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: New Zealand has a strong hunting culture. The islands making up New Zealand originally had no land mammals apart from bats. However, once Europeans arrived, game animals were introduced by acclimatisation societies to provide New Zealanders with sport and a hunting resource. Deer, pigs, goats, rabbits, hare, tahr and chamois all adapted well to the New Zealand terrain, and with no natural predators, their population exploded. Government agencies view the animals as pests due to their effects on the natural environment and on agricultural production, but hunters view them as a resource.

SOLUTION: What mammal was the only one that existed originally in Europe?

PROBLEM: Passage: Between 1346 and 1354, Tai Situ Changchub Gyaltsen toppled the Sakya and founded the Phagmodrupa Dynasty. The following 80 years saw the founding of the Gelug school (also known as Yellow Hats) by the disciples of Je Tsongkhapa, and the founding of the important Ganden, Drepung and Sera monasteries near Lhasa. However, internal strife within the dynasty and the strong localism of the various fiefs and political-religious factions led to a long series of internal conflicts. The minister family Rinpungpa, based in Tsang (West Central Tibet), dominated politics after 1435. In 1565 they were overthrown by the Tsangpa Dynasty of Shigatse which expanded its power in different directions of Tibet in the following decades and favoured the Karma Kagyu sect.

SOLUTION: Who topped the Sakya between 1436 and 1534?

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 François 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?
