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: In free-range husbandry, the birds can roam freely outdoors for at least part of the day. Often, this is in large enclosures, but the birds have access to natural conditions and can exhibit their normal behaviours. A more intensive system is yarding, in which the birds have access to a fenced yard and poultry house at a higher stocking rate. Poultry can also be kept in a barn system, with no access to the open air, but with the ability to move around freely inside the building. The most intensive system for egg-laying chickens is battery cages, often set in multiple tiers. In these, several birds share a small cage which restricts their ability to move around and behave in a normal manner. The eggs are laid on the floor of the cage and roll into troughs outside for ease of collection. Battery cages for hens have been illegal in the EU since January 1, 2012.
Example Output: What is the benefit to chickens of being in a caged location?

Example Input: Passage: The legendary religious zeal of the Normans was exercised in religious wars long before the First Crusade carved out a Norman principality in Antioch. They were major foreign participants in the Reconquista in Iberia. In 1018, Roger de Tosny travelled to the Iberian Peninsula to carve out a state for himself from Moorish lands, but failed. In 1064, during the War of Barbastro, William of Montreuil led the papal army and took a huge booty.
Example Output: Where did the Normans carve out a principality before the First Crusade?

Example Input: Passage: When the news arrived in England it caused an outcry. In response, a combined bounty of £1,000 was offered for Every's capture by the Privy Council and East India Company, leading to the first worldwide manhunt in recorded history. The plunder of Aurangzeb's treasure ship had serious consequences for the English East India Company. The furious Mughal Emperor Aurangzeb ordered Sidi Yaqub and Nawab Daud Khan to attack and close four of the company's factories in India and imprison their officers, who were almost lynched by a mob of angry Mughals, blaming them for their countryman's depredations, and threatened to put an end to all English trading in India. To appease Emperor Aurangzeb and particularly his Grand Vizier Asad Khan, Parliament exempted Every from all of the Acts of Grace (pardons) and amnesties it would subsequently issue to other pirates.
Example Output:
Who caused the first worldwide witch-hunt?
