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.

[EX Q]: Passage: Despite yet another offer from the Institute for Advanced Study, Feynman rejected the Institute on the grounds that there were no teaching duties: Feynman felt that students were a source of inspiration and teaching was a diversion during uncreative spells. Because of this, the Institute for Advanced Study and Princeton University jointly offered him a package whereby he could teach at the university and also be at the institute.[citation needed] Feynman instead accepted an offer from the California Institute of Technology (Caltech)—and as he says in his book Surely You're Joking Mr. Feynman!—because a desire to live in a mild climate had firmly fixed itself in his mind while he was installing tire chains on his car in the middle of a snowstorm in Ithaca.
[EX A]: Why did Feynman decide to accept all offers from the Institute of Advanced Study?

[EX Q]: Passage: Contrary to the diffusionist theory, it appears that there was simultaneously a structural evolution towards the pointed arch, for the purpose of vaulting spaces of irregular plan, or to bring transverse vaults to the same height as diagonal vaults. This latter occurs at Durham Cathedral in the nave aisles in 1093. Pointed arches also occur extensively in Romanesque decorative blind arcading, where semi-circular arches overlap each other in a simple decorative pattern, and the points are accidental to the design.
[EX A]: Which cathedral is the twisted arch used to match the heights of transverse and diagonal vaults?

[EX Q]: Passage: The first Sky television rights agreement was worth £304 million over five seasons. The next contract, negotiated to start from the 1997–98 season, rose to £670 million over four seasons. The third contract was a £1.024 billion deal with BSkyB for the three seasons from 2001–02 to 2003–04. The league brought in £320 million from the sale of its international rights for the three-year period from 2004–05 to 2006–07. It sold the rights itself on a territory-by-territory basis. Sky's monopoly was broken from August 2006 when Setanta Sports was awarded rights to show two out of the six packages of matches available. This occurred following an insistence by the European Commission that exclusive rights should not be sold to one television company. Sky and Setanta paid a total of £1.7 billion, a two-thirds increase which took many commentators by surprise as it had been widely assumed that the value of the rights had levelled off following many years of rapid growth. Setanta also hold rights to a live 3 pm match solely for Irish viewers. The BBC has retained the rights to show highlights for the same three seasons (on Match of the Day) for £171.6 million, a 63 per cent increase on the £105 million it paid for the previous three-year period. Sky and BT have agreed to jointly pay £84.3 million for delayed television rights to 242 games (that is the right to broadcast them in full on television and over the internet) in most cases for a period of 50 hours after 10 pm on matchday. Overseas television rights fetched £625 million, nearly double the previous contract. The total raised from these deals is more than £2.7 billion, giving Premier League clubs an average media income from league games of around £40 million-a-year from 2007 to 2010.
[EX A]:
The first Sky television rights agreement was worth how much money over a six year period?
