TASK DEFINITION: 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.
PROBLEM: Passage: The strength of the Viking influence on Old English appears from the fact that the indispensable elements of the language - pronouns, modals, comparatives, pronominal adverbs (like "hence" and "together"), conjunctions and prepositions - show the most marked Danish influence; the best evidence of Scandinavian influence appears in the extensive word borrowings for, as Jespersen indicates, no texts exist in either Scandinavia or in Northern England from this time to give certain evidence of an influence on syntax. The change to Old English from Old Norse was substantive, pervasive, and of a democratic character. Old Norse and Old English resembled each other closely like cousins and with some words in common, they roughly understood each other; in time the inflections melted away and the analytic pattern emerged. It is most “important to recognize that in many words the English and Scandinavian language differed chiefly in their inflectional elements. The body of the word was so nearly the same in the two languages that only the endings would put obstacles in the way of mutual understanding. In the mixed population which existed in the Danelaw these endings must have led to much confusion, tending gradually to become obscured and finally lost.” This blending of peoples and languages happily resulted in “simplifying English grammar.”

SOLUTION: What language was influenced by English as a result of Viking invasions?

PROBLEM: Passage: After independence, the Chief Commissioner's Province of H.P. came into being on 15 April 1948 as a result of integration of 28 petty princely states (including feudal princes and zaildars) in the promontories of the western Himalaya, known in full as the Simla Hills States and four Punjab southern hill states by issue of the Himachal Pradesh (Administration) Order, 1948 under Sections 3 and 4 of the Extra-Provincial Jurisdiction Act, 1947 (later renamed as the Foreign Jurisdiction Act, 1947 vide A.O. of 1950). The State of Bilaspur was merged in the Himachal Pradesh on 1 April 1954 by the Himachal Pradesh and Bilaspur (New State) Act, 1954. Himachal became a part C state on 26 January 1950 with the implementation of the Constitution of India and the Lt. Governor was appointed. Legislative Assembly was elected in 1952. Himachal Pradesh became a union territory on 1 November 1956. Following area of Punjab State namely Simla, Kangra, Kulu and Lahul and Spiti Districts, Nalagarh tehsil of Ambala District, Lohara, Amb and Una kanungo circles, some area of Santokhgarh kanungo circle and some other specified area of Una tehsil of Hoshiarpur District besides some parts of Dhar Kalan Kanungo circle of Pathankot tehsil of Gurdaspur District; were merged with Himachal Pradesh on 1 November 1966 on enactment of Punjab Reorganisation Act, 1966 by the Parliament. On 18 December 1970, the State of Himachal Pradesh Act was passed by Parliament and the new state came into being on 25 January 1971. Thus Himachal emerged as the 18th state of the Indian Union.

SOLUTION: On what date did western Himalaya become a union territory?

PROBLEM: Passage: The UAP had been formed as a new conservative alliance in 1931, with Labor defector Joseph Lyons as its leader. The stance of Lyons and other Labor rebels against the more radical proposals of the Labor movement to deal the Great Depression had attracted the support of prominent Australian conservatives. With Australia still suffering the effects of the Great Depression, the newly formed party won a landslide victory at the 1931 Election, and the Lyons Government went on to win three consecutive elections. It largely avoided Keynesian pump-priming and pursued a more conservative fiscal policy of debt reduction and balanced budgets as a means of stewarding Australia out of the Depression. Lyons' death in 1939 saw Robert Menzies assume the Prime Ministership on the eve of war. Menzies served as Prime Minister from 1939 to 1941 but resigned as leader of the minority World War II government amidst an unworkable parliamentary majority. The UAP, led by Billy Hughes, disintegrated after suffering a heavy defeat in the 1943 election.

SOLUTION:
What economic event influenced the 1943 election?
