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 Input:
Passage: The strength of the Viking influence on Old English appears from the fact that the indispensable elements of the language - pronouns, modals, comparatives, pronominal adverbs (like "hence" and "together"), conjunctions and prepositions - show the most marked Danish influence; the best evidence of Scandinavian influence appears in the extensive word borrowings for, as Jespersen indicates, no texts exist in either Scandinavia or in Northern England from this time to give certain evidence of an influence on syntax. The change to Old English from Old Norse was substantive, pervasive, and of a democratic character. Old Norse and Old English resembled each other closely like cousins and with some words in common, they roughly understood each other; in time the inflections melted away and the analytic pattern emerged. It is most “important to recognize that in many words the English and Scandinavian language differed chiefly in their inflectional elements. The body of the word was so nearly the same in the two languages that only the endings would put obstacles in the way of mutual understanding. In the mixed population which existed in the Danelaw these endings must have led to much confusion, tending gradually to become obscured and finally lost.” This blending of peoples and languages happily resulted in “simplifying English grammar.”

Ex Output:
What language was influenced by English as a result of Viking invasions?

Passage: The gastronomic symbol of the région is undoubtedly the Choucroute, a local variety of Sauerkraut. The word Sauerkraut in Alsatian has the form sûrkrût, same as in other southwestern German dialects, and means "sour cabbage" as its Standard German equivalent. This word was included into the French language as choucroute. To make it, the cabbage is finely shredded, layered with salt and juniper and left to ferment in wooden barrels. Sauerkraut can be served with poultry, pork, sausage or even fish. Traditionally it is served with Strasbourg sausage or frankfurters, bacon, smoked pork or smoked Morteau or Montbéliard sausages, or a selection of other pork products. Served alongside are often roasted or steamed potatoes or dumplings.

Ex Output:
What word does Choucroute come from?


Ex Input:
Passage: Jonassohn and Björnson postulate that the major reason why no single generally accepted genocide definition has emerged is because academics have adjusted their focus to emphasise different periods and have found it expedient to use slightly different definitions to help them interpret events. For example, Frank Chalk and Kurt Jonassohn studied the whole of human history, while Leo Kuper and R. J. Rummel in their more recent works concentrated on the 20th century, and Helen Fein, Barbara Harff and Ted Gurr have looked at post World War II events. Jonassohn and Björnson are critical of some of these studies, arguing that they are too expansive, and conclude that the academic discipline of genocide studies is too young to have a canon of work on which to build an academic paradigm.

Ex Output:

What two writers examined the lack of an accepted and singular definition for academics?
