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: The first extant Estonian book is a bilingual German-Estonian translation of the Lutheran catechism by S. Wanradt and J. Koell dating to 1535, during the Protestant Reformation period. An Estonian grammar book to be used by priests was printed in German in 1637. The New Testament was translated into southern Estonian in 1686 (northern Estonian, 1715). The two languages were united based on northern Estonian by Anton thor Helle.

A: Who wrote the last Estonian book?

Q: Passage: Old English was not static, and its usage covered a period of 700 years, from the Anglo-Saxon settlement of Britain in the 5th century to the late 11th century, some time after the Norman invasion. While indicating that the establishment of dates is an arbitrary process, Albert Baugh dates Old English from 450 to 1150, a period of full inflections, a synthetic language. Perhaps around 85 per cent of Old English words are no longer in use, but those that survived, to be sure, are basic elements of Modern English vocabulary.

A: Where did Anglo-Saxons settle in the 500's?

Q: Passage: In 1897, Victoria had written instructions for her funeral, which was to be military as befitting a soldier's daughter and the head of the army, and white instead of black. On 25 January, Edward VII, the Kaiser and Prince Arthur, Duke of Connaught, helped lift her body into the coffin. She was dressed in a white dress and her wedding veil. An array of mementos commemorating her extended family, friends and servants were laid in the coffin with her, at her request, by her doctor and dressers. One of Albert's dressing gowns was placed by her side, with a plaster cast of his hand, while a lock of John Brown's hair, along with a picture of him, was placed in her left hand concealed from the view of the family by a carefully positioned bunch of flowers. Items of jewellery placed on Victoria included the wedding ring of John Brown's mother, given to her by Brown in 1883. Her funeral was held on Saturday, 2 February, in St George's Chapel, Windsor Castle, and after two days of lying-in-state, she was interred beside Prince Albert in Frogmore Mausoleum at Windsor Great Park. As she was laid to rest at the mausoleum, it began to snow.

A:
Which three people helped lift Victoria's body into the coffin?
