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.

Ex Input:
Passage: From 1997 to 2004, Dell enjoyed steady growth and it gained market share from competitors even during industry slumps. During the same period, rival PC vendors such as Compaq, Gateway, IBM, Packard Bell, and AST Research struggled and eventually left the market or were bought out. Dell surpassed Compaq to become the largest PC manufacturer in 1999. Operating costs made up only 10 percent of Dell's $35 billion in revenue in 2002, compared with 21 percent of revenue at Hewlett-Packard, 25 percent at Gateway, and 46 percent at Cisco. In 2002, when Compaq merged with Hewlett Packard (the fourth-place PC maker), the newly combined Hewlett Packard took the top spot but struggled and Dell soon regained its lead. Dell grew the fastest in the early 2000s.

Ex Output:
What did Dell enjoy from 1996 to 2004?


Ex Input:
Passage: During the Middle Ages, Thuringia was situated at the border between Germanic and Slavic territories, marked by the Saale river. The Ostsiedlung movement led to the assimilation of Slavic people between the 11th and the 13th century under German rule. The population growth increased during the 18th century and stayed high until World War I, before it slowed within the 20th century and changed to a decline since 1990. Since the beginning of Urbanisation around 1840, the Thuringian cities have higher growth rates resp. smaller rates of decline than rural areas (many villages lost half of their population since 1950, whereas the biggest cities (Erfurt and Jena) keep growing).

Ex Output:
Where was Thuringia attacking in the Middle Ages?


Ex Input:
Passage: In 1959, an international gathering of over 185 judges, lawyers, and law professors from 53 countries, meeting in New Delhi and speaking as the International Commission of Jurists, made a declaration as to the fundamental principle of the rule of law. This was the Declaration of Delhi. They declared that the rule of law implies certain rights and freedoms, that it implies an independent judiciary, and that it implies social, economic and cultural conditions conducive to human dignity. The Declaration of Delhi did not, however, suggest that the rule of law requires legislative power to be subject to judicial review.

Ex Output:

Who made a declaration about the principle of rule of law in the nineteenth century?
