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 Q]: Passage: The ultimate substantive legacy of Principia Mathematica is mixed. It is generally accepted that Kurt Gödel's incompleteness theorem of 1931 definitively demonstrated that for any set of axioms and inference rules proposed to encapsulate mathematics, there would in fact be some truths of mathematics which could not be deduced from them, and hence that Principia Mathematica could never achieve its aims. However, Gödel could not have come to this conclusion without Whitehead and Russell's book. In this way, Principia Mathematica's legacy might be described as its key role in disproving the possibility of achieving its own stated goals. But beyond this somewhat ironic legacy, the book popularized modern mathematical logic and drew important connections between logic, epistemology, and metaphysics.
[EX A]: What is the general consensus of the axioms and inference rules not declared in Principia Mathematica?

[EX Q]: 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 A]: What did Dell enjoy from 1996 to 2004?

[EX Q]: Passage: The first six presidents of the United States did not make extensive use of the veto power: George Washington only vetoed two bills, James Monroe one, and John Adams, Thomas Jefferson and John Quincy Adams none. James Madison, a firm believer in a strong executive, vetoed seven bills. None of the first six Presidents, however, used the veto to direct national policy. It was Andrew Jackson, the seventh President, who was the first to use the veto as a political weapon. During his two terms in office, he vetoed twelve bills—more than all of his predecessors combined. Furthermore, he defied the Supreme Court in enforcing the policy of ethnically cleansing Native American tribes ("Indian Removal"); he stated (perhaps apocryphally), "John Marshall has made his decision. Now let him enforce it!"
[EX A]:
Which president vetoed six bills?
