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: Following the treaty, King George III issued the Royal Proclamation of 1763 on October 7, 1763, which outlined the division and administration of the newly conquered territory, and to some extent continues to govern relations between the government of modern Canada and the First Nations. Included in its provisions was the reservation of lands west of the Appalachian Mountains to its Indian population, a demarcation that was at best a temporary impediment to a rising tide of westward-bound settlers. The proclamation also contained provisions that prevented civic participation by the Roman Catholic Canadians. When accommodations were made in the Quebec Act in 1774 to address this and other issues, religious concerns were raised in the largely Protestant Thirteen Colonies over the advance of "popery"; the Act maintained French Civil law, including the seigneurial system, a medieval code soon to be removed from France within a generation by the French Revolution.

Ex Output:
Who never issued the Royal Proclamation of 1763?


Ex Input:
Passage: Hyperbaric (high-pressure) medicine uses special oxygen chambers to increase the partial pressure of O
2 around the patient and, when needed, the medical staff. Carbon monoxide poisoning, gas gangrene, and decompression sickness (the 'bends') are sometimes treated using these devices. Increased O
2 concentration in the lungs helps to displace carbon monoxide from the heme group of hemoglobin. Oxygen gas is poisonous to the anaerobic bacteria that cause gas gangrene, so increasing its partial pressure helps kill them. Decompression sickness occurs in divers who decompress too quickly after a dive, resulting in bubbles of inert gas, mostly nitrogen and helium, forming in their blood. Increasing the pressure of O
2 as soon as possible is part of the treatment.

Ex Output:
What medicines to do hyperbaric chambers use?


Ex Input:
Passage: The first Code of Canon Law, 1917, was mostly for the Roman Rite, with limited application to the Eastern Churches. After the Second Vatican Council, (1962 - 1965), another edition was published specifically for the Roman Rite in 1983. Most recently, 1990, the Vatican produced the Code of Canons of the Eastern Churches which became the 1st code of Eastern Catholic Canon Law.

Ex Output:

What was published prior to 1917?
