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: Groups share a fundamental kinship with the notion of symmetry. For example, a symmetry group encodes symmetry features of a geometrical object: the group consists of the set of transformations that leave the object unchanged and the operation of combining two such transformations by performing one after the other. Lie groups are the symmetry groups used in the Standard Model of particle physics; Point groups are used to help understand symmetry phenomena in molecular chemistry; and Poincare groups can express the physical symmetry underlying special relativity.
[EX A]: What encodes a symmetry group?

[EX Q]: Passage: Noteworthy Irish mandolinists include Andy Irvine (who, like Johnny Moynihan, almost always tunes the top E down to D, to achieve an open tuning of GDAD), Paul Brady, Mick Moloney, Paul Kelly and Claudine Langille. John Sheahan and the late Barney McKenna, respectively fiddle player and tenor banjo player with The Dubliners, are also accomplished Irish mandolin players. The instruments used are either flat-backed, oval hole examples as described above (made by UK luthier Roger Bucknall of Fylde Guitars), or carved-top, oval hole instruments with arched back (made by Stefan Sobell in Northumberland). The Irish guitarist Rory Gallagher often played the mandolin on stage, and he most famously used it in the song "Going To My Hometown."
[EX A]: Who are some of the famous Italian Mandolinists?

[EX Q]: Passage: At the inception of the Premier League in 199293, just eleven players named in the starting line-ups for the first round of matches hailed from outside of the United Kingdom or Ireland. By 200001, the number of foreign players participating in the Premier League was 36 per cent of the total. In the 200405 season the figure had increased to 45 per cent. On 26 December 1999, Chelsea became the first Premier League side to field an entirely foreign starting line-up, and on 14 February 2005 Arsenal were the first to name a completely foreign 16-man squad for a match. By 2009, under 40% of the players in the Premier League were English.
[EX A]:
How many players were from the UK or Ireland when the Premier League was created?
