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: A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was glaciated throughout the period, though it is uncertain if the ice sheets were a holdover from the Devonian or not. These conditions apparently had little effect in the deep tropics, where lush coal swamps flourished within 30 degrees of the northernmost glaciers. A mid-Carboniferous drop in sea-level precipitated a major marine extinction, one that hit crinoids and ammonites especially hard. This sea-level drop and the associated unconformity in North America separate the Mississippian Period from the Pennsylvanian period.
[EX A]: What dropped world wide at the begining of the Devonian?

[EX Q]: Passage: The economy of Himachal Pradesh is currently the third-fastest growing economy in India.[citation needed] Himachal Pradesh has been ranked fourth in the list of the highest per capita incomes of Indian states. This has made it one of the wealthiest places in the entire South Asia. Abundance of perennial rivers enables Himachal to sell hydroelectricity to other states such as Delhi, Punjab, and Rajasthan. The economy of the state is highly dependent on three sources: hydroelectric power, tourism, and agriculture.[citation needed]
[EX A]: What is the third fastest growing economy in Delhi?

[EX Q]: Passage: Barred by the government from settling in New France, Huguenots led by Jessé de Forest, sailed to North America in 1624 and settled instead in the Dutch colony of New Netherland (later incorporated into New York and New Jersey); as well as Great Britain's colonies, including Nova Scotia. A number of New Amsterdam's families were of Huguenot origin, often having emigrated as refugees to the Netherlands in the previous century. In 1628 the Huguenots established a congregation as L'Église française à la Nouvelle-Amsterdam (the French church in New Amsterdam). This parish continues today as L'Eglise du Saint-Esprit, part of the Episcopal (Anglican) communion, and welcomes Francophone New Yorkers from all over the world. Upon their arrival in New Amsterdam, Huguenots were offered land directly across from Manhattan on Long Island for a permanent settlement and chose the harbor at the end of Newtown Creek, becoming the first Europeans to live in Brooklyn, then known as Boschwick, in the neighborhood now known as Bushwick.
[EX A]:
