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: When revolutionary France declared war on Great Britain in 1793, the United States sought to remain neutral, but the Jay Treaty, which was favorable to Great Britain, angered the French government, which viewed it as a violation of the 1778 Treaty of Alliance. French privateers began to seize U.S. vessels, which led to an undeclared "Quasi-War" between the two nations. Fought at sea from 1798 to 1800, the United States won a string of victories in the Caribbean. George Washington was called out of retirement to head a "provisional army" in case of invasion by France, but President John Adams managed to negotiate a truce, in which France agreed to terminate the prior alliance and cease its attacks.
Example Output: What was the UK policy when France declared war on England in 1793?

Example Input: Passage: Infrared reflectography (fr; it; es), as called by art conservators, can be applied to paintings to reveal underlying layers in a completely non-destructive manner, in particular the underdrawing or outline drawn by the artist as a guide. This often reveals the artist's use of carbon black, which shows up well in reflectograms, as long as it has not also been used in the ground underlying the whole painting. Art conservators are looking to see whether the visible layers of paint differ from the underdrawing or layers in between such alterations are called pentimenti when made by the original artist. This is very useful information in deciding whether a painting is the prime version by the original artist or a copy, and whether it has been altered by over-enthusiastic restoration work. In general, the more pentimenti the more likely a painting is to be the prime version. It also gives useful insights into working practices.
Example Output: What painting technique is used to reveal working practices?

Example Input: Passage: Harvard has the largest university endowment in the world. As of September 2011[update], it had nearly regained the loss suffered during the 2008 recession. It was worth $32 billion in 2011, up from $28 billion in September 2010 and $26 billion in 2009. It suffered about 30% loss in 2008-09. In December 2008, Harvard announced that its endowment had lost 22% (approximately $8 billion) from July to October 2008, necessitating budget cuts. Later reports suggest the loss was actually more than double that figure, a reduction of nearly 50% of its endowment in the first four months alone. Forbes in March 2009 estimated the loss to be in the range of $12 billion. One of the most visible results of Harvard's attempt to re-balance its budget was their halting of construction of the $1.2 billion Allston Science Complex that had been scheduled to be completed by 2011, resulting in protests from local residents. As of 2012[update], Harvard University had a total financial aid reserve of $159 million for students, and a Pell Grant reserve of $4.093 million available for disbursement.
Example Output:
What amount did Harvard cut from their 2012 financial aid reserve?
