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: Cork is home to one of Ireland's main national newspapers, the Irish Examiner (formerly the Cork Examiner). It also prints the Evening Echo, which for decades has been connected to the Echo Boys, who were poor and often homeless children who sold the newspaper. Today, the shouts of the vendors selling the Echo can still be heard in various parts of the city centre. One of the biggest free newspapers in the city is the Cork Independent. The city's University publishes the UCC Express and Motley magazine.
Example Output: What did the Irish Examiner change its name to?

Example Input: Passage: Rail transport in Victoria is provided by several private and public railway operators who operate over government-owned lines. Major operators include: Metro Trains Melbourne which runs an extensive, electrified, passenger system throughout Melbourne and suburbs; V/Line which is now owned by the Victorian Government, operates a concentrated service to major regional centres, as well as long distance services on other lines; Pacific National, CFCL Australia which operate freight services; Great Southern Rail which operates The Overland Melbourne—Adelaide; and NSW TrainLink which operates XPTs Melbourne—Sydney.
Example Output: Who owns the rail cars in Victoria?

Example Input: Passage: Criticism of the War on Terror addresses the issues, morality, efficiency, economics, and other questions surrounding the War on Terror and made against the phrase itself, calling it a misnomer. The notion of a "war" against "terrorism" has proven highly contentious, with critics charging that it has been exploited by participating governments to pursue long-standing policy/military objectives, reduce civil liberties, and infringe upon human rights. It is argued that the term war is not appropriate in this context (as in War on Drugs), since there is no identifiable enemy, and that it is unlikely international terrorism can be brought to an end by military means.
Example Output:
What is another name for War on Drugs?
