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 centrality of the "separation" concept to the Religion Clauses of the Constitution was made explicit in Everson v. Board of Education, 330 U.S. 1 (1947), a case dealing with a New Jersey law that allowed government funds to pay for transportation of students to both public and Catholic schools. This was the first case in which the court applied the Establishment Clause to the laws of a state, having interpreted the due process clause of the Fourteenth Amendment as applying the Bill of Rights to the states as well as the federal legislature. Citing Jefferson, the court concluded that "The First Amendment has erected a wall between church and state. That wall must be kept high and impregnable. We could not approve the slightest breach."
Example Output: When was the centrality of the "separation" concept to the Religion Clauses of the Constitution not made explicit?

Example Input: Passage: Contract law covers obligations established by agreement (express or implied) between private parties. Generally, contract law in transactions involving the sale of goods has become highly standardized nationwide as a result of the widespread adoption of the Uniform Commercial Code. However, there is still significant diversity in the interpretation of other kinds of contracts, depending upon the extent to which a given state has codified its common law of contracts or adopted portions of the Restatement (Second) of Contracts.
Example Output: What does contract law not cover?

Example Input: Passage: After the end of the late Middle Ages period, the Renaissance would spread unevenly over continental Europe from the southern European region. The intellectual transformation of the Renaissance is viewed as a bridge between the Middle Ages and the Modern era. Europeans would later begin an era of world discovery. Combined with the influx of classical ideas was the invention of printing which facilitated dissemination of the printed word and democratized learning. These two things would lead to the Protestant Reformation. Europeans also discovered new trading routes, as was the case with Columbus’s travel to the Americas in 1492, and Vasco da Gama’s circumnavigation of Africa and India in 1498. Their discoveries strengthened the economy and power of European nations.
Example Output:
Along with the invention of printing, and the associated dissemination of the printed word, what other factor is not believed to have led to the Protestant Reformation?
