Detailed Instructions: 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.
See one example below:
Problem: Passage: In 1763, Spain traded Florida to the Kingdom of Great Britain for control of Havana, Cuba, which had been captured by the British during the Seven Years' War. It was part of a large expansion of British territory following the country's victory in the Seven Years' War. Almost the entire Spanish population left, taking along most of the remaining indigenous population to Cuba. The British soon constructed the King's Road connecting St. Augustine to Georgia. The road crossed the St. Johns River at a narrow point, which the Seminole called Wacca Pilatka and the British named "Cow Ford", both names ostensibly reflecting the fact that cattle were brought across the river there.
Solution: Who owned Cuba after the Eight Years War?
Explanation: This question appears to be relevant to the passage as both involves words such as 'Cuba' and 'War' which also exist in the passage. The passage mentions that "after the war, almost the entire Spanish population left, taking along most of the remaining indigenous population to Cuba". This information is not sufficient to conclude that which country owned cuba.

Problem: Passage: Rugby league is mostly played by Samoans living in New Zealand and Australia,[citation needed] with Samoa reaching the quarter finals of the 2013 Rugby League World Cup made of players playing in the NRL, Super League and domestic players. Many Samoans and New Zealanders or Australians of Samoan descent play in the Super League and National Leagues in Britain. Francis Meli, Ta'ane Lavulavu of Workington Town, Maurie Fa'asavalu of St Helens and David Fatialofa of Whitehaven and Setima Sa who signed with London Irish rugby club. Other noteworthy players from NZ and Australia have represented the Samoan National team. The 2011 domestic Samoan rugby league competition contained 10 teams with plans to expand to 12 in 2012.
Solution:
What is mostly played by Australians living in New Zealand?
