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: The National Incident Based Reporting System (NIBRS) crime statistics system aims to address limitations inherent in UCR data. The system is used by law enforcement agencies in the United States for collecting and reporting data on crimes. Local, state, and federal agencies generate NIBRS data from their records management systems. Data is collected on every incident and arrest in the Group A offense category. The Group A offenses are 46 specific crimes grouped in 22 offense categories. Specific facts about these offenses are gathered and reported in the NIBRS system. In addition to the Group A offenses, eleven Group B offenses are reported with only the arrest information. The NIBRS system is in greater detail than the summary-based UCR system. As of 2004, 5,271 law enforcement agencies submitted NIBRS data. That amount represents 20% of the United States population and 16% of the crime statistics data collected by the FBI.
Example Output: What system do Canadian law enforcement agencies use?

Example Input: Passage: Many early immigrant groups traveled to America to worship freely, particularly after the English Civil War and religious conflict in France and Germany. They included nonconformists like the Puritans, who were Protestant Christians fleeing religious persecution from the Anglican King of England. Despite a common background, the groups' views on religious toleration were mixed. While some such as Roger Williams of Rhode Island and William Penn of Pennsylvania ensured the protection of religious minorities within their colonies, others like the Plymouth Colony and Massachusetts Bay Colony had established churches. The Dutch colony of New Netherland established the Dutch Reformed Church and outlawed all other worship, though enforcement was sparse. Religious conformity was desired partly for financial reasons: the established Church was responsible for poverty relief, putting dissenting churches at a significant disadvantage.
Example Output: What was one of the reason late immigrant groups came to America?

Example Input: Passage: People can be exposed to asphalt in the workplace by breathing in fumes or skin absorption. The National Institute for Occupational Safety and Health (NIOSH) has set a Recommended exposure limit (REL) of 5 mg/m3 over a 15-minute period. Asphalt is basically an inert material that must be heated or diluted to a point where it becomes workable for the production of materials for paving, roofing, and other applications. In examining the potential health hazards associated with asphalt, the International Agency for Research on Cancer (IARC) determined that it is the application parameters, predominantly temperature, that effect occupational exposure and the potential bioavailable carcinogenic hazard/risk of the asphalt emissions. In particular, temperatures greater than 199 °C (390 °F), were shown to produce a greater exposure risk than when asphalt was heated to lower temperatures, such as those typically used in asphalt pavement mix production and placement.
Example Output:
How can people be exposed to low temperatures while at work?
