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 Q]: Passage: Code points in the range U+D800–U+DBFF (1,024 code points) are known as high-surrogate code points, and code points in the range U+DC00–U+DFFF (1,024 code points) are known as low-surrogate code points. A high-surrogate code point (also known as a leading surrogate) followed by a low-surrogate code point (also known as a trailing surrogate) together form a surrogate pair used in UTF-16 to represent 1,048,576 code points outside BMP. High and low surrogate code points are not valid by themselves. Thus the range of code points that are available for use as characters is U+0000–U+D7FF and U+E000–U+10FFFF (1,112,064 code points). The value of these code points (i.e., excluding surrogates) is sometimes referred to as the character's scalar value.
[EX A]: What is a low-surrogate followed by a high-surrogate called?

[EX Q]: Passage: Australian citizens and residents from other parts of the nation now have automatic right of residence on the island after meeting these criteria (Immigration (Amendment No. 2) Act 2012). Australian citizens must carry either a passport or a Document of Identity to travel to Norfolk Island. Citizens of all other nations must carry a passport to travel to Norfolk Island even if arriving from other parts of Australia. Holders of Australian visas who travel to Norfolk Island have departed the Australian Migration Zone. Unless they hold a multiple-entry visa, the visa will have ceased; in which case they will require another visa to re-enter mainland Australia.
