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: Regardless of the way the tension between universities, individual scientists, and the scientific revolution itself is perceived, there was a discernible impact on the way that university education was constructed. Aristotelian epistemology provided a coherent framework not simply for knowledge and knowledge construction, but also for the training of scholars within the higher education setting. The creation of new scientific constructs during the scientific revolution, and the epistemological challenges that were inherent within this creation, initiated the idea of both the autonomy of science and the hierarchy of the disciplines. Instead of entering higher education to become a "general scholar" immersed in becoming proficient in the entire curriculum, there emerged a type of scholar that put science first and viewed it as a vocation in itself. The divergence between those focused on science and those still entrenched in the idea of a general scholar exacerbated the epistemological tensions that were already beginning to emerge.

SOLUTION: What type of epistemology served as the foundation of knowledge constructions and training students in universities?

PROBLEM: Passage: It is not clearly documented when the title of the Grand Duke was first introduced, but the importance of the Kiev principality was recognized after the death of Sviatoslav I in 972 and the ensuing struggle between Vladimir the Great and Yaropolk I. The region of Kiev dominated the state of Kievan Rus' for the next two centuries. The Grand Prince ("velikiy kniaz'") of Kiev controlled the lands around the city, and his formally subordinate relatives ruled the other cities and paid him tribute. The zenith of the state's power came during the reigns of Vladimir the Great (9801015) and Prince Yaroslav I the Wise (10191054). Both rulers continued the steady expansion of Kievan Rus' that had begun under Oleg.

SOLUTION: When was the title of Grand Duke introduced?

PROBLEM: Passage: But although it meets the definition of outer space, the atmospheric density within the first few hundred kilometers above the Karman line is still sufficient to produce significant drag on satellites. Most artificial satellites operate in this region called low Earth orbit and must fire their engines every few days to maintain orbit.[citation needed] The drag here is low enough that it could theoretically be overcome by radiation pressure on solar sails, a proposed propulsion system for interplanetary travel.[citation needed] Planets are too massive for their trajectories to be significantly affected by these forces, although their atmospheres are eroded by the solar winds.

SOLUTION:
How often does Earth's orbit position change?
