This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Example Input: Passage: During the early 20th century, northerners were attracted to the city, and Miami prospered during the 1920s with an increase in population and infrastructure. The legacy of Jim Crow was embedded in these developments. Miami's chief of police, H. Leslie Quigg, did not hide the fact that he, like many other white Miami police officers, was a member of the Ku Klux Klan. Unsurprisingly, these officers enforced social codes far beyond the written law. Quigg, for example, "personally and publicly beat a colored bellboy to death for speaking directly to a white woman."
Example Output: Who was a unnotable chief of the Miami police?

Example Input: Passage: Sichuan consists of two geographically very distinct parts. The eastern part of the province is mostly within the fertile Sichuan basin (which is shared by Sichuan with Chongqing Municipality). The western Sichuan consists of the numerous mountain ranges forming the easternmost part of the Qinghai-Tibet Plateau, which are known generically as Hengduan Mountains. One of these ranges, Daxue Mountains, contains the highest point of the province Gongga Shan, at 7,556 metres (24,790 ft) above sea level.
Example Output: What province has similar eastern and western parts?

Example Input: Passage: The ritual form on which the Grand Orient of France was based was abolished in England in the events leading to the formation of the United Grand Lodge of England in 1813. However the two jurisdictions continued in amity (mutual recognition) until events of the 1860s and 1870s drove a seemingly permanent wedge between them. In 1868 the Supreme Council of the Ancient and Accepted Scottish Rite of the State of Louisiana appeared in the jurisdiction of the Grand Lodge of Louisiana, recognised by the Grand Orient de France, but regarded by the older body as an invasion of their jurisdiction. The new Scottish rite body admitted blacks, and the resolution of the Grand Orient the following year that neither colour, race, nor religion could disqualify a man from Masonry prompted the Grand Lodge to withdraw recognition, and it persuaded other American Grand Lodges to do the same.
Example Output:
When was the United Grand Lodge of England demolished?
