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 first union was built on campus in 1926 as a campus community center. The unions are still the "living rooms" of campus today and include three locations – the Kansas Union and Burge Union at the Lawrence Campus and Jayhawk Central at the Edwards Campus. The KU Memorial Unions Corporation manages the KU Bookstore (with seven locations). The KU Bookstore is the official bookstore of KU. The Corporation also includes KU Dining Services, with more than 20 campus locations, including The Market (inside the Kansas Union) and The Underground (located in Wescoe Hall). The KU Bookstore and KU Dining Services are not-for-profit, with proceeds going back to support student programs, such as Student Union Activities.
Example Output: When was KU's last student union constructed?

Example Input: Passage: Some multiracial individuals feel marginalized by U.S. society. For example, when applying to schools or for a job, or when taking standardized tests, Americans are sometimes asked to check boxes corresponding to race or ethnicity. Typically, about five race choices are given, with the instruction to "check only one." While some surveys offer an "other" box, this choice groups together individuals of many different multiracial types (ex: European Americans/African-Americans are grouped with Asian/Native American Indians).
Example Output: Who feels marginalized by Canadian society?

Example Input: Passage: England failed to qualify for the World Cup in 1974, 1978 and 1994. The team's earliest exit in the competition itself was its elimination in the first round in 1950, 1958 and most recently in the 2014 FIFA World Cup, after being defeated in both their opening two matches for the first time, versus Italy and Uruguay in Group D. In 1950, four teams remained after the first round, in 1958 eight teams remained and in 2014 sixteen teams remained. In 2010, England suffered its most resounding World Cup defeat (4–1 to Germany) in the Round of 16, after drawing with the United States and Algeria and defeating Slovenia 1–0 in the group stage.
Example Output:
Where was the 1974 World Cup held?
