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.

[Q]: Passage: Unlike the Baroque style that it replaced, which was mostly used for palaces and churches, and had little representation in the British colonies, simpler Georgian styles were widely used by the upper and middle classes. Perhaps the best remaining house is the pristine Hammond-Harwood House (1774) in Annapolis, Maryland, designed by the colonial architect William Buckland and modelled on the Villa Pisani at Montagnana, Italy as depicted in Andrea Palladio's I quattro libri dell'architettura ("Four Books of Architecture").
[A]: What style was widely represented in British colonies?

[Q]: 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."
[A]: When did John Spilsbury create the strict practice of immersion?

[Q]: Passage: Under the Scotland Act 1998, ordinary general elections for the Scottish Parliament are held on the first Thursday in May every four years (1999, 2003, 2007 and so on). The date of the poll may be varied by up to one month either way by the Monarch on the proposal of the Presiding Officer. If the Parliament itself resolves that it should be dissolved (with at least two-thirds of the Members voting in favour), or if the Parliament fails to nominate one of its members to be First Minister within 28 days of a General Election or of the position becoming vacant, the Presiding Officer proposes a date for an extraordinary general election and the Parliament is dissolved by the Queen by royal proclamation. Extraordinary general elections are in addition to ordinary general elections, unless held less than six months before the due date of an ordinary general election, in which case they supplant it. The following ordinary election reverts to the first Thursday in May, a multiple of four years after 1999 (i.e., 5 May 2011, 7 May 2015, etc.).
[A]:
Under the Scotland Act 1988, ordinary general elections are held when?
