TASK DEFINITION: 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.
PROBLEM: Passage: The Internet was developed as a network between government research laboratories and participating departments of universities. By the late 1980s, a process was set in place towards public, commercial use of the Internet. The remaining restrictions were removed by 1995, 4 years after the introduction of the World Wide Web.

SOLUTION: What was developed as a way for various universities to communicate with each other?

PROBLEM: Passage: The British failures in North America, combined with other failures in the European theater, led to the fall from power of Newcastle and his principal military advisor, the Duke of Cumberland. Newcastle and Pitt joined in an uneasy coalition in which Pitt dominated the military planning. He embarked on a plan for the 1758 campaign that was largely developed by Loudoun. He had been replaced by Abercrombie as commander in chief after the failures of 1757. Pitt's plan called for three major offensive actions involving large numbers of regular troops, supported by the provincial militias, aimed at capturing the heartlands of New France. Two of the expeditions were successful, with Fort Duquesne and Louisbourg falling to sizable British forces.

SOLUTION: What led to Newcastle's rise to power as military advisor?

PROBLEM: Passage: It is recognised that an epidemiological account of the plague is as important as an identification of symptoms, but researchers are hampered by the lack of reliable statistics from this period. Most work has been done on the spread of the plague in England, and even estimates of overall population at the start vary by over 100% as no census was undertaken between the time of publication of the Domesday Book and the year 1377. Estimates of plague victims are usually extrapolated from figures from the clergy.

SOLUTION:
In what year did the plague begin in England?
