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: The island experienced large-scale immigration over the 20th century, especially after the Second World War. Bermuda has a diverse population including both those with relatively deep roots in Bermuda extending back for centuries, and newer communities whose ancestry results from recent immigration, especially from Britain, North America, the West Indies, and the Portuguese Atlantic islands (especially the Azores), although these groups are steadily merging. About 46% of the population identified themselves with Bermudian ancestry in 2010, which was a decrease from the 51% who did so in the 2000 census. Those identifying with British ancestry dropped by 1% to 11% (although those born in Britain remain the largest non-native group at 3,942 persons). The number of people born in Canada declined by 13%. Those who reported West Indian ancestry were 13%. The number of people born in the West Indies actually increased by 538. A significant segment of the population is of Portuguese ancestry (10%), the result of immigration over the past 160 years, of whom 79% have residency status.

Output: During what century was the diverse immigration?


Input: Consider Input: Passage: Following al-Farabi's lead, Avicenna initiated a full-fledged inquiry into the question of being, in which he distinguished between essence (Mahiat) and existence (Wujud). He argued that the fact of existence can not be inferred from or accounted for by the essence of existing things, and that form and matter by themselves cannot interact and originate the movement of the universe or the progressive actualization of existing things. Existence must, therefore, be due to an agent-cause that necessitates, imparts, gives, or adds existence to an essence. To do so, the cause must be an existing thing and coexist with its effect.

Output: Who followed Avicenna's leadand investigated the question of being?


Input: Consider Input: Passage: The war in North America officially ended with the signing of the Treaty of Paris on 10 February 1763, and war in the European theatre of the Seven Years' War was settled by the Treaty of Hubertusburg on 15 February 1763. The British offered France the choice of surrendering either its continental North American possessions east of the Mississippi or the Caribbean islands of Guadeloupe and Martinique, which had been occupied by the British. France chose to cede the former, but was able to negotiate the retention of Saint Pierre and Miquelon, two small islands in the Gulf of St. Lawrence, along with fishing rights in the area. They viewed the economic value of the Caribbean islands' sugar cane to be greater and easier to defend than the furs from the continent. The contemporaneous French philosopher Voltaire referred to Canada disparagingly as nothing more than a few acres of snow. The British, for their part, were happy to take New France, as defence of their North American colonies would no longer be an issue and also because they already had ample places from which to obtain sugar. Spain, which traded Florida to Britain to regain Cuba, also gained Louisiana, including New Orleans, from France in compensation for its losses. Great Britain and Spain also agreed that navigation on the Mississippi River was to be open to vessels of all nations.


Output: When did the North American French and Indian War begin?
