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: Red hair varies from a deep burgundy through burnt orange to bright copper. It is characterized by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin. The term redhead (originally redd hede) has been in use since at least 1510. Cultural reactions have varied from ridicule to admiration; many common stereotypes exist regarding redheads and they are often portrayed as fiery-tempered. (See red hair).
Example Output: How does copper hair vary?

Example Input: Passage: Cork is home to one of Ireland's main national newspapers, the Irish Examiner (formerly the Cork Examiner). It also prints the Evening Echo, which for decades has been connected to the Echo Boys, who were poor and often homeless children who sold the newspaper. Today, the shouts of the vendors selling the Echo can still be heard in various parts of the city centre. One of the biggest free newspapers in the city is the Cork Independent. The city's University publishes the UCC Express and Motley magazine.
Example Output: What did the Irish Examiner change its name to?

Example Input: Passage: Combined with this influx of classical ideas was the invention of printing which facilitated dissemination of the printed word and democratized learning. These two things would later lead to the Protestant Reformation. Toward the end of the period, an era of discovery began (Age of Discovery). The rise of the Ottoman Empire, culminating in the Fall of Constantinople in 1453, eroded the last remnants of the Byzantine Empire and cut off trading possibilities with the east. Europeans were forced to seek new trading routes, leading to the expedition of Columbus to the Americas in 1492, and Vasco da Gama’s circumnavigation of India and Africa in 1498. Their discoveries strengthened the economy and power of European nations.
Example Output:
Which invention resulted in less widespread use of the printed word?
