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: In 1607, English Chief Justice Sir Edward Coke said in the Case of Prohibitions (according to his own report) "that the law was the golden met-wand and measure to try the causes of the subjects; and which protected His Majesty in safety and peace: with which the King was greatly offended, and said, that then he should be under the law, which was treason to affirm, as he said; to which I said, that Bracton saith, quod Rex non debed esse sub homine, sed sub Deo et lege (That the King ought not to be under any man but under God and the law.)."

SOLUTION: Who called the law a golden met-wand during the sixteenth century?

PROBLEM: Passage: Vaudreuil and Montcalm were minimally resupplied in 1758, as the British blockade of the French coastline limited French shipping. The situation in New France was further exacerbated by a poor harvest in 1757, a difficult winter, and the allegedly corrupt machinations of Francois Bigot, the intendant of the territory. His schemes to supply the colony inflated prices and were believed by Montcalm to line his pockets and those of his associates. A massive outbreak of smallpox among western tribes led many of them to stay away from trading in 1758. While many parties to the conflict blamed others (the Indians blamed the French for bringing "bad medicine" as well as denying them prizes at Fort William Henry), the disease was probably spread through the crowded conditions at William Henry after the battle. Montcalm focused his meager resources on the defense of the St. Lawrence, with primary defenses at Carillon, Quebec, and Louisbourg, while Vaudreuil argued unsuccessfully for a continuation of the raiding tactics that had worked quite effectively in previous years.

SOLUTION: What was causing Old France to have issues with resupplying?

PROBLEM: Passage: For African Americans, the one-drop rule was a significant factor in ethnic solidarity. African Americans generally shared a common cause in society regardless of their multiracial admixture, or social/economic stratification. Additionally, African Americans found it, near, impossible to learn about their Indigenous American heritage as many family elders withheld pertinent genealogical information. Tracing the genealogy of African Americans can be a very difficult process, especially for descendants of Indigenous Americans, because African Americans who were slaves were forbidden to learn to read and write, and a majority of Indigenous Americans neither spoke English, nor read or wrote it.

SOLUTION:
What was a factor in ethnic solidarity for whites?
