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: In cases where the criminalized behavior is pure speech, civil disobedience can consist simply of engaging in the forbidden speech. An example would be WBAI's broadcasting the track "Filthy Words" from a George Carlin comedy album, which eventually led to the 1978 Supreme Court case of FCC v. Pacifica Foundation. Threatening government officials is another classic way of expressing defiance toward the government and unwillingness to stand for its policies. For example, Joseph Haas was arrested for allegedly sending an email to the Lebanon, New Hampshire city councilors stating, "Wise up or die."
Example Output: What did George Carlin send to the city council in New Hampshire?

Example Input: Passage: The other Ancient Greek dialects, Ionic, Doric, Aeolic, and Arcadocypriot, likely had the same three-way distinction at one point, but Doric seems to have had a fricative in place of /tʰ/ in the Classical period, and the Ionic and Aeolic dialects sometimes lost aspiration (psilosis).
Example Output: What ancient dialects had the same two-way distinction at one point?

Example Input: Passage: Norman architecture typically stands out as a new stage in the architectural history of the regions they subdued. They spread a unique Romanesque idiom to England and Italy, and the encastellation of these regions with keeps in their north French style fundamentally altered the military landscape. Their style was characterised by rounded arches, particularly over windows and doorways, and massive proportions.
Example Output:
What type of arch did the Normans invent?
