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.

Input: Consider Input: Passage: Before the French and Indian War, the Appalachian Mountains laid on the indeterminate boundary between Britain's colonies along the Atlantic and French areas centered in the Mississippi basin. After the French and Indian War, the Proclamation of 1763 restricted settlement for Great Britain's thirteen original colonies in North America to east of the summit line of the mountains (except in the northern regions where the Great Lakes formed the boundary). Although the line was adjusted several times to take frontier settlements into account and was impossible to enforce as law, it was strongly resented by backcountry settlers throughout the Appalachians. The Proclamation Line can be seen as one of the grievances which led to the American Revolutionary War. Many frontier settlers held that the defeat of the French opened the land west of the mountains to English settlement, only to find settlement barred by the British King's proclamation. The backcountry settlers who fought in the Illinois campaign of George Rogers Clark were motivated to secure their settlement of Kentucky.

Output: When did the French and Indian war begin?


Input: Consider Input: Passage: Another milestone in the early development of Baptist doctrine was in 1638 with John Spilsbury, a Calvinistic minister who helped to promote the strict practice of believer's baptism by immersion. According to Tom Nettles, professor of historical theology at Southern Baptist Theological Seminary, "Spilsbury's cogent arguments for a gathered, disciplined congregation of believers baptized by immersion as constituting the New Testament church gave expression to and built on insights that had emerged within separatism, advanced in the life of John Smyth and the suffering congregation of Thomas Helwys, and matured in Particular Baptists."

Output: When did John Spilsbury create the strict practice of immersion?


Input: Consider Input: Passage: Many of the farms in the Western Cape province in South Africa still bear French names. Many families, today mostly Afrikaans-speaking, have surnames indicating their French Huguenot ancestry. Examples include: Blignaut, Cilliers, de Klerk (Le Clercq), de Villiers, du Plessis, Du Preez (Des Pres), du Randt (Durand), du Toit, Duvenhage(Du Vinage), Franck, Fouche, Fourie (Fleurit), Gervais, Giliomee (Guilliaume), Gous/Gouws (Gauch), Hugo, Jordaan (Jourdan), Joubert, Kriek, Labuschagne (la Buscagne), le Roux, Lombard, Malan, Malherbe, Marais, Maree, Minnaar (Mesnard), Nel (Nell),Naude', Nortje (Nortier), Pienaar (Pinard), Retief (Retif), Rossouw (Rousseau), Taljaard (Taillard), TerBlanche, Theron, Viljoen (Villion) and Visagie (Visage). The wine industry in South Africa owes a significant debt to the Huguenots, some of whom had vineyards in France, or were brandy distillers, and used their skills in their new home.


Output: What prominent South African family had a vineyard in France?
