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

[EX Q]: Passage: The term "Sumerian" is the common name given to the ancient non-Semitic inhabitants of Mesopotamia, Sumer, by the Semitic Akkadians. The Sumerians referred to themselves as ùĝ saĝ gíg-ga (cuneiform: 𒌦 𒊕 𒈪 𒂵), phonetically /uŋ saŋ giga/, literally meaning "the black-headed people", and to their land as ki-en-gi(-r) ('place' + 'lords' + 'noble'), meaning "place of the noble lords". The Akkadian word Shumer may represent the geographical name in dialect, but the phonological development leading to the Akkadian term šumerû is uncertain. Hebrew Shinar, Egyptian Sngr, and Hittite Šanhar(a), all referring to southern Mesopotamia, could be western variants of Shumer.

[EX Q]: Passage: The terms used to define Greekness have varied throughout history but were never limited or completely identified with membership to a Greek state. By Western standards, the term Greeks has traditionally referred to any native speakers of the Greek language, whether Mycenaean, Byzantine or modern Greek. Byzantine Greeks called themselves Romioi and considered themselves the political heirs of Rome, but at least by the 12th century a growing number of those educated, deemed themselves the heirs of ancient Greece as well, although for most of the Greek speakers, "Hellene" still meant pagan. On the eve of the Fall of Constantinople the Last Emperor urged his soldiers to remember that they were the descendants of Greeks and Romans.

[EX Q]: Passage: The political reforms of Peter the Great (Пётр Вели́кий, Pyótr Velíkiy) were accompanied by a reform of the alphabet, and achieved their goal of secularization and Westernization. Blocks of specialized vocabulary were adopted from the languages of Western Europe. By 1800, a significant portion of the gentry spoke French daily, and German sometimes. Many Russian novels of the 19th century, e.g. Leo Tolstoy's (Лев Толсто́й) War and Peace, contain entire paragraphs and even pages in French with no translation given, with an assumption that educated readers would not need one.
[EX A]:
In what year did Peter the Great come to power?
