic Records' approach to creating a song and video that would appeal to the mass market ended up influencing the way that professionals now market and release their songs. John Landis' production of a mini-movie, rather than the usual short music video, would raise the bar for other directors and producers.

Ex Output:
What music video was ahead of its time and it is considered a monumental one in the history of pop music?

Passage: The second major American company to set up a manufacturing base in Trafford Park was the Ford Motor Company, in 1911. Initially Ford used its factory as an assembly plant for the Model T, although other vehicles were assembled there in later years, before moving to a new factory at Dagenham, Essex, in 1931. By 1915, 100 American companies had moved into the park, peaking at more than 200 by 1933. When the cotton industry began to decline in the early 20th century, Trafford Park and the Manchester Ship Canal helped Manchester – and to a lesser extent the rest of south Lancashire – to weather the economic depression from which the rest of Lancashire suffered. During the First World War the park was used for the manufacture of munitions, chemicals and other materiel. Most firms at Trafford Park succeeded in avoiding bankruptcy during the Great Depression, unlike the rest of Lancashire. Ford moved to Dagenham in 1931, but returned temporarily to Trafford Park during the Second World War.Metropolitan Vickers set up Manchester's and one of the UK's first radio stations at their factory in 1921. The station's first broadcast took place on 17 May 1922. In October that year the company was one of six who formed the British Broadcasting Company (BBC), which started broadcasting from the Metrovicks studio under the call sign 2ZY on 15 November 1922. Much of the station's content was musical, but news, plays, and children's programmes were also transmitted. Conditions in the small 30-by-16-foot (9.1 m × 4.9 m) studio were cramped, and the BBC moved the station to larger premises outside the park in 1923.

Ex Output:

Where had 100 American companies moved to by 1915?
