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: Selenizza is a naturally occurring solid hydrocarbon bitumen found in the native asphalt deposit of Selenice, in Albania, the only European asphalt mine still in use. The rock asphalt is found in the form of veins, filling cracks in a more or less horizontal direction. The bitumen content varies from 83% to 92% (soluble in carbon disulphide), with a penetration value near to zero and a softening point (ring & ball) around 120 °C. The insoluble matter, consisting mainly of silica ore, ranges from 8% to 17%.
Example Output: The soluble matter consists mainly of silica ore and ranges from what percentage?

Example Input: 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 Poincaré groups can express the physical symmetry underlying special relativity.
Example Output: What encodes a symmetry group?

Example Input: Passage: The phrase "in whole or in part" has been subject to much discussion by scholars of international humanitarian law. The International Criminal Tribunal for the Former Yugoslavia found in Prosecutor v. Radislav Krstic – Trial Chamber I – Judgment – IT-98-33 (2001) ICTY8 (2 August 2001) that Genocide had been committed. In Prosecutor v. Radislav Krstic – Appeals Chamber – Judgment – IT-98-33 (2004) ICTY 7 (19 April 2004) paragraphs 8, 9, 10, and 11 addressed the issue of in part and found that "the part must be a substantial part of that group. The aim of the Genocide Convention is to prevent the intentional destruction of entire human groups, and the part targeted must be significant enough to have an impact on the group as a whole." The Appeals Chamber goes into details of other cases and the opinions of respected commentators on the Genocide Convention to explain how they came to this conclusion.
Example Output:
Which phrase is especially contentious within human groups?
