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: Dominic's search for a close relationship with God was determined and unceasing. He rarely spoke, so little of his interior life is known. What is known about it comes from accounts written by people near to him. St. Cecilia remembered him as cheerful, charitable and full of unceasing vigor. From a number of accounts, singing was apparently one of Dominic's great delights. Dominic practiced self-scourging and would mortify himself as he prayed alone in the chapel at night for 'poor sinners.' He owned a single habit, refused to carry money, and would allow no one to serve him.
Example Output: What did Dominic not struggle with?

Example Input: Passage: Bermuda's modern black population contains more than one demographic group. Although the number of residents born in Africa is very small, it has tripled between 2000 and 2010 (this group also includes non-blacks). The majority of blacks in Bermuda can be termed "Bermudian blacks", whose ancestry dates back centuries between the 17th century and the end of slavery in 1834, Bermuda's black population was self-sustaining, with its growth resulting largely from natural expansion. This contrasts to the enslaved blacks of the plantation colonies, who were subjected to conditions so harsh as to drop their birth rate below the death rate, and slaveholders in the United States and the West Indies found it necessary to continue importing more enslaved blacks from Africa until the end of slavery (the same had been true for the Native Americans that the Africans had replaced on the New World plantations). The indigenous populations of many West Indian islands, and much of the South-East of what is now the United States that had survived the 16th- and 17th-century epidemics of European-introduced diseases then became the victims of large-scale slave raiding, with much of the region completely depopulated. When the supply of indigenous slaves ran out, the slaveholders looked to Africa). The ancestry of Bermuda's black population is distinguished from that of the British West Indian black population in two ways: firstly, the higher degree of European and Native American admixture; secondly, the source of the African ancestry.
Example Output: What modern population contains one demographic group?

Example Input: Passage: On 20 June 1794, Burke received a vote of thanks from the Commons for his services in the Hastings Trial and he immediately resigned his seat, being replaced by his son Richard. A tragic blow fell upon Burke with the loss of Richard in August 1794, to whom he was tenderly attached, and in whom he saw signs of promise, which were not patent to others and which, in fact, appear to have been non-existent (though this view may have rather reflected the fact that Richard Burke had worked successfully in the early battle for Catholic emancipation). King George III, whose favour he had gained by his attitude on the French Revolution, wished to create him Earl of Beaconsfield, but the death of his son deprived the opportunity of such an honour and all its attractions, so the only award he would accept was a pension of £2,500. Even this modest reward was attacked by the Duke of Bedford and the Earl of Lauderdale, to whom Burke replied in his Letter to a Noble Lord (1796): "It cannot at this time be too often repeated; line upon line; precept upon precept; until it comes into the currency of a proverb, To innovate is not to reform". He argued that he was rewarded on merit, but the Duke of Bedford received his rewards from inheritance alone, his ancestor being the original pensioner: "Mine was from a mild and benevolent sovereign; his from Henry the Eighth". Burke also hinted at what would happen to such people if their revolutionary ideas were implemented, and included a description of the British constitution:
Example Output:
When did Burke submit a vote of thanks?
