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 Input:
Passage: From 21 April 1944 until her accession, Elizabeth's arms consisted of a lozenge bearing the royal coat of arms of the United Kingdom differenced with a label of three points argent, the centre point bearing a Tudor rose and the first and third a cross of St George. Upon her accession, she inherited the various arms her father held as sovereign. The Queen also possesses royal standards and personal flags for use in the United Kingdom, Canada, Australia, New Zealand, Jamaica, Barbados, and elsewhere.

Ex Output:
How many points does Elizabeth's arms bear on her argent after her accession?

Passage: Extension causes the rock units as a whole to become longer and thinner. This is primarily accomplished through normal faulting and through the ductile stretching and thinning. Normal faults drop rock units that are higher below those that are lower. This typically results in younger units being placed below older units. Stretching of units can result in their thinning; in fact, there is a location within the Maria Fold and Thrust Belt in which the entire sedimentary sequence of the Grand Canyon can be seen over a length of less than a meter. Rocks at the depth to be ductilely stretched are often also metamorphosed. These stretched rocks can also pinch into lenses, known as boudins, after the French word for "sausage", because of their visual similarity.

Ex Output:
What is another word for thinning rocks in French?

Passage: On 17 March 1883, she fell down some stairs at Windsor, which left her lame until July; she never fully recovered and was plagued with rheumatism thereafter. Brown died 10 days after her accident, and to the consternation of her private secretary, Sir Henry Ponsonby, Victoria began work on a eulogistic biography of Brown. Ponsonby and Randall Davidson, Dean of Windsor, who had both seen early drafts, advised Victoria against publication, on the grounds that it would stoke the rumours of a love affair. The manuscript was destroyed. In early 1884, Victoria did publish More Leaves from a Journal of a Life in the Highlands, a sequel to her earlier book, which she dedicated to her "devoted personal attendant and faithful friend John Brown". On the day after the first anniversary of Brown's death, Victoria was informed by telegram that her youngest son, Leopold, had died in Cannes. He was "the dearest of my dear sons", she lamented. The following month, Victoria's youngest child, Beatrice, met and fell in love with Prince Henry of Battenberg at the wedding of Victoria's granddaughter Princess Victoria of Hesse and by Rhine to Henry's brother Prince Louis of Battenberg. Beatrice and Henry planned to marry, but Victoria opposed the match at first, wishing to keep Beatrice at home to act as her companion. After a year, she was won around to the marriage by Henry and Beatrice's promise to remain living with and attending her.

Ex Output:

What year didn't Victoria fall down the stairs at Windsor?
