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.

Input: Consider Input: Passage: Following their basic and advanced training at the individual-level, soldiers may choose to continue their training and apply for an "additional skill identifier" (ASI). The ASI allows the army to take a wide ranging MOS and focus it into a more specific MOS. For example, a combat medic, whose duties are to provide pre-hospital emergency treatment, may receive ASI training to become a cardiovascular specialist, a dialysis specialist, or even a licensed practical nurse. For commissioned officers, ASI training includes pre-commissioning training either at USMA, or via ROTC, or by completing OCS. After commissioning, officers undergo branch specific training at the Basic Officer Leaders Course, (formerly called Officer Basic Course), which varies in time and location according their future assignments. Further career development is available through the Army Correspondence Course Program.

Output: What does ISI stand for?

Input: Consider Input: Passage: The Samoan word for dance is siva with unique gentle movements of the body in time to music and which tells a story, although the Samoan male dances can be more physical and snappy. The sasa is also a traditional dance where rows of dancers perform rapid synchronised movements in time to the rhythm of wooden drums (pate) or rolled mats. Another dance performed by males is called the fa'ataupati or the slap dance, creating rhythmic sounds by slapping different parts of the body. This is believed to have been derived from slapping insects on the body.

Output: What is the Samoan word for rhythm?

Input: Consider Input: Passage: Sociologist Jake Rosenfield of the University of Washington asserts that the decline of organized labor in the United States has played a more significant role in expanding the income gap than technological changes and globalization, which were also experienced by other industrialized nations that didn't experience steep surges in inequality. He points out that nations with high rates of unionization, particularly in Scandinavia, have very low levels of inequality, and concludes "the historical pattern is clear; the cross-national pattern is clear: high inequality goes hand-in-hand with weak labor movements and vice-versa."
Output: What country has low income inequality and low presence of unions?
