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: In its focus on the Caliphate, the party takes a different view of Muslim history than some other Islamists such as Muhammad Qutb. HT sees Islam's pivotal turning point as occurring not with the death of Ali, or one of the other four rightly guided Caliphs in the 7th century, but with the abolition of the Ottoman Caliphate in 1924. This is believed to have ended the true Islamic system, something for which it blames "the disbelieving (Kafir) colonial powers" working through Turkish modernist Mustafa Kemal Atatürk.
[EX A]: What's the party's take on Muslim present?

[EX Q]: Passage: A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was glaciated throughout the period, though it is uncertain if the ice sheets were a holdover from the Devonian or not. These conditions apparently had little effect in the deep tropics, where lush coal swamps flourished within 30 degrees of the northernmost glaciers. A mid-Carboniferous drop in sea-level precipitated a major marine extinction, one that hit crinoids and ammonites especially hard. This sea-level drop and the associated unconformity in North America separate the Mississippian Period from the Pennsylvanian period.
[EX A]: What dropped world wide at the begining of the Devonian?

[EX Q]: Passage: The Council does not have executive powers but meets biannually to discuss issues of mutual importance. Similarly, the Parliamentary Assembly has no legislative powers but investigates and collects witness evidence from the public on matters of mutual concern to its members. Reports on its findings are presented to the Governments of Ireland and the United Kingdom. During the February 2008 meeting of the British–Irish Council, it was agreed to set up a standing secretariat that would serve as a permanent 'civil service' for the Council. Leading on from developments in the British–Irish Council, the chair of the British–Irish Inter-Parliamentary Assembly, Niall Blaney, has suggested that the body should shadow the British–Irish Council's work.
[EX A]:
The council has executive powers and meets how often?
