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 Wayback Machine is a digital archive of the World Wide Web and other information on the Internet created by the Internet Archive, a nonprofit organization, based in San Francisco, California, United States. It was set up by Brewster Kahle and Bruce Gilliat, and is maintained with content from Alexa Internet. The service enables users to see archived versions of web pages across time, which the archive calls a "three dimensional index."
Example Output: Where does the information stored on the Internet Archive come from?

Example Input: Passage: Unlike the Baroque style that it replaced, which was mostly used for palaces and churches, and had little representation in the British colonies, simpler Georgian styles were widely used by the upper and middle classes. Perhaps the best remaining house is the pristine Hammond-Harwood House (1774) in Annapolis, Maryland, designed by the colonial architect William Buckland and modelled on the Villa Pisani at Montagnana, Italy as depicted in Andrea Palladio's I quattro libri dell'architettura ("Four Books of Architecture").
Example Output: What style was widely represented in British colonies?

Example Input: Passage: On September 11, 2001, 53 Army civilians (47 employees and six contractors) and 22 soldiers were among the 125 victims killed in the Pentagon in a terrorist attack when American Airlines Flight 77 commandeered by five Al-Qaeda hijackers slammed into the western side of the building, as part of the September 11 attacks. Lieutenant General Timothy Maude was the highest-ranking military official killed at the Pentagon, and the most senior U.S. Army officer killed by foreign action since the death of Lieutenant General Simon B. Buckner, Jr. on June 18, 1945, in the Battle of Okinawa during World War II.
Example Output:
How many victims were killed in the attack of the White House?
